may slough, and granulating tissue, commonly called "fungoid 

 growths," develop. The invasion of the organism and the 

 extending of the necrosis may continue until the tendons, liga- 

 ments and even the bones may be attacked. There is going

 cells, and granulation tissue (Mohler).

MISCELI^ANEOUS INFECTIONS WITH BACILU 



§ 219. Enzootic in cattle caused by a bacillus of the 

 enteritidis group. In 1902, Mohler and Buckley* described 

 an outbreak caused by B. etiteritidis among cattle in a stable of 

 21 animals of which 8 contracted the disease and died. Three 

 others exhibited the early symptoms. 



The symptoms were first refusal of food, suspension of 

 urination and diminution in lactation. There was excessive

 to 104. 1° F. The visible mucosae were congested. There 

 was a wild expression in the eyes and the animals were very
