184 GENERAL SYSTEMATIC BACTERIOLOGY 



The ascription noted by Enlows has not been found. 

 Artho-Spirobacterium. Enlows (1920, p. 88) states: 



Arthro-Spirobacterium : Klebs, 1887. 



Die Allg. Path., Jena, 1887, p. 88. In a resume of Hueppe's classification, 

 Klebs gives this spelling, and cites the 1881 edition of Hueppe's Die Formen d. 

 Bakt. 



Arthrospirobakteriaceen. A name used by Hueppe (1896, p. 146) 

 to designate a "Gattung" of bacteria in which the cells are spiral, 

 and which produce arthrospores, or at least do not produce endospores. 

 One " Untergattung " only, Spirochaeta, is included. The name is 

 evidently invalid, or at most, a casual family designation. 



Arthrostreptococcus. A variant (in proper form) of Arthro- 

 StreptokokkiLS q.v. 



Arthro-Streptokokkus. A sub-generic name proposed by Hueppe 

 (1886, p. 144) to include those bacteria with spherical cells, occurring 

 in chains in indefinite zoogloea, and without endospores. It is based 

 upon a misconception of morphology, it is not spelled as a Latin word, 

 no species are definitely assigned to it, and it is essentially synonjnnous 

 with Streptococcus. 



Ascobacillus. Apparently first introduced as a casual name by 

 Edington (1887, p. 1265) for an organism found in the blood of a 

 patient with scarlet fever. De Toni and Trevisan (1889, p. 1034) under 

 "species quod genus dubia" give Edington's "ascobacillus of Scarlet 

 Fever" as a synon^nn of Klebsiella Edingtoni Trevisan. The follow- 

 ing description is given. 



Baculis cylindraceis, tenuibus, 0.8/t longis, 0.2/Lt latis. Sporae pluries centum 

 in capsulis, quam baculis multo amplioribus, lucanicaeformibus contentae. 

 Hab. in squamis et sanguine hominum scarlatina laborantium. In culturis 

 gelatinamo lente liquefacit; coloniae flavae. 



Enlows (1920, p. 16) says 



Small rods, 0.8iu long by 0.2^ broad, often dumb-bell shaped, made up of long 

 ovoid spheres. Spores are contained in large sausage-shaped capsules many 

 hundred times larger than the bacilli themselves. Found in the blood of a 

 patient dying of scarlet fever. 



As a generic designation Ascobacillus was first used by Unna and 

 Tommasoli (1889). The name first appeared (p. 15) as Ascobacillus 

 citreus in a list of organisms isolated from the skin. Later (p. 60) 

 the organism is more adequately described.
