Treatment of Anaerobic Infections with Metronidazole

Abstract

Metronidazole (Flagyl®), a compound widely used in man with minimal side-effects, has been used in the treatment of anaerobic infections caused by Bacteroides fragilis and other Bacteroides species. Seven patients were treated and all were restored to full health. Four of them did not respond to lincomycin or clindamycin which so far have been the drugs of choice against anaerobic infections. The reasons for the good results during metronidazole therapy such as the good penetration through the blood/brain barrier and into abscess cavities are discussed.
