Correspondencia: Calle 65 No. E-mail: fredy. It is necessary to implement and evaluate strategies for detection and typification of different Cryptosporidium species,to adopt control measures and monitoring. To perform a comparison between microscopic and molecular methods for the detection and typification of Cryptosporidium species with the purpose of using the most sensitive method in the detection of Cryptosporidium oocysts in water samples.

Materials and methods. Detection and typification of Cryptosporidium spp, in feces and water samples were done initially using a concentration method for both feces and water Formol-ether and inorganic flocculation method with Calcium carbonate ; the parasite identification was carried out using the Ziehl-Nelseen staining and the Polymerase Chain Reaction PCR amplification of ribosomal ADN regions, of gens codified for Hsp70 protein and the gen that codifies for the Cryptosporidium oocyst wall protein COWP.

The Ziehl-Neelsen staining, confirmed the presence of Cryptosporidium spp. The sensitivity of detection of Cryptosporidium by PCR and its utility in the diagnosis is shown, registering the presence of two species of the parasite circulating in samples taken in the municipality of Manizales.

La materia fecal puede contener mucus pero la presencia de sangre y leucocitos es rara, debido a que se trata de una diarrea no inflamatoria 3. Para definir la presencia o ausencia de los ooquistes de Cryptosporidium spp. Es de anotar que todas las muestras positivas bajo la lectura al microscopio se reconfirmaron por PCR. Estos resultados son concordantes con los reportes previamente publicados 30, 31, 32 , los cuales encontraron a Cryptosporidium parvum como el principal agente causal de criptosporidiosis en humanos y animales; sin embargo, hay que tener en cuenta que C.
