Radiation exposure during C-arm-guided (fluoroscopy) small animal orthopaedic surgeryOriginal PaperS. Sung, S. Lim, K. Min, Y. Jung, Y. Cho, M. Kim, N. Kim, K. LeeVet Med - Czech, 2018, 63(11):527-531 | DOI: 10.17221/15/2018-VETMED The purpose of the current study was to investigate the radiation exposure level of surgeons performing C-arm guided small animal orthopaedic surgery using thermoluminescent dosimeters located inside and outside personnel shielding devices at major body parts. A prospective study was conducted to measure the radiation exposure dose of individuals in three positions (first assistant, operating surgeon and anaesthesiologist) using thermoluminescent dosimeters placed inside and outside protective devices. The lead equivalent protective devices included panorama mask, thyroid shield, apron and arm shield placed at five anatomic sites (eye, thyroid, breast, gonad and hand). Radiation exposure was measured during 12 surgical procedures with mean kVp of 51 and mean mAs of 1.6. The equivalent doses for thyroid, breast and gonad (outside/inside in mSv) were 1.75/0.58, 2.01/0.13 and 3.03/0.11, respectively, for the first assistant and 1.69/1.46, 4.82/0.35 and 5.25/0.22 for the operating surgeon. The dose of eye, thyroid, breast, gonad and arm for the anaesthesiologist were 0.61/0.51, 0.35/0.3, 0.67/0.34, 0.72/0.29 and 0.62/0.35, respectively. The exposure dose to gonads outside the lead protection showed the highest values in all participants. With lead protection, there was a significant reduction in the exposure dose to the gonads (first assistant, 96%; operating surgeon, 96%; anaesthesiologist, 60%). These results suggest that a radiation shield is essential in veterinary surgery with C-arms, particularly for gonad protection. In addition, these results demonstrate that exposure dose decreases with increasing distance from the C-arm machine. |
Effects of potassium fertilisation on late potato blight and yield - short communicationShort CommunicationJolanta Kowalska, Dariusz DrożdżyńskiPlant Protect. Sci., 2018, 54(2):87-91 | DOI: 10.17221/79/2017-PPS Potato yields and infestation by P. infestans are related to the supply of potassium. Potassium was applied as soil fertilisation combined with split foliar applications or only as split foliar treatments at a maximum dose of 150 kg/ha K2O in both strategies, Lord and Ditta cultivars were used. Additionally, water spraying was included as an alternative treatment in order to maintain uniform moisture in the rows of plants. Plants fertilised with foliar spraying only were more infested than plants fertilised with combined methods. The fertiliser increased the protection impact of copper treatments against P. infestans. This may suggest a possible synergistic effect in reducing the symptoms of the disease, however not always statistically significant in both cultivars. Plants sprayed with water but without soil application of fertiliser showed a statistically significantly higher infestation rate, both in Lord and Ditta cultivars, compared to plants with soil application of fertiliser but without watering. |
Consumption of atmospheric methane by soil in a lowland broadleaf mixed forestOriginal PaperJiří DU©EK, Manuel ACOSTA, Stanislav STELLNER, Ladislav ©IGUT, Marian PAVELKAPlant Soil Environ., 2018, 64(8):400-406 | DOI: 10.17221/183/2018-PSE Soils of forest ecosystems can release or consume methane (CH4) depending on their specific hydrological regime. Our study reported the consumption of CH4 by soil in a lowland broadleaf mixed temperate forest in the Czech Republic (Central Europe). The motivation of our study was to determine the importance of CH4 fluxes in context of carbon dioxide (CO2) fluxes of a broadleaf mixed forest. CH4 and CO2 emissions from the soil were measured during the 2016 vegetation season on a long transect applying the chamber technique. The average daily consumption of atmospheric CH4 by the forest soil ranged from 0.83 to 1.15 mg CH4-C/m2/day. This consumption of CH4 during summer and autumn periods was not significantly affected by soil temperature and soil moisture. However, during spring period the consumption of CH4 was positively significantly affected by soil temperature and moisture. Estimated amount of carbon (CH4-C) consumed by the forest soil makes up a very small part of carbon (CO2-C) participated in the ecosystem carbon cycle. |
