[Presence of Cryptosporidium spp in children with acute diarrhea in a public daycare center in Recife, State of Pernambuco].

The objective of the present study was to analyze the frequency of oocysts of Cryptosporidium spp in fecal samples from children aged one to fourteen years at a public daycare center located in a needy community in the city of Recife, Pernambuco. The investigation was carried out between June 28, 2006, and April 3, 2007, and involved 182 children. Among the samples analyzed, 59 (32.4%) were positive regarding the presence of oocysts of Cryptosporidium spp, and the age group most affected was between three and five years (54.2%). The high frequency of samples positive for Cryptosporidium spp obtained in this study confirms that daycare centers are an environment that favors such occurrences, because of the direct contact between children or between children and staff. The most important infection route for Cryptosporidium spp is person-to-person transmission, which is well illustrated in daycare centers. Immaturity, deficiencies of the immune system and inadequate hygiene habits are factors that also contribute towards this type of infection.
