Antimicrobial susceptibility and genetic characteristics of <i>Propionibacterium acnes</i> isolated from patients with acne

Abstract

Resistance to trimethoprim-sulfamethoxazole was the most common pattern found, and further studies are required to clarify its resistance mechanism. A certain tetracycline resistance was expected, but interestingly all strains remained sensitive. Resistance to erythromycin and clindamycin were influenced using topical formulations. Mutation A2059G was related to high resistance to erythromycin. Antibiotic resistance is increasing, and new strategies are needed.
