Direct electron microscopy was used to identify virions of infectious laryngotracheitis in lysed tracheal cells and of fowlpox in scabs and exudates from natural cases. Rapid identification of avian adenovirus and infectious laryngotracheitis by gel diffusion was possible using antigens prepared by simple distilled-water lysis of infected cell cultures. Precipitin lines were often visible within 5 hours.
