Evidencia serológica de infección por metapneumovirus en aves comerciales de la provincia de Buenos Aires y Entre Ríos (Argentina)

A serological investigation was made in commercial flocks of Buenos Aires and Entre Rios provinces by ELISA technique. The serological evidence of metapneumovirus infection was determined by testing 933 serum samples from broilers flocks and broiler-breeders between March of 2007 and October of 2008. 169 of these samples were positives. The result of this study was analyzed by statistics methods. The conclusion shows a better possibility to obtain positive results in broiler-breeders than in broilers flocks. This is the first report of avian metapneumovirus serological evidence in the Argentinian Republic.
