摘要：Various isolation methods of enteropathogenic Yersinia enterocolitica were used in the study presented in this paper. By the preenrichment and enrichment procedures of the material, contamination of milk with Y. enterocolitica was demonstrated in 31,5% of samples. Detection of Y. enterocolitica was carried out in the dependance of seasonal variations of samples with maximal values in March and minimal in October (1.8%). Identification of isolated, suspicious strains was performed by a modern API 10 E system (Accurate Precise Identification).