The role of biofertilizers in improving vegetative growth, yield and fruit quality of appleOriginal PaperWalid Fediala Abd El-Gleel Mosa, Lidia Sas Paszt, Mateusz Fr±c, Paweł Trzciński, Waldemar Treder, Krzysztof KlamkowskiHort. Sci. (Prague), 2018, 45(4):173-180 | DOI: 10.17221/101/2017-HORTSCI Apple trees which grafted on M.M. 106 stocks were planted at the beginning of spring 2014 in pots at the Research Institute of Horticulture in Skierniewice, Poland. The used treatments in the experiment were: NPK fertilization and bioproducts: Fertigo (Manure), Micosat, Humus UP, Humus Active + Aktywit PM, BioFeed Quality, BioFeed Amin, Vinassa, Florovit Natura and Florovit Eko. In the spring, these treatments were applied to apple trees alone or enriched with Pantoea sp., Pseudomonas fluorescens, Klebsiella oxytoca and Rhizobium sp. bacterial strains. Growth, yield and fruit quality parameters were evaluated. The results revealed that photosynthetic rate was greatly improved by the addition of bacteria to Fertigo (Manure), Micosat, Humus UP and Humus Active + Aktywit PM as compared to NPK. Tree trunk thickness was significantly enhanced with Vinassa, Florovit Natura and Florovit Eko enriched with bacteria. The application of bacterial strains increased the effectiveness of Fertigo (Manure), Humus UP, Humus Active + Aktywit PM, Biofeed Amin and Yeast in increasing significantly number and weight of fruits as compared to NPK. |
Attractiveness of Picea pungens to the bark beetle species Ips amitinus (Eichh.) and Pityogenes chalcographus (L.)Original PaperE. Kula, R. Kajfosz, J. PolívkaJ. For. Sci., 2013, 59(12):493-502 | DOI: 10.17221/70/2013-JFS Only two cambioxylophagous species (Ips amitinus and Pityogenes chalcographus) were found on sections of Picea pungens and Picea abies that belong to economically important pests of Norway spruce. Representatives of the Isarthron sp. (Cerambycidae) were developed on the examined sections of both P. abies and P. pungens. The monitoring of attractiveness of the spruce species P. pungens and P. abies to cambioxylophages revealed that P. pungens was more intensively attacked by I. amitinus while P. chalcographus was more abundant on P. abies. Both bark beetle species preferred shaded parts of tree trunks, although their development was more successful on the sun-exposed side. On P. pungens, abundance of P. chalcographus decreased and abundance of I. amitinus increased with increasing trunk volume. Blue spruce was more attractive to Isarthron sp. compared to Norway spruce. |
Ultrasonic microwave-assisted extraction of polyphenols, flavonoids, triterpenoids, and vitamin C from Clinacanthus nutansFood Technology and Economy, Engineering and Physical PropertiesQun Yu, Chuan Li, Zhenhua Duan, 2*, Bing Liu, Weiwen Duan, Feifei ShangCzech J. Food Sci., 2017, 35(1):89-94 | DOI: 10.17221/82/2016-CJFS Polyphenols, flavonoids, triterpenoids, and vitamin C from Clinacanthus nutans were extracted by an ultrasonic microwave-assisted method. The optimal extraction conditions were established in distilled water, solid-liquid ratio 1 : 55 g/ml, irradiation power 90 W, and extraction cycle with 75 seconds. Results revealed that the solid-liquid ratio exerted a significant effect on polyphenols, whereas the irradiation power played a key role in the extraction of flavonoids, triterpenoids, and vitamin C. Under these conditions the extraction yield of each component was: polyphenols 8.893, flavonoids 25 936, triterpenoids 16 789, and vitamin C 0.166 mg/g. These results showed that the ultrasonic microwave-assisted extraction was an efficient technology to extract bioactive substances from Clinacanthus nutans and Clinacanthus nutans could potentially be a source of natural antioxidants. |
Removal of a tracheal foreign body by intercostal thoracotomy in a catCase ReportS. Cagatay, A.P. Gokce, G. YesilovaliVet Med - Czech, 2018, 63(9):438-442 | DOI: 10.17221/75/2018-VETMED In this case report, we describe a five-year-old, mixed-breed, neutered male cat weighing 5.7 kg, that was referred to the Near East University Animal Hospital with complaints of dyspnoea, cough and lack of appetite over the preceding two days. Clinical examination revealed marked wheezing during expiration, severe shortness of breath and associated cyanosis. A blood sample was drawn for full blood count, serum biochemical and blood gas analyses. Laterolateral and ventrodorsal radiographic images of the thorax and abdominal region were obtained. A radiopaque foreign body measuring 3 × 9 × 13 mm was detected at the carina of the trachea, aligned in the midst of the fifth-sixth intercostal space. Considering that this foreign body obstructed the tracheal lumen almost completely and had been creating pressure on the tracheal wall for at least two days and also with the aim of preventing potential complications (tracheal rupture, laceration, etc.), after repeated unsuccessful interventions to minimise the time spent under anaesthesia, the object was removed by intercostal thoracotomy. The subject was discharged on the sixth postoperative day and regained its normal state within a short time. |
Lignin biosynthesis regulated by the antisense 4CL gene in alfalfaShort CommunicationJing MENG, Caona LI, Manlin ZHAO, Cheng WANG, Yi RU, Zhixin CUI, Yang HANCzech J. Genet. Plant Breed., 2018, 54(1):26-29 | DOI: 10.17221/23/2017-CJGPB The Antisense 4CL gene was transfected into alfalfa through Agrobacterium-mediated transfer. The test results indicated that the antisense 4CL gene was successfully integrated into the genome DNA of alfalfa and was stably transmitted to the offspring. Compared to the wild-type plants, the lignin content of T0 and T1 generation plants was reduced by 45.77% and 31.97%, respectively; there were no significant differences in height and weight of T0 and T1 plants, compared to the wild-type plants. However, the transgenic plant differed from the wild-type plant by softer stems and leaves, larger leaves, fewer flowers and a fewer seeds. The T0 line was susceptible to disease infection, but significantly improved in the second year. The results suggest that the 4CL gene from Amorpha fruticosa can be used to regulate lignin biosynthesis in transgenic forage crops. |
