Abstract:
OBJECTIVETo study the distribution of Yersinia enterocolitica and its virulence factors in Nantong, Jiangsu.
METHODSYersinia strains were isolated from livestock and poultry. Conventional PCR was used to detect the virulence factors of all strains and strain 0:8 was analyzed by pulsed-field gel electrophoresis(PFGE).
RESULTSThe 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 O:8 strains isolated from China while the serotypes of Yersinia enterocolitica O:3 and O:9 which were the main epidemic strains in China, were not found in this area.
CONCLUSIONThe pathogenic Yersinia enterocolitis O:3 and O:9 were not found in Nantong,Jiangsu province.
