SuMMARY. — The advantages of this médium are : 



1. The simplicity of its préparation ; 



2. The rapidity with which the streptococcus grows in Ihis médium, 

 vrhich enables it to outgrow micro-organisms wilh which it may be 

 associated in wounds ; 



3. The conservation oF sporulating types of micro-organims, both 

 anaerobic and aérobic which enables later isolation by heating and 

 seeding on and into appropriale média. 



A. The production of characteristic reactions which makes possible 

 early tentative diagnosis of some of the most important anaerobes 

 présent in wounds, such as : 



a) The production of gas in 12 to 26 hours after inoculation plus the 

 présence of a non-motile, encapsulated Gram positive Bacillus indica- 

 ting the B. Welchii. 



h) The formation of clostridia plus Ihin, Gram positive motile fila- 

 mentous forms indicating the Vibrion septique ; 



c) Blackening of the liver with digestion of the inter-lobular connec- 

 live tissue and the présence of subterminal spore-bearing motile bacilli 

 indicating the présence of B. sporogenes ; 



d) The same findings in the présence of terminal ?pore-bearing 

 bacilli indicating either B. putrificus or B. letani.
