Opportunistic mycoses are fungal infections caused by opportunistic fungi that only affect people with weakened immune system. They do not occur in healthy people. Opportunistic mycoses are fungal infections of the body which occur almost exclusively in debilitated patients whose normal defense mechanisms against infections are impaired. Such patients include those on chemotherapy, cancer patients, […]
