212 GENERAL SYSTEMATIC BACTERIOLOGY 



Two subtribes were included, namely, Eubacterieae and Sarcineae. 



Buchanan (1918, p. 39) recognized this tribe as the second of the 

 family Bacteriaceae, with four subtribes Fusiforminae, Hemophilinae, 

 Rhizohiinae and Bacteriinae. The description is: "Cells rod-shaped, 

 never spiral nor strictly filamentous; single or in chains, motile or non- 

 motile, never producing endospores, either Gram-positive or -negative." 



Bergey et al. (1923, p. 194) used this designation (with the spelling 

 Bactereae) for the sixth tribe of the family Bacteriaceae with the follow- 

 ing description: "Gram negative rods generally growing well on arti- 

 ficial media. Generally attack carbohydrates forming acid and often 

 gas composed of CO2 and H2. When motile, the flagella are peritrich- 

 ous." Six genera are included. 



Bacterien. A casual name used by Cohn (1872, p. 132) and sub- 

 sequent German writers for the bacteria. 



Bacteries. A casual name used by Davaine (1863) and subsequent 

 French authors for the group bacteria. 



Bacteriinae. A subtribe of the tribe Bacterieae named by Buchanan 

 (1918, p. 47) with the following diagnosis: 



Cells not fusiform, rod shaped; not hemoglobinophilic; aerobic, facultative, or 

 microaerophilic; not securing growth energy exclusively by the oxidation of 

 carbonaceous compounds. Spores never formed. Motile or non-motile. 



It included the following genera: Pseudomonas, Serratia, Chromo- 

 bacterium, Pasteur ella, Bacterium, Proteus, Pfeifferella, Lactobacillus, 

 Erysipelothrix, and Corynebacterium. 



Bacterina. A group created by Perty (1852, p. 179) to include the 

 genera Bacterium, Vibrio and Metallacter. The name has never come 

 into common use. 



Bacteriopsis. A generic name proposed by Trevisan (1885, p. 103) 

 for a group of bacteria. The organisms were considered as showing 

 three stages of development: 1. Bacilli. 2. Filaments. 3. Cocci. 

 The bacillus form was regarded as most typical. The cells were short 

 cylindrical or ellipsoid, straight, not articulate, colorless or colored, 

 showing both macrobacilli and microbacilli; cytoplasm equally diffused 

 in cells. Spores none or unknown. 



The species included in the genus are as follows : 



Bacteriopsis Rasmusseni = Leptothrix I Rasmussen. 

 Bacteriopsis aceti = Mycoderma aceti Pasteur. 

 Bacteriopsis Pasieuriana = Bact. Pasteurianum E. Chr. Hansen. 

 Bacteriopsis merismopedioides = Bact. merismopedioides Zopf.
