Abstract:We investigated the distribution of Yersinia enterocolitica in Henan Province. We collected 6 057 samples of stool specimen from diarrhea patients and different domestic animals between 2011 and 2013, as well as flies and the daub specimens of raw and cooked meat products. The bacteria were isolated by cold enrichment method, analyzed by the systematic biochemistery to determine the serotypes and bio-types, and tested the virulence genes by PCR method. As a result, 288 strains of Yersinia enterocolitica were detected in 6 057 specimens and the detection rate was 4.75%. The dominant epidemic serotypes of the Yersinia enterocolitica were O∶8 and O∶5, type 1A was the dominant bio-type. The O∶3 type most have pathogenic and primary pathogenic strains were isolated from swine. In brief, the distribution of the host of Yersinia enterocolitica was widespread, while swine was the dominant animal host of athogenic strains.
