S1 Table. H gene sequence isolates used in determining the phylogenetic relationship of
canine distemper virus. The accession number, host species, year and country of origin
(when available) are indicated for each strain. South African strains isolated for this study indicated
with asterisk ( ).
S2 Table. Residues at amino acid sites of the SLAM and nectin-4 cell binding regions on
the canine distemper virus H-protein, arranged in geographical lineages and host species
(domestic dog, wild canid and non-canid). The accession number, host species, year and
country of origin are indicated for each strain. South African strains isolated for this study
indicated with asterisk ( ). Identical amino acids are indicated with a dash (-), varying amino
acids are indicated by single letter amino acid codes.
