Cephalosporinase activity in Bacteroides fragilis.
Cephalosporinase activity was demonstrated in all of 10 strains of Bacteroides fragilis investigated. Low rates of hydrolysis of cephalosporins (0.25 to 3.5 mumol of cephaloridine per h per 10(9) cells) were found, but no activity against penicillin substrates was detected. In two strains the cephalosporinase activity was increased 40-and 80-fold by growing cells in the presence of penicillin. ...
متن کاملNutritional features of Bacteroides fragilis subsp. fragilis.
Studies of three reference strains of Bacteroides fragilis subsp. fragilis showed that they grow well in a minimal defined medium containing glucose, hemin, vitamin B(12), minerals, bicarbonate-carbon dioxide buffer, NH(4)Cl, and sulfide. The vitamin B(12) requirement of 0.1 ng/ml was replaced with 7.5 mug of methionine. Cysteine or sulfide was an excellent source of sulfur, thioglycolate was a...
متن کاملBacteroides fragilis meningitis.
A fatal case of pyogenic meningitis due to Bacteroides fragilis in a 6-year-old boy is reported. The need for processing cerebrospinal fluid of patients with underlying conditions such as chronic otitis media for recovery of both aerobes and anaerobes is discussed.
متن کاملSuperoxide dismutase in Bacteroides fragilis and related Bacteroides species.
Superoxide dismutase (SOD) activity was demonstrated in cell-free extracts of Bacteroides fragilis, Bacteroides vulgatus, Bacteroides distasonis, Bacteroides ovatus, and Bacteroides thetaiotaomicron. The strains were grown under anaerobic conditions in Trypticase soy broth, and the specific activity of SOD in the extracts was, in most strains, higher than in cell-free extracts of Escherichia co...
متن کاملProperties of the penicillin-binding proteins of four species of the genus Bacteroides.
The penicillin-binding proteins (PBPs) of four species of the genus Bacteroides were examined in cell envelope preparations from exponentially growing cultures and intact cells. Upon examination by sodium dodecyl sulfate-polyacrylamide electrophoresis, three major high-molecular-weight PBPs (molecular weight, 58,000 to 82,000) were resolved, and low-molecular-weight PBPs were seen in all strain...
