Studies also suggest that oral bacteria and the inflammation associated with periodontitis â a severe form of gum disease â might play a role in some diseases. In addition, certain diseases, such as diabetes and HIV/AIDS, can lower the body's resistance to infection, making oral health problems more severe.
Jock itch, also called tinea cruris, is a common skin infection that is caused by a type of fungus called tinea. The fungus thrives in warm, moist areas of the body and as a result, infection can affect the genitals, inner thighs, and buttocks. Infections occur more frequently in the summer or in warm, wet climates.
The most common fungi to cause skin infections are the tinea group of fungi. For example, athlete's foot (tinea pedis) is a common fungal infection of the toes and feet. Tinea infection also causes ringworm (tinea corporis) and ringworm of the scalp (tinea capitis). It also causes many fungal nail infections. A common fungal infection of the mouth and of the vagina is called thrush.
