Group-specific avian adenovirus antibodies were surveyed in broiler, layer, and breeder chickens in three 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.
