Examination of 15,844 clinical specimens submitted over 12 years (1973 to 1985) to the anaerobic microbiology laboratories in two military hospitals demonstrated the recovery of anaerobic bacteria in 4,458 (28.1%) specimens. The specimens yielded 6,557 anaerobic isolates (1.47 isolates per specimen). Bacteroides spp. accounted for 43% of all isolates; anaerobic gram-positive cocci, 26%; Clostri...

The aim of the present study was to assess the application of monoclonal antibodies to the detection of black-pigmented Bacteroides spp. in subgingival plaques by immunoslot blot assay. Subgingival plaque samples from adult periodontal patients were examined by immunoslot blot assay with monoclonal antibodies that specifically recognize Bacteroides gingivalis, Bacteroides intermedius serogroups...

The in vitro activity of cefmetazole versus that of other antimicrobial drugs was assessed against 374 clinical isolates of Bacteroides spp., Clostridium spp., and anaerobic gram-positive cocci. Compared with cefoxitin, cefmetazole showed good activity against Bacteroides fragilis, other Bacteroides species, and anaerobic cocci. It was somewhat less active than cefoxitin against Bacteroides the...

The activity of ABT-773, a novel ketolide antibiotic, against clinical isolates of anaerobic bacteria was determined and compared to the activities of other antimicrobial agents. MICs at which 90% of isolates were inhibited (MIC(90)s) were </=0.06 microg/ml for Actinomyces spp., Clostridium perfringens, Peptostreptococcus spp., Propionibacterium spp., and Porphyromonas spp. The MIC(50)s and MIC...

Concentrations of fecal indicator bacteria (FIB; e.g. Escherichia coli, and Enterococcus sp.) can only be used in limited ways for determining the source of fecal contamination in recreational waters because they cannot distinguish human from non-human fecal contamination. Several Bacteroides spp. have been suggested as potential alternative indicators. We have developed a rapid, culture-indepe...

The in vitro antibacterial activity of the antifungal compound fenticonazole was compared with those of clotrimazole, miconazole, tetracycline, and metronidazole against 177 strains of bacterial species associated with either bacterial vaginosis (BV) or skin infections by agar dilution MIC determinations. BV-associated Bacteroides isolates of the Bacteroides melaninogenicus-B. oralis group, Gar...

The activity of cefbuperazone against 266 strains of anaerobic bacteria was determined by the agar dilution method and compared with cefoxitin, moxalactam, piperacillin, and clindamycin. All strains were recent clinical isolates from community hospitals. All agents tested showed good activity against Bacteroides fragilis, Fusobacterium spp., Propionibacterium spp., Clostridium septicum, Clostri...

We evaluated in vitro activity of ceftolozane-tazobactam (TOL-TAZ), formerly CXA-201, against recent clinical anaerobic isolates with emphasis on the Bacteroides fragilis group. Ceftolozane-tazobactam showed good activity against B. fragilis species and intermediate to limited activity against other species of Bacteroides. Ceftolozane-tazobactam showed very good activity against Prevotella spp....

Rumen bacterial strains can potentially be manipulated to perform functions different from wild type species. The most numerous species of bacteria in the rumen and gut are species of the familyBacteroidetes, whichcan have the potential for genetic modification for enzyme production. One of the genetic manipulation of rumen bacteria can perform for production of starch digestive enzyme for the ...

OBJECTIVES Routine susceptibility testing of all anaerobic organisms is not advocated, but it is useful for laboratories to test periodically for anaerobic organisms and provide local susceptibility data to guide therapy. This study reports the national trend of antibiotic susceptibility of clinically significant anaerobes in New Zealand. METHODS Clinical isolates were tested using standardiz...
