interspecies transmission and limited persistence of low pathogenic avian influenza genomes among alaska dabbling ducks.the reassortment and geographic distribution of low pathogenic avian influenza (lpai) virus genes are well documented, but little is known about the persistence of intact lpai genomes among species and locations. to examine persistence of entire lpai genome constellations in alaska, we calculated the genetic identities among 161 full-genome lpai viruses isolated across 4 years from five species of duck: northern pintail (anas acuta), mallard (anas platyrhynchos), american green-winged teal (anas ...201121964597
mx gene diversity and influenza association among five wild dabbling duck species (anas spp.) in (myxovirus-resistant) proteins are induced by interferon and inhibit viral replication as part of the innate immune response to viral infection in many vertebrates. influenza a virus appears to be especially susceptible to mx antiviral effects. we characterized exon 13 and the 3' utr of the mx gene in wild ducks, the natural reservoir of influenza virus and explored its potential relevance to influenza infection. we observed a wide range of intra- and interspecies variations. total nucleotide ...201020621205
