The artificial production of immunity to tuhorculosls appears to rest upon the 

 use of attenuated llvinj? tubercle bacilli. The possible danger from the use of 

 human tul)ercle bacilli in innnuniziny cattle is also discussed. 



Human and bovine tuberculosis, N. Raw (Bril. Med. Jour., 1906, No. 2381, 

 PI). 3.57, ./.7.S). — In a continuation of his studies on the relationship of human 

 and bovine tul>erculosis. the author finds repeated confirmation of liis previous 

 conclusion that there are two forms of tubercle bacilli, but that man is sul)ject 

 to both and may readily become infected particularly in childhood by drinking 

 tuberculous milk. The author believes that human tubercle bacilli do not 

 attack the ordinary lymphatic glands of the body but produce lesions chiefly in 

 the lungs. It is argued, therefore, that In most cases where the mesenteric 

 glands are affected the tubercle bacilli are of bovine origin. 



Experimental transmission of tuberculosis from man to cattle, A. Eber 

 (Ztsclir. FUisch ii. M ilvhhijg., IH {IHOii), \o. 7. i)i). 21S-223). — The material 

 used in the inoculation experiments reported in this paper came from tuber- 

 culous mesenterial glands of human origin. 



It is found possible by using this material in the inoculation of a bovine 

 animal and subsequently making a reinoculation from this animal into another 

 bovine animal to produce an acute miliary tuberculosis resulting in deatli 

 within <■> to 7 days. Similarly when the material was first passed through a 

 guinea pig and subsequently used for the inoculation of cattle death resulted 

 within 51 days. In a third case, bacilli of less virulence were obtained. 



It appears from these experiments that tubercle bacilli may be obtained from 

 liuman cases of tuberculosis which are equally as pathogenic as bovine bacilli 

 for cattle. The author argues, therefore, against the proposition of separating 

 human and liovine tubercle bacilli on the basis of differences in virulence. 



The origin of tuberculosis, J. Bongert {Dent. Tlerdrztl. Wvhnschr., 14 

 il'JOU). \(). 21. Pit. 2.'tl-2.'i4) . — During the investigations carried out by the 

 author it appeared that a diffuse tuberculous infiltration of the intestinal 

 nuicous membranes is often observed in cattle, and this trouble is caused by 

 greatly attenuated tubercle bacilli. These bacilli show great differences in their 

 morpholcjgical, cultural, and pathogenic properties. The author objects to the 

 statement of Schiitz that tuberculosis of cattle is always caused by the bovine 

 tyi)e of tubercle bacilli for the reason that the type found in cattle is by no 

 means constant. For example, highly virulent and greatly attenuated bacilli 

 may be found in the same case of tuberculosis. 



The relation between human tuberculosis and pearl disease of cattle, 

 Lydia Rabinowitscii (Berlin. Klin. Wchiischr.. 43 (1906), No. 2Jf, pp. ISJf- 

 188). — Summing up her investigations on the interrelation of human and bovine 

 tuberculosis, the author comes to the conclusion that man may become infected 

 with pearl disease, but thai the frequency of such infection is still undeter- 

 mined. A determined warfare against bovine tuberculosis is, therefore, neces- 

 sary not only in the interest of animal industry, but for the protection of human 

 health. 



The nutrition of animals and tuberculosis, I). Bonora (Gior. R. 80c. cd 

 Accad. \(t. It 111.. ■',.', (I'.xiC). No. 20. pp. Ji80-Ji8J,) . — The relationship between the 

 nutrition of animals and the development of tuberculosis is briefly discussed. 

 It is maintained that a rational system of feeding in which a liberal and well- 

 lialanced ration is useil should lie at the foundation of any system devised for 

 the control of tuberculosis. This reconnuendation was m.ade in the belief that 

 properly nourished animals are less susceptible to tuberculosis than those which 

 are suffering from malnutrition. 



The pathogenesis of tuberculosis, II. VallI^e (Conipt. Rend. Aead. Sci. 

 [J'uri.'sl. I'i2 {1906), No. 20, pp. 1101-1103). — The author has continued his