Antagonistic activity of selected fungi of the soil environment of carrotOriginal PaperElżbieta PATKOWSKA, Agnieszka JAMIOŁKOWSKA, Marzena BŁAŻEWICZ-WO¬NIAKPlant Soil Environ., 2018, 64(2):58-63 | DOI: 10.17221/792/2017-PSE The present studies aim at determining the antagonistic effect of selected fungi species occurring in the soil under carrot cultivation towards Altenaria dauci (J.G. Kühn) J.W. Groves & Skolko, Alternaria radicina Meier, Drechsler & E.D. Eddy, Fusarium oxysporum E.F. Sm & Swingle, Rhizoctonia solani J.G. Kühn and Sclerotinia sclerotiorum (Lib.) de Bary. The field experiment considered cover crops (oats, tansy phacelia and vetch). The control consisted of traditional carrot cultivation (without cover crops). Statistically, the smallest population of fungi was found in 1 g of soil dry weight after the application of oats, and a slightly bigger - after tansy phacelia and vetch. The largest population of fungi was obtained in the traditional cultivation of carrot. Cover crops contributed to the increase of the population of antagonistic Clonostachys spp., Myrothecium spp., Penicillium spp. and Trichoderma spp. in the soil. Regardless of the experimental treatment, those antagonistic fungi were the most effective in limiting the growth of S. sclerotiorum, A. dauci and A. radicina. The effect of those fungi was a little smaller towards F. oxysporum and R. solani. Oats as a cover crop had the best effect on the antagonistic activity of the studied fungi occurring in the soil environment of carrot. |
Sulphur status in agricultural soils determined using the Mehlich 3 methodOriginal PaperJiří ZBÍRAL, Michaela SMATANOVÁ, Pavel NĚMECPlant Soil Environ., 2018, 64(6):255-259 | DOI: 10.17221/142/2018-PSE Several sets of soil samples were chosen to demonstrate the applicability of the Mehlich 3 extractant for the determination of sulphur (S) in soils. Archived samples from 139 basal soil monitoring plots (BSMS) sampled in 1995 and 2013, samples from eleven long-term field trials sampled in 1981 and 2017, 1167 soil samples from the areas vulnerable to S losses and 720 samples from the non-vulnerable areas sampled in 2010 were chosen for the experiments. Mehlich 3 clearly showed a statistically highly significant decrease in the soil S content caused by reduction of SO2 emissions in the long-term field experiments from 33 mg/kg in 1981 to 8 mg/kg in 2017 for the median of the untreated controls. Similar results were obtained for BSMS samples, where an average decrease from 26 mg/kg in 1995 to 17 mg/kg in 2013 was found. Mehlich 3 also showed that more than 52% of samples from the areas vulnerable to S losses were in a very low content category in contrast to only 3% of soils from the other areas. Mehlich 3 clearly proved the capacity to distinguish changes in the content of soil S in all studied cases. |
Detection methods for Mycobacterium avium subsp paratuberculosis in milk and milk products: a reviewI. Slana, F. Paolicchi, B. Janstova, P. Navratilova, I. PavlikVet Med - Czech, 2008, 53(6):283-306 | DOI: 10.17221/1859-VETMED Mycobacterium avium subsp. paratuberculosis (MAP) is the etiologic agent of paratuberculosis, a disease with considerable economic impact, principally on dairy cattle herds. Animals with paratuberculosis shed viable MAP especially in their milk, faeces and semen. MAP may have a role in the development of Crohn's disease in humans via the consumption of contaminated milk and milk products. The current methods of milk pasteurization are not sufficient to kill all MAP cells present in milk and MAP has been cultured from raw or pasteurized milk and isolated from cheese. The purpose of the present study was to review the different methods used for detection of MAP in milk and milk products. We analyze the current methods for direct or non direct identification of MAP and culture and molecular biology methods that can be applied to milk and milk products. |
