INFLUENCE OF DISEASE UPON MILK 77 



the products (meat and milk) of tuberculous animals. 

 The investigations were therefore largely directed along 

 these lines. The present views of those who have studied 

 the subject are fairly represented by the conclusions 

 reached by the British commission and published in 1911 

 after a careful and thorough inquiry extending over ten 

 years. These conclusions are as follows: 



" There can be no doubt that a considerable propor- 

 tion of the tuberculosis affecting children is of bovine 

 origin, more particularly that which affects primarily the 

 abdominal organs and the cervical glands. !And, fur- 

 ther, there can be no doubt that primary abdominal tuber- 

 culosis as well as tuberculosis of the cervical glands is 

 commonly due to ingestion of tuberculous infective 

 material." One hundred and eight cases of human tuber- 

 culosis other than lupus were examined by the Commis- 

 sion and bacilli of the bovine type were found in twenty- 

 four, or 22 per cent. The latter included sixteen cases 

 of primary abdominal tuberculosis, three of tuberculosis 

 of the cervical lymph glands, two of pulmonary tubercu- 

 losis, two of tuberculosis of the bronchial lymph glands 

 and one of joint tuberculosis. Bacilli of the bovine type 

 were found in nearly half of the fatal cases of primary 

 abdominal tuberculosis. 



The German commission made a study of fifty-six 

 different cultures obtained from cases of tuberculosis in 

 man and found six, or more than 10 per cent., to be of 

 the bovine type. 



Park and Krumwiede 5 determined the type of bacilli 

 present in 487 cases of tuberculosis in man and collected 

 from the literature the records of 1033 cases in which the
