cattle: commissioners' report. 253 



for general use. During this time twenty more pigs died at 

 Terry's farm and two other herds became infected in the neigh- 

 borhood. After consulting with your board, you authorized 

 me to use the serum treatment and make the necessary investi- 

 gation and stamp out the outbreak if possible. I sent for a 

 supply of Dr. Vaux's cholera anti-toxin and at the same time 

 I investigated cases which were reported to me. Charles Fuller, 

 North Fairfield, lost one pig bought at Terry's farm, in Decem- 

 ber, 1905 ; A. B. Jenkins of Fairfield Centre lost four, also 

 bought at Terry's farm in December, 1905. Silas Small lost 

 4, Wm. Hersom lost 3, Fred Pullen lost 2, Maurice McNally 

 lost 7, and Oscar Carroll 12; no connection with Terry's farm 

 could be detected. January 26th, 1906, I began the serum treat- 

 ment, which requires four injections, one injection on ist, 2nd, 

 5th and 2 1 St day. Thirteen head were treated at Terry's farm; 

 all recovered. It might be suggested that the remaining 13 

 were immune, to which suggestion I will answer that 7 head 

 of those 13 showed temperature over 104, which proved that 

 the disease existed at that time, and furthermore the same day 

 before the inoculation one dead pig was found. 



At Oscar Carroll's, who lost 12 head, 9 were bought and 

 placed in the same infected stable. They were inoculated, 

 and all escaped the disease. Fifteen head were treated at 

 P. Rheaume's, where six of them appeared very sick, but only 

 one died. 



No other cases have been reported, and I believe the outbreak 

 to be stamped out, and I believe the serum treatment to be a 

 rational one and practical. 



In reading the report of the Bureau of Animal Industry one 

 can see that many outbreaks of supposed hog cholera had been 

 successfully treated with cholera anti-toxin; but the Bureau 

 claimed that the diagnosis of the disease was doubtful and it 

 was not advisable to give too much credit to the serum treat- 

 ment. 



There can be no question in the diagnosis of this present out- 

 break, as the bacteriological findings have proved to be true. 



Respectfully submitted, 



A. JOLY, D. V. S."
