Figure 3.
Evolutionary signature of the FMDV serotype C generated using 149 partial FMDV genome sequences encoding the VP1 capsid region. Left panel, maximum-likelihood topology where internal nodes with bootstrap values of ≥75 are coloured in red; right panel, matrix of pairwise evolutionary distances. Topotypes with their subtypes are denoted (green panels). The viruses labelled as C/ETH/6/2005 and C/ETH/7/2005 were submitted to the WRLFMD in 2005 from samples collected in 1983. There are two slightly different viruses called C3/Indaial/Brazil/1971, which differ in cell culture passage history and by about 4% in VP1 (Ouldridge, July 1988, pers. comm.).
