Human tubercle bacilli with 1 goat were found to be avirulent; in another 

 they produced a swelling of the mammary gland with nodular formations. In 

 the latter case, however, the process receded in a few w^eeks, and when the 

 udder was sectioned nothing was found, although the lungs contained tuber- 

 culous foci. The lambs fed with the milk from this animal also showed a 

 I)ronounced tuberculosis of the alimentary tract and its nodes. 



This work substantiates the belief that bovine tuberculosis is more virulent, 

 than human tuberculosis. 



A contribution to the knowledge of intestinal tuberculosis in cattle, F. 

 Gruttner (Abs. in Berlin. Ticrdrztl. Wchnschr., 26 {1910), No. 13, pp. 283, 28^; 

 Vet. Rec, 22 (1910), No. 1138, p. 711). — In observations made at the Hamburg 

 abattoir, it was found that 40 per cent of the cattle which during life had 

 been suspected of tuberculosis were suffering from tuberculosis of the intestinal 

 mucous membrane. These animals represented 1.35 per thousand of all the 

 cattle slaughtered in Hamburg. 



The infection generally started in the last third of the small intestine, in the 

 submucous follicles — rarely in the mucous membrane proper. In addition to 

 these lesions in the small intestine the cecum contained tuberculous ulcers in 

 17 per cent of the cases and the colon in S per cent. In 25 per cent of the 

 cases no characteristic lesions were found on the outer aspect of the intestine. 

 The mesenteric glands were always affected and, in addition, a series of other 

 organs and their lymphatic glands are nearly always tuberculous, the lungs 

 being affected with particular frequency. This intestinal tuberculosis can not 

 be diagnosed with certainty in the living animals since suspicious symptoms,, 

 such as marked diarrhea, are often absent even in severe cases, and the bac- 

 teriological examination of the dung also generally fails to reveal it. 



Beport of the International Commission on the Control of Bovine Tuber- 

 culosis (Ottawa, 1910, pp. J/l). — This report was presented for the consideration 

 of the Dominion Public Health Conference, at Ottawa, October 12, 1910. 



Bovine tuberculosis legislation, M. H. Reynolds (Anier. Vet. Rev., 38 

 (1910), No. 1, pp. 37-.'/7). — In a study which the author made of the laws» 

 organization, and work now being done in the several States of the Union it 

 was found that " 25 States impose tuberculin test restrictions on importation ; 

 16 States have some provision for compensation; 14 States provide for testing 

 by the State, i. e., the State may test ; 17 States of the Union have provision for 

 compulsory reporting ; only 5 States have any provision for carcass salvage ; but 

 2 States have legal provisions for pasteurization of creamery skimmed milk, 

 although this is a most serious source of dissemination ; 1 has state meat in- 

 spection service; 2, possibly 3, are attempting to control the distribution and 

 use of tuberculin ; 17 States have no special provisions referring to tuberculosis ; 

 and 21 States of the Union are not even pretending to do anything with the 

 great problem of bovine tulierculosis." 



Some methods employed in northern Europe to control bovine tuberculosis, 

 V. A. Moore (Amer. Vet. Rev., 38 (1910), No. 1, pp. 48-55). — Investigations by 

 the author during the summer of 1909 of the methods employed for the control 

 of bovine tuberculosis in Denmark, England, Germany, and Holland are briefly 

 reported. 



The so-called Bang method practiced in Denmark was found to be quite as 

 effective in small as in large herds. The method is generally considered by 

 cattle owners in Denmark to be entirely satisfactory, and if carefully applied 

 to give the desired results. The increased profits accruing to those who have, 

 sound herds is tending to bring more and more farmers to apply the method.