Stressor factors in the transport of weaned piglets: a reviewReviewP. Roldan-Santiago, R. Martinez-Rodriguez, A. Yanez-Pizana, M.E. Trujillo-Ortega, M. Sanchez-Hernandez, E. Perez-Pedraza, D. Mota-RojasVet Med - Czech, 2013, 58(5):241-251 | DOI: 10.17221/6805-VETMED The transport of weaned piglets is considered an important stress factor since the conditions involved in shipping affect the animals' health and welfare. The principal stressor factors that piglets experience during transport include: mixing with unfamiliar animals, overcrowding, heat, cold, temperature fluctuations, vibrations, and noise. It is well known that all these factors contribute to raising the level of stress caused by the weaning process; however, the additional effects attributable to transport immediately after weaning impact the physiology, metabolism and behaviour of piglets, predisposing them to delayed growth. For this reason, animal transport must be well-planned and take into account such aspects as preparation of the piglets, choosing the best route and vehicle type, assuring adequate vehicle design and maintenance, and providing sufficient space. Also important for assuring the welfare of the piglets during transport are sufficient rest time, appropriate access to food and water, defined measures for monitoring the animals during the trip, implementing means of disease control, and establishing the steps to be followed in case of an emergency. |
Monitoring the avermectin and pyrantel resistance status of nematode parasites of horses in the Czech RepublicOriginal PaperS. Bodecek, J. Svetlikova, K. Hargitaiova, Z. Kecerova, M. MrackovaVet Med - Czech, 2018, 63(7):299-305 | DOI: 10.17221/125/2017-VETMED The avermectin and pyrantel resistance of equine parasites was monitored on four farms in the Czech Republic in 2014. The aim of the testing was to investigate the anthelmintic resistance of cyathostomins and ascarids. One hundred and eighty-six horses were included in the test, 54 of which were infected by ascarids and 174 by cyathostomins. Faecal egg count reduction tests were used to assess anthelmintic resistance. The faecal egg count reduction for ascarids was within the range of 87.9% to 100% for avermectins and 100% for pyrantel embonate. Faecal egg count reduction for cyathostomins ranged from 99% to 100% for avermectins and 89.3% to 98.2% for pyrantel embonate. |
New epiphytic yeasts able to reduce grey mold disease on applesOriginal PaperAmina KHEIREDDINE, Badiâa ESSGHAIER, Abdeljabar HEDI, Cyrine DHIEB, Najla SADFI-ZOUAOUIPlant Protect. Sci., 2018, 54(4):248-257 | DOI: 10.17221/103/2017-PPS Botrytis cinerea, the causal agent of grey mould, is a predominant agent causing extensive postharvest and quality losses of apples in Tunisia and worldwide. Efforts to manage this disease have met with limited success. For this reason, the use of microorganism preparations to control fungal diseases as an alternative to fungicides became an urgent need. From a total of 60 epiphytic yeasts, 10 were assessed in vitro against B. cinerea and selected isolates showing antagonism were evaluated for their ability to suppress the grey mould in vivo. On Petri plates, the most promising strains (three strains of Aureobasidium pullulans, one Cryptococcus flavescens, and one Citeromyces matritensis) showed a zone of inhibition against the pathogen fungus not exceeding 10 mm. In vivo, these isolates showed a remarkable antifungal activity since they significantly reduced disease severity on apples from 63% to 95% compared to the control. In conclusion, the work has demonstrated that the three strains, L7 of Aureobasidium pullulans, L2 of Citeromyces matritensis, and L10 of Cryptococcus flavescens, were highly effective and can be used as potential biocontrol agents in controlling the post-harvest decay of apples caused by B. cinerea. |
Influence of fertilization on Miscanthus × giganteus (Greef et Deu) yield and biomass traits in three experiments in SerbiaOriginal PaperGordana DRAZIC, Jelena MILOVANOVIC, Jela IKANOVIC, Ivana PETRICPlant Soil Environ., 2017, 63(4):189-193 | DOI: 10.17221/156/2017-PSE Miscanthus × giganteus (Greef et Deu) is an agro-energy crop of the second generation cultivated in purpose to obtain annually renewable bio-fuel produced from the aboveground biomass. Cultivation is preferred on marginal lands to avoid occupation of arable lands. Influence of fertilization and soil type Gleysol, Planosol and Technosol (open pit coal mine overburden) on yield and biomass traits of miscanthus were investigated during five years' field experiment. Among biometric characteristics: stem height, length and width of leaves, the number of leaves (dry and green) per stem and number of stems per rhizome, only the last one has a strong positive correlation with yield. Fertilization increased yield during fourth and fifth year of development on Gleysol and Technosol. The highest yield on Gleysol was 23.12 t/ha in 2014, on Planosol 10.16 t/ha, and 4.77 t/ha in 2015 on Technosol. The yield of miscanthus, beside fertilization, depends on weather conditions and weeds. Cultivation of miscanthus is possible on marginal soils with minimum application of agricultural measures only in the year of establishment. Gleysol is a type of soil that can be recommended for miscanthus cultivation. |
