Abstract
Intestinal cryptosporidiosis was diagnosed in 3 infants (aged 6-21 mo.), 1 child (aged 3 yr) and 2 adult members of 2 families after their return from travel to the African continent. Examination of stools from all patients revealed acid-fast cryptosporidial oocysts on direct fecal smears stained by the modified cold Kinyoun technique. Five of the 6 were symptomatic with watery diarrhea, anorexia and abdominal pain. Elevated anticryptosporidial titers were detected in 5 patients, 2 of whom were asymptomatic. Cryptosporidiosis should be included in the differential diagnosis of traveler''s diarrhea.
