Abstract: | Thirty-five Yersinia enterocolitica strains isolated from humans, pigs and foxes were analysed by genotyping including intergenic transcribed sequence (ITS) profiling, REP- and ERIC-PCR. ERIC-PCR revealed the presence of seven different genotypes. Amplification of the 16S-23S rDNA spacer region by ITS profiling gave similar results with nine different genotypes. REP-PCR was found to be more discriminatory for typing of Y. enterocolitica than ERIC-PCR and ITS profiling. Fifteen different DNA patterns were obtained by this technique. Based on data obtained by three methods it was found that: (i) Y. enterocolitica strains belonging to the same serotype can represent different genotypes and vice versa; (ii) isolates recovered from humans, pigs and foxes exhibit limited heterogeneity and, independent of the origin, one or two prevailing genotypes were always observed; and (iii) many human Y. enterocolitica isolates shared common genotypes with porcine isolates. |
