From: Interspecies and intraspecies transmission of triple reassortant H3N2 influenza A viruses
Cartoon representing the amino acid changes at the HA molecule of the A/turkey/Ohio/313053/04 H3N2 virus, that occurred upon replication and transmission of the virus between turkeys and pigs. Red: receptor binding domain (RBD). Yellow: the change at residue 190 that occurred upon transmission of the virus from turkeys to pigs. Violet: the change at residue 246 that occured in two of the inoculated pigs and one of the contact turkeys with inoculated pigs.
