Abstract
Objetivo. Demostrar la presencia de Echinoccocus granulosus en el hospedero definitivo en la ciudad de Lima, Perú, mediante la detección de antígenos del parásito en heces de canes pertenecientes a trabajadores y comercializadores de vísceras de centros de beneficio autorizados en Lima metropolitana. Métodos. Se recolectaron muestras de heces de 58 canes, que fueron evaluadas utilizando la técnica coproELISA para detectar antígenos secretorio/excretorio de E. granulosus. Mediante una encuesta se obtuvo información sobre las prácticas de alimentación y el manejo de las mascotas. Resultados. El 13,8% (8/58) de canes fue positivo a E. granulosus. En 27,8% (5/18) de los hogares se encontró al menos un animal positivo y se estimó que en las familias que tenían más de cuatro canes las posibilidades de encontrar al menos uno positivo eran mayores. En todos los hogares con al menos un can positivo sus mascotas se alimentaban con vísceras. El 94,4% (17) de los participantes no tenía conocimiento de las formas de contagio de la equinococosis. Conclusiones. Los resultados muestran la presencia de hospederos definitivos en la zona urbana de Lima y subrayan la necesidad de aumentar la difusión de las prácticas para evitar la transmisión del parasito.
 
Objective. To demonstrate the presence of Echinoccocus granulosus in the definitive host in the city of Lima, Perú, by detecting parasite antigens in the stool of dogs belonging to offal handlers and merchants in authorized slaughterhouses in Metropolitan Lima. Methods. Stool samples were collected from 58 dogs and examined using the coproELISA technique for the detection of secretory/excretory antigens of E. granulosus. A survey was conducted to obtain information on pet feeding and handling practices. Results. Positivity to E. granulosus was detected in 13.8% (8/58) of the dogs. In 27.8% (5/18) of the homes, at least one animal showed positivity, and in families that had more than four dogs the chances of finding positivity in at least one dog were higher (P < 0.05). In all homes where at least one dog tested positive the pets were fed on offal. Of study participants, 94.4% (17) knew nothing about the routes of transmission of hydatid disease. Conclusions. Results show the presence of definitive hosts in the urban area of Lima and underscore the need to more widely disseminate practices for the prevention of parasite transmission.
