Of these specimens, 78 (5.7%) were confirmed by hemagglutinin inhibition (HI) assay to be positive for H9, and sequencing data for 55 virus isolates were generated.
With 18 hemagglutinin varieties and 11 types of neuraminidase -- most carried by birds -- there are lots of potential combinations.
The objective of the study was to evaluate diagnostic effectiveness of IAVchip DNA microarray in differential detection of 16 hemagglutinin and 9 neuraminidase IAV subtypes as compared to virus isolation in chicken embryos, real-time PCR, and RT-PCR.
"It looks like these antibodies need to cross-link two hemagglutinins to have maximum effect," said Wilson.
A fourth change in hemagglutinin may affect how well the virus can fuse with cells in ferret--and presumably human--hosts.

Hemagglutinin (HA) of avian influenza virus strains shows preferential binding to SA[alpha]2,3 receptors, which partially accounts for the reduced ability of avian influenza strains to establish infections in humans (3).
In parallel to IgG detection for control groups, we also evaluated IgG levels against seasonal influenza virus hemagglutinins H1 and H3 by ELISA of the 15 paired serum samples (Figure 3, panel A).
