The term opportunistic fungi is vague. Generally, any fungal species is capable of causing infection under favorable conditions. Over one million fungal species exist in nature. Only a few hundred of them have been associated with human and animal infections. Opportunistic fungi refers to those fungi that normally would not cause infections in otherwise healthy people but are able to cause infection under certain circumstances such as immunodefficiency, cancer, organ transplant, neutropenic patients, diabetes, debilitated patients and patients on long term antibiotics.
