RESUMO

When tested on Wellcotest (sensitivity test agar, Wellcome) supplemented with lysed horse blood, 59 clinical isolates of beta-haemolytic streptococci, belonging to several serological groups, are all sensitive to sulphamethoxazole, to trimethoprim, and to cotrimoxazole. The results obtained on diagnostic sensitivity test agar (Oxoid) containing lysed horse blood are comparable. When Mueller Hinton agar (Difco) is used, some of these strains are called resistant: this is especially true in the case of sulphamethoxazole.
