CEKEBKO-SPINAL MENINGITIS 117 



attack does not confer immunity ; in this way it 

 resembles nearly all cocci infections. 



Treatment. — x\s many authors contend that the 

 causative organisms in this disease are the same or 

 very closely related to the Diplococcus intracellular is 

 meningitidis^ which causes the same disease in man, 

 the use of the serum prepared for treatment of this 

 disease in humans is indicated. In man the best 

 results have been obtained from the use of a poly- 

 valent immune serum, injected intrathecally (for 

 description of this procedure see Tetanus). Serum 

 used in the human subject in this manner reduced 

 the mortality by half. Personally, I have treated one 

 case of cerebro-spinal meningitis with human anti- 

 meningococci immune serum. The subject was a 

 month-old Aberdeen Angus pedigree calf. The in- 

 jections were made by lumbar puncture. Three injec- 

 tions of 30 c.c. serum at intervals of forty-eight hours 

 were given, recovery following. The only trace of the 

 disease which remained was a slight difficulty in 

 regaining the standing position when the animal lay 

 down ; he would get on to his knees and remain in this 

 position for a minute or so before finally getting on 

 his feet. 



In valuable animals suffering from this disease 

 serum treatment should be employed, the serum 

 prepared for human meningitis being easily obtain- 

 able. If this cannot be procured, ordinary normal 

 serum should be used, preferably obtained from an 

 animal of the same species as the one on which it is
