Replication of HFRS Virus in Cultured Human Lymphoblastoid Cells with B Cell Characteristics
Abstract: The susceptibility of human B lymphoblastoid cells to HFRS virus infectionwas studied. The results showed that the cells were productively infected byHFRS virus. The persistently infected cells had no obvious cytopathic effects andwere indistinguishable morphologically from uninfected cells. It was difficult toidentify complete virions in infected lymphoblasts by electron microscopy con-trasted with strong immunofluorescence staining for intracellular HFRS virusantigens observed in the majority of these cel...
