64 SUMMARY OF CURRENT RESEARCHES liKLATING TO 



the Oospora pulmonalis of Roger and Sartory, but the biological and 

 morphological differences appear to he such as bo warranl the creation 

 of a new gpecies, to which the name Oospora bronchialis has been given. 



Bacterial Flora of Wounds.* — Doyen and Yamanouchi present a 

 prelimary note on their observations with regard to bacterial infecl 

 on the held of battle. Their investigations have been made principally 

 in relation to "gas gangrene," and they state thai they have invariably 

 found the Bacillus per/ringens associated with this condition. With 

 regard to treatment, their observations show that, provided the septic 

 focus receives early attention, excellent results may be obtained by the 

 application of compresses of " solution chloruree de liqueur de Labar- 

 raque " diluted to 10 or 20 parts per 1000. 



Bacterial Researches on Gas Gangrene. | M. Weinberg states 

 that in all the cases of gas gangrene that he has examined among the 

 British troops at the front, he has found a large Gram-staining bacillus, 

 which answers in all its morphological and biological characters to 

 Bacillus Welchii (B. per/ringens). This anaerobic organism was always 

 found to be associated with aerobes (or facultative anaerobes;, such as 

 B. proteus, staphylococci, and streptococci. A common combination was 

 found to be B. per/ringens, diplococci, and B. proteus. Although the 

 author admits that one is not able to state that all cases of gas gangrene 

 are due to the same organisms, yet he is of opinion that B. per/ringens 

 plays a very important part in the etiology of this condition. 



Ferment contained in Water. J — E. Voisenet has previously described 



an organism {Barillas amaracrylas) present in hitter wines, which, by 

 the action of an enzyme contained in its substance, is able to transform 

 glycerin into acrolein. Working with " Dijon water * inoculated into 

 a glycerinated mineral medium, he has produced abundant cultures of ;i 

 bacillus which presents the morphological characters of />. amaracrylis, 

 and. like it, is capable of dehydrating glycerin. The biochemical pro- 

 perties of the two organisms are, moreover, identical, and it is more than 

 probable that we are here dealing with one and the same bacillus. 

 Further researches with regard to the pathogenicity of the new strain 

 are being proceeded with. 



Bacillus bifidus in the Intestinal Cahal.§ — C. A. Kling endorses 

 the conclusions of Tissier with regard to the bactericidal action of 

 Bacillus Ufidus. The experiments were conducted with emulsions of 

 B. coli, B. I art is aerogenes, Proteus vulgaris, and Staphylococcus a arras. 

 and in every case the markedly inhibitory action of B. bifidis was mani- 

 fested. The inhibitory substance was found to be present in the culture 

 fluid, and was recoverable after filtration through a Chamberland filter ; 

 and also after dialysis. It was ascertained to be thermostable, and to ■
