CAZORLA PERFETTI, Dalmiro José; ACOSTA QUINTERO, María Eugenia  y  MORALES MORENO, Pedro. Epidemiological aspects of intestinal coccidiosis in a rural community of Paraguaná peninsula, Falcon state, Venezuela. Rev. Univ. Ind. Santander. Salud [online]. 2018, vol.50, n.1, pp.67-78. ISSN 0121-0807.


Intestinal coccidioses caused by Cryptosporidium sp., Cystoisospora belli and Cyclospora cayetanensis are parasitic diseases of major clinical importance in Public Health.


Between April to June 2015, a prospective, descriptive and cross-sectional survey was designed to determine the prevalence and epidemiological profiles of intestinal coccidioses in 188 inhabitants of “El Hato”, Falcon State, Venezuela.


Probable risk factors for intestinal coccidioses were identified by using epidemiological questionnaires. The diagnosis of coccidian infection was made by direct wet-mounting and Kinyoun staining.


The overall prevalence of intestinal parasitosis was 64.36%, and Blastocystis spp. was the most prevalent taxa (39.89%). Enterococcidioses prevalence was 37.23%, detecting prevalence values of 32.98% for Cyclospora cayetanensis, 26.60% for Cryptosporidium spp. and 3.19% for Cystoisospora belli. Multiple logistic regression analysis allowed us to determine as independent potential risk factors for transmission of these enterococciodioses: inappropriate hand washing [Odds Ratio (OR) = 1.89], fast food consumption (OR=1.26), major use of water for personal and clothes washing (OR=2.88), low socio-economic status (level IV/V-Graffar) (OR=1.41), mother’s educational status (primary/secondary school) (OR=0.53), non-daily home cleaning (OR=2.95), and keeping domestic animals (OR=2.06).


Findings of this study showed that infections caused by intestinal coccidian infections are still remains as a serious health problem in rural areas of Venezuela.
