Ooquistes de Cryptosporidium sp. (Apicomplexa: Cryptosporidiiadae) y presencia del C. parvum en niños de Costa Rica

Abstract

From 1982 to 1987 infant and preschool Costa Rican children with acute diarrhea were studied. Cryptospo­ ridium (Tyzzer 1912) and other agents of diarrhea were invetigated. Criptosporydium oocysts were diagnosed in Giemsa and acid-fast (Kinyoun) stained smears. Ten Cryptosporidium oocysts per positive smear were systemalically measured. Giemsa stained oocysts showed less variation respect to the mean. The oocysts corresponded to C. parvum with diameters of 5.0 x 4.5 µm but not to C. muris with oocysts of 7.4 10 5.6 µm.
