For a long while acne was considered a bacterial infection; scholars quarreled whether aerobes or anaerobes were the infectious agents. The lesions shared features with pyodermas, namely, redness, tenderness, and, above all, suppuration. Injection of cultured organisms even produced pustules. In addition antibiotics were beneficial. Nonetheless, the question “do bacteria cause acne?” has given way to the more subtle one “do bacteria play any role in acne?”
