SIV (virus de la inmunodeficiencia del simio)
Scope note: Especie del género LENTIVIRUS, del subgénero de VIRUS DE LA INMUNODEFICIENCIA DE PRIMATES, que inducen un síndrome de inmunodeficiencia adquirida en simios (SIDAS). La organización genética del SIV es prácticamente idéntica a la del VIH. La secuencia de nucleótidos del SIV es homóloga en el 50 por ciento a la del VIH-1. El SIV y el VIH-2 muestran propiedades estructurales e inmunológicas muy semejantes, y una homología del 75 por ciento. El SIV no produce inmunodeficiencia en su huésped natural, el mono verde africano, pero causa el SIDAS en el macaco de la India.
