274 GENERAL SYSTEMATIC BACTERIOLOGY 



Rivolta (1888, p. 1) says: 



"Nel N. 1 Maggio 1887 nel giornale I'AUevatore descrissi un microbo del gatto, 

 coccobacterium felis il quale, moltiplicandosi prodigiosamente nel sangue 

 delgatto, fu causa di una ma lattia letale," also "Coltivazione. Si semino il 

 contagio nell'infuso di carne peptone gelatina; si moltiplico bene ed il liquido 

 divenne torbido. Si semino pure il virus nel brodo di oarne di pecora per 

 conservarlo." 



Descrizione del virus. II virus venne studiato nel sangut de' conigli e nelle 

 culture ed e rappresentato da cocco-bacterini mobili in alto, in basso e qualcuno 

 suU' asse trasversale; sono formati da due cellule minime o da tre talor come fuse 

 insieme; quelli che si presentano all' osservatore per una delle loro estrem- 

 ita appaiono come micrococchi; sono un po' splendenti, della lunghezza di 

 0^^00142, altri sono piu corti ed alcuni pare che arrivino a 0™™00285. 



This organism was later named Bacillus felis (Riv.) Trev. by Trevi- 

 san (1889, p. 14). 



Klinger (1912, p, 188) described a Coccobacterium mucosum anaero- 

 hiuni from pus. The organism is an anaerobic gas producing rod or 

 coccus, growing only at blood heat and in serum medium. The generic 

 name is probably invaUd. 



Schmidt and Weis (1902, p. 10) again introduced the term for a 

 generic name with the species Coccobacterium prodigiosium (Ehren- 

 berg) S. & W. This is a synonym of the older Serratia q.v. 



Cocco-Bacterium. A generic name proposed by Rivolta (1888, p. 1) 

 for the species Cocco-Bacterium felis. See Coccobacterium. 



Coccogenae. A subfamily of the bacteria proposed by Trevisan 

 (1885, p. 92) to include all bacteria which have spherical cells, at least 

 some stage in their life history. The diagnosis is "Status unicus evolu- 

 tionis coccos sistens." It is the equivalent of the family Coccaceae 

 (q.v.) as commonly used. 



Later De Toni and Trevisan (1889, p. 1035) include the following 

 tribes: Ascococceae, Sarcineae, Streptococceae, and Micrococceae. 



Coccogene. A variant of Coccogenae used by Trevisan (1889, p. 26) 

 for the third suborder of Batteriacee. Four tribes, Ascococcee, Sai-- 

 cinee, Streptococcee, and Micrococcee were included. 



Coccoglia. A synonym of Zoogloea, introduced by Billroth (1874, 

 p. 7) to include those cocci which occur embedded in gelatinous slime. 

 It apparently is synonymous with Gliacoccos. It was not proposed 

 as a generic name, but as a growth form of his pleomorphic Cocco- 

 bacteria septica. It has not been used by other authors. 



Coccomonas. A generic name suggested by Orla-Jensen (1921, p. 

 268) in the following statement:
