| Abstract: | Objective] The paper was to analyze the carrying status of high pathogenicity island(HPI) in pathogenic Escherichia coli of mink.Method] Eight strains of E. coli were isolated from dead mink, and conducted pathogenicity test of artificial infection. The carrying status of HPI(irp2, fyu A) was detected by PCR. Result] Eight strains of E. coli were pathogenic E. coli, and the carrying rate of HPI(irp2, fyu A) was 100%,positively correlated with the pathogenicity. Conclusion] The results lay a foundation for further exploring the pathogenic mechanism of E. coli.. |
