Vaccinating against tuberculosis in bovines with Tuberculosan (Burow), 

 KiRSTEiN (Deut. Landw. Pressc, 38 {1911), No. 90, p. 1021; ahs. in Molk Zty. 

 [Hildesheim^, 25 (1911), No. 98, pp. 18U, iS//5).— Practically the same ma- 

 terial as noted in the abstract above. 



In regard to therapeutic measures for tuberculosis in bovines, with 

 particular regard to Tuberculosan (Burow), T. Fleischhauer (Arch. Wiss. u. 

 Frakt. Tierheilk., 37 (1911), No. 3. pp. 2^3-270; abs. in Berlin. Tierdrztl. 

 Wchnschr., 27 (1911), No. ,'/5, p. 823). — Favorable results were obtained with 

 this preparation, and the author recommends a systematic study of its value. 



Contagious abortion of cows, W. J. MacNeal and H. W. Mumford (Illinois 

 ^ta. Bui. 152, pp. 530-5-'i3). — The purpose of this bulletin is the brief presenta- 

 tion of a number of facts which concern the cause, preventive measures, and 

 restriction and eradication of this disease, as established by the results of 

 recent researches. 



Bacteriological examinations were made of the afterbirths of 18 cows, of 

 which 6 appeared to be clinical cases of contagious abortion, and in 2 cases the 

 authors isolated the organism originally described by Bang and Stribolt. In 

 order to eradicate the disease from the herd the authors recommend that " the 

 affected cows should be isolated, and their genital passages cleansed once or 

 twice daily with an antiseptic solution until all discharge has ceased, when they 

 may be returned to the herd; all infectious material (afterbirth and dis- 

 charges) should be burned ; infected stalls should be cleaned and disinfected ; 

 the sheath of the herd bull should be cleansed with a disinfectant solution 

 before and after service, and a separate clean bull should, be used for heifers 

 and clean cows." 



The recommendations of the conmiittee appointed by the Board of Agricul- 

 ture and Fisheries of Great Britain to inquire into epizootic abortion of cattle 

 (E. S. R., 22, p. 584) are critically discussed, and the results of other investiga- 

 tors are reviewed. 



The complement fixation reaction in the diagnosis of contagious abortion 

 of cattle, W. P. Larson (Jour. Infect. Diseases, 10 (1912), No. 2, pp. 178-185).— 

 The conclusions drawn from the study here reported are as follows : 



" Contagious abortion of cattle in this country is caused by a micro-organism 

 identical with that causing the disease on the European Continent. The com- 

 plement fi.xatiou reaction is a reliable and accurate method of diagnosis. All 

 animals do not contract the disease, even if in an infected herd and living under 

 the same conditions as those which become infected. An animal may react 

 positively, indicating that she has at some period been infected, and yet may 

 not abort. This brings up the question of immunity, which will be the subject 

 of a future study." 



Filterable viruses, F. Loeeflek (CentU. Bakt. [efc], 1. Abt., Ref., 50 (1911), 

 Beiheft, pp. 1-12). — A survey of the diseases known to be caused by filterable 

 viruses and with particular reference to foot-and-mouth disease. 



Contributions to the etiology of foot-and-mouth disease, L. von Betegh 

 (Centbl. Bakt. [etc.'], 1. AM., Orig., 60 (1911), No. 1-2, pp. 86-90, i)ls. 2).— 

 The author observed in the contents of the vesicles cocci-like formations, the 

 smallest of which were from 0.25 to 0.3 ix and the largest 1 /n in diameter. 

 Many of these cocci were enclosed in leucocytes, and detected with the aid of 

 the dark field illumination apparatus. They are held to be the causative 

 organisms of foot-and-mouth disease.
