320 SUMMARY OF CURRENT RESEARCHES RELATING TO 



that the bacilli have a universal distribution throughout the tissues and 

 organs, and are not limited to leprosy cells. The paper is interesting 

 on account of the excellent illustrations. 



Morphology of the Glanders Bacillus.*— Dr. G. Mayer injected sus- 

 pension of Bacillus Mallei into the peritoneal sac of guinea-pigs, and 

 found that this method of infection produced appearances indicative of 

 a true streptothrix, there being granules, club-shaped elements, and 

 branching filaments. 



Smegma Bacilli.f — Dr. L. Neufeld describes two acid-fast bacteria, 

 which inhabit the smegma of man and other animals. One has a strong 

 resemblance to the bacillus of tubercle, and the other to that of diph- 

 theria. The latter is probably identical with the Czaplewski-Laser 

 smegma bacillus. 



Micro-organism of Distemper and Distemper Vaccine.^ — Dr. S. M. 

 Copeman states that the specific organism of distemper is a coccobacillus, 

 which stains with ordinary anilin dyes, but not by Gram's method. It 

 is cultivable on the ordinary media, but only with difficulty on potato. 

 Milk is not coagulated, gelatin is slowly liquefied. In broth cultures 

 it forms chains often of considerable length. Inoculation of pure cul- 

 tures on the nasal mucosa reproduced the disease in a mild form, while 

 subcutaneous injection resulted fatally. 



By heating a broth culture at 60° for half an hour, and subsequently 

 adding a small quantity of carbolic acid as a preservative, a vaccine is 

 obtained, 2 ccm. of which is apparently sufficient to protect pups weighing 

 ]L kilos. Observations as to the length of the protection are being 

 carried out on a large scale. 



Immunity of Mice to Micrococcus tetragenus.§ — Prof. A. Lode 

 corrects the commonly accepted opinion that the grey house mouse is 

 naturally immune to the Micrococcus tetragenus Gaffky. He shows that 

 these animals die of septicaemia when infected with M. tetragenus.
