1024 EXPERIMENT STATION RECORD. 



1'n-nii materia] thus obtained cultures were made of tubercle bacilli, and guinea pigs 

 were inoculated. A decided difference was observed between the treated and 

 untreated calve.-. The vaccination treatmenl had the effect of checking the progress 

 of tuberculous lesions and also of causing a distinct retrogression in these lesions. 

 The tuberculous foci in treated animals were strongly encapsulated, although they 

 contained living tubercle bacilli. It is believed, however, that such bacilli would 

 never have escaped from the capsules. The treatment is believed, therefore, tn have 

 had a distinct curative effect. The authors considered it uncertain what would be 

 the effect of this treatment upon older animals. 



The cure and prevention of bovine tuberculosis — subcutaneous injections 

 of oil, T. B. Keyes {Amer. Vet. Rev., 28 (1904), No. 5, pp. 419-431).— The author 

 presents a discussion of his method of treating human tuberculosis by means of injec- 

 tions of olive oil. The oil is used in a pure and thoroughly sterilized condition. It 

 is believed that the same method may he profitably employed in treating tuberculi »sis 

 in domesticated animals. 



Tuberculosis as the chief defect in food animals, Plate and J. Keuten i Ztschr. 

 Fleisch- a. Milrhln/;/., \:> (1904), No. .', pp. SSS8). — The purpose and meaning of the 

 < rerman imperial meat inspection laws regarding the method of procedure with tuber- 

 culous meat are briefly discussed. Attention is called to the desirability of possess- 

 ing regulations which are as detailed as possible regarding the extent of tuberculous 

 infection which renders necessary a total condemnation of the carcasses. 



Bovine tuberculosis, V. A. Moore {New York Cornell Sta. />'"/. 225, pp. 7? 92, 

 ri'i*. 8). — In this bulletin a general, popular account is presented of the cause, meth- 

 od- of infection, period of incubation, course, detection, and prevention of tubercu- 

 losis. The approved methods of eradicating tuberculosis from a herd are described 

 in some detail. 



Avian tuberculosis in its relation to mammalian tuberculosis, Lydia E&ab- 

 inowitsch (DeuL Med. Wchnschr., 30 (1904), No. 46, pp. 1675-1678) . — The literature 

 relating to this controversy is briefly reviewed. The author made post-mortem 

 examinations on 200 birds and found tuberculous lesions in 55 of this number. 

 Experiments were carried out not only on the tuberculosis of domestic fowls and 

 pigeons, hut also on this disease in various species of birds during which .'!4 distinct 

 cultures were employed. Apparently, according to the author's observations, the 

 danger of transmission of tuberculosis in birds from close association is very slight. 

 Attention is called to the possibility of infection of fowls through the egg. The 

 author undertook experiments t" gain information on this subject. During these 

 experiments 32 eggs were inoculated with tubercle bacilli from different sources and 

 from this number of eggs only S chickens were hatched. About 90 per cent of the 

 embryos in the eggs inoculated with avian tubercle bacilli failed to hatch, T* > per 

 cent in those inoculated with human bacilli, and 40 per cent in those inoculated 

 with bovine baeilli. The avian bacilli were therefore considerably more virulent 

 in these cases than the mammalian form of the organism. The author believes 

 as a result of her investigations that avian tuberculosis is identical with the bovine 

 form of the disease. 



Tuberculosis in ducks, \V. E. Kim. (Amer. Vet. Rev., ?8 (1904), No. /', /</». 361- 

 363). — Brief notes are presented on the symptoms and relative frequency of tubercu- 

 losis in chickens and ducks. In an outbreak of this disease an examination was 

 made of various organs from affected ducks and a micro-organism was obtained 

 which closely resembled that which was observed in chickens affected with 

 tuberculosis. 



Pseudotuberculosis in buffaloes, A. Padrone \<iii>r. R. Soc. Accad. Vet. Rah, 53 

 (1904), A*". 43, /'/'. 1009, 1010). — Pseudotuberculosis was observed in a buffalo which 

 was killed for meat and which came under inspection at an abattoir. The disease 

 affected chiefly the lungs. From the pathological tissue cocci and diplococci were 

 obtained.
