he sceptibilities of 50 strains of Bacteroides fragilis

isolated from clinical specimen

to 15kiM

of antimictobial agents were tested.Minimal inhibitory concentration.(MIC) and minimalbactericidal concentrations(MBC)of drugs were determined employins micro-dilution metbod. Th

results indicated that these straing were resistant to some antimicrobial agents. The choiceof sensitive drugs for patients infected with anaerobic bacteria was suggesred.
