VETEKINAKY MEDICINE. 



[Report of the] department of veterinary science, J. B. Paige {Massachu- 

 setts Sta. Rpt. 1916, pp. 89a-92a). — Experiments in the prevention of liog 

 cholera were conducted in a herd of from 75 to 150 hogs that were fed upon 

 garbage from a source which on two previous occasions had caused outbreaks 

 of hog cliolera. A part of the herd in which an artificial immunity had not 

 been established by means of serum and virus was treated by the simultaneous 

 method, the Globulin preparation of serum being used, and another lot was 

 treated with a refined Amber Serum. The Globulin preparation showed an 

 advantage over the usual antihog-cholera serum and the refined Amber Serum 

 gave very satisfactory results. 



The status of the work with Bacterium pullorum relating to the specificity 

 of its antibodies, with special reference to the agglutinins ; to toxins elaborated 

 and their relation to specific conditions in adult birds ; and to the production 

 of antibodies, with special reference to potency and rate of production, is briefly 

 reported upon. The investigations have shown that the toxin is endotoxic and 

 that it is most intimately connected with the bacterial cell. 



The suppression and eradication work with bacillary white diarrhea in fowls 

 shows the agglutination test to be most accurate and reliable. The disease 

 has been completely stamped out in the flocks that have been tested during 

 the past two years and in which the directions for the handling of the flocks 

 have been carried out. Of the 14,851 birds tested, owned by 78 different parties 

 in 57 different towns scattered throughout the State, only 2,207 gave positive 

 reaction.
