This research was aimed at investigating the temporal and spatial pattern, sex, age, breed wise distribution of leptospirosis in Tamil Nadu. A seroreactivity of 28.2% was noticed among cattle in seven agro-climatic zones. The temporal trend of leptospirosis recorded during the post-monsoon season (30.5%) was significant when compared to the pre-monsoon season (25.8%). The spatial distribution revealed a high proportion of leptospirosis (31.2%) in the North East zone in comparison with the other zones. The serogroups Australis (37.9%), Hebdomadis (30.6%), Hardjo (29.9%), Javanica (28.1%) and Pomona (19.7%) were predominant in all the agro-climatic zones. The observation of 44.2% seroreactivity in buffaloes is most probably associated with the wallowing behaviour. A high seroreactivity of 31.1% in Holstein Friesian than that compared with the native breed discloses a breed susceptibility. A seroreactivity of 30.2% in animals aged above three years shows an age-related susceptibility, but there was no significant difference between the sexes. The seroreactivity among the animals in an organised farm (33.8%) is higher than in individually reared animals (25.5%) indicating the impact of the rearing system. The three Leptospira strains isolated were identified as the Leptospira interrogans serogroup Australis, Canicola and Sejroe. This study depicted the epidemiology of leptospirosis in cattle and emphasises the need of leptospirosis to be included in cattle health surveillance programmes.

Vitamin B12 promotes haematopoiesis. The aims of this study were: 1) to compare the values of the haematological variables and the concentration of vitamin B12 in pre- or post-weaned veal calves and 2) to identify the possible association between the values of the haematological variables and the concentration of B12 in the blood of veal calves. Blood was collected on the same day from 31 pre-weaned and 31 weaned calves of the Limousine breed from the same farm. The complete blood count, including the blood cell morphology evaluation, was performed and the serum B12, total protein and albumin concentrations were determined. The serum concentration of vitamin B12, the haematocrit (HCT), the haemoglobin concentration (HGB), the platelet count and the lymphocyte count were significantly higher in the weaned calves. A very strong positive correlation was found between the concentration of the vitamin B12 and HCT and HGB before weaning, while these correlations were moderately positive following weaning and in the total population tested as well. The observed variation in the blood cell count and morphology, such as poikilocytosis and the presence of macrocytes and hypersegmented neutrophils, along with the age of the animal seem to be related to the vitamin B12 concentration.

The study investigated alterations in the morphology and morphometry of the testes of broilers in response to GC and dexamethasone (DEX). Male day-old chicks were randomly divided into a control group and three experimental groups (E1, E2, and E3). The control group was fed a commercial broiler ration. The experimental groups were fed a commercial broiler ration containing GC (i.e. DEX 3, 5, and 7 mg/kg, respectively). The testes were collected and stained with haematoxylin and eosin to count the number of testicular seminiferous tubules. An increase in the seminiferous tubule count was initially seen, which declined as both the age of the broilers and the dose of DEX increased. Morphometric measurements, i.e., the testicular capsule thickness, seminiferous tubule diameter, and seminiferous epithelium height, were performed. The initial thickening of the testicular capsule was evident. There was a depletion of the interstitial (Leydig) cell population in the experimental groups with the age and increased with the dose advancement. The diameter of the seminiferous tubules and testicular capsule thickness remained upregulated in the treatment groups with the increased dose of DEX. The initial height of the seminiferous epithelium increased in the experimental groups of broilers. The study suggests that DEX greatly alters the morphological architecture of broiler testes; as a result, it could be said that DEX has the effect on the infertility of the broiler by affecting the morphology as well as the functionality of the testes.

The aim of this study was to assess the safety of short-term exposure to sodium chloride for the common carp (Cyprinus carpio). In our experiment, fish were placed into a sodium chloride bath (c = 30 g l-1; T = 30 min; t = 20 °C) and the effects of the treatment were assessed immediately after the bath (T0) and 24, 48 and 240 h later (T24, T48 and T240, respectively), with non-treated fish serving as control groups. Though significant differences compared to the controls were observed in the treated fish sampled at T0, T24 and T48, these effects were only temporary and all the affected parameters (i.e., haemoglobin, haematocrit, plasmatic lactate, cholesterol, alanine aminotransferase, albumin, phosphorus and ceruloplasmin) had completely recovered within 10 days of exposure, suggesting that the treatment of carp with a sodium chloride bath represents a safe approach suitable for therapy of parasitic infections.

There was no history of trauma. On ultrasonography, the lesion had a cystic character filled with anechoic fluid and hyperechoic sedimenting debris. The computed tomography (CT) and CT-dacryocystography showed a cystic lesion protruding from the lacrimal sac fossa and occupying a defect in the orbital plate and an ethmoidal ectoturbinate surrounded by a bony structure with an intact nasolacrimal system. The dog underwent the surgical resection of the cyst and its fluid content was aspirated. Ethmoid mucocele was diagnosed based on the CT, cytologic examination, bacterial culture and histopathologic findings. This case describes the imaging characteristics of an ethmoid mucocele and highlights the importance of CT and CT-dacryocystography in dogs with ventromedial canthus swelling that had poor response to medical treatment.

The dog presented with several dry, tightly adhering scales showing a multi-focal appearance. The histology revealed severe orthokeratotic hyperkeratosis and hyperplasia with an irregular granular layer without epidermolysis. Non-epidermolytic ichthyosis (NI) has strong breed predilection in dogs, and its morphological features vary by breed while the microscopic changes are similar. It is likely to be the first reported case of congenital ichthyosis in a Maltese dog showing a different morphological appearance compared to other breeds with a higher prevalence of NI.
