The aim of this study was to determine the seroprevalence of Toxoplasma gondii in pigs from technologically advanced and nontechnical farms in Lima, Peru and to identify factors associated with the transmission. Epidemiological surveys were applied on farms to identify potential factors associated with the transmission of T. gondii in pigs. Blood samples were collected in the slaughterhouse from pigs in the finishing phase: 264 from technologically advanced farms and 143 from nontechnical farms. Serum samples were analyzed for the diagnosis of swine toxoplasmosis by the indirect ELISA technique. The association between seroprevalence of T. gondii and variables sex, origin, animal density, water source, housing, presence of cats and rodent control were analyzed using multiple models of logistic regression. The seroprevalence of T. gondii in pigs from technologically advanced and nontechni...

El objetivo del presente estudio fue determinar la seroprevalencia de Toxoplasma gondii en cerdos procedentes de siete granjas tecnificadas y 10 granjas no tecnificadas de Lima, Perú, e identificar los factores asociados a su transmisión. Se aplicaron encuestas epidemiológicas en las granjas para identificar los factores potenciales asociados a la transmisión de T. gondii. Las muestras de sangre fueron colectadas en la fase de acabado en el camal, donde 264 eran procedentes de granjas tecnificadas y 143 de crianzas no tecnificadas. Las muestras de suero fueron analizadas para el diagnóstico de toxoplasmosis mediante la técnica de ELISA indirecta considerando como positivos porcentajes de positividad cocientes mayores o iguales a 20%. La asociación entre la seroprevalencia a T. gondii y las variables sexo, procedencia, densidad animal, fuente de agua, tipo de alojamiento, presencia...

The aim of the present study was to determine the concordance between the indirect hemagglutination test (HAI) and the enzyme-linked immunosorbent assay (ELISA) to detect anti-Toxoplasma gondii IgG in the diagnosis of porcine toxoplasmosis. Blood samples were collected from 407 pigs in the finishing phase, from pig farms located in the coastal strip of the department of Lima, Peru. The concordance of the diagnostic techniques and the corresponding seroprevalence were evaluated using the Kappa index and the McNemar test. The results indicated that the concordance between the HAI and ELISA tests through the Kappa index was 26%, considering the regular type, with values of 18.7 ± 3.8% by the HAI method and 14.7 ± 3.4% by the method of ELISA; while no significant differences were found by the McNemar test, which could suggest that both techniques are mutually replaceable. However, it is co...
