Diseases of the Liver 101 



This fact usually distinguishes this disease from tuber- 

 culosis where there are prominent rounded cheesy nodules. 

 In pigeons, however, this cercomonad is said to cause rounded 

 prominent nodules about the size of a pea. 



This same organism (Monocercomonas gallinarum) is also 

 said to be responsible for other diseases. The most impor- 

 tant of these is one form of roup. Canker in squabs and 

 intestinal diarrhea in poultry are other diseases attributed 

 to this parasite. 



This disease can be held in check, it is said, by keeping 

 the poultry plant well cleaned and disinfected and by giving 

 the birds an occasional purgative, e.g., Epsom salts. 



In asj^ergillosis, the liver often presents the appearance of 

 being "studded all over with minute, whitish or yellowish 

 spots." This disease is discussed in Chapter XI. 



Gout 



In cases of visceral gout the liver and adjoining organs are 

 covered with a fine chalky sediment. This substance con- 

 sists of crystals of urate of soda. (See Chapter XIV for 

 detailed description.) 



Sarcomatosis and Carcinomatosis 



In some cases the liver is affected with tumors or cancers. 

 These are usually found in connection with similar develop- 

 ments on the ovaries (see Chapter XX).
