Clonal dissemination of Yersinia enterocolitica strains with various susceptibilities to nalidixic acid.
Ten epidemiologically related Yersinia enterocolitica clinical isolates were studied. Six isolates were nalidixic acid resistant (MIC > 512 microg/ml), with mutations in the quinolone resistance-determining region (QRDR) of the gyrA gene, suggesting clonal dissemination of a nalidixic acid-susceptible Y. enterocolitica strain which has acquired different mutations generating resistance to nalid...
متن کاملAntigenic relationships among type strains of Yersinia enterocolitica and those of Escherichia coli, Salmonella spp., and Shigella spp.
The antigenic type strains for Yersinia enterocolitica antigens O:1 to O:34 were examined and their antigenic relationships with the type strains of Escherichia coli, Shigella spp., and Salmonella spp. were determined. Y. enterocolitica O:5,27 was antigenically identical to E. coli O97 and Y. enterocolitica O:11 was antigenically identical to E. coli O98.
متن کاملgenetic diversity among yersinia enterocolitica isolated from chicken and fish in and around coimbatore city, india.
yersinia enterocolitica is rapidly emerging worldwide as an enteric pathogen and has become a major cause of diarrhea even in developed countries. the aim of this study was to characterize and genetic diversity analysis among y. enterocolitica strains isolated from fish and chicken sources.from 44 strains, 55% (24 strains) found to be positive for y. enterocolitica by colony morphology, biochem...
متن کاملYersinia enterocolitica infection in resistant and susceptible strains of mice.
We investigated natural resistance in mice to Yersinia enterocolitica, an enteric bacterial pathogen of humans, with a view to determine host genetic factors that are important in resistance. Most mouse strains studied (C3H/HeN, BALB/c, BALB.B, DBA/2, A, Swiss, and SWR) were highly susceptible to infection (50% lethal dose [LD50], 2 X 10(2) to 6 X 10(2) Y. enterocolitica administered intravenou...
متن کاملPathogenicity of Yersinia enterocolitica serotype O3 biotype 3 strains.
It is known that Yersinia enterocolitica infection in Japan is caused mainly by serotype O3 biotype 4 strains. Recently, however, a number of serotype O3 strains which were classified biotype 3 and which ferment lactose and xylose, instead of sorbose, and give a negative Voges-Proskauer reaction have been isolated from both humans and animals. In this study, comparisons of four properties were ...
