Molecular and genetic analysis of the Bacteroides uniformis cephalosporinase gene, cblA, encoding the species-specific beta-lactamase.
The gene, cblA, encoding the species-specific, clavulanate-susceptible, endogenous cephalosporinase was cloned from Bacteroides uniformis WAL-7088. The nucleotide sequence was determined, and the cblA structural gene was found to be 891 nucleotides, with a 48% G+C composition, which is similar to that of the B. uniformis genome. The cblA open reading frame encoded an Ambler class A beta-lactama...

15 صفحه اولHeterologous expression of the Bacteroides ruminicola xylanase gene in Bacteroides fragilis and Bacteroides uniformis.
A cloned xylanase gene from the ruminal bacterium Bacteroides ruminicola 23 was transferred by conjugation into the colonic species Bacteroides fragilis and Bacteroides uniformis by using the Escherichia coli-Bacteroides shuttle vector pVAL-1. The cloned gene was expressed in both species, and xylanase specific activity in crude extracts was found to be at least 1400-fold greater than that foun...
متن کاملBeta-lactamase-producing isolates of Bacteroides species from children.
Two hundred twenty-four isolates of Bacteroides sp. were recovered from recurrently inflamed tonsils, infected peritoneal fluid, abscesses, wounds, and burns of hospitalized children. Isolates were examined for beta-lactamase production by the chromogenic cephalosporin analog 87/312 methodology. Altogether, 119 isolates were beta-lactamase producers. Of these, 53 were in the B. fragilis group, ...
