A Kunjin virus
isolate from 2003 (AY274505) and isolate EthAn4766 from Ethiopia (AY603654) also had that mutation.
Transmission of WNV in southern Africa and of Kunjin virus
in Australia increases in the early months of the year after heavy spring and summer rainfall (2,11).
Vaccination of crows with Kunjin virus
, a subtype of WNV, protected against WNV, and a DNA vector, which elicited expression of attenuated Kunjin virus
, provided protective immunity against WNV in mice (46).
Isolates from Russia, Romania, France, and Italy formed a distinct cluster, as did 3 Kunjin virus
isolates and their close relatives from China and Egypt (Figure).
