Appendix III : * Many species of anaero- 

 bic, Gram-positive, non-spore-forming, 

 largely parasitic rods have been de- 

 scribed. These are similar in many waj's 

 to the species included in Lactobacillus. 

 Prevot has arranged these in the follow- 

 ing genera. Several are inadequately 

 studied and scarcely deserve recogni- 

 tion. Some, as indicated, may belong 

 in other genera, e.g., spore-formers 

 belonging in genus Clostridium. Some 

 species produce gas in sugar broths or 

 have other characteristics (e.g., motility) 

 that are unusual for the families that 

 include Gram-positive, non-spore-form- 

 ing rods. 



Genus I. Eubacterium Prevot 

 (Ann. Inst. Past., 60, 1938, 294.) 



Non-motile, straight or curved rods. 

 Usually occurring singly, in pairs or very 

 short chains. Never show branching. 

 Not capsulated. Gram-positive. An- 

 aerobic.
