XI. B, 6 Boynton: Rinderpest in Swine 231 



PIGS INOCULATED WITH VIRULENT BLOOD FROM CATTLE AND PIGS 



SICK WITH RINDERPEST 



The following experiment was designed to furnish informa- 

 tion regarding the possibility of pigs contracting rinderpest 

 when inoculated with a mixture of virulent rinderpest blood 

 from cattle and pigs. 



EXPERIMENT 21 



Pig 244. — Known history prior to the experiment: This ani- 

 mal was a native pig, 6 months old, purchased in Manila and 

 kept in quarantine seventy-eight days before it was used. At 

 no time during this period did it have a high temperature or 

 show any symptoms of sickness. 



January 4, 1916, pig 244 was inoculated with a mixture of 

 25 cubic centimeters of virulent rinderpest blood from bull 3976 

 and pig 237. 



History of bull 3976 from which blood was taken: 



December 28, 1915: Bull 3976 was inoculated with 100 cubic centi- 

 meters of virulent rinderpest blood procured from a sick carabao 

 in Pampanga Province. 



December 31 : First rise in temperature, registering, a. m., 39.1° C. 



January 3, 1916: Bled to death for virulent blood to be used in 

 immunizing work. 



For history of pig 237, from which blood was taken, see experi- 

 ment 9. 



January 7, pig 244 developed a rise in temperature, register- 

 ing, in the morning, 39.8° C. ; in the afternoon, 40.6° C. ; this 

 was three days after the inoculation. 



January 10, this animal's afternoon temperature was 41.3° C, 

 which was the highest temperature registered during the course 

 of the disease. 



January 10-24, D., E. L. 



January 24, died of rinderpest, presenting good lesions of 

 that disease upon autopsy. 



In summing up the results of this experiment it will be noted 

 that a pig will contract rinderpest when inoculated with a mix- 

 ture of virulent rinderpest blood from cattle and pigs. 



PIGS DRENCHED WITH VIRULENT BLOOD FROM CARABAOS SICK WITH 



RINDERPEST 



The following experiment was designed to furnish information 

 regarding the possibility of pigs contracting rinderpest when 

 given virulent rinderpest blood from carabaos by drench.
