RABIES 611 



rabies. But this condition comes on suddenly and lasts 

 only a few minutes to disappear completely until the next 

 attack, (h) Eclampsia is differentiated by its occurrence 

 in bitches at or near the time of whelping, clonic spasms 

 which affect the entire body and none of the other char- 

 acteristic symptoms of rabies, (i) Infectious bulbar paral- 

 ysis in which the symptoms are quite similar to rabies. 

 It is distinguished from rabies by the absence of the furious 

 attacks, viciousness and paralysis of the lower jaw. The 

 blood and brain tissue are infectious and the saliva not. 

 This disease develops suddenly and runs a more rapid 

 course than rabies. Finally, there are a few conditions in 

 which the animal will show more or less nervousness, but 

 none of the other symptoms of rabies. Animal inoculation 

 and the microscopic examination of the brain should be 

 made in all cases of doubt. 



Treatment. After rabies has once developed in an animal 

 no treatment will have any effect on the disease. Bitten 

 wounds that have been caused by a rabid animal should 

 be treated promptly. They should be opened freely, and 

 if hemorrhage takes place it is all the better, as it will tend 

 to remove the virus from the wound. The wound should 

 be washed freely and thoroughly with potassium perman- 

 ganate solution (1 per cent.), or bichlorid solution (1 to 

 1000). Cauterization of the wound with silver nitrate is 

 also recommended. The success of this treatment in pre- 

 venting the development of the disease will depend upon 

 the length of time which has elapsed after the bite, and the 

 thoroughness in which the antiseptic or caustic is applied. 

 Disinfection of the wound alone should not be depended 

 upon for the prevention of rabies. 



Preventive Inoculation. Preventive inoculation is being 

 used with great success in animals, and is highly recommended 

 in all cases where there is any doubt about the animal 

 being infected. 



INFECTIOUS BULBAR PARALYSIS. 



Pseudorabies. 



Definition. An infectious disease affecting dogs, cats, rats, 

 horses and cattle resembling rabies in many respects.
