MALIGNANT CATARRH OF SHEBP. 



This resembles the corresponding disease of cattle, but cannot 

 as yet be considered identical with it. Its occurrence in epizootic 

 form strongly bespeaks an infection or the taking of toxic mat- 

 ters produced by microorganism outside the body. There is in- 

 tense congestion with redness, often ramifying, of the nasal 

 mucosa, conjunctiva, and other connecting mucosae. The general 

 color of the affected mucosa may be bright scarlet, dark red or 

 dark blue with numerous petechial points implying the action of 

 a deadly haemolytic poison on the blood. The mucosa is covered 

 with a slimy, creamy or caseous product, and is strongly in- 

 filtrated, tense and it may be glistening. Coincident inflammation 

 of other mucosas, especially that of the bronchia, and also of 

 the parenchyma of the lungs and of the skin bespeaks a general 

 diffusion of the poison throughout the system as in the cattle 

 affection; Prevention and treatment may be attempted along the 

 same general lines as in the ox. 



CONTAGIOUS DISEASES OF THE NOSE. 



These are omitted here to be treated under that heading.
