Figure 4From: Comparative full length genome sequence analysis of usutu virus isolates from AfricaML phylogeny based on the polyprotein of the Japanese encephalitis (JE) group of flaviviruses. The position of the Usutu subtype CAR_1969 is indicated by an asterisk (*). For clarity, bootstrap values ≥ 75% are given for those nodes leading to primary clades only. The tree is rooted based on the position of the JEV group relative to the rest of the Flaviviridae in a preliminary ML tree (data not shown). The branch lengths and scale bar are drawn to a scale of nucleotide substitutions per site.Back to article page