Ivy pelargonium response to media containing sewage sludge and potato pulpOriginal PaperAgnieszka ZAWADZIŃSKA, Piotr SALACHNAPlant Soil Environ., 2018, 64(4):180-185 | DOI: 10.17221/10/2018-PSE In a two-year pot experiment, the effect of five growing media on the growth, flowering, decorative value of Pelargonium peltatum cv. Maxime as well as on their uptake of the nutrients and heavy metals were studied. The media were prepared from four composts (made from: sewage sludge 70% or 35%, potato pulp 35%, straw 30% or sawdust 30%) and peat in 1:1, V:V ratio. In the 1st year of research 7-month-old composts and in the 2nd year 18-month-old composts were used. Plants cultivated in 7-month-old composts showed better growth-related parameters, created more inflorescences and were more decorative than those cultivated in 18-month-old ones. The medium with compost consisting of 70% sewage sludge and 30% straw gave the best results. Composts application increased nutrients and heavy metals content in pelargonium leaves. Heavy metals content was definitely lower than the value considered toxic to plants. |
Effect of long-term mineral fertilizer application on soil enzyme activities and bacterial community compositionOriginal PaperYanling CHEN, Jintao LIU, Shutang LIUPlant Soil Environ., 2018, 64(12):571-577 | DOI: 10.17221/658/2018-PSE Soil bacteria are critical to maintain soil fertility. In this study, soil chemical properties, enzyme activities and soil bacterial community from a long-term fertilizer experiment (37 years) were analysed to elaborate the effects of long-term mineral fertilizer application on soil enzyme activities and bacterial community composition. Compared with control treatment, bacterial community richness was reduced in low nitrogen (N) fertilizer and high N fertilizer treatments and increased in high N fertilizer and phosphorus (P), high N fertilizer and potassium (K) (N2K), and high N fertilizer, P and K (N2PK) treatments. The distribution of each phylum and genera was obviously changed and the range of the dominant phyla was not affected in all fertilization treatments. Principal component analysis showed that soil bacterial community in the N2K treatment was clearly different than in the N2PK treatment. The N2PK treatment had much higher available P, total organic carbon, invertase, urease and phosphatase activities than the N2K treatment, which might change soil bacterial community composition. In conclusion, fertilization with combined application of P, K and N in appropriate proportions is an optimum approach for improving soil quality and soil bacterial community abundance in non-calcareous fluro-aquic soils in the North China Plain. |
Effective palliative treatment of recurrent soft tissue sarcoma in a dog using imatinib mesylate (Gleevec®)Case ReportG.H. Kim, J.H. KimVet Med - Czech, 2018, 63(11):532-536 | DOI: 10.17221/34/2018-VETMED A 14-year-old neutered female Yorkshire terrier presented with a rapidly growing gluteal mass. There was a history of surgical resection of a mass diagnosed as a grade two soft tissue sarcoma in the same region a year earlier. The second mass was surgically excised and histopathologically diagnosed as grade two soft tissue sarcoma. A further relapse occurred six months after the second surgery. On that occasion, the dog was treated with metronomic chemotherapy consisting of cyclophosphamide and piroxicam, which failed to adequately control the disease and the mass increased 2.5-fold in size in three weeks. Imatinib treatment was started, after which there was a 62% reduction in the size of the mass. The patient has remained in partial remission for five months. To the authors' knowledge, this is the first report on the use of imatinib to treat canine soft tissue sarcoma. Imatinib might be a useful treatment for soft tissue sarcoma that recurs after surgical resection. |
Pathogenicity of Beauveria bassiana strain 202 against sap-sucking insect pestsOriginal PaperGhulam Ali Bugti, Wang Bin, Cao Na, Lin Hua FengPlant Protect. Sci., 2018, 54(2):111-117 | DOI: 10.17221/45/2017-PPS An experimental trial was conducted to determine the pathogenicity of Beauveria bassiana strain 202 (Bb-202) against multiple targeted sucking insect species that are serious pests of crops and ornamental plants. The insect species, Myzus persicae Sulzer (Hemiptera: Aphididae), Jacobiasca formosana Paoli (Hemiptera: Cicadellidae), Bemisia tabaci Gennadius (Hemiptera: Aleyrodidae), and Stephanitis nashi (Hemiptera: Tingidae) were exposed to conidia of B. bassiana at rates of 1.0 × 102, 3.5 × 103, 5 × 104, and 6.75 × 105 conidia/mm2 to determine the pathogenicity of B. bassiana. The fungal strain Bb-202 showed the highest pathogenicity to M. persicae and 100% corrected mortality observed in the treatments over 1.0 × 102 conidia/mm2, followed by the J. formosana with the final corrected mortality of 86.6, 94.4, and 97.4% after 10 days of fungal inoculation with 3.5 × 103, 5 × 104, and 6.75 × 105 conidia/mm2, respectively. The strain Bb-202 also showed good pathogenicity to B. tabaci and corrected mortalities of 77.9 and 81.1% were recorded when exposed to 5 × 104 and 6.75 × 105 conidia/mm2. Relatively weak pathogenicity was observed in S. nashi, in which the highest corrected mortality of 63.7% occurred at 6.75 × 105 conidia/mm2. Accordingly, the LC50 and LT50 values of concentrations 1 × 105, 1 × 106, 1 × 107, and 1 × 108 conidia/ml were calculated for M. persicae, J. formosana, B. tabaci, and S. nashi that were determined as 6.7 × 104, 1.3 × 106, 3.6 × 106, and 1.2 × 107 conidia/ml and LT50 was observed as 5.2~8.24, 5.1~6.6, 7.2~9.0, and 7.9~9.6 in days, respectively. |
