SYMPTOMS OF TUBERCULOSIS IN SHEEP AND GOATS. 



The tubercles have been usually found post mortem in these 

 animals or as the result of experimental inoculation, and symp- 

 toms have not been well recorded. They follow the same order 

 as in the ox, weak husky cough, wheezing and other r^les in the 

 lungs, disorders of the digestive organs, swollen lymph nodes 

 and glands, and caseated products in those that were of some 

 standing. I have found these latter especially, in the region of 

 the throat in high bred rams kept in confined buildings or yards 

 and highly fed to prepare for letting or sale. These lose in vigor 

 and activity and scrofulous swellings form on the neck, head or 

 elsewhere and become rapidly caseated. In German abattoirs 

 tuberculous sheep proved o. i to 0.15 per cent. In Saxon goats 

 the percentage was 0.6. 



SYMPTOMS OF TUBERCULOSIS IN DOGS AND CATS. 



These follow in the main those of consumptive cattle. As the 

 infection generally enters with food, the early symptoms often 

 point to disease of the throat and alimentary tract, while the later 

 ones involve those of the respiratory organs as well. Impaired 

 and capricious appetite, debility, early exhaustion under exertion, 

 emaciation, sunken pallid eyes, apathetic expression of the face, 

 lack of life and gaiety, a knotted feeling of the abdomen if the 

 region is flaccid, and a tense fluctuating sensation if ascitic, with 

 usually enlargement of the superficial lymph glands are noticeable. . 



When the chest becomes affected there is the hurried breathing, 

 quickly encreased by exertion, panting, paroxysmal cough, 

 wheezing, and the various morbid riles in the chest, crepitant, 

 friction, creaking, blowing, cavernous, mucous, etc. On per- 

 cussion, flatness is detected in limited areas in a number of centres. 

 Expectoration is usually promptly swallowed and can only be 

 secured with difiiculty for examination. 



When tuberculous sores and fistulse occur in the region of the 

 throat or elsewhere, the evidence is patent and the bacilli can 

 easily be found in the discharges. 



In cats the course and symptoms do not materially differ. In 

 both animals the history usually shows the connection of house 

 life and the habit of eating after tuberculous persons.
