In this study, pathogenic strains of Y. enterocolitica were identified by microbiological and PCR methods. The samples were collected from pigs, cattle, poultry, and slaughter houses. Three common techniques were used to isolate Y. enterocolitica from the samples – ITC, PSB, and direct on the CIN. Primers A1/A2, Y1/Y2, and rfbC 1/rfbC 2 were used for the specific detection of the pathogenic strains of Y. enterocolitica. Traditional microbiological methods were found to be insufficient for the specific identification of the Y. enterocolitica pathogen. In comparison with PCR which was able to detect 149 strains, the biochemical test could detect only 138 species. These results show that the use of biochemical methods of cultivation did not allow the identification of all Y. enterocolitica pathogens. In total, 149 strains of pathogenic Y. enterocolitica were examined of which 120 were from pigs, 19 from poultry, 8 were cattle strains, and 2 came from the environments of slaughterhouses.
