Frequency of Ancylostoma spp. in environmental fecal samples in the public squares of Pedro Osório, RS

Abstract

Two municipal squares were monitored in the city of Pedro Osório / Two municipal squares were monitored in the city of Pedro Osório, RS, between December 2017 and November 2018, and environmental fecal samples were collected for the identification of parasites with potential zoonotic, such as Ancylostoma spp., a potential causative agent of parasitic dermatitis called Larva Migrans Cutanea (CML). The diagnostic method used was the copro-parasitological technique Willis-Mollay. The prevalence of 61.11% and 50% of Ancylostoma spp. Eggs, respectively, was obtained as a result. The sample data were submitted to statistical analysis according to Standard Normal Distribution (Z) and Confidence Interval (CI) for proportion, with a significance level of 5% (α = 1.96), obtained with CI at P1 (0, 6178 ≤ ≤ 0.6044) = 95%, and in P2 (0.5136 ≤ ≤ 0.4864) = 95%, demonstrating that there is a possibility that the local population may become contaminated with this zoonotic agent in the environment.
