causes of candidiasis
Candidiasis (yeast infection) Candidiasis is an infection caused by a group of yeasts. There are more than 20 species of Candida, the most common being Candida albicans. These fungi live on all surfaces of our bodies. Under certain conditions, they can become so numerous they cause infections, particularly in warm and moist areas. Examples of such infections are vaginal yeast infections (thrush), oral thrush, skin and nappy rash, and nail bed infections. Candidal infections commonly occur in warm moist body areas, such as underarms.
