TLDR
Using consensus degenerate RT-PCR, a novel influenza A virus is identified in a flat-faced fruit bat from Peru, indicating that bats constitute a potentially important and likely ancient reservoir for a diverse pool of influenza viruses.Abstract:
Aquatic birds harbor diverse influenza A viruses and are a major viral reservoir in nature. The recent discovery of influenza viruses of a new H17N10 subtype in Central American fruit bats suggests that other New World species may similarly carry divergent influenza viruses. Using consensus degenerate RT-PCR, we identified a novel influenza A virus, designated as H18N11, in a flat-faced fruit bat (Artibeus planirostris) from Peru. Serologic studies with the recombinant H18 protein indicated that several Peruvian bat species were infected by this virus. Phylogenetic analyses demonstrate that, in some gene segments, New World bats harbor more influenza virus genetic diversity than all other mammalian and avian species combined, indicative of a long-standing host-virus association. Structural and functional analyses of the hemagglutinin and neuraminidase indicate that sialic acid is not a ligand for virus attachment nor a substrate for release, suggesting a unique mode of influenza A virus attachment and activation of membrane fusion for entry into host cells. Taken together, these findings indicate that bats constitute a potentially important and likely ancient reservoir for a diverse pool of influenza viruses.read more

Phylogenetic Tree and Antiviral Resistance Analysis of Neuraminidase Gene of Influenza A Virus in H1N1 Strains Found in 2010 and 2013
TL;DR: The analysis of phylogenetic tree revealed some diverse strains of influenza A virus indicated the antigenic drift and antigenic shift and similar types of amino acids near the reported mutated positions that may reduce sensitivity to Neuraminidase.
The molecular basis of influenza virus antigenic change
TL;DR: It was shown that the ability of key substitutions to cause antigenic change is largely independent of the amino acid context, and that substitutions similar to those that caused antibody escape in the past are potentially important for future antigenic changes of the influenza viruses responsible for the 2009 influenza pandemic.
