title: Persistence, latency and reactivation of Japanese encephalitis virus infection in mice.
abstract: Persistent and latent Japanese encephalitis virus (JEV) infection was studied in pregnant and non-pregnant mice. Following intraperitoneal inoculation into pregnant mice JEV persisted for 16 weeks in contrast to 4 weeks in non-pregnant mice. This was followed by a higher frequency of latent infection in pregnant mice. The virus could be reactivated during pregnancy or by cyclophosphamide treatment, the latter being more effective.
