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.
Common fungal skin infections are caused by yeasts (such as Candidaâsee Candidiasis) or dermatophytes, such as Epidermophyton, Microsporum, and Trichophyton (see Overview of Dermatophytoses (Ringworm, Tinea)). Many such fungi live only in the topmost layer of the epidermis (stratum corneum) and do not penetrate deeper.
The symptoms of a fungal skin infection depend on the type of fungus thatâs caused it, and where it is. Fungal rashes can sometimes be confused with other skin conditions, such as psoriasis and eczema. Fungal skin infections can cause a variety of different skin rashes. Some are red, scaly and itchy.
