Abstract

Summary: Seven antimicrobials--clindamycin, penicillin, ampicillin, cloxacillin, erythromycin, lincomycin and cephalexin--were found to have a high degree of activity in vitro against 256 isolates of gram-positive bacteria and Hemophilus influenzae. Clindamycin was clearly superior against staphylococci and 3.12 mug/ml or less of clindamycin inhibited all 35 isolates of H. influenzae. Synergism was not demonstrated when clindamycin was tested in combination with sulfisoxazole or sulfamethoxazole by either the agar dilution or 24-hour growth curve method. This was true for penicillin as well, and the effect was independent of sulfonamide sensitivity. The erythromycin-sulfonamide combination was synergistic against 6 of 10 strains studied by the growth curve method; this effect was not demonstrable by the agar dilution method.
