686 EXPERIMENT STATION RECORD. 



• if Grips aud B. pyogenes hovis are ideutical. To simplify the nomenclature 

 it is recommended that the name Bacillus pyogenes be used. B. pyogenes and 

 the bacillus of abortion seem not to be closely related. In many animals B. 

 pyogenes forms pus, but not in dogs. It is possible to immunize small labora- 

 tory animals, dogs and calves, against B. pyogenes and to obtain from them 

 an immune serum, which contains agglutinins and bactericidal substances. 



Local phenomena in passive immunity toward swine erysipelas, A. 

 Jabotzky iCenthl. Baki. [elc.], 1. Aht., Orig., p, {1007), Xo. U pp. TT-SO, figs. 

 7). — It is an exceedingly difficult matter to determine whether there is present 

 in the blood and lymph of animals a soluble cytase. The experiments reported 

 by the author showed the great importance of the phagocytes in destroying the 

 bacilli of swine erysipelas. Even if there be a free solution of complement in 

 the body fluids, it takes little part in destroying the bacilli, since their destruc- 

 tion is brought about in the interior of the phagocytes. 



The source of Bacillus suipestifer, K. Grauert (Ztsetir. Infcctionskrank. ii. 

 Ihjg. Hdusticre, .3 (WOl). Ao. 1-2. pp. 21S-22-j). — In 7 out of 23 pigs in perfect 

 health and showing no evidence of hog cholera the author found bacteria 

 which could not be distinguished from Bacillus suipestifer morphologically, 

 biologically, or culturally. It appears, therefore, that this organism may^ome- 

 times occur in a nonvirulent form. 



The resisting power of Bacillus suisepticus and B. suipestifer, D. Erdus 

 aud E. KoPPAXYi {Ztscltr. Infectionskrank. u. Hyg. Haustiere. 3 (i.W7). Xo. 

 1-2, pp. 226-234>. — Bacillus suipestifer shows a much greater resisting power 

 to ordinary disinfectants than B. suisepticus. The author presents in a tabular 

 form the ccmiparative resistance of these two bacteria to alcohol, peroxid of 

 hydrogen, chloroform, formaldehyde, boric and other acids, lime, etc. Both 

 organisms are quite susceptible to the action of copi>er sulphate, lime, and 

 creolin. 



The etiology of hog cholera and swine plague, F. Hutyba (Ztschr. Jnfec- 

 ti>,ihskntnk. u. Hyg. l/niistirre, 3 [lUOl). Ao. 1-2, pp. 2.3.'j-2.'f3). — The author 

 holds the view that both the intestinal and i)ectoral forms of hog cholera are 

 due to a filterable virus but that pure swine plague is caused by BaeiUus sui- 

 Kepticus. 



Vaccination against swine plague, Beciier {Berlin. Tierdrztl. Wclinschr.. 

 I'.xn. Ao. 2',), pp. 551, 552). — The use of suptol gave good results in curing 

 all cases of swine plague except those in which an extensive degeneration had 

 already taken place in the lungs aud liver. The protective ix)wer of this 

 vaccine also proved to i)e relatively high. 



Hygienic defects of pigpens, K. Eveks {Ztsrhr. liifi ctionsknink. u. Hyg. 

 //itustiere. 3 {IHOD. Ao. 1-2. pp. 30-6S. figs. ]:>). — Details are given for the 

 SJinitary construction of farm buildings, particularly pigpens. The lack of 

 protection against cold and dampness is considered the chief defect of such 

 structures. The results obtained from vaccination exi)eriments to prevent hog 

 cholera and swine plague were unsatisfactory where the pens were cold and 

 damp. 



Annual report on the cases treated in the clinics of the royal military 

 farrier during 1906, E. Krcger [Ztsehr. Veterinark., lU {1907). Ao. fi-9 pp. 

 3-'i5-350.) — During the year under rei)ort 255 horses were treated for diseases 

 of the eye, alimentary tract, skin. legs, and feet. These diseases included 

 chiefly wounds of the eye, keratitis, flesh wounds, fistula, abscesses, herpes, 

 corns, toe cracks, quittor, etc. Brief notes are given on the treatment adopted 

 and the results obtained.
