  • Lineage 2 West Nile virus as cause of fatal neurologic disease in horses, South Africa 
    Venter, Marietjie; Human, Stacey; Zaayman, Dewald; Gerdes, Gertruida Hermanna; Williams, June Heather; Steyl, Johan Christian Abraham; Leman, Patricia A.; Paweska, Janusz Tadeusz; Setzkorn, Hildegard; Rous, Gavin; Murray, Sue; Parker, Rissa; Donnellan, Cynthia Mary Bridget; Swanepoel, Robert (Coordinating Center for Infectious Diseases, Centers for Disease Control and Prevention, 2009-05-06)
    Serologic evidence suggests that West Nile virus (WNV) is widely distributed in horses in Southern Africa. However, because few neurologic cases have been reported, endemic lineage 2 strains were postulated to be non-pathogenic ...
