Disseminated Cryptosporidium Parvum infection in a post renal transplant child

Cryptosporidium species are parasitic protozoans causing diarrhoea following the ingestion of oocyst contaminated food or water. Disease severity and duration vary with the host immune status. Cryptosporidiosis has emerged as a cause of severe persistent diarrhoea in solid organ transplant patients. Even though the infection is self-limiting among immunocompetent hosts, it can lead to disseminated disease in immunocompromised persons. Here we report a case of Cryptosporidium parvum infection of a 5-year-old boy, 4 months following kidney transplantation, to elaborate the complexities of management.
