Bristol Centre for Antimicrobial Research and Evaluation, North Bristol NHS Trust and University of Bristol, Department of Medical Microbiology, Southmead Hospital, Westbury-on-Trym, Bristol BS10 5NB, UK
The in vitro potency of BAL 9141, a new pyrrolidinone cephalosporin, was tested against non-duplicate strains of anaerobic bacteria. The MIC50 was 1 mg/L against Actinomyces species, Clostridium species, Gram-positive anaerobic cocci, Porphyromonas species, Fusobacterium species, Lactobacillus species, Prevotella species and Veillonella species. The MIC50 was 16 mg/L for Bacteroides fragilis and other Bacteroides species. BAL 9141 was not active against cefoxitin-resistant Bacteroides fragilis.
