biotypes, serotypes and lysotypes of 38 yersinia isolated from 48 water samples were studied. these strains belonged to y.enterocolitica, y.frederiksenii, y.kristensenii and y. intermedia. except 23.7% of non-serotypable strains, ten different serotypes were isolated of which 0:6 and 0:10 kl were the most frequent. the serotypes 0:3, 0:8, 0:9 responsible for almost all registered cases of yersi...

The species Yersinia intermedia is a member of the genus Yersinia which belongs to the Enterobacteriaceae family. This species is divided into eight biotypes, according to Brenner's biotyping scheme. This scheme relies on five tests (utilization of Simmons citrate and acid production from d-melibiose, d-raffinose, alpha-methyl-d-glucoside [alphaMG], and l-rhamnose). The collection of the French...

Infections due to biochemically typical Yersinia enterocolitica usually present as gastroenteritis, mesenteric lymphadenitis, terminal ileitis, and septicemia often with visceral abscesses. In these instances, the isolates have been biochemically typical and of well-established serotypes, namely 0:3 or 0:9 and, in the United States, 0:5 or 0:8. The recovery, recognition, and significance of bio...

Biochemical and serological data are presented for 35 isolates of Yersinia enterocolitica from raw goat's milk produced in New South Wales, Australia. Strains resembled biotype I or 2, but the majority (25 of 35) fermented rhamnose and some showed other atypical reactions.

Thirteen atypical Yersinia enterocolitica isolates, all fermenting rhamnose, raffinose, and melibiose and utilizing sodium citrate within 24 to 48 h at 22 degrees C (Y.e.rh+), were examined biochemically-serologically, and by gas-liquid chromatography. These data, as well as cultural, biochemical, and antibiotic susceptibility data gathered from two previous studies involving (i) these same aty...

AIMS To determine the species, bio-sero-phagetypes, antimicrobial drug resistance and also the pathogenic potential of 144 strains of Yersinia spp. isolated from water sources and sewage in Brazil. METHODS AND RESULTS The 144 Yersinia strains were characterized biochemically, serologically and had their antibiotic resistance and phenotypic virulence markers determined by microbiological and s...

materials and methods: a total of 285 commercial and traditional dairy products as well as 267 pasteurized and raw milk samples were collected during one year. the samples were studied by culturing and the positive-culture samples were investigated using pcr techniques. results: the results of culture showed that 52 (9.42%) and 28 (5.07%) of the total 552 milk and dairy samples were positive fo...

background: brucellosis is still considered as one of the major zoonosis afflicting syrian health and economy. this disease is caused by members of the genus brucella which are gram-negative bacteria living facultatively within mammalian cells during infection. objectives: in this paper, a strategy was developed to introduce a new generation of binders called nanobodies (nbs) in our combat aga...

Plague is a flea-borne zoonosis caused by the bacterium Yersinia pestis. Y. pestis mutants lacking the yersiniabactin (Ybt) siderophore-based iron transport system are avirulent when inoculated intradermally but fully virulent when inoculated intravenously in mice. Presumably, Ybt is required to provide sufficient iron at the peripheral injection site, suggesting that Ybt would be an essential ...
