ABSTRACT

Objetivo. Evaluar la dinámica serológica contra el virus de bronquitis infecciosa aviar y su relación con la presentación y/o antecedentes de signos clínicos y hallazgos patológicos, bajo condiciones de campo. Materiales y métodos. Se realizó un muestreo al azar en dos fases, en pollo de engorde y reproductoras de granjas del Departamento de Cundinamarca. En la primera fase se tomó muestra de sangre a un total de 224 aves, distribuidas en 7 granjas. En la segunda fase, realizada 20 días posteriores al primer muestreo, se tomó una segunda muestra al mismo número de aves empleadas inicialmente. Las muestras de los sueros obtenidos se emplearon para la realización del inmunoensayo ligado a enzima (ELISA), diseñado para detectar anticuerpos frente al virus de la bronquitis infecciosa aviar en suero sanguíneo. Resultados. Se obtuvo que del total de las granjas analizadas el 85.72% mostró reactividad serológica al virus de la Bronquitis Infecciosa aviar (VBIA), con correlación ante la presencia de los signos clínicos o antecedentes respiratorios en granja.


Objective. Evaluate the serological dynamics against avian infectious bronchitis virus and its relationship with the presentation and / or a history of clinical signs and pathological findings, under field conditions. Materials and methods. A random sampling was conducted in two phases, in broiler and breeder farms located in the Department of Cundinamarca. In the first phase blood sample were taken from a total of 224 birds, distributed over the 7 farms. In the second phase, carried out 20 days after the first, a second sample was collected from the same number of birds used in the first phase. The serum samples were used to carry out the enzyme linked immunoassay (ELISA) intended to detect antibodies against avian infectious bronchitis virus in blood serum. Results. As a result it was found that from the total farms analyzed the 85.72% showed serologic reactivity against Avian Infectious Bronchitis Virus (AIBV) that correlated to the presence of clinical signs or previous history of respiratory disease in the farm.
