Phylogenetic tree of HRSV-A, constructed with a partial G-protein gene (ranging from nucleotide coding sequence 634–890 of reference strain Long, Genbank M17212), comparing 24 HRSV worldwide sequences and 11 Paraguayan isolates. Genotypes GA1–GA7, NA1, NA2, SAA1, and ON1 are grouped and indicated in parentheses. Each sequence is indicated with its corresponding name and GenBank accession number. Paraguayan isolates are labeled according to year of isolation: 2010 (■), 2011 (▲), 2012 (♦), and 2013 (●). Bootstrap values greater than 70% are shown at branch nodes. Branch distance is indicated by a scale bar at the bottom of the tree.
