We detected three chicken astrovirus strains in 4-day-old broiler chickens with high mortality and visceral gout and one strain from 150-day-old hens without clinical symptoms in Saga prefecture, Japan. Phylogenetic analysis based on ORF2 amino acid sequences revealed that the strains from the visceral gout cases belonged to subgroup Bi, and the strain from hens without clinical symptoms belonged to subgroup Aiii. Our study showed that CAstV had infiltrated into Saga prefecture, Japan. This is the first report of CAstV in Japan.
我们在日本佐贺县的高死亡率和内脏痛风 4 日龄肉鸡中检测到了 3 株禽星状病毒株，在没有临床症状的 150 日龄母鸡中检测到了 1 株禽星状病毒株。基于 ORF2 氨基酸序列的系统进化分析表明，内脏痛风病例中的毒株属于亚群 Bi，而无临床症状母鸡中的毒株属于亚群 Aiii。我们的研究表明，CAstV 已经渗透到日本佐贺县。这是日本首次报道 CAstV。
