Chronic Rabies Virus Infection of Cell Cultures

Chronic rabies virus infection of cell cultures.

Exposure of both mammalian and reptilian cells in tissue culture to different strains of fixed rabies virus resulted in a carrier type of infection. No cytopathic effect was observed in either type of culture; infected cultures could be maintained by cell transfer for unlimited numbers of passages. A consistent pattern of cyclically rising and falling levels of viral infection was observed by f...

Propagation of goat pox virus on monolayer cell cultures

B cell infection and activation by rabies virus-based vaccines.

Replication-deficient rabies viruses (RABV) are promising rabies postexposure vaccines due to their prompt and potent stimulation of protective virus neutralizing antibody titers, which are produced in mice by both T-dependent and T-independent mechanisms. To promote such early and robust B cell stimulation, we hypothesized that live RABV-based vaccines directly infect B cells, thereby activati...

Rabies virus infection of primary neuronal cultures and adult mice: failure to demonstrate evidence of excitotoxicity.

Cultures derived from the cerebral cortices and hippocampi of 17-day-old mouse fetuses infected with the CVS strain of rabies virus showed loss of trypan blue exclusion, morphological apoptotic features, and activated caspase 3 expression, indicating apoptosis. The NMDA (N-methyl-D-aspartate acid) antagonists ketamine (125 microM) and MK-801 (60 microM) were found to have no significant neuropr...
