 Crenothrix polyspora 

 Cladothrix dichotoma 

 Clonothrix fusca 



The Winslows (1908) presented the final results of their studies on 

 the Coccaceae. A key to the subfamilies and genera recognized 

 follows : 



Winslows' Classification of the Coccaceae (1908) 



Cells spherical. Family Coccaceae 

 I. Parasites. Growth not abundant (or one species, zooglea-forming sapro- 

 phytes growth abundant in saccharose media). Generally gram+. Acid 

 formers Subfamily Paracoccaceae 



A. Cells in capsulated pairs. Parasites. Growth very meagre. Inulin 



fermented. No pigment. 



Diplococcus (Weichselbaum) Winslow and Rogers 



B. Cells in chains occuring in masses of zoogloea in sugar refineries. 



Aberrant saprophytic forms. Growth abundant in saccharose 

 media. No pigment Ascococcus (Cohn) Winslow and Rogers 



C. Cells in chains. Parasites. Growth meagre. Inulin not fermented. 



No pigment Streptococcus (Billroth) 



D. Cells in irregular groups Staphylococcus 



1. Parasites. Growth fair. Orange pigment. 



Aurococcus Winslow and Rogers 



2. Parasites. Growth good. White pigment. 



Albococcus Winslow and Rogers- 

 II. Saprophytes. Growth abundant. No zoogloea. Gram— generally. Not 

 acid formers Subfamily Metacoccaceae 



A. Cells in irregular groups. Pigment generally yellow. 



Micrococcus (Hallier, Cohn), Winslow & Rogers 



B. Cells in packets. Pigment yellow. 



Sarcina (Goodsir) Winslow and Rogers 



C. Cells in irregular groups or packets, pigment red. 



Rhodococcus Winslow and Rogers 



Fliigge (1908) in the classification of the pathogenic bacteria given 

 in his Grundriss der Hygiene (sixth edition) made a distinct contri- 

 bution to systematic bacteriology in the groupings which he created. 

 From a strict nomenclatural point of view his terminology was in 

 many cases technically incorrect, but the groups are very useful. 

 His classification is as follows :
