Estudio comparativo de enteroparasitosis entre poblaciones rurales de San Andrés. Guano. Chimborazo, 2022

ABSTRACT: This study compared the prevalence of Enteroparasitosis among the inhabitants of the villages of Calshi Grande, Calshi Hierva Buena, La Silveira, El Rosal and Tatacto, using parasitological diagnostic techniques and statistical tests to identify the most affected community, gender, and age group. A descriptive, field, non-experimental, cross-sectional, and prospective study was conducted, in which 165 samples of individuals between 4 and 97 years of age were analyzed, by direct examination, concentration techniques (Ritchie, Kato-Katz) and acid fastness-alcohol staining (modified Ziehl-Neelsen). The results showed an average prevalence of 99.4% in the five communities, with a predominance of Blastocystis sp., 98.2% (x2= 965.497; p= 0.0001), where the Calshi Hierva Buena community was the most affected, revealing a significant difference for Entamoeba coli with 80% (x2= 11.413; p= 0.0223), as in Calshi Grande where the difference was centered on Hymenolepis nana with 16.7% (x2= 9.380; p= 0.0523). In the town of Calshi Grande there was a higher prevalence of E. coli 88% (x2= 8.191; p= 0.0042) in the female sex. Adults were found to be more parasitized than underage, however, a higher prevalence of H. nana 11.1% (x2= 4,500; p= 0.0339) was found in children and adolescents. In conclusion, all populations presented a considerable prevalence of intestinal parasitism; regardless of gender or age group, since both children and adults are exposed to infection with entoparasites. Keywords: intestinal parasitosis, prevalence, protozoa, helminths, communities.
