440 CHRONIC INFECTIOUS DISEASES 



becomes mixed with tubercular exudate, is watery and of 

 greenish color,, or contains white flocculee. 



(e) Bowels. — The only tangible clinical symptom of intes- 

 tinal tuberculosis is a persistent and incurable diarrhea. 

 The patient usually soon emaciates, becomes cachectic, and 

 dies. 



(/) Genital Organs. — Peritoneum. — A remarkable develop- 

 ment of peritoneal tuberculosis can be present and the 

 patient not only appear in health but gain in flesh. In cows 

 tuberculosis of the peritoneal covering of the ovaries may 

 induce nymphomania, the animal showing almost continuous 

 estrum. Later the patients fall off in flesh. 



ig) Uterus. — The most constant symptom is a vaginal 

 discharge of a mucopurulent, yellowish, ichoric, fetid char- 

 acter. Rectal examination may reveal the greatly thickened, 

 rigid wall of the body and horns of the uterus. Failure to 

 conceive (perpetual bulling) and abortion may be attending 

 symptoms. In the later stages sexual desire is lost. 



{h) Vagina. — Hickory-nut-sized, yellowish nodules occur 

 in the vaginal walls often near the vulva. 



(i) Testes. — ^There appears a non-painful, firm swelling 

 of the epididymis, later the testes become enlarged forming 

 a swelling of considerable size. Hydrocele is a common 

 attendant and perforation with pus discharge is not uncom- 

 mon. 



Swine. — As a rule there are no clinical symptoms of 

 diagnostic value. The disease may involve: 



(a) The Lymph Glands, especially those of the throat, 

 neck and prescapular regions (submaxillary, pharyngeal, 

 prepectoral, etc.). In pronounced cases a firm, nodular, 

 non-sensitive swelling of the throat and neck appears which 

 may be extensive enough to interfere with mastication and 

 the movements of the head. Occasionally fluctuation and 

 perforation with the discharge of thick pus or cheesy masses 

 occur in some part of the swelling. A tendency for fistulee 

 to remain is noted. 



(6) Lungs. — The symptoms are much like those of the 

 pulmonary form of hog-cholera and consist in cough, dyspnea, 

 emaciation, anemia, cachexia and death in about one month.
