SPECIFIC INFECTIONS OF COITION 

 Venereal Diseases. 



Venereal diseases have been described in nearly, if not all of 

 our domesticated animals, especially in horses, cattle, sheep and 

 dogs, with briefer references in our literature to such diseases in 

 goats, swine and rabbits. In horses we recognize two well defined 

 venereal affections, Dourine or Maladie dti Co'it and the Eruptive 

 Venereal Disease or Geiiital Horse Pox ; in cattle the Vesicular 

 Venereal Disease 2lX\^ the Infectious Grajiular Venereal Disease ; 

 in the dog the Venereal Gra?nilomata ; and in sheep an Ulcerative 

 Venereal affection.

Dourine of the horse is the most serious venereal disease known 

 among domestic animals, both on account of its wide geograpical 

 distribution and the mortality and loss caused by it. It is widelj' 

 dissemminated in Europe, Asia, Africa and North America. It 

 has been recognized for more that a century and has appeared in 

 all the leading countries on the European continent. In English 

 speaking countries, it was first recognized by the author at Wa- 

 pella in DeWitt County, Illinois, in the spring of 1886 among 

 imported French draft stallions and the mares which had been 

 served by them. The disease in Illinois apparently broke out 

 in 1884 or 1885, but its nature was not determined until 1886 and 

 even then its seriousness was not fully appreciated so that it was 

 not until 1887 that vigorous measures were undertaken for its 

 control and eradication. In the meantime, numerous animals had 

 been sold from the infected area and widely disseminated over 

 the country in a manner which made it impracticable to effect- 

 ively trace them to their ultimate destination. When the im- 

 portance of the malady became recognized it was promptly placed 

 under control and was so completely eradicated that up to the
