Phylogenetic analysis of H1N1 sequences from pandemic XXXX during 2009 in India.

@entity1 @entity1707 @entity778 @entity689 @entity11317 @entity281 @entity166
Since April 2009, a serious @entity281 has been rapidly spread across the world. These @entity281 are caused due to the novel @entity1707 origin @entity778 and hence these are commonly called as " @entity1707 Flu". This new virus is the reassortment of avian, @entity1 and @entity1707 influenza viruses and thus it has a unique genome composition. There are 16 different types of hemagglutinin (HA) and 9 different types of @entity689 (NA) that can be genetically and antigenetically differentiated. The first @entity11317 isolated from @entity1707 was of the H1N1 subtype and these viruses have been reported to cause @entity281 in @entity1707 in many countries. The outbreak of this virus has been transmitted from @entity1707 to @entity1 . This new reassorted (exchange of genes) virus which is the cause of 2009 pandemic @entity281 has the ability to spread from @entity1 to @entity1 . This spread of @entity281 should be brought to an end. In this study, a phylogenetic analysis of the nucleotide sequences of the RNA segments of @entity1 H1N1 viruses was carried using MEGA version 4.0 to demonstrate the route map of @entity281 to India. Phylogenetic analysis of the sequences from India, published in Influenza Virus Resource (a database that integrates information gathered from the Influenza Genome Sequencing Project of the @entity166 ( @entity166 ) and the genbank of the (NCBI)) was retrieved and used for the analysis. The results showed that the various segments of the Indian isolates clustered well with the sequences from American, Asian and European countries and thus indicating the transmission of viruses from these places to India.
