Coccidiosis y amibiasis intestinal en niños de edad escolar de un distrito de Lambayeque, Perú.

Objectives: To determine the prevalence of and risk factors for intestinal coccidiosis and amebiasis in school-age children in the district of Chongoyape, Chiclayo, Peru. Methods: Cross-sectional study carried-out between November 2014 and January 2015 among 133 school-aged children. A structures questionnaire collected sociodemographic and sanitation information. Serial stool samples were required, which were processed under direct microscopy, modified acid-fast staining and ELISA to detect antigens of Cryptosporidium spp, while direct microscopy and ELISA were used to detect Entamoeba hystolitica. Results: 6.8% (9/133) of the samples were positive for coccidian parasites, 3.8% (5/133) were positive for Cryptosporidium and 3% (4/133) for Cyclospora cayetanensis, no Cystoisospora belli was identified. E. hystolitica was found in 4.5% (6/133) samples. Drinking non-potable water was a risk factor for getting both infections, while animal contact was associated with getting a coccidian parasite (p=0.013). Conclusions: Both coccidian and intestinal amebas are frequent protozoan infections in this population. These parasites are public health problem that require routine and specific diagnostic methods in the region. [ABSTRACT FROM AUTHOR]
