La aplicación de vacunas vivas a través del alimento se ha postulado como un método eficaz para el control de la enfermedad, siendo ideal para reducir la presentación de signos clínicos y mortalidad en aves de traspatio; sin embargo, en Colombia el uso de esta estrategia es pobremente entendido. El presente estudio determinó la viabilidad de dos virus de baja virulencia del NDV (cepas VH y La Sota) mezclados con arroz y maíz bajo diferentes tipos de preparación y evaluó indicadores de respuesta inmune humoral e innata en aves luego de vacunarlas por vía oral. El título viral fue determinado por el método de Reed & Muench. Luego se realizó RT-qPCR para cuantificar la carga viral. Se obtuvieron resultados más consistentes mezclando la cepa VH con maíz cocido, por lo que la cepa LaSota y todos los otros vehículos fueron descartados del estudio. Posteriormente, 160 pollos machos (Babcock) fueron divididos aleatoriamente en cuatro grupos: un control negativo, y tres grupos vacunados (vía ocular, agua de bebida y vía maíz). Las aves fueron inmunizadas al día 28 de edad con la cepa VH por las vías señaladas y se tomaron sueros al día 1, 15 y 25 de edad y a los 7, 14 y 21 días post-vacunación para su evaluación por IH. Se tomaron parámetros productivos como peso y conversión acumulada. Se cuantificó la excreción viral y la expresión relativa de IL-6 e IFN-γ los días 2 y 4 post-vacunación en macerados de bazo por RT-qPCR. Finalmente, se calcularon índices de peso de órganos linfoides y se tomaron muestras de tejido digestivo, linfoide y respiratorio para evaluación histopatológica. Los resultados indicaron que la cepa VH mostró más estabilidad y el maíz cocido fue el candidato como vehículo. En cuanto a los títulos de anticuerpos hubo diferencias estadísticas significativas entre las vías de administración al día 7, pero no a los 14 y 21 días post-vacunación. No hubo diferencias en los índices linfoides, pero se observaron diferencias en el grado de lesión histopatológica en cornetes y laringe entre los grupos vacunados y el grupo control los días 2 y 4 post-vacunación. Se evidenció excreción viral en los grupos vacunados comparado con el control, siendo más alta en los grupos ocular y agua al día 2 post-vacunación y en el grupo maíz al día 4 post-vacunación. La expresión de IL-6 se evidenció temprano, pero la expresión de IFN-γ se evidenció solo hasta el día 4 post-vacunación. Este estudio mostró que la vía oral a través del alimento activa la respuesta inmune y que el maíz cocido y la cepa VH podrían ser una estrategia para un programa de control del NDV en aves de traspatio en Colombia. (Texto tomado de la fuente).Newcastle disease virus (NDV) is one of the most serious respiratory problems causing significant economic losses to poultry producers. The application of live vaccines through food has been postulated as an effective method to control the disease, being ideal to reduce the presence of clinical signs and mortality in backyard birds; however, in Colombia the use of this strategy is poorly understood. The present study determined the viability of two low pathogenic NDV viruses (VH and La Sota strains) mixed with rice and corn under different types of preparation and evaluated both of humoral and innate immune responses in birds after oral vaccination. The viral titer was determined by the Reed & Muench procedure. Then RT-qPCR was performed to quantify viral load. Consistently results were obtained mixing VH strain with cooked corn, so that LaSota strain and the other vehicles were discarded. Subsequently, 160 male chickens (Babcock) were randomly divided into four groups: a negative control, and three vaccinated groups (ocular route, drinking water and corn). The birds were immunized at day 28 of age with the VH strain by the indicated routes and sera were taken at days 1, 15 and 25 of age and at 7, 14 and 21-days postvaccination for evaluation by HI. Productive parameters such as weight and accumulated conversion were taken. Viral shedding and relative expression of IL-6 and IFN-γ were quantified on days 2 and 4 post-vaccination in spleen by RT-qPCR. Finally, lymphoid organ weight indices were calculated and digestive, lymphoid and respiratory tissue samples were taken for histopathological evaluation. The results indicated that the VH strain showed more stability and cooked corn was the candidate as a vehicle. Regarding antibody titers, there were statistically significant differences between administration routes on day 7, but there were no differences at 14 and 21 days post-vaccination. There were no differences in lymphoid indices, but differences in larynx and turbinates histopathological lesion scores were seen on days 2 and 4 post-vaccination. Cloacal viral shedding was evident in vaccinated groups compared to the control being higher in eye and water groups on day 2 and in corn group on day 4 post-vaccination. IL-6 expression was evidenced early, but IFNγ expression was evidenced only up to day 4 post-vaccination. This study showed that the oral route through food activates the immune response and that cooked corn and the VH strain could be a strategy to a NDV control program in backyard poultry in Colombia.Federación Nacional de AvicultoresFondo Nacional AvícolaIncluye anexosMaestríaMagíster en Salud Animal o Magíster en Producción AnimalMicrobiologia e Inmunologiaxix, 109 páginasapplication/pdfspaUniversidad Nacional de ColombiaBogotá - Medicina Veterinaria y de Zootecnia - Maestría en Salud y Producción AnimalDepartamento de Ciencias Para La Salud AnimalFacultad de Medicina Veterinaria y de ZootecniaBogotá, ColombiaUniversidad Nacional de Colombia - Sede Bogotá630 - Agricultura y tecnologías relacionadas::636 - Producción animalNewcastle diseasePoultry - diseasesPoultry virus diseasesEnfermedad de NewcastleAves de corral - enfermedadesVirosis en las aves de corralRT-qPCRInhibición de la hemaglutinaciónMaízVirus de la enfermedad de NewcastleVacuna vivaAdministración oral en alimentoCornHemagglutination inhibitionNewcastle disease virusLive attenuated vaccineqRT-PCROral administration in foodViabilidad de cepas vacunales del virus de la enfermedad de Newcastle en arroz o maíz y respuesta inmune inducida en aves vacunadas vía alimentoViability of Newcastle disease virus vaccine strains in rice or corn and immune response induced in poultry vaccinated via feedTrabajo de grado - Maestríainfo:eu-repo/semantics/masterThesisinfo:eu-repo/semantics/acceptedVersionTexthttp://purl.org/redcol/resource_type/TMAbdi, R.
