Case study of Yersinia enterocolitica infection / 中国人兽共患病学报

ABSTRACT

Yersinia enterocolitica infection in humans and animals was investigated in this study to explore the source of infection .We collected samples from patients and pigs ,and then the strains were conducted to undergo serotyping ,virulence gene detection and PFGE molecular typing .Of the 150 patients samples ,3 were tested positive for Yersinia enterocolitica ,and one of them was O∶3 .Of the 222 pigs samples ,14 were tested positive for Yersinia enterocolitica ,and all of them were O∶3 .PFGE molecular typing showed that the Yersinia enterocolitica from patient and pig had high homology .Our study con-firmed that Yersinia enterocolitica from pigs could infect people and find that it could exist in the cured patient for at least two months .
