Isolation of Yersinia Enterocolitica O:9 From Cows Positive in Serological Examination of Bovine Brucellosis

Abstract

The paper presents the results of bacteriological and molecular investigations on the presence of Y. enterocolitica O:9 in the head, mammary and genital lymph nodes, spleen, liver, and uterus samples originating from 58 cows slaughtered due to the positive results of serological examinations for brucellosis. All samples were cultured for Brucella and Y. enterocolitica and examined in multiplex PCR assay (mPCR), in order to identify the universal 16S rRNA Brucella sp. marker and amplify the perosamine synthetase (
