CHAPTER X 



DISEASES WHOSE CAUSE HAS NOT BEEN DEFINITELY 

 DETERMINED 



DOG DISTEMPER 



Sabrazes and Muratet examined the blood of four cases of dog 

 distemper at Bordeaux where the nervous form of the disease is 

 frequently observed and is very severe, the mortality exceeding 

 60%. The counts of red and white corpuscles and the amount of 

 hemoglobin were not reported. In one case there were signs of 

 anemia with normoblastic reaction. In another case there were 

 slight anisocytosis and polychromatophilia. The changes in the 

 leucocytes were more pronounced. Polynucleosis with lessened 

 number of eosins was the rule. The absolute number of leucocytes 

 was increased in three cases. The iodine reaction was present each 

 time it was made (three cases). The following table gives the 

 differential counts in the four cases examined.

RINDERPEST 



Though the specific cause of rinderpest has not been determined, 

 the blood of animals sick of the disease is virulent. Jobling states 

 thai it has been proven experimentally thai 0.1 cc. of blood from 

 ■i sick animal injected subcutaneously will produce the disease.
