Pulmonary cryptosporidiosis in a bone marrow transplant recepient

ABSTRACT

Cryptosporidium, a protozoan parasite of Phylum Apicomplexa, causes acute short term intestinal infection in immunocompetent individuals. However, in immunocompromised patients, it causes prolonged and life threatening watery diarrhea, rarely with extra-intestinal involvement. We present a case of Cryptosporidium parvum with pulmonary involvement who was managed with azithromycin and co-trimoxazole combination. This is the second reported case in the world in HIV negative patient undergoing bone marrow transplantation
