Genus 5. Staphylococcus Rosenbach 1884b, p. 19 



Synonyms: Micrococcus Cohn 1872 em. Migula 1894; Botryomyces 

 Bollinger 1888; Botryococcus Kitt 1888, not Botryococcus Kuetzing 1849; 

 Galactococcus Guillebeau; Bollingera Trevisan 1889; Gaffkya Trevisan 

 1885; Pyococcus Ludwig 1892; Carphococcus Hohl 1902; Albococcus 

 Winslow and Rogers 1906; Aurococcus Winslow and Rogers 1906; In- 

 dolococcus Jensen 1909; Liquidococcus Jensen 1909; Peptonococcus Jen- 

 sen 1909; Enterococcusf (Thiercelin) Rougentzoff 1914. 



Parasites. Cells in groups and short chains, very rarely in 

 packets. Generally stain by Gram. On agar streak good 

 growth, of white or orange color. Glucose, maltose, sucrose and 

 often lactose, fermented with formation of moderate amount of 

 acid. Gelatin often liquefied very actively. 



Type species is Staphylococcus aureus Rosenbach. 



Tribe C. Micrococceae Trevisan, 1889b, p. 1067, emended 

 (as Metacoccaceae) Winslow and Rogers 1905, p. 669 



Facultative parasites or saprophytes. Thrive best under 

 aerobic conditions. Grow well on artificial media, producing 

 abundant surface growths. Planes of fission often at right 

 angles; cell aggregates in groups, packets or zoogleal masses. 

 Generally decolorize by Gram. Pigment yellow or red. 



Genus 6. Micrococcus Cohn 1872 a, p. 153, emended Winslow 

 and Rogers, 1905, p. 669

 Ascococcus Cohn, 1875; Pediococcus Balcke 1884; Merista Van Tieghem 

 1884, not Merista (Banks and Soland) Cunningham 1839; Planococcus 

 Migula 1894; Urococcus Miquel 1879; not Urococcus Kuetzing 1849;

 toszewicz and Schwarzwasser 1906; Solidococcus Jensen 1909; Piano- 

 merista Vuillemin 1913. 



Facultative parasites or saprophytes. Cells in plates or ir- 

 regular masses (never in long chains or packets). Generally 

 decolorize by Gram. Growth on agar abundant, with formation
