Beta-lactamase-negative strains were more susceptible to most antimicrobials than beta-lactamase-positive strains, with the exception of the cephamycins. Beta-lactamase-negative Bacteroides distasonis and Bacteroides ovatus were more resistant to beta-lactam/beta-lactamase inhibitor combinations than were ...
melaninogenicus, 25 were recovered from tonsils. These observations indicate that in pediatric patients there is a significant incidence of beta-lactamase producers among anaerobes other than B. fragilis. 展开 关键词: Humans Bacteroides Tonsillitis beta-Lactamases Child Penicillins ...
These bacteria are resistant to penicillins, mostly through the production of beta-lactamase. They are part of the normal GI florae [2] and predominate in intra-abdominal infections and infections that originate from those florae (eg, perirectal abscesses, decubitus ulcers). Enterotoxigenic B fragi...
Carbapenem resistance in Bacteroides fragilis is associated with cfiA-encoded class B metallo-beta-lactamase. cfiA-negative and cfiA-positive isolates belong to genotypically distinct groups. Of a total of 248 B. fragilis isolates included in this study, 214 were susceptible, 10 were intermediate, ...
humans that is one of the most important causes of morbidity and mortality in children (Boleij et al., 2014;Chen et al., 2015;Prindiville et al., 2000). The most frequently used antibiotics for the treatment ofB. fragilisinfections areclindamycin,cephamycins, beta-lactam/beta-lactamase ...
Penicillin is added to clindamycin to supplement its coverage against Peptostreptococcus species and other gram-positive anaerobic organisms. Penicillin still is the drug of choice for bacteremia caused by non–beta-lactamase producers. However, other agents should be used for the therapy of bacteremia...
Its capsule is capable of inducing abscess formation independently; characteristically, this species produces a β-lactamase that inactivates β-lactam antibiotics such as the penicillin and cephalosporin groups; it is the type species of the genus, Bacteroides.

The limited number of the antimicrobials, such as carbapenems, beta-lactam/beta-lactamase inhibitors and nitroimidazoles are highly effective in eliminating Bacteroides. However, a few metronidazole-resistant isolates have been reported from several countries recently. The nim genes (nim A-G) are ...
