VETEEINARY MEDICIXE. 789 



"Animals are easily immiiuized against swine plague bacteria by injection of 

 sterilized cultures, the immunizing substance being resident in the bodies of the 

 bacteria and not in solution in the tluid. 



" Immunity against virulent hog cholera bacilli is safely and uniformly pro- 

 di'.ced by inoculation with living cultures of naturally feeble virulence, but hot 

 b.v sterilized cultures. 



"This double vaccination has not proved of practical value in the control of 

 natural outbreaks in hogs." 



Some original notes on the comparative immunizing properties of vac- 

 cine and aggressin in Schweineseuche, F. S. H. Baldrey {Jour. Troi). Vet. 

 IScL. J (1910). No. 7. lip. J/G-ol. chart 1). — A brief report of experiments. 



Spiroptera strongylina, B. F. Kaupp (Mo. TaUey Vet. Bui., 4 (1910). No. 

 11. i>i). 2'J-ol. ptj.s. .'/). — This nematode is reported to have been taken from the 

 stomach of hogs raised in the Missouri Valley. This is thought to be the first 

 report of its occurrence in the T'nited States. 



Some notes on equine filariasis, E. P. Argyle (Jour. Trop. Yet. HcL, 5 

 (1910), Xo. 1, pp. 96-100). — Several cases are here reported. 



Canine piroplasmosis in Tonkin, C. Mathis (Bui. Soc. Path. Exot., 2 (1909), 

 Xo. 7, pp. 3S0-383; (ih.«. in Jour. Trop. Vet. Sci., 5 (1910), Xo. 1, pp. 201, 

 202). — The author states that in Asia this disease is known in India and 

 China. He now records its occurrence in Tonkin at the veterinary infirmary at 

 Hanoi, where it has often been found in both indigenous and imported dogs. 



The drug treatment of canine piroplasmosis, G. H. F. Nuttall (Parasi- 

 toJdiiii. 2 U!)09). Xo. If, pp. 409-.'i3.'i). — Some earlier work on the subject by 

 ItJilian investigators is reviewed, and further experiments with dyes, including 

 brilliant green, benzopurpurine, and Congo red, are reported. 



It was found that the first two of these dyes exert no injurious effect upon 

 the parasite and that the piroplasms multiply in the usual manner up to the 

 iinie of the animal's death. The three experiments with Congo red, howeAer, 

 demonstrate very clearly that the dye exerts a direct effect upon the parasites. 



Protocols are presented relating to the continued infectivity of the blood of 

 Cogs described in an earlier paper (E. S. R., 21, p. 488). The author concludes 

 that it is evident from these experiments that the parasites persist in the blood 

 of dogs which have recovered from an acute attack of piroplasmosis in con- 

 sequence of treatment with trypanblau and trypanrot. 



The results obtained from the use of trypanblau by Jowett in South Africa 

 (E. S. R., 22, p. 582) are briefly summarized. A summary with conclusions is 

 also given of the results of experimental treatment of canine piroplasmosis by 

 various authors. Trypanblau and tryjianrot appear to be the only drugs that 

 have definite preventive or curative action. 



Contagious gastro-enteritis in dogs, S. H. Gaiger (Jour. Trop. Vet. Sci., 

 ') ( 1910). Xo. 1. pp. 52-56, charts 5). — The al)ove name is given to a severe and 

 absolutely fatal disease among dogs in Lahore which is here described. 



The author has known the disease for the last 3 years, but not until the last 

 few months has it caused such losses. It is estimated that during this time 

 one-third of the better-class dog population has been wiped out. The pariah 

 dog is immune, or carries the disease in a chronic form. " Examination of 

 fresh mucus from the gastro-intestinal tract shows amebae in fair numbers, 

 l)Ut no difference has been noted l)etween these amebae and the amebae found 

 in healthy dogs' feces. The disease is most probably conveyed from dog to dog 

 by ticks."
