Abstract:
To investigate the inherent characteristics of the pathogenic Yersinia enterocolitica. Polymerase chain reaction (PCR),analysis of DNA sequence,randomly amplified polymorphic DNA (RAPD) were used to study the pathogenic and nonpathogenic 10 strains of Yersinia enterocolitica. The Pathogenic Yersinia enterocolitica of serotyps 0∶3?0∶9 and 0∶5,27 were confirmed containing pathogenic gene of adherent invasion locus(ail) and their DNA fingerprints were much more similar,and it was also found that the serotype 0∶22 contained ail gene whose fingerprints was partly similar with the pathogenic ones in molecular structure. The pathogenic Yersinia enterocolitica strains were similar in the inherent and polymorphic. The serotype 0∶22 may have relativly evaluated association with pathogenic Yersinia enterocolitica, which is possible that it got potentially pathogenicity.
