SECTION III. THE GENITAL INFECTIONS OF SWINE 



CHAPTER XVIII 



SPECIFIC GENITAL INFECTIONS 



The Nodular Venereal Disease 

 Outbreaks of specific venereal diseases in swine have been 

 recorded at intervals, but the records have been indefinite. 

 When describing the nodular venereal disease of cattle, it 

 was stated that the infection is common in cattle, swine, 

 sheep, and presumably in goats. It has been stated by some 

 writers that in certain herds the infection caused destruc- 

 tive outbreaks of abortion and sterility in sows. The facts 

 appear to be that notable losses occurring in certain herds 

 of swine caused the veterinarian to search for, and quite 

 naturally to find, the lesions, and upon this evidence the con- 

 clusion was reached that the infection causing the lesions 

 was responsible for the abortion. The assumption may be 

 true or untrue. What has been said of the infection in cattle 

 is presumably equally true in swine, and it does not re- 

 quire repetition. 



CHAPTER XIX 

 NON-VENEREAL SPECIFIC INFECTIONS INVADING 

 THE GENITALIA OF SWINE 

 Genital Tuberculosis 

 Genital tuberculosis has been reported but rarely in swine 

 and probably does not play a very important economic part 

 in swine husbandry. I have in my collection but one speci- 

 men of genital tuberculosis of swine — tuberculosis of the 

 testicle, illustrated in Fig. 215. The gland is from a pure- 

 bred boar belonging to a herd devoted to growing purebred 

 swine for breeding purposes. They had a liberal supply of 

 raw milk from a herd of purebred dairy cattle in which tu- 

 berculosis was rampant. The symptoms of genital tubercu- 

 losis in swine are presumably the same as in cattle. The 

 tuberculosis of swine is ordinarily of bovine origin. Tuber- 

 cular invasion of the genitalia of swine is to be avoided by 

 the genera] measures for preventing swine tuberculosis. 

 When present, genital tuberculosis has the same dangers for 

 other swine that bovine genital tuberculosis has for other 

 cattle. There is no remedy for the affected animal.
