At the time of sampling, all 30 cases of study group had been on therapy for a minimum of 4 months on oral tetracycline and topical clindamycin and erythromycin 30 patients were included in the control group without previous history of antibiotic therapy. Mic (Minimum Inhibitory Concentration) was performed on PA or SE isolated from skin surface of these cases. Erythromycin resistant PA and SE isolated from antibiotic treated acne patients was 43.3% (P=0.024). Tetracycline resistant PA and SE isolated from study group was 40% (P CP - IRAN IN - LG - eng PB - RJMS PG - 427 PT - Research YR - 2002
