Hydrolysis of Cefotaxime by a beta-lactamase from Bacteroides fragilis.
نویسندگان
چکیده
A beta-lactamase isolated from a strain of Bacteroides fragilis subsp. fragilis possessed hydrolytic activity toward cefotaxime. This antibiotic was degraded to a lower extent than was cephalothin, cephaloridine, and cefamandole, whereas cefoxitin remained unaffected by the enzyme. Kinetic parameters Vmax and Km for cefotaxime were calculated at 0.172 mumol/min and 1.1 X 10(-2) mM, respectively.

Effect of clavulanic acid on the activities of ten beta-lactam agents against members of the Bacteroides fragilis group.
Clavulanic acid reduced the MICs of amoxicillin, carbencillin , cefamandole, cefotaxime, ceftazidime, ceftizoxime, cephalothin, and penicillin G, but not of cefoxitin or moxalactam, against 77 isolates of the Bacteroides fragilis group, all rapidly beta-lactamase positive by the nitrocefin slide test. It had no effect on the susceptibilities of eight Bacteroides distasonis strains that were slo...

A retrospective analysis of susceptibility data on 542 blood isolates of the Bacteroides fragilis group tested from 1987 to 1999 by the same NCCLS-recommended broth microdilution method throughout is presented. Metronidazole, beta-lactam-beta-lactamase inhibitor combinations, carbapenems, and trovafloxacin were the most active agents (susceptibility of >or=93%). Among the cephalosporin-cephamyc...
متن کاملCharacterization of cephalosporinases from Bacteroides fragilis, Bacteroides thetaiotaomicron and Bacteroides vulgatus.
The susceptibility of 80 Bacteroides fragilis group strains isolated from clinical specimens to beta-lactam antibiotics was investigated by agar dilution method. Twenty strains showed high resistance to the antibiotics. The resistance level of the isolates to cephaloridine was related to the amount of beta-lactamase activity (cephalosporinase; CSase) produced. B. fragilis GN-11477, B. thetaiota...
متن کاملCephalosporinase 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. ...

OBJECTIVES To identify β-lactamase genes in gut commensal Bacteroides species and to assess the impact of these enzymes, when carried by outer membrane vesicles (OMVs), in protecting enteric pathogens and commensals. METHODS A deletion mutant of the putative class A β-lactamase gene (locus tag BT_4507) found in the genome of the human commensal Bacteroides thetaiotaomicron was constructed and...
