BACKGROUND: A rising percentage of tetracycline-resistant Propionibacterium acnes strains has been reported in the English literature.
PATIENTS AND METHODS: We studied a population of 16 patients with acne who had been treated with oral tetracyclines during the preceding year. A bacteriological examination of a skin biopsy was obtained in all patients to determine aerobic and anaerobic flora as wells as resistance to tetracycline and minocycline.
RESULTS: Staphylococcus epidermidis strains were frequently resistant to tetracycline (87.5%) as well as minocycline (30%). Tetracycline-resistant Propionibacterium acnes were also observed (7%). Inversely, we were unable to evidence any minocycline-resistant Propionibacterium acnes strains.
CONCLUSION: These findings emphasize the importance of determining whether therapeutic response is related or not to the presence of resistant strains.
