encapsulation ; and apparently there is no marked inflammatory reaction as 

 long as the cyst remains intact." 



Krafft's vaccination against swine plague, vo>f Lojewski (Berlin. Tierdrstl. 

 Wchnschr., 26 (1910), No. 43, pp. 829, 830).— The results obtained with 619 pigs 

 were considered good. 



Bacteria resembling paratyphoid B in the intestinal tract of the horse, 

 E. HuBER (Ccntbl. Bakt. [etc.], 1. AM., Orig., 56 (1910), No. 1, pp. i-28).— The 

 bacteria from the intestinal tracts of 100 horses which came to slaughter were 

 examined and compared with 15 strains of paratyphoid B (human and calf) cul- 

 tures, 5 of Bacillus suipestifcr, 1 of mouse typhoid, and 1 of B. enteritidis Gartner. 



The author concludes from his work that strains 2, 21, 23, and 34 isolated 

 from the intestinal tract of the horse, and which are agglutinable by para- 

 typhoid B and hog-cholera serum, as well as a noumotile strain, differ from the 

 bacteria of the hog cholera in the following respects: (1) Glycerin is decom- 

 posed by the horse strain (with the exception of a nonmotile one) with a rapid 

 evolution of acid and gas, whereas paratyphoid B and B. suipestifcr decompose 

 glycerin but produce only a small amount of gas; (2) the horse strains reduce 

 malachit green and orcein to a less extent than paratyphoid B and B. suipestifcr; 

 (8) less hydrogen sulphid is liberated by the horse strains; (4) no proteino- 

 chrom is produced by the horse strains; (5) indol is produced by the horse 

 strains but not by B. suipestifcr and paratyphoid B ; (6) the horse strains are only 

 slightly agglutinated and never to the limit of the titer. Normal horse sera agglu- 

 tinate them much more strongly than do the paratyphoid and B. sud-pestifcr strains. 



The bacteria from the hog-cholera group were only slight affected by sera 

 which were prepared from horse strains. The horse strains were therefore 

 characteristic of a distinct race, which on one hand partly resembles the 

 B. coli communis and on the other the paratyphoid B. 



Vaccination against equine influenza, Pommeich (Berlin. Ticrarztl. 

 Wchnschr., 26 (1910), No. ^2, pp. 811, 812).— The results obtained, noted after 

 8 months, were excellent. 



The diagnosis of rabies, J. Reichel (Amer. Vet. Rev., 38 (1911), No. 4, 

 pp. 447-472, figs. 4)- — The author, in addition to discussing the historical, patho- 

 logical, and clinical data, the rules regulating the examination and diagnosis 

 of rabies, and the laboratory procedure for detecting it, points out that more 

 heads were received in the laboratory for diagnosis during November and De- 

 cember than during the months of July and August — this finding being con- 

 trary to general opinion — and further, that no clinical case of rabies (with 

 symptoms) which he had under observation lived over 8 days. 



From the results of a microscopic examination of sections of the medulla 

 oblongata and ganglia, including one of the sympathetic ganglia and the plexi- 

 form ganglion of the pneumogastric nerves, it was found that Babes' rubid 

 tubercle " was not noted in the medulla oblongata of 27.5 per cent of rabid 

 animals. On the other hand, it was present in 5.8 per cent of the cases in non- 

 rabid animals. The proliferation changes of Vau Gehuchten and Nelis in the 

 sympathetic ganglia were present in 77.6 per cent of the authentic cases and in 

 4.2 per cent of the cases free of rabies. Of the rabid cases in the plexiform 

 ganglion 99.1 per cent were positive, and of the nonrabid cases, 12.9 per cent. 



Examinations for the presence of Negri bodies resulted in 9.6 per cent of 

 failures in positive cases. The greatest difficulty in detecting the bodies was 

 experienced with the horse. 



Fowl cholera and methods of combating it, P. B. Hadley (Rhode Island 

 Sta. Bui. 144, PP- 309-337, dgms. 3). — This summarized account of the disease 

 of poultry, caused by Bacillus bipolaris septicus and known as fowl cholera, in- 

 cludes a brief report of 2 exi^eriments involving the inoculation of the bacillus
