禽星狀病毒（avian astrovirus，從廠AAstV）屬于星狀病毒科，包含多種(zhǒng)亞型們高，可以引發(fā)禽腎炎、鴨肝炎以及現火火雞腹瀉等多種(zhǒng)疾病，禽類感染後(hòu)表現生暗員長(cháng)發(fā)育遲緩、産蛋下還線降，嚴重時(shí)可導緻死亡，給養殖業時化造成(chéng)一定的損失。此外，AAstV具有感染人的潛在風險。著件目前AAstV的緻病機理暫不清楚，隻有火雞星狀病毒引發(fā)腸炎的頻用緻病機制可作爲參考。許多方法已用于AAstV檢測，如電鏡檢測、酶聯免疫少化吸附試驗、細胞培養和病毒分離以及分子技術檢測等。AAstV亞型較多，嗎你疫苗和藥物研發(fā)存在較大難新兵度，給該病防治帶來一定的挑戰。本文圍繞AAstV的病原學(xué子畫)、國(guó)内外流行情況、感染後(hòu)臨床症狀及緻病機制事事以及檢測方法和控制措施等進(jìn)行了綜述，以期爲後秒草(hòu)期進(jìn)一步研究提供參考。
