TUBERCULOSIS OF THE COW 145 



cervical glands, or getting into the small intestine it may produce 

 several different lesions, such as ulceration of the gut, tuberculosis 

 of the mesenteric glands attached, and of the peritoneal covering. 

 The percentage of these cases of alimentary tuberculosis due to the 

 bovine tubercle bacillus is very large. Taking both classes of cases 

 (cervical gland and abdominal) together, numbering .38, there are 

 17 in which the bovine bacillus alone v^as found, 19 in which the 

 human bacillus alone was found, and 2 in which both were found. 

 Taking the primary abdominal cases alone it is seen that in 16 

 out of 29 the bovine bacillus was found; in 14 of these it was 

 the sole infective agent present. 



The German Tuberculosis Commission ^ examined 5 6 cases 

 of human tuberculosis, and in 6 of them found the bovine 

 tubercle bacillus as the cause of the tuberculosis. All the 

 findings were in children under seven years of age. The 

 nature of the cases was as follows : 2 cases of tuberculosis of 

 the mesenteric glands, and one each of the following — 

 abdominal tuberculosis with caseating mesenteric glands, cal- 

 careous tubercle of mesenteric glands with tubercles in spleen 

 and pleurae, general miliary tuberculosis, including lungs and 

 meninges, acute miliary tuberculosis, involving practically all 

 organs. Out of 10 cases of primary intestinal and mesenteric 

 gland tuberculosis 5 were infected with bovine and 5 with 

 human bacilli, and of .3 cases of cervical gland tuberculosis 

 in children under ten 2 showed bovine and 1 human tubercle 

 bacilli. 



Eecently Oehlecker has studied the bacilli from 14 con- 

 secutive cases of primary cervical adenitis. Two cases were 

 in adults, and ia both of these cases human bacilli were 

 isolated. The remaining 12 cases were in children, and from 

 4 others the bovine tubercle bacillus was obtained. 



Lewis ^ studied the types of tubercle bacilli isolated 

 from 15 consecutive cases of tuberculous cervical adenitis. 

 In all cases the material was glands removed by operation. 

 Nine of the cultures were of bovine and 6 of human type. 

 Apart from modifications due to the age of the patients there 

 were no differences in the clinical or pathological picture. The 

 bovine bacilli were from patients 1-^ to 18 years old (average
