Comparison of antibiotic susceptibilities of four species of coagulase-negative staphylococci isolated rom normal skin and acne Lesions: a statistical approach

Abstract

Ten strains of each of four species of coagulase negative staphylococci: S. epidermidis, S. hominis, S. capitis, and S. cohnii isolated from both acne lesion and normal skin (total 80 strains) were tested for their antibiotic susceptibilities. Statistical analysis has shown significant differences among strains. Strains of acne lesions were more resistant. The antibiotics clindamycin and gentamycin were found to have superior effect over ampicillin, penicillin, streptomycin and tetracyclin.
