Abstract

Summary

The minimum inhibitory concentrations of trimethoprim and sulphamethoxazole were determined for 209 strains of isolated mainly in the Greater London area. All strains were sensitive to trimethoprim at a concentration of 0.32 μg per ml, but 74 per cent. of strains were resistant to sulphamethoxazole at a concentration of 100 μg per ml.

Potentiation of trimethoprim by sulphamethoxazole was demonstrated in the case of sulphonamide-sensitive strains but there was little or no potentiation in the case of sulphonamide-resistant strains.

The possible value of the combination of trimethoprim and sulphamethoxazole in the treatment of Sonne dysentery is discussed briefly.