A global meat tax: from big data to a double dividendOriginal PaperJarka CHLOUPKOVA, Gert Tinggaard SVENDSEN, Tomas ZDECHOVSKYAgric. Econ. - Czech, 2018, 64(6):256-264 | DOI: 10.17221/270/2016-AGRICECON The Food and Agriculture Organization of the United Nations (FAO) emphasizes the right of everyone to have access to safe, sufficient and nutritious food in its Rome Declaration. This article suggests how this noble FAO goal can be achieved. We suggest that a first step could be the introduction of a global meat tax, where the size of the negative externalities from meat production could be calculated based on foresight and big data. Applying the tool of a global meat tax will lead to a "double dividend" as negative externalities are reduced and at the same time huge tax revenues will be generated which could be used to make further steps in the direction of achieving the stated FAO goal in the Rome Declaration. |
Phytochemical changes in mango fruit in response to Alternaria alternata infectionFood Analysis, Food Quality and NutritionJiao LI, Liangang MAO, Yanning ZHANG, Lan ZHANG, Hongyun JIANGCzech J. Food Sci., 2018, 36(3):227-232 | DOI: 10.17221/328/2017-CJFS Changes in mango fruit quality, malondialdehyde content, and enzymatic activities in response to pathogen Alternaria alternata infection were studied. A. alternata significantly affected the appearance of mango fruit at 5 and 7 days after treatment (DAT). The quality of pathogen-infected fruit first showed a significant decrease in titratable acidity and vitamin C content and a significant increase in pH since 3 DAT. The malondialdehyde content was higher than that in the untreated controls at 3 and 7 DAT. The enzyme activities of ascorbate peroxidase and polyphenol oxidase showed significant increases since 3 DAT. Significant increases in l-phenylalanine ammonia-lyase and superoxide dismutase activities were observed at 7 DAT. These results indicate that A. alternata infection first significantly affects some biochemical constituents and enzyme activities in mango fruit since 3 DAT and that there was no significant effect on appearance until 5 DAT. |
Characterisation of methicillin-susceptible Staphylococcus pseudintermedius isolates from canine infections and determination of virulence factors using multiplex PCROriginal PaperO. Melter, P. Svec, J. Tkadlec, J. Doskar, H. Kinska, R. PantucekVet Med - Czech, 2017, 62(2):81-89 | DOI: 10.17221/105/2016-VETMED Staphylococcus pseudintermedius is a genuine opportunistic pathogen of the skin, especially in canids. However, characterisation of virulence, antimicrobial resistance and genotypic variability in methicillin-susceptible S. pseudintermedius isolates has not been fully explored. In this study, coagulase-positive staphylococcal isolates collected from dogs of various breeds and ages suffering from dermatitis (n = 70), pyoderma (n = 7), and otitis (n = 7), from districts of Prague (Czech Republic) and surrounding areas, were characterised using matrix-assisted laser desorption/ionisation time-of-flight mass spectrometry, and repetitive sequence-based PCR fingerprinting. Susceptibility to antimicrobial agents was determined, virulence factor genes for leukocidin (lukSF-I), exfoliatins (exi, expB, and siet), enterotoxin C (seccanine) and enterotoxin-related genes (se-int and sel) were detected using multiplex PCR and the genotypes of S. pseudintermedius isolates were determined using SmaI macrorestriction analysis. The majority of the staphylococcal isolates (n = 84) were identified as S. pseudintermedius (n = 79) and all of them were susceptible to methicillin/oxacillin (MSSP). About half of the strains (n = 41) were resistant to macrolide-lincosamide-streptogramin B antimicrobial agents and resistance was mediated in all but one of the strains by the erm(B) gene. The genes for lukSF-I, siet, se-int, and sel were detected in the majority of the MSSP strains (96.2%, 100%, 100%, and 73.4%, respectively). Investigated canine S. pseudintermedius isolates were highly heterogeneous, which prevented the correlation of any specific lineage to a particular infection, dog breed, or region of origin. |
Surgical treatment of a thoracic oesophageal duplication cyst causing recurrent dysphagia in an adult dogCase ReportA. Foglia, S. Del Magno, M. Pietra, V. Cola, M. Joechler, M. Morini, L. PisoniVet Med - Czech, 2018, 63(4):175-180 | DOI: 10.17221/113/2017-VETMED A 7-year-old intact male Rottweiler dog was evaluated for recurrent dysphagia and regurgitation. Physical examination was unremarkable and routine blood works were within normal limits. Computed tomography revealed a defined lesion in the caudal mediastinum arising from the oesophagus. The lesion was excised using intercostal thoracotomy and the histological diagnosis was oesophageal duplication cyst. The dog recovered uneventfully and at a 3-year follow-up no clinical signs were reported. Although extremely rare, oesophageal duplication cysts should be considered in the differential diagnosis in cases of chronic regurgitation and dysphagia associated with evidence of an oesophageal lesion. |
