Isolation and phylogenetic grouping of equine encephalosis virus in Israel

During 2008–2009 in Israel, equine encephalosis virus (EEV) caused febrile outbreaks in horses. Phylogenetic analysis of segment 10 of the virus strains showed that they form a new cluster; analysis of segment 2 showed ?92% sequence identity to EEV-3, the reference isolate. Thus, the source of this emerging EEV remains uncertain.
