Sensitivity in vitro of leptospira to oxamicetin

Oxamicetin was tested against 12 strains of parasitic leptospira each representing a different serotype and serogroup, and 8 saprophytic strains in liquid media. The results showed general susceptibility of parasitic leptospira being MIC's from 0.1 to 0.5 mug/ml. The MIC's against saprophytic strains were 10 similar to 40 mug/ml.
