In vitro & in vivo experimental susceptibility of Mycobacterium marinum to augmentin.

The effect of augmentin alone and in combination with various beta-lactam antibiotics was studied against a pathogenic Mycobacterium, M. marinum. The in vitro studies did not reveal any additional advantage over that found with augmentin alone and this antibiotic seemed considerably inhibitory to M. marinum at < 1 microgram/ml concentration. In vivo, the effects of augmentin on experimentally produced lesions in the mouse foot pads (MFPs) showed a significant regression of the lesions, which was compatible with an early disappearance of M. marinum from the MFP, in contrast with those of the untreated, control animals.
