Bacillus flavo-aurantiacus sporogenes.* — W. N. Klimenko has 

 isolated from Lisle's antisyphilitic serum a bacillus that forms spores, 

 and stains by Gram's method. It coagulates milk, producing an acid 

 reaction ; it forms orange-yellow colonies on mannite agar, yellow 

 colonies on simple agar ; it exhibits a brownish-yellow pigment when 

 grown on potato ; it is not pathogenic for animals. The organism is a 

 long motile bacillus with rounded ends, and 10-20 flagella distributed 

 over the surface. The spore is oval and usually central. The optimum 

 temperature is 37° C. When grown on gelatin the medium is liquefied ; 

 broth is at first clouded, but later a fine pellicle forms at the surface, and 

 there is a slimy yellow deposit ; old broth cultures have a cheesy odour ; 

 on Petruschky's medium after 24 hours there is a production of acid, 

 but later (72-96 hours), it shows an alkaline reaction. Media containing 

 methylen-blue are not decolorised ; there is no formation of indol.
