APPENDIX. I. 



THE GRANULAR VENEREAL DISEASE OF COWS. 



Infectious Granular Vaginitis. Vaginitis Verrucosa. 

 Infectious Vaginal Catarrh. 



On page 97, we have given a brief account of the granular 

 venereal disease of cattle, basing our description upon European 

 veterinar}' literature. We were not aware, at that time, of the 

 existence of the disease in America. We there suggested that 

 the disease might well be imported at any time, and that it might 

 even then exist in America without its presence having been rec- 

 ognized or announced. 



A few weeks later a communication reached us which led us 

 to suspect the existence of the disea.se in a dairy herd in north- 

 eastern New York. 



A visit of inspection to the herd confirmed our suspicions. It 

 was then attempted to procure data regarding the probable dis- 

 semination of the malady. The herd in which we recognized 

 the malady was one in which no effort was made to raise dairy 

 cows. Fresh cows were bought, milked and bred, their calves 

 used for veal, and the cows butchered or sold whenever unprofit- 

 able for dairy purpo.ses. As a consequence, new cows were fre- 

 quently entering the herd. Some of the new cows, which had 

 been in the stable but a few days, were badly affected, which in- 

 dicated that they had been disea.sed when purchased, and conse- 

 quently that neighboring herds were similarly diseased. Soon 

 afterward several herds in the immediate vicinity were inspected 

 by other veterinarians, and reported similiarly affected. 



The results of these inspections led us to suspect that the 

 malady had a somewhat extensive distribution. One large herd 

 in southeastern New York had been reported to us as suffering 

 persistently from abortion, and we were led to suspect that the 

 granular venereal disease was present, and inspection confirmed 

 our belief. We soon had opportunity to observe the affection 

 in western New York, and e.specially in our immediate vicinity. 

 In the region of Ithaca we have inspected a number of dairy herds, 

 finding them uniformly infected. We do not know of a sound 

 herd in our region.
