Abstract

The 2 predominant circulating subtypes of influenza A virus in the dog population, equine-origin H3N8 and avian-origin H3N2, constitute a potential zoonotic risk. We determined the prevalence of influenza A antibodies in 496 dogs in Poland and found 2.21% of sera positive by commercial ELISA. Hemagglutination inhibition (HI) assays indicated 7.25% of sera positive using equine H3N8, swine H3N2, and pandemic H1N1 antigens, with the most frequently detected immune response being to H3N2. Considering interspecies transfer, reassortment ability, and close contact between dogs and humans, infections of dogs with influenza A virus should be monitored.

摘要

犬类群体中两种主要的甲型流感病毒循环亚型,马源H3N8和禽源H3N2,构成了潜在的人畜共患病风险。我们测定了波兰496只犬中甲型流感抗体的流行情况,发现2.21%的血清通过商业ELISA检测呈阳性。血凝抑制(HI)试验表明,使用马H3N8、猪H3N2和大流行H1N1抗原时,7.25%的血清呈阳性,最常检测到的免疫反应是针对H3N2。考虑到跨物种传播、重配能力以及犬与人类之间的密切接触,应对犬感染甲型流感病毒的情况进行监测。
