Infection of human fetal dorsal root neurons with wild type varicella virus and the Oka strain varicella vaccine.
The relative ability of a varicella-zoster virus (VZV) clinical isolate and a live attenuated VZV vaccine strain (Oka) to infect human neurons was determined in vitro. VZV infection of neurons prepared in culture from dorsal root ganglia of fetuses was assessed using an infectious center assay. Cultures were infected with 50-5,000 pfu of either VZV and assayed at either 24 or 48 hours post-VZV infection. Cultures infected with the clinical VZV isolate had seven-fold more infected neurons than cultures infected with the vaccine strain VZV.
