GRANULAR VENEREAL DISEASE AND ABORTION IN CATTLE. 



9 



Such is a brief outline of the course of the malady as observed in a 

 majority of cases, but the course is vacillating and erratic in individu- 

 als and in herds. Copulation always intensifies the symptoms, and 

 one can generally identify by clinical examination nearly all cows re- 

 cently bred. 



The use of antiseptics in the vulvo-vaginal tract alters the clinical 

 appearances profoundly. Daily washing of the vagina with non- 

 irritant warm antiseptic solutions causes the symptoms of the malady 

 to decrease rapidly in intensity, and in a few weeks the nodules may 

 almost wholly disappear, the mucosa becomes smoother and softer, 

 the color changes to a pale rose-red, and it looks as if the continuance 

 of the handling would soon eliminate the disease, but in the end some 

 nodules remain, and with a cessation of handling unaccompanied by 

 copulation the symptoms remain static. On the other hand, when pow- 

 erful antiseptics are introduced into the vagina the mucosa becomes 

 irritated, swollen, and edematous, and the nodules become veiled. 



Thus the clinical signs of the malady appear insidiously, usually 

 when the heifer is but a few weeks old; the disease then pursues a 

 comparatively uneventful course up to breeding age, then becomes 

 suddenly intensified, and quickly reaches its zenith, where it main- 

 tains, with certain vacillations, an approximately horizontal course 

 for three or four years, when it begins to abate slowly in intensity, to 

 more or less completely disappear clinically with the advent of old age.
