BACTERIA PATHOGENIC FOR ANIMALS, NOT FOR MAN 2OI 



are similar to the typhoid bacillus in gelatin. They form 

 small embolic processes in the capillaries. They cause only 

 a local disturbance in rabbits when subcutaneously injected. 

 An acid fermentation is produced in milk.

The bacteria of this third division are very motile. The 

 hog-cholera bacilli lie in the spleen and other organs in small 

 masses like the typhoid bacillus.

Rabbits die in four to eight days without any local disturb- 

 ance. The growth on potato is strong. 



The Swedish swine-plague bacillus occupies a position 

 between that of hog-cholera and Bacillus coli communis. 



The various swine-plague bacilli are but little active in fowls, 

 differing thus widely from the chicken-cholera bacillus.
