El objetivo del estudio fue estimar la prevalencia de Cryptosporidium sp. en caninos de comunidades campesinas, ubicadas en los distritos de Ajoyani; provincia de Carabaya; Palca y Santa Lucía; provincia de Lampa–Puno. Se recolectaron 123 muestras fecales de perros aparentemente sanos, de ambos sexos y diferentes edades, las que estuvieron comprendidas entre 1 mes y 16 años durante los meses de febrero y marzo del 2009. Las heces, fueron transportadas inmediatamente al Laboratorio del INIA-Quimsachata (Puno) donde se realizaron los frotices fecales, siendo fijados en metanol. Posteriormente se transportaron al Laboratorio de Parasitología de la FMV-UNMSM en Lima, para su diagnóstico; el cual se realizó usando la técnica de Ziehl-Neelsen modificada. La prevalencia general de Cryptosporidium sp. fue de 26.8±7.8%, se hallaron prevalencias de 19.0, 28.6 y 28.4% en los distritos de Ajoyani, Palca y Santa Lucía, respectivamente; los machos y hembras presentaron prevalencias de 28.3 y 17.6%, respectivamente y según los grupos etarios de 0-6, >6-12, >12-72 y >72 meses fueron de 46.2, 31.3, 19.7, 29.4%, respectivamente. Se aplicó la prueba de Chi cuadrado, con un nivel de significancia de 0.05. El análisis estadístico no mostró asociación significativa (p>0.05) entre este protozoo de caninos domésticos con el distrito, sexo y edad. Palabras clave: Cryptosporidium sp, protozoo, zoonosis, prevalencia, perros. / The objective of this study was to estimate the prevalence of Cryptosporidium sp. in dogs of rural communities, located in the districts of Ajoyani; province Carabaya; Palca and Santa Lucia; province Lampa, Puno. Were collected 123 fecal samples from dogs apparently healthy, of both sexes and different ages, which were between 1 month and 16 during the months of February and March 2009. Feces were transported to the Laboratory of INIA Quimsachata (Puno) where are the faecal frotices being fixed in methanol. Subsequently were transported to the Parasitology Laboratory of the FMV-Lima, for diagnosis; which was performed using the Ziehl-Neelsen modified. The overall prevalence of Cryptosporidium sp. was 26.8±7.8%, were found prevalences of 19.0, 28.6 and 28.4% in the districts of Ajoyani, Palca, and St. Lucia, respectively, males and females, showed prevalences of 28.3 and 17.6% respectively and according to age groups 0 -6,> 6-12,> 12-72 and > 72 months were 46.2, 31.3, 19.7, 29.4%, respectively. Was applied Chi-square test with a significance level of 0.05. Statistical analysis showed no significant association (p> 0.05) between this protozoan of domestic dogs with the district, sex and age. Keywords: Cryptosporidium sp, protozoa, zoonoses, prevalence, dogs.
