(PROFESSIONAL PAPER.) THE GRANULAR VENEREAL DISEASE AND ABORTION IN CATTLE. By W. L. Williams,1 Professor of Surgery, Veterinary Department, Cornell University. INTRODUCTION. Early in 1909 the writer had publicly announced the existence in a dairy herd in New York of the granular venereal disease, nodular vaginitis, or vaginitis folliculorum chronica contagiosa. Later ob- servations showed that it was general, if not universal, among the herds of the State. This disease having been held responsible by many continental European veterinarians of high authority for the abortion and sterility of cows, it was deemed important that first of all it should be determined how widely and extensively this malady exists among the cattle of the United States. In order to accom- plish this, it was decided to make post-mortem observations upon the genitalia of cows, heifers, and heifer calves on the killing floors of abattoirs at some of the principal slaughtering centers. The inspec- tors in charge of the Federal meat inspection at these stations, under instructions from the Chief of the Bureau of Animal Industry, United States Department of Agriculture, cooperated most heartily, and a large volume of most interesting material was furnished in the most convenient manner possible for inspection. The importance of abortion and sterility in cows is rapidly becom- ing more acutely felt by breeders, and is each year playing a more serious part in the national economy. By interfering more and more with the reproductive powers of cows, these diseases exert an unfavor- able influence upon the production of meat, milk, and dairy products, decreasing the supply and increasing the cost. i In conjunction with the Pathological Division, Bureau of Animal Industry, United States Depart- ment of Agriculture.
