Amino acid differences between epidemic (Ep) and non-epidemic (NEp) SLEV strains and the polyprotein conservation profile.

<p>The horizontal bar represents the SLEV polyprotein. (<b>A).</b> Black vertical lines represent residues (in one letter code) that differed between strains studied (CbaAr-4005 (Ep) and 79V-2533 (NEp)). In grey, the non-conservative changes and their respective individual protein positions are highlighted. (<b>B).</b> Polyprotein homology profile for all studied SLEV strains. The light pink areas show the more conserved regions while in the less conserved zones are in blue. (<b>C).</b> Individual protein homology profile for all studied SLEV strains. The Y axis shows the Relative Homology (RH) between 0 and 1 while the X axis shows the residue position. In each protein profile, the zones that show an RH value lower than 0.8 are boxed.
