A sero-epidemiological survey of human and equine H3 influenza A virus infections in dogs and cats using the hemagglutination inhibition (HI) and neuraminidase inhibition (NI) tests was conducted. Serum samples were collected from 582 dogs and 237 cats in Japan during the periods 2002-2008 and 1997-2008, respectively. Although no HI antibodies against equine H3 virus were detected, 9 (3.8%) from cats and 12 (2.1%) from dogs were HI-positive against human H3 virus. Only one serum each from dogs and cats was NI-positive against N2 virus. These findings suggest that although equine H3 influenza virus infections have not been prevalent in companion animals, human H3N2 influenza A virus infections have occurred in dogs and cats in recent years in Japan.
利用血凝抑制（HI）试验和神经氨酸酶抑制（NI）试验，对犬猫感染人源和马源甲型H3流感病毒进行了血清流行病学调查。分别于2002年至2008年及1997年至2008年期间，从日本的582只犬和237只猫采集了血清样本。虽然未检测到针对马源H3病毒的HI抗体，但猫中有9份（3.8%）、犬中有12份（2.1%）针对人源H3病毒的HI检测呈阳性。犬猫各只有一份血清针对N2病毒的NI检测呈阳性。这些结果表明，虽然马源H3流感病毒感染在伴侣动物中并不普遍，但近年来日本的犬猫中发生了人源甲型H3N2流感病毒感染。
