BIO-CHEMICAL CHARACTERISTICS OF BACILLI. 



99 



The indol reaction (benzaldehyde method) was strongly 

 positive in seven days. 



It will be noted that only one of these organisms is quite 

 typical in its reactions as compared with the previous 

 tabulated results of standard types or cultures isolated 

 from sources where infection with some of the recognised 

 types might be presumed. 



All of these "pseudo gaertner " except Oase I. gave a 

 strong positive indol reaction. Four of them though at 

 first non-lactose fermenters, attack this sugar within a 

 week and clot milk. Two others attack lactose very slowly 

 though giving typical cameleonage on litmus milk. Two 

 others ferment salicin energetically and early. 



Notes on Certain Anaerogenes. 



The last Table No. IV. shows the biochemical reactions 

 of certain anaerogene organisms labelled suipestifer and 

 fowl cholera. They are of interest as being closely similar 

 to the strain found by Bainbridge which he assumed was a 

 variant Gaertner type. 



The principal resemblance to this type is the cameleonage 

 of milk and the non-fermentation of lactose.

 strains of Suipestifer- Fowl Cholera^ etc.
