under these deposits llie lissues are sometimes ulcerated and 

 they may completely obstruct the bronchial lumen. In the 



pulmonary tissue 

 catarrhal foci are 

 sometimes found; 

 sometimes disinte- 

 grated tissue com- 

 posed of purulent 

 caseous or more 

 grumous nodules 

 and surrounded by 

 a connective tissue 

 capsule or by an in- 

 filtrated, occasion- 

 ally hemorrhagic, 

 focus, which is at 

 other times i m - 

 l)edded in a hepa- 

 tized tissue (Mar- 

 tin). On micro- 

 scopic examination 

 the deposits and 

 the foci show the 

 moulds. This dif- 

 ferentiates definitely mycotic foci from caseous tuberculous foci 

 or glanders nodules, to which they may be veiy similar. Hepa- 

 tization of neighboring nodules and of the interstitial connective 

 tissue may in cattle simulate the picture of pulmonary tuber- 

 culosis (Rockl). In horses the changes may be similar to pul- 

 monary gangrene (Pech). 



Symptoms. In its spnptoms and course the disease is 

 frequently similar to catarrhal pneumonia, and the clinical 

 picture is therefore initiated by the symptoms of a bronchial 

 catarrh. 



In birds the respiration becomes rattling, gasping and more 

 and more difficult. The appetite is poor, but the thirst is much 

 increased. The animals do not like to move; their wings droop 

 and they sit long in one place with ruffled feathers and som- 

 nolent. The buccal mucosa sometimes shows yellowish or 

 greenish deposits (Potain). The emaciation progresses more 

 and more; diarrhea comes on and the completely exhausted 

 animals die after a period of four to eight weeks' duration. 



S\miptoms pointing to a chronic pulmonary disease are 

 observed in mammals and may exist for weeks and months; 

 the animal suffers from increasing respiratory difficulties, they 

 become emaciated to skeletons and completely exhausted. More 

 rarely the disease takes a rapid course and then leads to more 

 acute symptoms, eventually with a hemorrhagic discharge from 

 the nose and to hematuria (Thary & Lucet).
