Cryptosporidium spp., a frequent cause of diarrhea in Central Africa

Abstract
Cryptosporidium oocysts were present in 20 (10.4%) of 193 Rwandese children and in 3 (3.0%) of 100 adults with diarrhea. In 4 of the children and in 1 adult, Cryptosporidium was associated with other enteric pathogens. The higher incidence of Cryptosporidium in diarrheic children was statistically significant. The parasite was not found in 94 formed stools submitted for parasitological examination. The mean age of the Cryptosporidium-positive children was 13.3 mo. In 4 children, Cryptosporidium was associated with severe malnutrition. All of those required rehydration, and 1 child died as a direct consequence of severe diarrhea. The 3 adult patients showed no recognizable immunodeficiency, and their diarrhea resolved spontaneously. Staining 1% safranin was not only more simple and rapid but also more sensitive than the modified Ziehl-Neelsen technique.
