Differential effect of the route of inoculation of rabies virus on NeuN immunoreactivity in the cerebral cortex of mice

Int. j. morphol; 34 (4), 2016
Rabies is a lethal disease caused by a neurotropic virus that produces inconspicuous morphological changes hardly observable with conventional histopathology. The fatal outcome caused by rabies could be attributed to specific biochemical changes that severely impact neuronal function. The neuronal nuclea...
