Abstract:
To investigate the infection of Yersinia enterocolitica in Dengfeng City ,the strains were isolated from livestock and poultry .The strains were detected with biochemiological methods ,serological methods ,and virulence genes were detected with PCR .A total of 105 strains of Yersinia enterocolitica were classified from 1 285 stool samples ,the total isolation rate was 8 .17% .Among the total isolated strains ,17 strains were classified from dogs with a rate of 17 .35% and 35 strains from pigs with 13 .62% .Twelve strains were O ∶3 serotype (13 .48% ) ,12 strains were O ∶5(13 .48% ) ,and 14 strains were O ∶8 (15 .73% ) .Ail+ ,ystA+ ,yadA+ and virF+ accounted for 12 .36% ,and ystB+ accounted for 42 .70% .In conclusion ,the pigs and dogs were important animal hosts ,which may play the major role in humans'infection .
