Clinical Information
  • An infectious fungal disease that occurs most often in the skin, ears, nasal sinuses, and lungs of people with suppressed immune systems.
  • Aspergillosis is a disease caused by a fungus (or mold) that is very common in the environment. There are different kinds of aspergillosis. One kind is allergic bronchopulmonary aspergillosis (also called abpa). Symptoms of abpa include wheezing and coughing. Abpa can affect healthy people but it is most common in people with asthma or cystic fibrosis.another kind is invasive aspergillosis, which invades and damages tissues in the body. It usually affects the lungs, but it can also cause infection in other organs and spread throughout the body. It affects people who have immune system problems, such as people who have had a transplant, are taking high doses of steroids, or getting chemotherapy for some cancers.your doctor might do a variety of tests to make the diagnosis, including a chest x-ray, ct scan of the lungs, or examining tissues for signs of the fungus. Treatment is with antifungal drugs. Centers for Disease Control and Prevention.
  • Disease condition caused by species of aspergillus and marked by inflammatory granulomatous lesions in the skin, ear, orbit, nasal sinuses, lungs, and sometimes in the bones and meninges.
  • Infections with fungi of the genus aspergillus.
