epidemiology, antimicrobial susceptibility, pathogenicity, and significance of bacteroides fragilis group organisms isolated at los angeles county-university of southern california medical center.the epidemiology of species of the bacteroides fragilis groups isolated at los angeles county-university of southern california medical center was examined. in addition, frequency of resistance to six beta-lactam antibiotics (cefmetazole, cefotetan, ceftizoxime, imipenem, penicillin, and cefoxitin) and to clindamycin, chloramphenicol, and metronidazole was determined for each species. while b. fragilis was most commonly isolated, the other species of the b. fragilis group accounted for half of t ...19912017610
occurrence of bacteroides fragilis enterotoxin gene-carrying strains in germany and the united states.ninety-three bacteroides fragilis isolates from different geographic locations were analyzed for the presence of an enterotoxin-encoding gene. it was shown that blood culture isolates were more likely to carry this gene than strains from other sources. all enterotoxin-positive strains belonged to the pcr fingerprint group i.200010790139
infective endocarditis due to anaerobic and microaerophilic bacteria.seven cases of infective endocarditis (ie) due to anaerobic or microaerophilic bacteria were seen in a period of 42 months at rancho los amigos hospital (downey, california), representing 10.6 percent of the total number of 66 cases that carried the diagnosis of ie. five of the 66 patients had polymicrobial endocarditis. three of five patients with polymicrobial endocarditis had at least one anaerobic or microaerophilic microorganism isolated from the blood, and all five patients practiced intra ...19827135941
bone infections involving anaerobic bacteria.over 700 cases of anaerobic osteomyelitis have been reported in the literature. nonetheless, most reviews of osteomyelitis have paid little attention to the potential role of anaerobes in bone infections. there have, as yet, been no prospective studies of osteomyelitis utlizing optimal anaerobic transport and culture techniques. in a retrospective study of osteomyelitis at wadsworth va hospital from 1973--1975, 39 percent of 58 patients with osteomyelitis had an infection involving anaerobes. an ...1978207946
