Avian Adenoviruses: Distribution of Infection in Commercial Flocks of Fowls in Argentina

Abstract
Group-specific avian adenovirus antibodies were surveyed in broiler, layer and breeder chickens in 3 poultry-producing areas of Argentina: north, middle and south. The method used was the agar double-immunodiffusion test. Of the flocks examined, 89% had antibodies to avian adenovirus, with the percentages higher in layers and breeders than in broiler chickens. A close relation was found between poorer hygienic condition and high adenovirus antibodies values.
