Antibiotic Resistance and Β-lactamases of Yersinia Enterocolitica Isolated from Pigs in Poland
Sixty-two isolates of pig-derived Yersinia enterocolitica belonging to 1A and 4 biotypes and non-typeable isolates were subjected to antimicrobial resistance testing by the disc diffusion method. The presence of β-lactamase A (Bla-A) and B (Bla-B) was detected by the double disc diffusion test, and the β-lactamase genes blaA and blaB in these isolates were detected by PCR. The isolates were res...

متن کاملTemperature-modulated immunogenicity to Yersinia pestis from Yersinia enterocolitica O3.
The ability of Yersinia enterocolitica O3, grown at 25 degrees C, to promote cross-immunity to Y. pestis was lost after repeated subcultures at 37 degrees C, which selected for bacterial populations having lower in vivo survival. Subculturing Y. enterocolitica O3 from 37 to 25 degrees C restored the cross-immunogenicity although the in vivo survival remained low.
متن کاملDirect isolation of Yersinia enterocolitica and Yersinia pseudotuberculosis from meat.
Studies were done to determine the usefulness of dilute alkali (KOH) treatment of meat samples for direct isolation of Yersinia enterocolitica and Yersinia pseudotuberculosis, without enrichment. Virulent Y. enterocolitica and Y. pseudotuberculosis in pork contaminated with 10(2), 10(3), and 10(4) cells per g survived the direct KOH treatment and were never recovered by using KOH postenrichment...
متن کاملIsolation of Yersinia enterocolitica from swine.
Data pertaining to 20 strains of Yensinia enterocolitica isolated from the cecal content of swine slaughtered at Toronto Abattoirs are presented. Fifteen of 20 cultures belonged to the two predominant human serotypes in Ontario (i.e., serotype O:3 and O:5,27.) Seven cultures of Y. enterocolitica O:3 belonged to the "Canadian" human phage type 9b. These findings are further proof that swine are ...
