ABSTRACT
<p><b>OBJECTIVE</b>To study the distribution of Yersinia enterocolitica and its virulence factors in Nantong, Jiangsu.</p><p><b>METHODS</b>Yersinia strains were isolated from livestock and poultry. Conventional PCR was used to detect the virulence factors of all strains and strain 08 was analyzed by pulsed-field gel electrophoresis(PFGE).</p><p><b>RESULTS</b>The combined isolation rate of Yersinia enterocolitica from livestock and poultry was 31.06% and the gene distribution characters were 39.57% of them were ail-, ystA- , ystB-, yadA- , virF-; 60.43% were ail- , ystA- , ystB + , yadA- , virF- respectively. The two reference strains from America and Denmark showed similar electrophoresis patterns but were significantly different with O8 strains isolated from China while the serotypes of Yersinia enterocolitica O3 and O9 which were the main epidemic strains in China, were not found in this area.</p><p><b>CONCLUSION</b>The pathogenic Yersinia enterocolitis O3 and O9 were not found in Nantong,Jiangsu province.</p>
