Figure 2.

Homology between Gag amino acid sequences derived from EFVeca isolates available in GenBank and naturally infected horses from this work, sequences were devoid of primers: (A) pairwise percent identity of Gag amino acid sequences, the intensity of the color is correlated with pairwise percent identity; (B) alignment of Gag protein sequences with predicted antigenic regions indicated by red arrows with numbers reflecting the scores of prediction. Green bar corresponds to the N-terminal/central fragment of Gag protein used as antigen in serological tests. Amino acid changes are indicated, a nonsense codon is indicated in black.
