Tuberculosis 



COMBINED TABULATION CASES REPORTED AND OWN SERIES OF CASES 



Mixed or double infections, 4 cases. 



Total cases, 1224. 



Conclusions. Bovine tuberculosis is practically a negligible 

 factor in adults. It very rarely causes pulmonary tuberculosis 

 or phthisis which causes the vast majority of deaths from tuber- 

 culosis in man, and is the type of disease responsible for the spread 

 of the virus from man to man. 



In children, however, the bovine type of tubercle bacillus causes 

 a marked percentage of the cases of cervical adenitis, leading to 

 operation, temporary disablement, discomfort, and disfigurement. 

 It causes a large percentage of the rarer types of alimentary tuber- 

 culosis requiring operative interference or causing the death of the 

 child directly or as a contributing cause in other diseases. 



In young children it becomes a menace to life and causes from 

 6J to 10 per cent, of the total fatalities from this disease. 



Prophylaxis. The prevention of tuberculosis in cattle is a matter 

 of vast sanitary importance. Not only have we to consider the 

 danger of infection from milk containing tubercle bacilli, but also 

 the inferior quality and diminished usefulness of milk and flesh
