Resumen
El presente trabajo trata sobre la “Prevalencia de Angiostrongylus cantonensis en caracoles africanos (Lissachatina fulica) en los principales parques de Guayaquil. Periodo 2013”. En el año 2013 se recolectaron y se diseccionaron 225 caracoles (Lissachatina fulica) en el Laboratorio del Sub-Proceso de Parasitología del Instituto Nacional de Investigación en Salud Pública (INSPI) de la ciudad de Guayaquil. Estas muestras fueron analizadas en función de su prevalencia en cinco parques de masiva concurrencia. De los cuales, sólo 33 caracoles, que equivale al 14.6%, resultaron positivos para Angyostrongylus cantonensis. Se obtuvieron mayores resultados en los meses de lluvia (enero a mayo) con 26 caracoles positivos con una prevalencia del 17.33%; y en los meses secos (junio a noviembre) con 7 caracoles positivos obteniendo así una prevalencia de 9.33% para A. cantonensis. En el Parque de Urdesa, en el mes de febrero, se encontró 16 caracoles positivos para A. cantonensis. En los otros parques muestreados se encontró una alta cantidad de caracoles demostrando así la dependencia y existencia del parasito A. cantonensis con el caracol Lissachatina fulica, quien depende a su vez, de la influencia de los meses lluviosos. Según este estudio realizado el caracol gigante africano (Lissachatina fulica) es un riesgo a nivel de salud humana y animal, debido a la presencia del parásito A. cantonensis que posee en su interior. Siendo la causa de enfermedades por contacto directo o contaminación de los alimentos que se encuentran en el medio.
This work deals with the "Prevalence of cantonensis angiostrongylus in African snails (Lissachatina fulica) in major parks Guayaquil. Period 2013". In 2013 were collected and 225 snails (Lissachatina fulica) were dissected in SubProcess Laboratory of Parasitology, National Institute of Public Health Research (INSPI) of the city of Guayaquil. These samples were analyzed according to their prevalence in five parks massive turnout. Of these, only 33 snails, equivalent to 14.6% tested positive for Angyostrongylus cantonensis. Better results were obtained in the rainy season (January to May) with 26 positive snails with prevalence of 17.33%; and in the dry season (June to November) with 7 positive snails thus obtaining a prevalence of 9.33% for A. cantonensis. In Urdesa Park in February, 16 positive snails to A. cantonensis was found. On the other sampled parks a high amount of snails found demonstrating the existence of the parasite dependence and A. cantonensis with snail Lissachatina fulica, who is in turn, influence the rainy months. According to this study the giant African snail (Lissachatina fulica) is a risk level of human and animal health due to the presence of A. cantonensis parasite that has inside. Diseases being caused by direct contact or contamination of food that are in the environment.
