Tuberculosis of man is transmissible to cattle, TnoMAssuN {Rec. Med. Vi't.^ 

 Paris, s. ,svT., cV [I'.ioi), N(i. 17, pp. i'>..'9-'>.}S). — A rritical review of the recent litera- 

 ture of this sul)ject is presented by the author. Inoculation exiK-riments were made 

 lui 2 calves and 2 two-year-old heifers, during which tul)ercle l)acilli of human origin 

 were ii.sed. The bacilli came from cases of tubercular meningitis, tubercular arthri- 

 tis, and tuberculous kidneys. Hypodermic intraperitoneal and intratracheal inocu- 

 lations were made. Great care was exercised to be certain that the animals were 

 not infected with tuberculosis before the experiments began. In only one case was 

 a generalized form of tuberculosis developed. In one other of the 4 experiments 

 local tu])eri-ular lesions were produced. The author concludes from these exjwri- 

 nients that it is ditlicult but not impossible to produce tul)erculosis in cattle by 

 means of pure cultures of tul)ercle bacilli fi'oni man. It is considered, therefore, 

 that tuberculosis of man and of cattle are identical. The author believes that the 

 transmission of tuberculosis from cattle to man is much easier than that from man 

 to cattle, on account of the greater virulence of tubercle bacilli of bovine origin. It 

 is urged, therefore, that the precautions which have usually been recommended 

 should still be observed in preventing the transmission of tuberculosis to man 

 through the medium of infected milk and meat of tuberculous cattle. 



The communieability of human tuberculosis to cattle, S. DELEPniNE {British 

 Mid. Jour., lUOl, Xo. 2130, ])p. 1JJ4-I-',.'G) . — The author undertook inoculation experi- 

 ments for the purpose of determining whether tuberculosis could be transmitted from 

 man to animals. The material which was used for inoculation was prepared ]jy mix- 

 ing the sputum of 6 tuberculous patients. The bacilli in the sputum from different 

 j)atients were of different types, including long slender forms, thick, uniformly stain- 

 ing forms, and short forms in clumps. As experimental animals the author made 

 u,se of 4 calves which were apparently healthy, but which were not i)reviously tested 

 with tuberculin. One of the calves was inoculated directly into the lung, the second 

 subcutaneously, the third into the peritoneum, and the fourth was fed 2 qts. of 

 milk containing ten times as much tuberculous material as the other calves had 

 received by inoculation. The lirst calf, which was inoculated in the lung with 5 cc. 

 of mixed tuberculous sputum, died on the sixth day of generalized tuberculosis, 

 which was not due to the inoculation. The second calf, inoculated with the same 

 amount of sputum, su))cutaneously, died on the sixth day with a conspicuous enlarge- 

 ment of the gland at a distance of 5 in. from the point of inoculation. This experi- 

 ment was considered of doubtful result. The third calf, which received 5 cc. of 

 mixed sputum in the body cavity, showed no definite reaction after 26 days, but 

 reacted (58 days after inoculation and exhibited, on post-mortem examination, mai'ked 

 tuberculosis of the peritoneum. The fourth calf, feil with 50 cc. of mixed sputum with 

 its food, died 2(5 days afterwards with tubercular lesions along the alimentary tract, 

 but no evidence of tul)erculosis in any other organ. 



Detailed notes are given on the history of each of these experimental animals. It 

 is stated that there was no evidence of any tendency toward resolution in any of the 

 tul>ercular lesions. They were all fresh and in a progressive condition, and the evi- 

 dence was considered conclusive by the author that the disease, in 2 of the 4 cases, 

 was communicated by feeding and inoculation into the peritoneum respectively. 



Tuberculosis in dairy cattle, J. p]. De.vn ( (^ureiisland Atjr. Jour., 9 {1901), No. 1, 

 pp. 1,::j-1.'4). — The author discusses the relationship of tuberculosis in dairy cows t<t 

 the disea.se in man. Attention is again «"alled to the fact that :{<i out of tlu; 40 cows 

 which composed the dairy from which the (|ueen and her househohl obtaineil milk 

 were found to 1)e tuberculous. The milk of this dairy was used freely, but no cases 

 of tuberculosis developed in any persons who use«l the milk. Cases are cited from 

 the literature of the subject which indicate the general healthful effect upon man
