| dc.description.abstract | The neuraminidase (NA) gene sequences of four Indian equine influenza viruses (EIVs) isolated from epizootic in2008and2009wereanalyzed.Thephylogeneticrelationship and selection pressure of NA genes were established in comparison to other EIVs circulating worldwide along with the domains and motifs of the encoded protein to find out the significance of mutational changes. Among Indian isolates, two amino acid (aa) changes each in Mysore/12/08 (Asn67Tyr & Asp396Gly), Gopeshwar/1/09 (Ile49Val & Asp396Gly), and Uttarkashi/1/09 (Ile49Val & Asp396Gly) isolates were observed in respect to Jammu-Katra/06/08 isolate. Amino acid (aa) sequence analysis also revealed five consistent aa residue changes viz, Gly/Arg40Glu, Tyr66His, Val191Ile, Val209Ile and Asp235Asn in Asian including Indian isolates, Spain/07 and Spain/09 isolates in comparison to other EIVs circulating worldwide.Thetopologyofthephylogenetictreerevealedthat the Indian, Chinese, Mongolian and Kazakhstan isolates togetherformedasubgroupwithYokohama/10isolate.Spain/07& Spain/09isolatesshowedclosestclusteringwithAsianisolates. Thisindicatesthatnon-synonymousmutationsinAsianisolates with temporal pattern originating from Spain/07, led to the subgroup of the Asian isolates within Florida clade 2 sublineage. The analysis of the predicted secondary structure has not shown any significant difference in the NA proteins of all Indian isolates. Fixed-effects likelihood (FEL) analysis of the selection pressure revealed three codons (43, 355 & 434) under positive selection pressure. The overall evolutionary changes(xvalue)of3.4indicatesNAgenetobeunderstrong selection pressure. Further, seven putative N-glycosylation siteswereobservedintheNAprotein.Themappingofspecific aachanges,theirmutationalandfunctionalanalysisneedtobe carriedouttoascertaintheirroleinpathogenecityofthevirus | en_US |
