Candidiasis

Candidiasis is a fungal infection due to any species of yeasts in the genus Candida or those that were formerly classified in genus Candida but are now classified in the genus Candidozyma. When it affects the mouth (oral candidiasis) it is commonly known as thrush. Signs and symptoms include white patches on the tongue or other areas of the mouth and throat.

Signs and symptoms include genital itching, burning, and sometimes a white "cottage cheese-like" discharge from the vagina. Yeast infections of the penis are less common and typically present with an itchy rash. Very rarely, yeast infections may become invasive, spreading to other parts of the body. This may result in fevers, among other symptoms. Finally, candidiasis of the esophagus is an important risk factor for contracting esophageal cancer in individuals with achalasia. More than 20 types of Candida may cause infection with Candida albicans being the most common. Infections of the mouth are most common among children less than one month old, the elderly, and those with weak immune systems. Conditions that result in a weak immune system include HIV/AIDS, the medications used after organ transplantation, diabetes, and the use of corticosteroids. Other risk factors include during breastfeeding, following antibiotic therapy, and the wearing of dentures. Vaginal infections occur more commonly during pregnancy, in those with weak immune systems, and following antibiotic therapy. Individuals at risk for invasive candidiasis include low birth weight babies, people recovering from surgery, people admitted to intensive care units, and those with an otherwise compromised immune system. Efforts to prevent infections of the mouth include the use of chlorhexidine mouthwash in those with poor immune function and washing out...
