Microbiological findings about pulmonary cryptosporidiosis in two AIDS patients

There is no known treatment for pulmonary cryptosporidiosis, a rare complication of intestinal cryptosporidiosis in AIDS patients. We report two cases of cryptosporidiosis which were unusual because (i) extracellular invasive forms of the parasite were found in the bronchoalveolar lavage and (ii) the outcome was favorable in one patient after treatment with azithromycin.
