Abstract

Enteric parasites Cryptosporidium spp. and Giardia spp. were studied with the purpose of determining their prevalence in calves, which contaminates the water catchment for human consumption and irrigation of San Fernando Canton, Azuay province. The methodology was based on an epidemiologic cross-section descriptive study. This study was carried out from September 2013 to April 2014. For studying the calves Ziehl Neelsen dye technique was used, which values the prevalence of Cryptosporidium spp. in 91.70% whereas Ritchie’s technique finds 76.70% of Giardia spp. prevalence. For analysis of water, samples were taken in the catchment area. EPA 1623.1 method was used, the finding was 5 oocysts of Cryptosporidium spp. x 100 ml, and 10 cysts of Giardia lamblia x 100 ml. Meanwhile, the prevalenceof Cryptosporidium spp. and Giardia lamblia in children was performed in child population under 6 years old from the area of study that came to the Health Center of San Fernando Cantonwith some health problem from November 2013 to April 2014.We obtained 14.29% of positive infections for Cryptosporidium spp. and 33.33% for Giardia lamblia.An association test according to the origin of children does not evidence significant differences for Cryptosporidium spp. but it definitely does for Giardia lamblia.
