Skin infections are common and may be caused by bacteria, fungi or viruses. Breaks in the skin integrity, particularly those that inoculate pathogens into the dermis, frequently cause or exacerbate skin infections. Bacterial skin infections caused by corynebacteria include erythrasma, trichomycosis axillaris and pitted keratolysis. Staphylococci may cause impetigo, ecthyma and folliculitis. Streptococcal skin infections include impetigo and erysipelas. Human papillomavirus skin infections present as several different types of warts, depending on the surface infected and its relative moisture, and the patterns of pressure. The many dermatomycoses (skin infections caused by fungi or yeasts) include tinea capitis, tinea barbae, tinea cruris, tinea manus, tinea pedis and tinea unguium (onychomycosis). Candidal infections occur in moist areas, such as the vulva, mouth, penis, skinfolds and diaper area. Wounds caused by wood splinters or thorns may result in sporotrichosis. Animal bites may result in complex, serious infections, requiring tetanus and, possibly, rabies prophylaxis in addition to appropriate antibiotic therapy.
