784 EXPERIMENT STATION RECORD. I Vol. 41 



" Taking into consideration the post-mortem findings, tlie demonstration of 

 swine plague and hog cholera in a large percentage of the cases, and the results 

 from bacterin treatment, it would seem that necrobacillosis, Avhere the lesions 

 are internal, especially of the lung and intestines, is a secondary disease fol- 

 lowing swine plague and hog cholera. However, the local necrobacillosis, such 

 as bull-nose, necrotic stomatitis, canker of the feet, etc., may be a local lesion 

 primarily due to some abrasion of the skin or membranes, the necrophorus 

 bacilli and other ubiquitous organisms gaining entrance in that way causing 

 tissue necrosis." •

Ascarid infestation in swine, H. B. Raffenspeeger (Amer. Jour. Vet. Med., 

 H (1919), No. 8, pp. JfSS, Jt3Jt). — This is an address delivered before the Illinois 

 Veterinary ftledical Association in July, 1919, in which the author presents 

 data based upon investigations by the Bureau of Animal Industry, U. S. Depart- 

 ment of Agriculture. 



In considering the incubation of the egg of this ascarid it is stated that it 

 will develop to the infective stage in about three weeks at a temperature of 71° 

 to 77° F., and in about two weeks at a temperature of about 90°. The mortality 

 from infestation with the lung stage is greatest, especially in suckling pigs, 

 at the age of two to six weeks. In investigations made to determine the effect 

 upon pigs, one that survived infestation out of a litter of seven weighed 3.3 lbs. 

 30 days after the infestation, whereas each of the two control pigs v>'eighed 

 G5 lbs. Older pigs becoming infested stand a better chance of recovery. 



Recurrence of horse plag'ue (Amer. Jour. Vet. Med., IJf (1919), No. 10, pp. 

 494, 495, fifft. 3). — An outbreak of so-called forage poisoning or epizootic spinal 

 meningitis in the Aikansas Valley in western Kansas and eastern Colorado is 

 said to have resulted in the loss of a large number of animals. A brief statement 

 by A. T. Kinsley, who investigated the outbreak, is presented. 



Cerebro-spinal meningitis of the horse in Arg'entina (Vet. Rev., 3 (1919), 

 No. 3, pp. 29.'t-296). — This is a review of papers on the subject by Ligni&res, 

 Bossi, and Flores, respectively. 



Contribution to the clinical study of glanders in the mule, Cabay^, Colle, 

 and Lamakque (Rev. G^n. M6d. V^t., 28 (1919), No. 326, pp. 65-70; abs. in Vet. 

 Rev., 3 (1919), No. 3, p. £88).— Post-mortem examinations made of some 500 

 glandered mules and mallein tests of some 10,000 remounts in a Greek depot 

 led the authors to conclude that there are two forms of glanders in the mule, 

 namely, acute and chronic. 



A preliminary note on a new coccidium of rabbits, E. A, Bruce (Jour. Amer. 

 Vet. Med. Assoc, 55 (1919), No. 6, pp. 620, 621).— The author reports briefly 

 upon a new coccidium (Eimeria sp.) which infects the intestinal tract of the 

 rabbit in British Columbia. It is especially pathogenic for very young rab- 

 bits, often causing the loss of a whole litter. I\Iature animals are affected, 

 but appear to suffer no ill effects and may carry coccidia for several months. 

 It differs from previously described forms " in the extreme variation of the 

 size of its oocysts, the pinkish orange color of its larger oocysts, the excessive 

 formation of material for the oocyst wall, the pink color of its sporozoite 

 nucleus, and the presence of a very well-marlied globular residual body." 



Klein's fowl plag'ue, II. Van Stratten and B. .1. C. te Hennepi'e (Folia 

 Microbiol. [Delft], 5 (1918), No. 2, pp. 103-125, fig. i).— The authors discuss the 

 disea.se caused by Bacillus galUnariiin, which is of more importance to tlie 

 poultry industry in Holland than is fowl cholera, causing great losses in some 

 localities.
