The Nodular Venereal Disease 301 



Inspection of the mucosa of the glans, prepuce and sheath 

 reveals the presence of a few or many small nodules, as in- 

 dicated in Figs. 85, 86, 87. The number and appearance re- 

 main static in the calf up to breeding age. Coitus greatly 

 increases the number of granules, which tend to become 

 confluent, causing an enormously thickened, roughened con- 

 dition of the mucosa of the parts. Even with this increase

of the infection, there is ordinarily no notable interference 

 with coitus or fertility. Now and then, however, the parts 

 become so intensely inflamed that the bull hesitates to copu- 

 late. The attrition of coitus removes the epithelium from 

 the summits of some of the nodules, creating minute abra- 

 sions and inducing hemorrhage. In still more severe cases, 

 the involved mucosa becomes so swollen that the penis can 

 no longer be protruded, and phimosis becomes established.
