ACUTE BULBAR PARALYSIS 75 



edema or congestion; severe dyspnea accompanied by 

 rustling sounds. The tongue protrudes from the 

 mouth; diarrhea is present. The temperature now 

 keeps going down until it may be several degrees 

 subnormal; the periods of coma are prolonged, and 

 the cow dies on the fifth or sixth day after the begin- 

 ning of the attack. 



Some cases run a somewhat slower course, dying on 

 the eighth to tenth day. Now and then a case sur- 

 vives the acute attack, gradually assuming a subacute 

 form and lingering along for several weeks. In the 

 latter form inspiration pneumonia develops at last and 

 pulmonary gangrene supervenes. 



The treatment of this disease is far from satisfac- 

 tory. In fact, all that we can do is to treat the symp- 

 toms as they arise. Until the exact nature of the con- 

 dition is discovered the treatment will be empirical. 



We can point to no particular remedial agent or 

 method of treatment which has given good results in 

 our practice. We have used every form of treatment 

 which the symptoms, and pathology so far as it is 

 understood, would indicate as helpful, but without 

 success. For this reason we refrain from suggesting 

 any method of handling this disease, leaving the 

 treatment to the judgment of the individual veteri- 

 narian. 



Because of the apparent semi-infectious nature that 

 the disease sometimes assumes, when it occurs in the 

 enzootic form, we Avould suggest as a precautionary 

 matter the thorough disinfection of the premises on 

 which a case develops. If it can conveniently be ar- 

 ranged the patient should be taken out of the herd 

 and isolated. It is impossible to differentiate the spo- 

 radic from the enzootic form clinically; because of 

 this all cases of this disease should be regarded as 

 being communicable.
