in-vitro antibiotic susceptibility and molecular analysis of anaerobic bacteria isolated in cape town, south africa.one hundred and twenty-three anaerobic isolates from cape town, south africa, were tested in vitro against cefoxitin, chloramphenicol, metronidazole, co-amoxiclav, benzylpenicillin and clindamycin. forty-five gram-positive organisms were tested against rp59500 (a streptogramin). resistance in the gram-positive isolates was as follows: of the clostridium perfringens isolates, 4% were resistant to benzylpenicillin and 4% to clindamycin; of the peptostreptococcus anaerobius isolates, 10% were resis ...19989738844
antibiotic resistance and adhesion potential of bacteroides fragilis clinical isolates from cape town, south africa.the minimum inhibitory concentrations of 23 bacteroides fragilis clinical isolates from cape town, south africa, were established using the e-test method. eight percent of the strains were found to be highly resistant to metronidazole (≥256 mg/l) imipenem and cefoxitin. this is an 8% increase in resistance compared to the previous metronidazole susceptibility screening performed in south africa in 1998. clindamycin was the most effective antibiotic with all strains showing sensitivity. most of t ...201121530667