New late ripening apricot genotypes from a multipurpose apricot breeding programme in TurkeyShort CommunicationJoanna Marie CROSS, Firat Ege KARAAT, Feyza İNCEOĞLU, Zehra Tuğba MURATHAN, Bayram Murat ASMACzech J. Genet. Plant Breed., 2018, 54(1):34-38 | DOI: 10.17221/159/2016-CJGPB The harvest season of apricots is short and fruit cannot be protected in cold stores for a long time. For those reasons, apricot production and consumption are lower than in other fruit species. This study was conducted for the purpose of breeding new late ripening apricot varieties. To this aim, a total of 3718 hybrid genotypes of apricots were obtained from 42 crosses. Phenological, pomological and yield analyses were performed and variations of fruit development period, fruit size, polarimetric dry matter (Brix), total acidity, yield and other traits were determined. Two years of results for important traits are given for 12 promising genotypes. Fruit development period varied between 148 and 167 days, fruit weight 25.2 and 41.2 g, Brix 16.3 and 22.6% and total acidity 0.56 and 1.25%. |
Trichoderma atroviride enhances phenolic synthesis and cucumber protection against Rhizoctonia solaniOriginal PaperJustyna Nawrocka, Magdalena Szczech, Urszula MałolepszaPlant Protect. Sci., 2018, 54(1):17-23 | DOI: 10.17221/126/2016-PPS The treatment of cucumber plants with Trichoderma atroviride TRS25 (TRS25) provided protection against infection by Rhizoctonia solani. In plants inoculated with the pathogen, nontreated with Trichoderma, disease symptoms were observed on the roots, shoots, and leaves while in plants treated with TRS25 the spread of the disease was limited. The induction of systemic defence response in cucumber against R. solani infection seemed to be strongly related to the enhanced synthesis of phenolic compounds in plants. HPLC analysis indicated remarkable increases in the concentrations of 23 phenolics belonging to hydroxybenzoic acids, cinnamic acids, catechins, flavonols, flavons, and flavanons in the plants without systemic disease symptoms. We suggest that the accumulation of phenolic acids, flavonoids and de novo synthesis of catechins may strongly contribute to cucumber protection against R. solani. |
Warming impacts on carbon, nitrogen and phosphorus distribution in soil water-stable aggregatesOriginal PaperSong GUAN, Na AN, Jinhua LIU, Ning ZONG, Yongtao HE, Peili SHI, Jinjing ZHANG, Nianpeng HEPlant Soil Environ., 2018, 64(2):64-69 | DOI: 10.17221/715/2017-PSE A five-year (2010-2015) field experiment was conducted to investigate warming impacts on organic carbon (OC), total nitrogen (TN) and total phosphorus (TP) contents and their ratios in bulk soil and soil water-stable aggregates in an alpine meadow of the Tibetan Plateau. Compared with unwarmed control, warming had no significant effects on OC, TN and TP contents and their ratios in bulk soil. The contents of OC, TN and TP associated with macroaggregates and microaggregates decreased, whereas those associated with silt + clay fractions significantly increased. The C:N and C:P ratios in macro- and microaggregates and silt + clay fractions decreased, with significant differences for C:P ratio in microaggregates and C:N and C:P ratios in silt + clay fractions. The results indicated that C, N and P were protected chemically in silt- and clay-size fractions under warming, which offset the loss of C, N and P protected physically by macro- and microaggregates. Both physically and chemically protected C decomposition proceeded relatively more rapidly or accumulated relatively more slowly than did N and P. Our results suggest that C, N and P distributions within soil aggregate size fractions influence their net changes in bulk soil under future climate change scenarios. |
Plant composition, herbage yield, and nitrogen objectives in Arrhenatherion grasslands affected by cattle slurry applicationOriginal PaperRenata DUFFKOVÁ, Jakub BROMPlant Soil Environ., 2018, 64(6):268-275 | DOI: 10.17221/178/2018-PSE Cattle slurry is commonly used to fertilize grasslands, so its impact on plant composition and herbage properties is important. Cattle slurry at annual rates of 60 (S1), 120 (S2), 180 (S3), and 240 kg nitrogen (N)/ha (S4) was applied to Arrhenatherion grasslands in moderately wet (WS), slopy (SS), and moderately dry (DS) sites cut three times a year over six years, to assess its effects on plant functional types, the Ellenberg N indicator value (Ellenberg N), herbage dry matter (DM) yield, herbage N content and offtake, N nutrition index (NNI), and N use efficiency (NUE). The site-specific changes in an increase in graminoid cover, Ellenberg N, herbage DM yield and N offtake, and NNI along with slurry application rates revealed, while cover of legumes, short forbs, and NUE decreased. In more productive sites (WS and SS), slurry application in the amount of 180 kg N/ha could be suggested as a slurry dose ensuring beneficial agronomic objectives. However, nature conservation requirements via maintaining plant biodiversity were not met. On the contrary, short-term slurry application up to 120 kg N/ha ensured on permeable DS not only sufficient agronomic objectives, but also plant biodiversity conservation requirements. |
