| 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 ... | 1991 | 2017610 |
| performance of human fecal anaerobe-associated pcr-based assays in a multi-laboratory method evaluation study. | a number of pcr-based methods for detecting human fecal material in environmental waters have been developed over the past decade, but these methods have rarely received independent comparative testing in large multi-laboratory studies. here, we evaluated ten of these methods (bach, bachum-ucd, bacteroides thetaiotaomicron (bth), bsterif1, gyrb, hf183 endpoint, hf183 sybr, hf183 taqman(®), humm2, and methanobrevibacter smithii nifh (mnif)) using 64 blind samples prepared in one laboratory. the b ... | 2013 | 23992621 |
