腹泻仔貉检出携带耶尔森菌HPI毒力岛的大肠杆菌
Detection on pathogenicity islands of Yersinia enterocolitica HPI from Escherichia coli strains in diarrheic young raccoon dogs
摘要
Abstract
To understand the mechanism of E. Coli caused diarrhea in young raccoon dogs, HPI pathogenicity islands were detected to carry out Yersinia enterocolitica. Pathogenicity islands gene irp2 and fyuA were detected by PCR amplifica tion, and the virulence of E. Coli strains was determined with mice by intraperitoneal injection. E. Coli strains were isolatted from organs and feces of diarrhic young raccoon dogs, of which the serotypes were 023 and 020. In pathogenicity islands gene irp2 and fyuA, 2 serotypes of E. Coli were detected and resulted in the occurrence of serious illness and the death of experi mental mice after intraperitoneal injection in virulence detection. Diarrhea in young raccoon dogs infected with E. Coli and carry ing pathogenicity islands gene irp2 and fyuA of Yersinia enterocolitica HPI, will bring potential threats to the health of young raccoon dogs.关键词
