A Non-Gas-Producing Strain of the Hog-Cholera Bacillus Isolated from 

 an Old Laboratory Culture. C. Tenbroeck. Jour. Exp, Med., 

 1916, 24, 213-222. 



In a stock culture of the hog-cholera bacillus, which was passed 

 through a series of rabbits 14 years ago, an organism was found that 

 differs from the original culture in that it fails to form gas from the 

 carbohydrates that are usually attacked by this organism, while acid 

 formation persists. This new strain is agglutinated by an anti-hog- 

 cholera bacillus serum and produces in rabbits and mice a disease simi- 

 lar to that caused by the typical cultures. The failure to form gas has 

 persisted over a period of 18 months and all attempts to cause the 

 strain to revert to the original condition have failed. It resembles in 

 many respects Bacillus typhi and it may be that some of the so- 

 called typhoid cultures that are not agglutinated by antityphoid 

 serum are non-gas-producing paratyphoids. Attempts to produce a 

 similar change in a more recently isolated culture of the hog-cholera 

 bacillus by means of animal passages and changes in the environment 

 have been negative. — B. W.

The Wassermann Reaction in Two Hundred and Fifty-one Tuberculous 

 Dispensary Cases. W. R. Jones. Med. Record, 1916, 90, 418-419. 

 Of 251 cases examined in the tuberculosis clinic, 73 gave a positive, 



and 178 a negative Wassermann. — M. W. C. 



Autotherapy in Poliomyelitis. C. H. Duncan. New York Med. 



Jour., 1916, 104, 342-343. 



Report of a case of poliomyelitis treated by the hypodermic injection 

 of the spinal fluid removed from the patient. — M, W. C.

S. Flexner. Jour. A. M. A., 1916, 67, 583-584. 



A review of the work already reported from the Rockefeller Insti- 

 tute on the serum treatment of infected monkeys, and the work of 

 Netter on the treatment of human poliomyelitis with the serum of

Vaccine Therapy and Other Treatment in Acne Vulgaris and Furuncu- 



losis. H. H. Fox. Jour. A. M. A., 1916, 66, 2064-2067. 



From an analysis of 100 cases it would appear that the treatment 



of these conditions by vaccines, either autogeneous or stock, does not 



effect as high a percentage of cures as do other therapeutic measures.
