    In late 2011, an A(H3N8) influenza virus infection resulted in the deaths of 162 New England harbor seals. Virus sequence analysis and virus receptor binding studies highlighted potential markers responsible for mammalian adaptation and a mixed receptor binding preference (S. J. Anthony, J. A. St Leger, K. Pugliares, H. S. Ip, J. M. Chan, Z. W. Carpenter, I. Navarrete-Macias, M. Sanchez-Leon, J. T. Saliki, J. Pedersen, W. Karesh, P. Daszak, R. Rabadan, T. Rowles, W. I. Lipkin, MBio 3:e00166-00112, 2012, http://dx.doi.org/10.1128/mBio.00166-12). Here, we present a detailed structural and biochemical analysis of the surface antigens of the virus. Results obtained with recombinant proteins for both the hemagglutinin and neuraminidase indicate a true avian receptor binding preference. Although the detection of this virus in new species highlights an increased potential for cross-species transmission, our results indicate that the A(H3N8) virus currently poses a low risk to humans.
