WNV is serologically related to the Japanese encephalitis complex of flaviviruses (Flaviviridae), which includes Saint Louis encephalitis virus (SLEV) (in North and South America), Japanese encephalitis virus (Asia), and Murray Valley encephalitis virus (Australia) (2).
Serum samples were screened for flavivirus-neutralizing antibodies by plaque-reduction neutralization test (PRNT) according to standard methods (11) and by using challenge inocula of 100 plaque-forming units (PFU) WNV strain NY99-4132 and Saint Louis encephalitis virus (SLEV) strain TBH-28.
West Nile virus (WNV; family Flaviviridae, genus Flavivirus) is a member of the Japanese encephalitis virus complex, which also includes Japanese encephalitis virus, Saint Louis encephalitis virus (SLEV), and Murray Valley encephalitis virus (1).
HI assays were performed by using Saint Louis encephalitis virus (SLEV) antigen as previously described (9).
