To the Editor: West Nile virus (WNV) is a member of the genus Flavivirus within the Japanese encephalitis antigenic complex.
Serosurvey of West Nile virus and other flaviviruses of the Japanese encephalitis antigenic complex in birds from Andalusia, southern Spain.
The natural cycle of all members of the JE antigenic complex
of Flaviviruses involves birds as the main amplifying host and several species of mosquitoes as the vectors, ornithophilic mosquitoes, particularly, Culex species.
Similarly, ONN virus lineage has been considered a distinct group of viruses within the antigenic complex
West Nile virus is a member of the Japanese encephalitis antigenic complex
Genus: Flavivirus Japanese Encephalitis Antigenic Complex
The HI and EIA tests used in this study cross-react only poorly between alphaviruses in different antigenic complexes
but may cross-react with other alphaviruses within the same antigenic complex
However, antibodies produced during ILHV infection cross-react in serologic assays to other flavivirus antigens, and ILHV was originally classified in the Japanese encephalitis antigenic complex
SFV antibodies failed to detect ONNV by IFA, although both viruses are members of the same antigenic complex
That we found antiborrelial-complex antibodies may suggest the presence of a new species in this antigenic complex
containing cross-reactive antigens, but many other studies are necessary to confirm it.
To investigate the genetic relationship of the Austrian USUV with other flaviviruses in the JEV antigenic complex
, we constructed a phylogenetic tree by using the programs in the PHYLIP package; we also included in the phylogenetic analysis three other important mosquito-borne flaviviruses (YFV, SLEV, and DENV3).
West Nile (WN) virus is a member of the Japanese encephalitis (JE) antigenic complex
of the genus Flavivirus, family Flaviviridae.
