Answer

In patients with related symptoms, bronchoscopy may reveal the parasite in lavage fluid, in brushing specimens, and in biopsy specimens attached to the surface of bronchial mucosal cells or in macrophages. In most instances, another pulmonary pathogen, such as CMV or Pneumocystisjiroveci, is concurrently detected; however, in a series of 4 patients infected with HIV, Cryptosporidium was the only pathogen identified in the respiratory tract. Clear association with intestinal cryptosporidiosis or diarrhea has not been shown in these cases.
