Abstract：In order to survey the germ-carrying of Yersinia enterocolitica in diarrhea patients and host animals in Henan Province, we analyze the serological distribution and virulence gene situation of Yersinia enterocolitica and explore the causes of disease. The specimens in Henan surveillance sites from 2007 to 2010 were identified preliminarily and then they were identified finally in Chinese Center for Disease Control and Prevention. A part of the strains were serotyped and detected for virulence gene of ail, ystA, ystB, yadA, verF, and rfbC. As a result, 273 strains of Yersinia enterocolitica were detected in 8 561 specimens in Henan Province from 2007 to 2010 and the detection rate was 3.19%. There were statistical differences among detection rates in different years. In all the serotypes, the highest proportion was O:5 (31.63%), following by O:8 (17.35%) and O:3 (11.22%), whereas O:9 was not detected. The most serotypes were detected in pigs (9 types) and humans, mainly containing O:3, O:8 and O:10. Pathogenic strains were detected in patients, pigs, cattle and dogs. In brief, Yersinia enterocolitica existed in humans and many kinds of animals in Henan Province. The humans’ serotypes there were in accord with the humans’ serotypes in the whole country. In Henan Province, the important animal hosts were pigs, cattle and dogs, and they may play an important role in humans’ infection.
