Demonstration of Nuclear Immunofluorescence in Rift Valley Fever Infected Cells

Abstract
Eosinophilic intranuclear filaments in Rift Valley fever virus infected [calf testis, baby hamster kidney BHK 21 Cl 13 and African green monkey kidney Vero] cells, fluoresce specifically in an indirect technique with [sheep] antiserum to the virus. Actinomycin D failed to suppress development of the filaments or replication of the virus.
