GENERAL SYSTEMATIC BACTERIOLOGY 491 



Khoury (1902, p. 65) also by Guerbet (1906, p. 495). Olson-Sopp 

 (1912, p. 9) described a Streptobacillus taette from Norwegian slimy 

 milk. 



The name is rejected by Erwin F. Smith (1905, p. 174). 



The nomenclatural status of Streptobacillus as a generic name is 

 questionable. The various organisms described are for the most part 

 quite unrelated. Technically perhaps Streptobacillus terrae may be 

 considered the type, as the first organism described for which a bino- 

 mial nomenclature was used. 



Streptobacter. A subgeneric name used by Schroeter (1886, p. 

 157 ff.) for seven species of the genus Bacillus, among them Bacillus 

 erythrospora, B. subtilis and B. anthracis. All the species so desig- 

 nated are characterized by formation of chains of rods. This name 

 has apparently not been used by other authors. 



Streptobacteria. A name used by Bilh-oth (1874, p. 18) to desig- 

 nate a growth form of his pleomorphic Coccobacteria septica, in which 

 the organism occurred as rods in chains. He also used it in the com- 

 bination Streptobacteria gigas-pericardii (1874, p. 60) for an organism 

 found in pericardial exudate. De Toni and Trevisan (1889, p. 945) 

 give the following description of the species. "Baculis cylindricis, 

 rectis, rigidis, apicibus rotundatis, 3.25-4 x 1.25, subinde in filamenta 

 brevia dispositis; sporis microsomis." These authors term the species 

 Bacillus gigas. The name is rejected by Ei-win F. Smith (1905, p. 

 174). VuUlemin (1913, p. 519) stated that the genus should not be re- 

 tained because the parallelism of planes of division is characteristic 

 of all rod-shaped organisms. 



Streptobacterium. A variant of Streptobacteria used by INIaggi 

 (1886, p. 84) to designate a growth form of Bacterium aceti Zopf. 

 It was also used by Billet (1890, p. 23) as a form genus to designate rod 

 shaped organisms which occurred in chains. Later it was used by 

 Jacque and JVIasay (1912, p. 180) in a generic sense in the combination 

 Streptobacterium foetidum. The organism described is a short rod, 

 with rounded ends, a "coccobacillus." It is actively motile, and does 

 not form spores. In bouillon cultures there is a marked tendency to 

 the production of long chains. It stains readily, is Gram negative, 

 and with dilute stains shows polar staining. The organism is faculta- 

 tive, grows readily in culture media, produces gas from dextrose and 

 maltose, milk is not coagulated, liquefies gelatine and sermii, and pro- 

 duces a foetid odor in cultm-e media. The organism described is 

 apparently close to Proteus.
