A comparison of the antibacterial activity of sulphonamide-trimethoprim combinations

Sensitivity patterns of 326 clinical isolates toward sulphonamide/trimethoprim combinations were tested in vitro. The relative merits of the different combinations are discussed in their pharmacological and bacteriological contexts. It is concluded that organisms sensitive to cotrimoxazole as judged by in vitro sensitivity tests performed at 37 degrees C are also sensitive to sulphamoxole/trimethoprim.
