Astrovirus is a common cause of enteritis in humans and domestic animals. Here we report the detection of turkey astrovirus type 1 (TAstV-1) and chicken astrovirus (CAstV) in avian farms. Sixty fecal sample pools (five or six birds of the same flock), from chickens without apparent clinical symptoms of enteric disease from farms located in six Brazilian states, were screened by an ORF1b PCR, followed by nucleotide sequencing of amplified products and phylogenetic analysis. Six samples tested positive for TAstV-1 and two for CAstV. One positive sample of each detected virus (TAstV-1 and CAstV) had the complete ORF2 sequenced. Data for the ORF2 sequence indicate that Brazilian TAstV-1 was divergent from TAstV-1 (United States), previously described infecting turkeys, and Brazilian CAstV clustered together with the U.K. group, subgroup B-II, associated with enteritis and growth retardation in chicks. This study provides updated information about CAstV and the first report of detection of TAstV-1 in Brazilian chickens, supporting the diagnostic of enteritis and epidemiologic surveillance in poultry health.
