Diagnóstico serológico de la prevalencia del virus de newcastle en aves de traspatio en la parroquia Tundayme del cantón el Pangui, provincia de Zamora Chinchipe

A prospective, cross-sectional study was carried out to determine the seroprevalence of Newcastle virus in backyard birds from Tundayme parish, in the province of Zamora Chinchipe. 148 blood samples were obtained by wing puncture from adult birds with no history of vaccination against Newcastle disease. An epidemiological survey was applied in each one of the properties, to evaluate the biosecurity norms and collect information about the following variables: origin (parish and neighborhoods), type of birds, types of management and characterization of the exploitation systems. The serum samples were subjected to analysis by indirect ELISA for the detection of IgG antibodies against Newcastle virus, the seroprevalence was 18.92% (28/148), the variable: presence of other species, origin of the birds, the presence of sanitary filters and the practical change of clothing is not associated with the presence of the Newcastle virus; the risk decreases in ducks compared to however. Likewise, the source and management variable is not considered statistically associated, p is greater than 0.05. The farms included in the study have bad biosecurity practices, birds of different species and ages coexist in the same facilities. The management system corresponds to the traditional one where the animals are kept in grazing conditions, the feeding is based mainly on concentrate, food leftovers and corn, likewise, the animals do not have veterinary technical assistance. It is necessary to strengthen the breeding of backyard birds by establishing vaccination plans, epidemiological surveillance, constant training, on management, as well as sanitary measures especially Newcastle disease that decimates the populations of backyard birds in rural areas, putting safety at risk food of the peasants of the area. Keywords: seroprevalence. Newcastle, backyard, ELISA.
