Economics as a positive factor in the dissemination of tuberculosis in 

 animals, (). 10. Dvsom (.\(//. J'nirisiuncr, .i9 iHlOS), Xo. ,i(t, j))). HI, 31). — A iiajHT 

 read by the Jiutlior Ijeforc the IiitoniMliona! Cohgress on Tiil)ercul()sis, in vvliich 

 which are discussi'd tlie factors that have prevented a more effectual worli of 

 eradication. The aiithor considers eradication of the disease in tliis conntry to 

 depend upon the enactment and rigid enforcement of Federal laws which will 

 prevent the interstate shipment of any bovine intended for breeding or dairy 

 pui'poses unless submitted to the tuberculin test and authoritatively certified as 

 being free from the disea.se. 



The control and prevention of bovine tuberculosis in individual herds, 

 V. A. MooKK (Amn: 177. R< r., S', (JHOH), Xo. 1, pp. 22-29) .—Thin article forms 

 part of the report of the committee on diseases of the American \'eterinary 

 Medical Association. 



The author considers that past experience warrants the conclusion that 

 tuberculosis can be practically eliminated from cattle, not by acts of legislation, 

 but by the persistent application of an intelligent system of action that will pre- 

 vent the further spread of the virus and eliminate as quickly as consistent the 

 animals already infected. While laws will be of assistance, the real results 

 must come frt>m wise, conservative, and scientific advice given by the veteri- 

 narian and followed by the individual owner of cattle. 



The struggle against tuberculosis in cattle in Denmark, B. Bang ( Vet. 

 Rec, 21 {J90S). Xos. 10 ',6. pp. (),i-65 ; lO.'/l. pp. S2-S.J). — This is a paper pre- 

 sented at the International Congress on Tuberculosis held in Paris, in 1905. 



Suppression of tuberculosis among cattle on the Continent (Jour. Bd. Agi: 

 [London^. 15 (1908), Xo. 7, pp. .'t94-502). — A brief account is given of the work 

 in Sweden, Norwa.v. Denmark, Holland. Belgium, Germany, and France for the 

 suppression of tuberculosis in cattle. 



Bang's bacillus and its biology, J. Nowak (Ann. Inst. Pasteur, 22 (1908), 

 Xo. 6, pp. 5'fl-i')5lj. /W.v. .i). — The author here reports experiments carried on 

 with the bacillus which Bang described as the specific agent of epizootic abor- 

 tion in cows. A method of cultivating this bacillus which the author considers 

 surer and easier to carry out is described. Development has been obtained in 

 an atmosphere of oxygen and in comi)ressed air. The bacillus has lived in a 

 straight gelatin medium for more than 2 years. This viability explains the out- 

 breaks of epidenncs in certain stables. The death of the fetus resulted in 

 guinea pigs and rabbits inoculated subcutaneously, intravenously, and intra- 

 peritoneally with the bacillus. Neither the ingestion nor the introduction of 

 the bacillus into the vagina jiroduced the disease in these animals. Xo ex- 

 periments were made with cows. 



A contribution to the study of red dysentery (coccidian enteritis) of cattle, 

 E. ZuBLiN (Scfnoeiz. Arch. Tierheilk., 50 (1908), Xo. 3, pp. 123-169, figs. 10; 

 abs. in Vet. Rec, 21 (1909), Xo. 1072, pp. J,87, 7/8cS).— This is the report of an 

 extensive, study based upon the literature and the author's experience with the 

 disease in Switzerland. The disease is a febrile epizootic of young cattle that is 

 localized in the large intestine, particularly in the rectum. It is caused by a 

 specific coccidia known as Coceidium hovis. which is not found in healthy ani- 

 mals. Though generally terminating in recovery it may cause the death of 

 infected animals. 



Three stages of the infection are recognized: (1) The congestive stage in 

 which the feces contain blood coagula and a few coccidia; (2) the stage of 

 hemorrhagic diarrhea accompanied by fever; and (3) the stage of regeneration 

 and abatement and disappearance of the symptoms. Animals are probably 

 infected through solid food or fluids which contain the spores. Direct trans- 

 mission from animal to animal does not seem likely.
