Summary of the changes found in Junín virus proteins. A. S RNA; the N and GPC ORFs are shown as arrows, indicating the translation sense. The strains used for the comparison are shown on the left side. The parts of GPC are marked below the diagram. Amino acid changes among the strains (XJ#13, XJ#17, XJ#34, XJ#39, XJ#44, XJ#48 and Candid#1) are drawn as lines above the gene, followed by the identity of the change and its position. Variations among the field strains (XJ#13, Romero, IV4454 and MC2) are drawn as lines below the gene. B. Relative frequency of mutation for the different types: black is for type-1and grey for type-2.
