Technical Abstract: This study investigated the genetic diversity of enteric viruses circulating in poultry. Intestinal samples collected from numerous commercial turkey and broiler flocks from different regions of the United States during 2005, were examined for the presence of astrovirus, rotavirus, reovirus and coronavirus by RT-PCR, and for adenoviruses by PCR. Viruses, predominantly astrovirus and rotavirus, were found in samples collected from flocks with enteritis and stunting as well as from healthy flocks. Comparison of these viruses was performed by phylogenetic analysis. Four clearly different astroviruses are circulating in poultry: Turkey Astrovirus 1 (TAstV-1), Turkey Astrovirus 2 (TAstV-2), Avian Nephritis Virus (ANV) and a novel Chicken Astrovirus (CAstV). Rotaviruses were widely distributed in chickens and turkeys.
