334 Diseases of the Genital Organs 



affected. In such cases, as shown in Figures 98 and 99, the 

 chief clinical phenomenon is inability to protrude the penis 

 and copulate. The inflamed glands induce adhesions which 

 inhibit the elimination of the sigmoid flexure. Palpation 

 of the region readily enables the veterinarian to detect the 

 enlarged glands. 



The enlargement of the lymph glands of the sheath, pre- 

 puce, or sigmoid flexure constitutes strong evidence of pri- 

 mary venereal tuberculosis. Other infections may induce 

 similar adenitis, but commonly the veterinarian is justified 

 in provisionally diagnosing such lesions as tuberculosis. He 

 may, should circumstances demand, search for bacterial or 

 other evidence. On the whole, any chronic adenitis of these 

 glands ruins the breeding value of the bull and dictates 

 slaughter. A positive diagnosis is highly important, even 

 when made post mortem. If it is tuberculosis — and that is 

 the rule — ^there must be highly dangerous cows in the herd, 

 the genitalia of which should be subjected to very rigid 

 search for tuberculosis. While a bull may become infected 

 in copulating with a cow when the exterior of the vulva is 

 contaminated with tubercle-bearing fecal excreta, this is 

 improbable. The assumption should generally be that the 

 infection has arisen from copulating with a female having 

 tuberculous genital catarrh. Such an offender should be 

 detected and eliminated. She is almost always incurably 

 sterile. She constitutes a great peril to any breeding sire, 

 and is one of the worst "spreaders" of tuberculous infection. 



Tuberculosis of the Female Genitalia 



Every part of the genital organs of the cow is subject to 

 invasion. My collection contains examples of ovarian, tubal, 

 uterine, cervical, and vaginal tuberculosis, and I have ob- 

 served clinically vulvar tuberculosis. 



(1) Ovarian tuberculosis is very rare, but is far more 

 common than orchitic tuberculosis. The ovary is more ex- 

 posed to the infection than the testicle, especially in the 

 presence of extensive peritoneal lesions. I have obtained 

 but two good examples. One of these. Fig. 100, is highly
