In a previous study, we compared HMR 3004 with azithromycin, clarithromycin, erythromycin and roxithromycin against 502 anaerobic bacteria using NCCLS-approved procedures. This report extends this study by reporting the activity of telithromycin (HMR 3647) against these strains. Telithromycin inhibited 10% of Bacteroides fragilis, 50% of other B. fragilis group organisms and 93% of other Bacteroides spp. Telithromycin inhibited all Porphyromonas spp. and 98% of Prevotella spp. Activity against Bilophila wadsworthia (8596%) was excellent. Telithromycin was not active against the Fusobacterium mortiferum/varium group. Telithromycin inhibited 100% of Clostridium perfringens, 4656% of Clostridium difficile and Clostridium ramosum and approximately 90% of non-spore-forming Gram-positive bacilli.
