It was evaluated the prevalence and the incidence rate (force of morbidity of cysticercosis) in the period of January-April, 2000 in the porcine population of Matapalo's village (Zarumilla, Tumbes). In the first sampling, 922 animals older than 3 months were evaluated and 284 resulted positive representing a prevalence of 30.8 ± 3.0% . The second sampling, carried out three months later on 778 animals reported a prevalence of 20.8 ± 2.9%. A total of 314 negative animals at the first sampling were evaluated in the second sampling and 36 seroconverted to the EITB test resulting in an accumulated incidence of 11.5 ± 3.5%. A number of risk factors were analyzed for the prevalence of porcine cysticercosis finding out that village, age and sampling represented a factor of risk to find a positive animal. Similarly, several factors relating to incidence were analized and was found that the variables village, age, immunological condition of the mother, and sex represented risk factors to get the disease.Key words: cysticercosis, prevalence, incidense, risk factors RESUMENSe evaluó la prevalencia y la tasa de infección o la fuerza de morbilidad de la cisticercosis expresada como incidencia acumulada en el periodo de enero a abril del 2000 en la población porcina del distrito de Matapalo (Zarumilla, Tumbes). En el primer muestreo se evaluaron 922 cerdos mayores de 3 meses (con excepción de hembras en gestación avanzada), encontrándose una prevalencia del 30.8 ± 3.0%. En el segundo muestreo se evaluaron 778 cerdos, encontrándose una prevalencia de 20.8 ± 2.9%. Un total de 314 animales negativos al primer muestreo fueron evaluados en el segundo muestreo y 36 seroconvirtieron a la prueba de EITB, lo que resultó en una incidencia acumulada de 11.5 ± 3.5%. Se analizaron factores de exposición para la prevalencia de la cisticercosis porcina encontrándose que las variables caserío, edad y muestreo representaron un factor de riesgo para encontrar un animal positivo. Con respecto a la incidencia, se encontró que las variables caserío, edad, condición inmunológica de la madre y sexo representaron un factor de riesgo para contraer la enfermedad.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
