The examination of 57 samples pairs (cornea and saliva ) collected from 18 bovines with experimental rabies by both techniques direct fluorescent antibodies applied to cornea impressions and intracerebral mice inoculation with saliva revealed that the former provided a greater frequency of positive reactions (84,2% ) than the latte r (22,8%). In addition, it was observed that once the cornea test had provided a positive result such condition was maintained until death of the animal, and in no occasion could the virus be detected in saliva without a positive result with the cornea test on the same animal. The false negative values obtained with the cornea test (16,7% ) suggested that a negative result does not exclude the possibility of the disease.
