Jamadagni, S. B. | Singh, C.K.
The study on prevalence and pathology of rabies in Punjab was undertaken on 196 cases wherein a total of 118 cases were found positive for rabies in different animals species using Seller's staining, FAT, histopathological examination and biological testing. The species-wise prevalence of rabies in Punjab was found to be highest in buffaloes followed by dogs and cattle. Increased incidence of rabies in dogs, buffaloes and cattle occurred in spring and monsoon seasons, which coincided with breeding pattern of dogs. The young and male dogs were found to be more prone to rabies virus exposure. As compared to rabid buffaloes, rabid cattle more commonly revealed hyper salivation and frequent micturition. Bellowing and difficult intake of food were found to be more common in buffaloes than in cattle. Symptoms found in rabid dogs were not reliable for clinical diagnosis of rabies. In case of bovines pathognomonic lesions (Negri bodies) were commonly found in cerebellum. As compared to cerebellum of rabid buffaloes, cerebellum of rabid cattle showed more pathognomonic Negri bodies. Negri bodies were more commonly present in hippocampus of rabid dogs. Neuronal necrosis and reactive inflammatory changes were found more commonly in brainstem of dogs, buffaloes and cattle. Neuronal necrosis and reactive inflammatory changes were found more commonly in rabid dogs than in rabid bovines.
