[Cryptosporidium enteritis].

Cryptosporidium has been found to be a common cause of gastroenteritis during the last years. The natural course of the disease in immunocompromised patients is often met by serious complications. A general therapy recommendation has not been reported so far. We report of a two-year-old boy, who was immunocompromised by a multidrug cytostatic chemotherapy. The patient suffered from a long lasting most severe gastroenteritis, caused by cryptosporidium. There was a good clinical response to spiramycin, a treatment suggested in the literature.
