Figure 1From: Reduced viral burden in paralytic compared to furious canine rabies is associated with prominent inflammation at the brainstem levelQuantitative analysis of rabies viral antigen. Following immunostaining for rabies antigen (A), all neurons in each captured image are manually outlined (B) and analyzed by computer software. The three antigen parameters assessed are: (1) percentage of positive neurons, (2) average antigen area in positive neuron, and (3) average antigen area per neuron.
