Fig. 1.
HIV Pol diversity and consensus amino acid comparison in Saskatchewan and elsewhere in Canada/USA.
Panel a: Unrooted maximum-likelihood phylogenies inferred from 1144 and 6517 HIV subtype B sequences collected between 2000–2016 from Saskatchewan (‘SK’; green) and other areas of Canada and the USA (’CA/US’; black) respectively, depicted on the same distance scale. Panel b: Top: Percentage of sequences in Saskatchewan and CA/US datasets that fall within a cluster. Bottom: cluster size distributions in Saskatchewan and CA/US (expressed as a proportion of the total number of clusters in each dataset). Panel c: Consensus Pol amino acid sequences in CA/US versus Saskatchewan, with the 9 differences highlighted in yellow.
