TARGETED SURVEILLANCE OF AVIAN INFLUENZA IN WILD BIRDS USING DOMESTIC DUCKS (CAIRINA MOSCHATA) AS SENTINELS

A targeted surveillance method was applied for the early detection of the Avian Influenza Virus (AIV) in the wild birds of the Puerto Viejo’s wetlands in Cañete, Lima, Peru. Twelve 16-week-old domestic ducks of the Muscovy variety (Cairina moschata) were used as sentinels. The ducks, with negative serology and virus isolation to AIV and Newcastle disease, were introduced to the surrounding areas of the wetlands for 70 days during the 2006 winter in order to interact with the resident wild birds. A preliminary identification of the wild bird species present during the study period was done and the interaction degree between both bird populations was subjectively determined. Health status of sentinel birds was assessed by regular clinical examinations as well as cloacal swab and blood samplings, both for virus isolation and for the detection of antibodies against the AIV by the agar gel immune-diffusion (AGID) test. Throughout the study no antibodies were detected, neither was the AIV isolated. The negative results obtained in the evaluations that were performed under the conditions of the study and the time it lasted suggest the absence of the IVA and its horizontal transmission in the populations of wild birds of the Puerto Viejo’s wetlands.

Se aplicó un método de vigilancia dirigida para la detección temprana del virus de influenza aviar (VIA) en aves silvestres de los Humedales de Puerto Viejo, provincia de Cañete, departamento de Lima, Perú. Se usaron como centinelas a 12 patos domésticos de 16 semanas de edad, variedad Muscovy (Cairina moschata), negativos por serología y aislamiento viral a VIA y enfermedad de Newcastle, los cuales fueron introducidos a las zonas que circundan los humedales por un periodo de 70 días durante el invierno del 2006, con el fin de que interactúen con las aves silvestres residentes. Se realizó una identificación preliminar de las especies de aves silvestres presentes durante el estudio y se determinó subjetivamente el grado de interacción entre ambas poblaciones de aves. Se evaluó el estado sanitario de las aves centinelas mediante exámenes clínicos periódicos, muestreos de hisopados cloacales y sangre, tanto para aislamiento viral como para la detección de anticuerpos contra los VIA por la prueba de Inmunodifusión en Agar. No se detectaron anticuerpos ni se aisló VIA. Los resultados negativos obtenidos en las evaluaciones realizadas bajo las condiciones y tiempo que duró el estudio sugieren la ausencia del VIA y su transmisión horizontal por las poblaciones de aves silvestres de los humedales de Puerto Viejo.
