Among non-spore forming anaerobic Gram-negative bacteria, the isolation rate of Bacteroides fragilis group (64%) was highest, followed by Fusobacterium spp.(40%), Prevotella spp./Porphyromonas spp.(32%) and Bilophila wadsworthia (28%), in this order. The isolation rate of non-spore forming anaerobic Gram-positive bacteria was 60%, and that of Clostridium spp. was 24%. Even by the recent advanced methods, there were 17 strains of anaerobic bacteria, which were not identified by phenotypic-identification levels. Carbapenems and β-lactams plus β-lactamase inhibitors have strong antimicrobial activities against both aerobic and anaerobic bacteria. Although metronidazole and minocycline have strong activities against anaerobic bacteria, there were many strains highly resistant to clindamycin.
