Abstract
Abstract: The first influenza pandemic of this century was declared in April of 2009, with the emergence of a novel H1N1 influenza A virus strain (H1N1pdm). Understanding the evolution of H1N1pdm strains within the South American region is essential for studying global diversification, emergence and resistance, as well as determining vaccine efficacy. In order to gain insight into these matters, phylogenetic analysis was performed using 29 hemagglutinin (HA) gene sequences from H1N1pdm strains isolated in South America. The results of these studies revealed that clade 7 was the dominant H1N1pdm lineage in South America. None of the strains isolated in South America clustered together with the 2010 H1 vaccine strain. Amino acid substitutions P100S, S220T and I338V were found in almost all HAs of South American H1N1pdm strains.
