Yersinia intermedia: temperature-dependent bacteriocin production.
Yersinia enterocolitica and related Yersinia species share many temperature-dependent biological attributes. The present report documents temperature-dependent production of a bacteriocin-like substance only among Yersinia strains which ferment L-rhamnose, raffinose, and melibiose and which have been tentatively designed Y. intermedia. When tested by the "lawn-spotting" technique at 25 and 37 d...
متن کاملIdentification and characterization of Yersinia intermedia isolated from human feces.
Since May 1983, our laboratory has, upon request, cultured stools for Yersinia spp. by using direct plating on cefsulodin-irgasan-novobiocin agar and a 3-week cold enrichment procedure. We isolated bacteria identified as Y. intermedia from six adult patients. All isolates were recovered only by the cold enrichment procedure and misidentified as Y. enterocolitica by the API 20E system (Analytab ...
متن کاملPurification and partial characterization of a bacteriocin from Serratia marcescens.
Bacteriocin JF246 has been purified from mitomycin C-induced Serratia marcescens cells by salt extraction, ammonium sulfate fractionation, and chromatography on QAE-Sephadex and SP-Sephadex. The purified material is homogeneous on polyacrylamide gel electrophoresis in the presence of 2% sodium dodecyl sulfate or 6 m urea. In the absence of these agents, the bacteriocin associates into aggregate...
متن کاملDraft Genome Sequences of Yersinia frederiksenii, Yersinia intermedia, and Yersinia kristensenii Strains from Brazil
Yersinia enterocolitica-like strains are usually understudied. In this work, we reported the draft genome sequences of two Yersinia frederiksenii, two Yersinia intermedia, and two Yersinia kristensenii strains isolated from humans, animals, food, and the environment in Brazil. These draft genomes will provide better molecular characterizations of these species.
متن کاملCharacterization of atypical isolates of Yersinia intermedia and definition of two new biotypes.
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...
