Yeast infections are caused by the fungus Candida albicans, one of many fungi that reside harmlessly in the vagina, mouth, throat and skin. The slightly acidic chemical content of the vagina controls the balance between the bacteria and yeast that reside in the normal vagina. If the fragile balance between acidity and alkalinity is altered, the amount of yeast grows to the extent that a Candida infection (known as candidiasis) occurs. A similarly uneasy truce exists between âfriendlyâ bacteria (lactobacilli) and âunfriendlyâ bacteria (anaerobes).
