Figure 1.

The deduced multiple the deduced sequence alignment of amino acids encoded by the S2 genes of viruses isolated from four EIAV_LN40-infected horses. The sequences of all the viral clones were aligned to the consensus sequence (con) of EIAV_LN40, shown at the top. Only the amino acid residues that are different from the consensus sequence of EIAV_LN40 are indicated. The dots indicate residues identical to the consensus sequence. The numbers in the left column in each sequence indicate the number of a specific sequence in the total detected clones of each sample. The red letters denote the stable substitutions.
