Infection by Cryptosporidium sp. in immunocompromised haematological patients.
The frequency of intestinal infection by Cryptosporidium sp. was determined in 60 patients, attended at the Haematological and Haemotherapeutical Service of "Santa Casa de Misericórdia" of São Paulo, suffering lymphoproliferative diseases (Group 1). As control group (Group 2) 59 persons without haematological diseases, but with the same life time and living at the same place of that of haematological patients, had been examined. The stool parasitological tests performed disclosed Cryptosporidium sp. oocysts in six (10%) individuals belonging to Group 1, whereas, in Group 2, nobody showed infection by this coccidian. Among the patients infected by Cryptosporidium sp. only one showed diarrhoeal faeces.
