852 CYCLOPEDIA OF LIVE STOCK AND COMPLETE STOCK DOCTOR. 



breathing is slightly more accelerated on exertion. The appetite fails 

 somewhat, the secretion of milk lessens or becomes more pale and watery. 



VI. Signs of Generalization of the Tubercle. 



In connection with this there come on signs of generalization of the 

 tubercle, such as irregularity of the bowels or enlargement or nodular 

 induration of some of the superficial lymph glands. Expectoration is 

 usually abundant. In the most advanced stages the symptoms are very 

 characteristic. The subject becomes thin and wastes visibly from day 

 to day. The hair is dry and erect which is most marked along the 

 spine, the skin is scurfy, rigid, and clings firmly to the bones, the eyes 

 are pale, deeply sunken in their sockets and bleary, the tears run over 

 the cheeks, while a yellowish, granular, fetid, and often gritty discharge 

 flows from the nose and drys in masses around the nostrils. The cough 

 is weak, painful, paroxysmal and is easily aroused by pinching the back 

 or the ribs. The breathing is liable to be hurried, even panting, and 

 the animal may stand most of the time with nose extended to obviate 

 the oppression that comes of recumbency. The visible mucosae is pale 

 and blanched and the pulse is weak and rapid. The temperature varies 

 from 103 to 105 degrees and the milk secretion is completely arrested. 

 In generalized tuberculosis the glands are enlarged, diarrha?a, and 

 clouded or blood stained urine. The morbid sound in the lungs has 

 become a complex variety in accordance with the nature of the lesion, 

 blowing, wheezing, amphoric, friction, creaking, mucous, with all con- 

 veyances from adjacent organs. Death usually occurs in a state of com- 

 plete marasmus, after months, or even years, of illness. 



Tuberculosis of the abdomen affects the intestines, mesenteric glands, 

 peritoneum, liver, spleen and pancreas. The generative organs some- 

 times suffer, in which case a persistent symptom is sterility. 



VII. Generative Tuberculosis. 



Generative tuberculosis in the bull is associated with an obvious swell- 

 ing. Veterinarians classify tuberculosis of the cow into Genital Tuber- 

 culosis, Mammary Tuberculosis, Pharyngeal Tuberculosis, Cutaneous 

 Tuberculosis, Glandular Tuberculosis, Tuberculosis of the Brain and 

 Meninges, Tuberculosis of the Eye, Tuberculosis of the Heart, Pericar- 

 dium or Pleura, and Tuberculosis of the Bones and Joints. The latter is 

 more common in calves and gromng cattle, but may be present at any 

 age. The essential for the unprofessional stock owner is to know the 

 causes, the prevention, the methods of amelioration, and how to know 

 the disease when it exists as here outlined. With this knowledge he 

 must promptly secure the services of a competent veterinary surgeon. -
