XI. B, 6 Boynton: Rinderpest in Swine 231 



October 14, 1915, pig 214 developed an afternoon temperature 

 of 40.5° C. This was nine days after pig 216 was placed in 

 corral No. 2 and eight days after its death, and five days after 

 the initial rise in temperature of pig 218, which was also kept 

 in corral No. 2. 



October 16-18, N. E. 



October 18, died of rinderpest, showing typical lesions of that 

 disease upon autopsy. 



In summing up the results of experiment 14, it will be noted 

 that pig 214 did not contract rinderpest in corral No. 1 which had 

 contained a pig that died of rinderpest ten days previous to the 

 admission of pig 214 to the corral. It will also be noted that pig 

 214 did have a temperature and showed mild symptoms of hog 

 cholera, which it possibly contracted in corral No. 1. It will be 

 noted also that pig 214 did finally contract rinderpest and 

 died of that disease and that the disease was undoubtedly 

 brought to it by means of the caretaker. 



Also it will be noted that a pig can suffer from an apparently 

 mild attack of hog cholera and recover from that disease and 

 later contract rinderpest and die. 



PIGS INOCULATED WITH VIRULENT BLOOD FROM PIGS SICK WITH 



RINDERPEST 



The following experiments were designed to furnish infor- 

 mation regarding the possibility of pigs contracting rinderpest by 

 inoculating them with blood taken from pigs sick with rinderpest. 

 The animals that were inoculated were kept in screened stalls 

 in a shed, which was free from disease, until they developed a rise 

 in temperature, at which time they were removed. 



EXPERIMENT 15 



Pig 206. — Known history prior to the experiment: This ani- 

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

 May 28, 1915, and placed in quarantine. 



May 29, 1915, pig 206 was inoculated with 10 cubic centimeters 

 of virulent blood from pig 185. 



History of pig 185 at the time the virulent blood was drawn from it: 

 May 29: Fourth day of temperature, N. E. The a. m. tempera- 

 ture was 39.4° C; p. m. temperature, 40.1° C. For complete 

 history see experiment 1. 



June 2, pig 206 developed a rise in temperature, registering, 

 in the afternoon, 40.2° C. ; this was four days after inoculation. 



June 3, this animal died. Autopsy did not reveal any marked 

 lesions.
