Abstract

Cryptosporidium has been recognized as an emerging zoonotic agent of intestinal cryptosporidiosis leading to diarrhea, malabsorption syndrome, and weight loss in AIDS patients. In the present case, oocysts of zoonotic Cryptosporidium parvum were detected in the sputum and stool samples of an AIDS patient with a 3-month history of intestinal cryptosporidiosis. The oocysts were detected by modified Ziehl–Neelsen staining; confirmation was achieved by nested polymerase chain reaction (PCR), targeting the most polymorphic region of the 18S rRNA gene. Genotyping was done by restriction endonuclease digestion of the PCR product. The zoonotic C. parvum bovine genotype was identified in both intestinal and respiratory samples. Treatment with both azithromycin and paromomycin resulted in improvement of both intestinal and respiratory symptoms, as well as the elimination of the parasite. This is the first report of the identification of Cryptosporidium sp. oocysts in the respiratory samples obtained from an AIDS patient in Iran. Pulmonary cryptosporidiosis should be considered whenever an AIDS patient with intestinal cryptosporidiosis develops respiratory symptoms.
