[h=1]Sparse serological evidence of H5N1 avian influenza virus infections in domestic cats, northeastern China.[/h] Zhou P[SUP]1[/SUP], He S[SUP]1[/SUP], Sun L[SUP]2[/SUP], Jia K[SUP]1[/SUP], Fu C[SUP]1[/SUP], Sun Y[SUP]1[/SUP], He H[SUP]1[/SUP], Tu L[SUP]1[/SUP], Ning Z[SUP]1[/SUP], Yuan Z[SUP]1[/SUP], Wang H[SUP]1[/SUP], Li S[SUP]1[/SUP], Yuan L[SUP]3[/SUP].

[h=3]Abstract[/h] Today the cross-species transmission of avian influenza viruses (AIV) are a great concern. A number of AIV strains are now enzootic among poultry, with H9N2 and highly pathogenic H5N1 AIV strains prevalent in China. H5N1 strains have been recognized to infect zoo and domestic feline species. In this serological study we sought to examine evidence that H5N1 strains have infected domestic cats in northeastern China. In 2013, we conducted a cross-sectional serological study of 916 healthy cats in Heilongjian, Jilin, and Liaonin Provinces. Sera were screened with a hemagglutinin inhibition (HI) assay and seropositive specimens (HI ≥ 1:20) were further evaluated with a microneutralization (MN) assay against a clade 2.3.2 H5N1 AIV, a H9N2 AIV, A(H1N1)pdm09, and a canine H3N2 virus. While ∼2% of cats had elevated HI assays against H5N1, no elevations were confirmed (MN ≥ 1:80). These data serve as baseline for future surveillance for AIV infections among domestic cats. Conducting such surveillance seems important for geographical areas recognized as endemic for AIVs. This is especially true for countries such as China where domestic cats and poultry are often in close contact.
