Genotyping Based on the LTR Region of Small Ruminant Lentiviruses from Naturally Infected Sheep and Goats from Mexico

Alignment of genotype B reference sequences and those obtained in this study. Transcription factor binding sites AML (vis), AP-1, and AP-4 are shown in boxes. Minimal changes are observed in the AMLV (vis) and AP-4 sites. A higher number of changes are seen at the AP-1 sites in the sequences. The TATA box is shown in a box; no changes were observed in the sequences. Poly A site is shown in a box showing minimal changes. Limits of the regions U3, R, and U5 are marked.
