ABSTRACT
RESUMEN El objetivo de este estudio fue examinar la prevalencia de parásitos intestinales de niños y animales domésticos en dos barrios periurbanos de la ciudad de Corrientes, Argentina. También evaluamos las características de los humanos, factores socio-ambientales y prácticas de higiene asociadas con la presencia de parásitos. Las muestras fecales fueron examinadas usando técnicas de concentración por sedimentación y flotación. Se detectaron huevos de Enterobius vermicularis en niños utilizando el método de Graham. El análisis de los datos fue univariado y bivariado. En total, 58 viviendas fueron evaluadas, de las cuales se obtuvieron 146 muestras de heces de niños y 101 muestras de animales. Se registró al menos una especie de parásito en 54 viviendas (93,1%). Encontramos parásitos en el 52,7% de los niños, principalmente los protozoos Blastocystis spp. (35,6%) y Giardia spp. (21,2%). Se detectaron parásitos en 67,32% de los animales, principalmente ancilostomídeos (60,7%). En conclusión, es evidente que el ambiente doméstico presenta condiciones favorables para la transmisión de estos parásitos.
ABSTRACT This study aimed to examine the prevalence of intestinal parasites in children and domestic animals from two peri-urban neighborhoods in Corrientes, Argentina. We also evaluated the characteristics of humans, socio-environmental features, and hygiene practices associated with the presence of parasites. Fecal samples were examined using techniques of concentration by sedimentation and flotation. The Graham method was used to diagnose Enterobius vermicularis eggs in children. We carried out the univariate and bivariate analysis of the data. We analyzed 58 dwellings, from which we obtained 146 stool samples from children and 101 from animals. We found at least one parasite species in 54 dwellings (93.1%). We found that 52.7% of children had parasites, mainly Blastocystis spp. (35.6%) and Giardia spp. (21.2%). We found that 67.32% of the animals had parasites, the most prevalent species being hookworms (60.7%). In conclusion, it is evident that the domestic environment can favor the transmission of these parasites.
ABSTRACT
Motivation for the study. There are few reports on intestinal parasites in children and domestic animals in urban areas in Argentina who live in homes with characteristics that favor the maintenance and transmission of parasites of zoonotic importance. Main findings. More than 50% of children and pets were parasitized, most of them with zoonotic pathogens. Implications. Our results showed the urgent need to improve sanitary control of children and animals, and to implement activities for the prevention of intestinal parasitosis in the homes analyzed.
