Influenza A virus has a wide range of hosts. It has not only infected human, but also been reported interspecies transmission from humans to other animals, such as pigs, poultry, dogs and cats. However, prevalence of A (H1N1) pdm09 influenza virus infections in cats in northeastern China is unknown. Therefore, the prevalence of A (H1N1) pdm09 influenza virus infections was performed among cats in northeastern China in this study.
Of all samples in this study, the overall seroprevalence of pandemic (H1N1) 2009 infection in cats was 21% (240/1140). It also showed a higher prevalence rate of pandemic(H1N1) 2009 infection in pet cats (30.6%) than roaming cats (11%) based on NT. In addition, the results also showed a trend of difference in term of species of cats and it was statistically significant.
This is the first survey on the seroprevalence of pandemic (H1N1) 2009 infection among cats in northeastern China. This study has observed a relatively high seroprevalence of pandemic (H1N1) 2009 among different cat populations in northeastern China, similar seroprevalence studies should be conducted elsewhere.
甲型流感病毒宿主范围广泛。它不仅感染人类，还曾有过跨物种传播的报道，例如从人类传播至猪、禽类、犬和猫等其他动物。然而，目前尚不清楚甲型（H1N1）pdm09 流感病毒在我国东北地区猫群中的流行情况。因此，本研究旨在调查我国东北地区猫群中甲型（H1N1）pdm09 流感病毒的感染情况。
在本研究的所有样本中，猫群中流行（H1N1）2009 感染的总体血清阳性率为 21%（240/1140）。基于 NT，宠物猫（30.6%）的流行（H1N1）2009 感染率明显高于流浪猫（11%）。此外，研究结果还显示不同品种猫之间存在感染率差异的趋势，且具有统计学意义。
这是我国东北地区首次针对猫群中流行（H1N1）2009 感染的血清阳性率进行的调查。本研究观察到我国东北地区不同猫群中流行（H1N1）2009 的血清阳性率相对较高，因此应在其他地区开展类似的血清阳性率研究。
