Abstract
Equine infectious anaemia virus (EIAV) is classified within the Retroviridae and, like other lentivirus, has the propensity for considerable antigenic variation. An extensive phylogenetic analysis in Bayesian fashion, with significant amounts of new EIAV gag sequence information, revealed a strong geographic compartmentalization clearly related to the phylogeographic history of modern horses, pointing out that New World EIAV strains form a distinct group with a potentially common origin. This evidence suggests that a single founder event may have occurred during the reintroduction of horses to the Amer- icas by European colonists in the 15th century, a possibility that raises many interesting scenarios with implications for all evolutionary and ecological studieI documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
