288 EXPERIMENT STATION RECORD. 



The use of serum from im.inune hogs for combating hog cholera, M. Dor- 

 set (T'e^. Jour., 65 (.1909), No. J/IS, pp. ooO-oGJ/). — A report presented at the 

 Ninth International Veterinary Congress at The Hague, in Septeuil)er, 1909. 



Attention is directed to 3 factors upon which the success of the worlc depends, 

 namely, careful standardized serum, an efficient organization, and the com- 

 mencement of the work in the spring or early summer. 



The control of hog cholera, J. W. Connaway {Ann. Rpt. Mo. Bd. Agr., J,l 

 (1908), pp. 289-325, figs. 10; Missouri Bd. Agr. Mo. Bui., 7 (1909), No. Jf, pp. 39, 

 figs. 10). — An address before the Missouri Swine Growers' and Breeders' Asso- 

 ciation on January 6, 1909, in which preventive and curative measures are 

 discussed. 



An epidemic of horses due to a Trichophyton, M. Pecus and II. Sabouraud 

 (Rev. G&n. Med. Vet., 13 (1909), No. 15 'i, pp. 561-586, figs, i-)).— Pecus here re- 

 ports upon an outbreak among cavalry horses, in which 800 animals were 

 affected, and due to a new variety of Trichophyton (T. gypseum granulosum). 

 Cultural and inoculation studies of this parasite are reported by Sabouraud 

 (pp. 571-586). 



Canine distemper, its prevention and treatment by inoculation, Richter 

 (Die Hundestawpr. Hire Vorbciignng nnd Bchandlung durch Impfung. Dessau, 

 1908, pp. 211, pis. S; ahs. in Rev. Gen. Med. Vi^t., 13 (1909), No. 152, pp. Ji59, 

 Jf60). — During the course of the author's investigations in which antidistemper 

 serums were used, including those of Piorkowsky and Gans, and the vaccines 

 of Copeman, Phisalix, and of Jenner (cowpox), 140 dogs, ranging in ages from 

 a few days to several months, were experimented upon. From the results ob- 

 tained it appears that none of these possess any preventive or curative action 

 against distemper. 



A bibliography of 103 titles is appended to the work. 



Kala-azar in Madras, especially with regard to its connection with the 

 dog and the buf (Conorrhinus), C. Donovan (Lancet [London], 1909, II, No. 

 21. pp. l-'f05, 1^96). — In 1,150 dogs obtained from Madras and Georgetown, the 

 only parasites found were the so-called leucocytozoon of the dog, 94 being in- 

 fected by this organism. There was no certain evidence of Piroplasma (Babe- 

 sia) or Trypanosoma infection. In no case was Leishmania donovani found in 

 the spleen, and attempts to inoculate dogs with it gave negative results. See 

 also a previous note (E. S. R., 21, p. 183). 



It has been determined that the reduviid bug (Conorrhinus ruhrofasciatiis) , 

 recently suspected of having some relation to the causation of kala-azar, feeds 

 voluntarily on human blood, but attempts to procure the pullulation of L. 

 donovani in its guts have failed. 



The author has confirmed the discovery by Lafont ( see p. 251 ) , having found 

 the flagellates in the latex of EupliorUa piluUfera growing in Madras. He be- 

 lieves this flagellate to represent a new genus for which he suggests the name 

 Phytomonas. 



A new anaerobic spore-bearing bacterium commonly present in the livers 

 of healthy dogs, and believed to be responsible for many changes attrib- 

 uted to aseptic autolysis of liver tissue, S. B. Wolbach and T. Saiki (Jour. 

 Med. Research, 21 (1909), No. 2, pp. 261-218, pi. J).— Out of a series of 23 

 healthy dogs of all ages, both sexes, and representing many different types 

 (mongrel) killed during a period of 7 months, 21 yielded the same bacillus — 

 hitherto undescribed. In only one case did the liver contain any other kind 

 of micro-organism. 



The presence of this bacillus is in no way connected with the necroses com- 

 monly found in the livers of dogs (in this series in 15 out of the 23 dogs). It 

 is a large spore-bearing, nonmotile, nonencapsuled, nonpathogenic, faculative
