Picture of Candidiasis (Moniliasis)
Candidiasis is a fungal infection caused by an overgrowth of Candida yeasts, most commonly Candida albicans. Yeasts and bacteria like Streptococci and Staphylococci occur normally on the skin; overgrowth of any of these organisms can be a problem. The skin infection of the lips (perlèche) is often due to a mix of organisms including C. albicans and bacteria. For these reasons, combination treatment with nystatin and a topical antibiotic is often warranted. Candidiasis is more difficult to treat in people who have compromised immune systems.
