In brief, we mixed 50% tissue culture infective doses of Kunjin virus strain MRM61C (100 U/mL) in 2% fetal bovine serum (Invitrogen, Carlsbad, CA, USA) with 2-fold dilutions of heat-inactivated patient serum (1:10-1:640) in equal volumes and incubated the mixture for 1 h at 37[degrees]C in 5% CO2.
West Nile Virus neurologic disease in humans, South Africa, September 2008-May 2009
A new lineage, lineage 5, has been proposed for Indian isolates previously comprising lineage 1c, and a reclassification as lineage 6 has been proposed for the Sarawak Kunjin virus strain, which is markedly different from the other Kunjin viruses.
Genetic characterization of West Nile virus lineage 2, Greece, 2010
Lineage 1 strains included the highly pathogenic and neuroinvasive NY385-99 strain (2), the attenuated non-neuroinvasive strain TM 171-03 isolated in Mexico in 2003 (19), hamster-passaged attenuated clones of NY-385-99 (clone TYP-9376 and clone 9317B) (18), and a non-neuroinvasive Kunjin virus strain MRM61C (Table 1).
