792 EXPERIMENT STATION RECORD. 



On the presence of spirochetes in a case of hemorrhagic gastro-enteritis 

 in the dog, Lucet {Bui. Soc. Cent. Med. Vet., 87 (1910), No. 16, pp. 376-379, 

 figs. 2). — Photographs taken of the spirochetes concerned accompany the 

 account. 



Preliminary report on a new piroplasm (Piroplasma gibsoni n. sp.) found 

 in the blood of the hounds of the Madras Hunt and subsequently discov- 

 ered in the blood of the jackal (Canis aureus), W. S. Patton (Bui. Soc. Path. 

 Exot., 3 (1910), No. Jf, pp. 274-280, fiys. 2). — "This piroplasm differs markedly 

 in structure from Piroplasma canis; it is much smaller and is chiefly seen 

 as a delicate ring of blue staining protoplasm ; the pairs of large pyriform 

 bodies so characteristic of P. canis have never been seen." The method by 

 which P. gibsoni is transmitted in nature has not yet been discovered. 



The author also reports the discovery of two other species of Piroplasma, one 

 in the blood of the Indian mongoose and the other in the blood of the spotted 

 deer. 



Cutaneous filariasis in a dog, S. N. Mitter (Jour. Trop. Yet. Sci., 5 (1910), 

 No. 3, pp. Jfll-J/lS, pis. 2). — An attempt made to convey the disease, by inocula- 

 tion, to a healthy dog failed. 



Filaria medinensis in the dog, S. II. Gaiger (Jour. Trop. Yet. Sci., 5 (1910), 

 No. 3, pp. ^81-483). — Five cases in which this parasite was found in the dog in 

 India are reported. 



Contributions to our knowledge of fowl diseases, Ruther ( Ticrdrztl. Rund- 

 schau, 16 (1910), No. 5, pp. 41, 42; abs. in Berlin. Tierdrztl. Wchnschr., 26 

 (1910), No. 25, pp. 499, 500). — The results of pathological and autopsical find- 

 ings with cases of jaundice, spirillosis, coli infection, and leukemia are reported. 



Bird pest is not a contagious disease, E. Marchoux (Compt. Rend. Soc. 

 Biol. [Paris], 68 (1910), No. 8, pp. 346, 347).— The author on the basis of his 

 experiments states that this malady is not contagious, but is probably trans- 

 mitted by an intermetliary host and perhaps caused by a septicemic invisible 

 virus. 



Fowl cholera (Pasteurellosis), F. Raymond (Jour. Trop. Vet. Sci., 5 (1910), 

 No. 3, pp. 371-396, j)ls. 8, charts 14). — "The object of this pai)er is to demon- 

 strate that fowl cholera exists in Bengal; to reproduce in a series of pictures 

 the normal course of the disease in poultry and rabbits so that anyone can 

 recognize it; and to tender some practical advice in regard to prevention and 

 management of outbreaks in this Province." 



New investigations in regard to the relation of fowl diphtheria to fowl pox, 

 Uhlenhuth and Manteufel (Arh. K. Gsndhtsamt., 33 (1910). No. 2, pp. 288- 

 304, figs. 3). — A descriptive article, with the results of clinical and experimental 

 observations wliich show that fowl pox and fowl diphtheria are caused by 

 the same virus and that it is not due to a mixed infection. Typical pox lesions 

 could not be produced on the outer skin by intravenous injection of pox or diph- 

 theria lymph. The authors further state that for the present dove or pigeon 

 pox and fowl pox must be considered identical. 



Contributions to immunity against the so-called fowl pox, Manteufel 

 {Arb. K. Gsndhtsamt., 33 (1910), No. 2, pp. 305-312; abs. in Berlin. Tierdrztl. 

 ^Vchnschr., 26 (1910), No. 25, p. 499). — The virus used in this work was ob- 

 tained by scraping off the softened epitheliomje, or from the characteristic 

 membrane on the mucous membranes, and maceration of these with physiolog- 

 ical salt solution. Chickens infected intravenously or subcutaneously with, 

 these viruses showed an immunity which lasted from 1^ to 2 years. A hypoim- 

 mune serum was also produced by extending the injections over a much longer 

 period than is usually done, but this had no therapeutic effect when employed 

 in repeated doses of 5 cc. and also no jirotective action.
