LEMUS-ESPINOZA, Druvic et al. Enteroparasites in children under 12 years old at Anzoategui State, Venezuela. Rev. Soc. Ven. Microbiol. [online]. 2012, vol.32, n.2, pp.139-147. ISSN 1315-2556.

Intestinal parasitic diseases represent one of the most important health problems in Venezuela from both public health and socioeconomic development points of view. The main objective of this study was to determine the prevalence of enteroparasites in children under 12 years old at 45 communities of Anzoategui State, Venezuela. The study included the analysis of 5,876 samples taken by direct examination and Kato concentration, and the geotopographic characteristics were described by municipality, identifying the marker parasite per locality. The overall prevalence was 74.6%, significantly higher in children 4-9 years old (53.8%). Globally, protozoa predominated (82.5%): Blastocytis spp. (25.9%), Giardia intestinalis (20.6%) and Entamoeba coli (18.4%). Among helmints, the most common were Ascaris lumbricoides (6.9%), Trichuris trichiura (6.4%), and hookworms (2.7%). It was concluded that there is a high prevalence of enteroparasites in the child population of the Anzoategui State geography evaluated, which includes a mountainous region with its piedmont and the plane regions of the Guanipa mesa. The polyparasitism at the expense of commensals observed in some communities reflects their precarious sanitary conditions, especially regarding the quality of the drinking water available, suggesting that health education activities be carried out frequently to decrease this public health problem.
