Abstract

Although birds infected with avian polyomavirus (APV) subclinically could be a source of infection, no epidemiological studies of APV in psittacine birds have been reported in Japan. In the present study, we investigated subclinical morbidity rate of APV in imported and domestically bred psittacine birds by polymerase chain reaction (PCR). Of 402 live birds from which blood or feather samples were taken between April, 2003 and March, 2004, 11 (2.7%) were found to be APV positive. The DNA sequences of the APV t/T antigen region were determined for five APV-positive randomly selected samples and were found to be conserved.

摘要

虽然亚临床感染禽多瘤病毒（APV）的鸟类可能是感染源，但日本尚未有关于鹦鹉类鸟中APV的流行病学研究报道。在本研究中，我们通过聚合酶链反应（PCR）调查了进口和国内养殖的鹦鹉类鸟中APV的亚临床发病率。在2003年4月至2004年3月期间采集血液或羽毛样本的402只活鸟中，有11只（2.7%）被发现APV呈阳性。对随机选择的5个APV阳性样本测定了APV t/T抗原区域的DNA序列，发现它们具有保守性。
