    (2015) Criollo Ordóñez, Lourdes Cristina; Urdiales Flores, Silvia Araceli; Landívar Abril, Saúl
    This research was conducted within the parasitological field and addressed to the field of public health, considering that the problem arises when the parasite Cryptosporidium parvum infects the gastrointestinal tract of domestic and wild mammals, and can even infect humans; their polluting form are oocysts that are eliminated through feces and being washed away or being in contact with each other animals, it is critical for their pollution factor. The analysis was performed in the clinical laboratory of Faculty of Agricultural Sciences and Technology and the Ziehl Neelsen’s staining method for identification of oocysts was used, we proceeded identifying calves and 200 samples were taken with animals aged among 0 to 2 months and 2.1 to 4 months, with different type of pasture management, with and without poultry manure; a group of 50 animals was realized for each variable. The obtained results gave a percentage of 32% of positive cases of the total of the samples, being able to see that the relative frequency of the parasite by sector in the calves of Parish El Valle of the Canton Cuenca is low, in connection with a recent investigation carried out in the Canton San Fernando whose prevalence is of 91.7% (Palacios, 2014); so there is no significantly association between the variables age and presence of manure as fertilizer on pasture grounds
