摘要
Rabbit hemorrhagic disease virus (RHDV) causes devastating effects on European rabbit (Oryctolagus cuniculus) populations in the Iberian Peninsula. According to the information available, only genogroup 1 strains were circulating in Iberian wild rabbits until 2011; the antigenic variant G6 has been sporadically detected in rabbitries since 2007. Here, we show for the first time that G3-G5 strains were already present in mainland Portugal in 1998 and that G6 has been circulating since at least 1999. Moreover, we report a G3-G5 strain from the Azores collected in 1998, which is the likely ancestor of Azorean G3-G5like strains. These observations improve the current knowledge on RHDV epidemiology in the Iberian Peninsula and the Azores.
