Tenencia de cerdos y letrinas como factores de riesgo de parasitosis intestinales en dos comunidades de Guerrero, México

Objective: To determine the prevalence of intestinal parasites in humans and its relationship with some risk factors in two communities of Guerrero, Mexico. Material and methods: Diagnosis was made using the Faust technique and copro-ELISA. A survey was conducted in parallel to gain information on aspects that favor parasitosis. Results: 305 individuals were evaluated. Of these, 181 (59.3%) were positive according to Faust. The most frequent parasite was Ascaris sp., with 118 positive cases (38.7%); significant variations were observed between both communities, as 101/184 (54.9%) were identified in Yoloxóchitl, while only 17/121 (14.05%) were found in Zentixtlahuaca. With regard to the assessment of risk due to the ownership of latrines and pigs, the presence of the latter was found to be a risk factor for taeniosis (p = 0.013), while pig ownership showed protection against other parasitosis in the population (p = 0.03); no significance was found between having latrines and not having latrines. Conclusions: The results of coproparasitoscopic examination suggest that, while cohabitation with pigs could be a protective or a risk factor, depending on the situation, they surely also depend on other conditions, such as open defecation and the consumption of meat with metacestodes, so a comprehensive approach should be applied to solve them.
