Abstract

Four avian pneumovirus (APV) isolates from chickens clinically diagnosed with swollen head syndrome were genetically characterized as to the subtypes of the virus in Japan. The results of reverse transcriptase-polymerase chain reactions based on subtype-specific primers and direct sequence analysis of G genes indicated subtypes A and B but not C or D of APV were present in Japan. Several routes or sources are conceivable for APV to invade into Japan.

摘要

对从临床上诊断为肿头综合征的鸡中分离出的4株禽肺病毒（APV）进行基因特征分析，以确定其在日本的病毒亚型。基于亚型特异性引物的逆转录聚合酶链反应结果以及G基因的直接序列分析表明，日本存在APV的A和B亚型，但不存在C或D亚型。APV侵入日本可能有几种途径或来源。
