Hog" cholera, J. J. Weistek {T{j(li<clir. YeearUenijk. Maandbla(l,2D {1902), Xo. 4, 

 pp. 147-174). — The author outUnes in general terms the various forms of hog cholera 

 which occur, classifying these forms according to the organs which are chielly 

 affected. Notes are given by way of differential diagnosis l)etween hog cholera and 

 swine plague, and tlie effectiveness of various forms of serum tieatincnt which have 

 been recounnended is discussed. 



Combating" infectious diseases of pigs, A. van Leeuwex ( Tljihchr. ]'eeart.senijk. 

 Maamlblad, 29 {1902), Xo. 6, pp. 249-254) ■ — Attention is called to the ditticulties in 

 the way of a thorough and effective disinfection of premises after the prevalence of 

 infectious swine diseases. The governmental regulations may require certain methods 

 to be applied and remedies to be used in a given manner, but experience has shown 

 that even the most thorough application of the best disinfecting methods known is 

 not sufficient to destroy all the organisms which may be found in the l)uildings and 

 yards occupied ])y hogs, excei)t when the work is done in the most scrupulous 

 manner. 



Conference of government veterinarians on inspection of pigs and pig 

 products, "\Y. C. Qiinnell et al {Jour. Depf. Agr. Victoria, 1 {1902), Xj. 3, pp. 

 251-255). — During this conference resolutions were passed for the purpose of regulat- 

 ing the action of inspectors with regard to tuberculosis, actinotnycosis, parasitic 

 diseases, and post-mortem changes in pigs. It is recommended that in pig carcasses 

 affected with localized tuberculosis the affected parts only be removed, and the rest 

 of the pork be admitted for sale. It is fui-ther reconnnended that pigs affected with 

 the following diseases in any stage be condemned: Anthrax, hog cholera, septicaemia, 

 and pyemia. 



The method of treating hog's affected with the diamond skin disease in 

 abattoirs, Levy {Zhchr. Fkischu. Milchhyy., 12 {1902), No. S, pp. 234-237) .-^he 

 author gives a critical review of the opinions of different authors regarding the nature 

 of the diamond skin disease and its connection Avith swine erysipelas. It is frequently 

 observed that hogs which have been affected with the diamond skin disease are 

 immune to swine erysipelas and vice versa. The diamond skin disease is usually of 

 a light form, while swine erysipelas is fatal in a large proportion of cases. Both are 

 known to be caused by the same bacillus. The author believes that on account of 

 the frequent occurrence of this bacillus in the intestines of healthy hogs the present 

 methods of combating the disease are ineflicient. I 



Combating" g-landers in the horse, V. Babes {Ztschr. Hyg. u. Infectionskrank.y . 

 89 { 1902 ) , Xo. 2, pp. 217-282, pU. 2). — The author made an extensive series of experi- 

 ments which involved the consideration of all the various problems connected with 

 this disease, including the nature of mallein, the mallein reaction, behavior of evi-j 

 dently glanderous horses toward mallein, mallein injections in horses which do not 

 react in a typical manner, glanderous tubercles, the significance of the cessation of 

 mallein reaction, the reaction of horses which are affected with other diseases than j 

 glanders, and the influence of mallein upon the glanderous process and upon the^ 

 organism of the horse. j 



The results of these experiments may be stated as follows: The toxic substances 

 which are obtained by filtration and precipitation from pure cultures of glanders 

 bacillus in a manner similar to that of the preparation of tuberculin cause a specific 

 reaction in glanderous horses. More than 90 per cent of the 7,000 evidently glan- 

 derous horses, more than 30 per cent of the horses which had been in contact with 

 glanderous horses, and only 1 to 2 per cent of horses in herds which were not infected 

 reacted. The specific action of mallein appears with certainty, however, only in 

 rested, well-fed animals without fever. Low fever temperature occurring just pre- 

 vious to the injection or previous reactions do not interfere with the results of later 

 injections, provided that an interval of 8 days occurs between the two injections. 

 The failure of reaction after frequent injections does not indicate a cure of the disease