Nonlinear models of Brazilian sheep in adjustment of growth curvesOriginal PaperClaudia Cristina Paro de Paz, Guilherme Costa Venturini, Enio Contini, Ricardo Lopes Dias da Costa, Luara Paula Lameirinha, Celia Raquel QuirinoCzech J. Anim. Sci., 2018, 63(8):331-338 | DOI: 10.17221/87/2017-CJAS Growth curves of the Morada Nova sheep males and females were described using nonlinear models and the relationships between body weight and thoracic circumference were evaluated. Altogether 1516 repeated measures of body weight and thoracic circumference of the Morada Nova sheep (668 males and 848 females) taken since birth till 730 days of age were used. The Brody, Richards, von Bertalanffy, Gompertz, and Logistic models have been tested. The Fisher's test (F) was used to verify the differences (P < 0.05) in growth curves between males and females. The Gompertz model presented a significant difference (P < 0.001) for growth curve parameters between males (asymptotic weight (A) = 40.5 kg and maturing rate (k) = 0.0043 kg/day) and females (A = 36.44 kg and k = 0.0028 kg/day). The relationships between body weight and thoracic circumference presented R2 above 0.7 and a high significance (P < 0.0001) for all categories, showing that the thoracic circumference may be a good indicator of body weight. In addition, a significant effect (P < 0.05) of the relationship between thoracic circumference and prediction of animal's body weight was verified using the models of linear, quadratic, and cubic regression. Among the models studied, the Gompertz model presented the best fit and biological interpretation. Furthermore, the Gompertz model indicated the need to separate animals by sex in order to properly meet nutritional requirements and determine adequate slaughter age. Thoracic circumference can be used to predict animal body weight with a high accuracy. |
Kitchen cooking by electroporationOriginal PaperFrantiąek Kumhála, Jakub Lev, Pavel Kouřím, Jiří BlahovecRes. Agr. Eng., 2022, 68(2):102-107 | DOI: 10.17221/96/2021-RAE Recently, modern non-heating-based food processing alternatives have emerged. The pulsed electric field (PEF) technology is an example, which does not require high temperatures and, in principle, preserves both the nutritional and functional characteristics of the food while possibly improving the taste. Nevertheless, using this technology in kitchen conditions is still a challenge. Thus, the main aim of this work was the development of a kitchen cooking device that uses pure pulse electroporation (without thermal effects). A device powered by a common electrical network was designed. The voltage applied to the electrodes is approximately 150 V. At a food thickness of 3 mm, an intensity of 500 V.cm-1 was achieved, which was sufficient for the electroporation of typical vegetables. Depending on the specific food being treated, the device repeats the pulses until the required degree of the PEF treatment is reached. Preparing a larger amount of food at one time would require great instant power from the device. In order to load the device with less current, the large working area of the electrodes was divided into nine segments. The food is gradually prepared segment by segment. The function of the device is controlled via an electronic programmable control unit. The electroporation of the processed material was achieved with a functional prototype of the designed device, but with some limitations that have to be respected in further development. |
Effect of some bioproducts on the growth, yield and fruit quality of apple treesOriginal PaperWalid Fediala Abd El-Gleel Mosa, Lidia Sas Paszt, Mateusz Fr±c, Paweł Trzciński, Michał Przybył, Waldemar Treder, Krzysztof KlamkowskiHort. Sci. (Prague), 2018, 45(3):111-118 | DOI: 10.17221/75/2017-HORTSCI hese experiments began with the planting of maiden apple trees of cv. 'Topaz' in 2011. In springtime in 2012-2016, chemical fertilisation (NPK) and various natural bioproducts, namely Fertigo, Micosat, Humus UP, Humus Active + Aktywit PM, Aktywit PM, BioFeed Quality, BioFeed Amin, Vinassa, Florovit Natura and Florovit Eko were applied to the apple trees alone or enriched with Pantoea sp., Pseudomonas fluorescens, Klebsiella oxytoca and Rhizobium bacterial species. Growth, yield and fruit quality parameters were then evaluated. Our results reveal that the trunk cross-sectional area was greatly increased by the addition of the beneficial bacteria to Humus UP, Yeast, Vinassa and Micosat, as compared to NPK chemical fertilisation. Yeast, Vinassa, Micosat, Humus UP and BioFeed Amin enriched with the beneficial bacteria significantly increased fruit weight in kg and the number of fruits compared to the NPK control in 2015 and 2016. |
