152 POULTRY DISEASES 



Jaundice is very rare, and appears to result from a long- 

 continued mild congestion of the liver. 



Cercomoniasis (spotted liver) is a type of disease of the 

 liver due to infection {Monocercomonas gallinarum) that may 

 be associated with severe diarrheas. 



Aspergillosis is a disease due to a fungus (Aspergillus 

 fumigatus, and sometimes other species). It commonly af- 

 fects the lungs (pneumomycosis, which see), but may, and 

 occasionally does, affect the liver. 



Amyloid degeneration of the liver, spleen and kidneys has 

 been noted in birds afflicted with tuberculosis. In some cases 

 the liver appears granular and brittle. Amyloid deposits in 

 these organs have also been observed in this laboratory in 

 hens dying of purulent peritonitis.
