Antibacterial, antimycotic and trichomonicidal activity of a new nitroimidazole (EU 11100).

ABSTRACT

The antimicrobial profile of a new nitroimidazole derivative (5-nitro-1-methyl-imidazolyl-2-hydroxy-3 terbutylphenyl carbinol) has been studied. The in vitro activity of the new molecule has been evaluated against both aerobic and anaerobic bacteria, Trichomonas vaginalis, and mycetes, under suitable experimental conditions. The new compound was compared with ampicillin against aerobic bacteria; with metronidazole against anaerobic bacteria, lactobacilli and T. vaginalis; with nistatin and econazole against candida and with econazole and bifonazole against filamentous fungi. The new nitroimidazole derivative has been shown to be moderately active against some anaerobic bacteria belonging to both the Gram-positive and Gram-negative groups. Its inhibitory activity against T. vaginalis was similar to that of metronidazole.
