FUNGOID DISEASES OF ANIMALS. 



Here again only those diseases caused by the 

 true fungi will be described ; the reader being re- 

 ferred to books on animal pathology for descrip- 

 tions of the innumerable diseases caused by bacteria. 



I. Wooden Tongue [Actinomyces bovis). — Also 

 known as actinomycosis, lumpy jaw, cancer of the 

 tongue, etc. It appears most frequently in the 

 ox, but pigs and human beings are sometimes at- 

 tacked. In the ox the tongue is the chief seat of 

 disease, but in castrated animals the spermatic 

 cord may become infected ; it has also been found 

 in the peritoneum. 



Symptoms. — On and within the tongue small 

 flattened, greyish -yellow or reddish nodules or ab- 

 scesses appear \ to i inch in diameter, microscopic 

 examination revealing the presence of a fungus. 

 These nodules harden and sometimes lime is de- 

 posited, giving a granular appearance. The animal, 

 rolls its tongue about, and swallows with difficulty ; 

 saliva drops from the mouth, and the tongue is 

 swollen and hardened. The disease may spread 

 from the tongue to the lower jaw.
