CLASSIFICATION OF THE BACTERIA 



I. ORDER: EUBACTERIA (True Bacteria) 



A. Sub-order: Haplobacteria (Lower Bacteria) 



I. Family Coccace^. Cells globular, becoming slightly elongate before 

 division. Division in one, two, or three directions of space. Forma- 

 tion of endospores very rare. 



(A) Without flagella. 



1. Streptococcus. Division in one direction of space, producing 



chains like strings of beads. 



2. Micrococcus. Division in two directions of space, so that tetrads 



are often formed. 



3. Sarcina. Division in three directions of space, leading to the 



formation of bale-like packages. 



(B) With flagella. 



1. Planococcus. Division in two directions of space, like micrococcus. 



2. Planosarcina. Division in three directions, like sarcina. 



II. Family Bacteriace^. Cells more or less elongate, cylindric, and 

 straight. They never form spiral windings. Division in one direction 

 of space only, transverse to the long axis of the cell. 



(A) Without flagella. 



1. Bacterium. Occasional endospores. 



(B) With flagella. 



2. Bacillus. Flagella arising from any part of the surface. Endo- 



spore-formation common. 



3. Pseudomonas. Flagella attached only at the ends of the cell. 



Endospores very rare. 

 III. Family SpirillacejE. Cells twisted spirally like a corkscrew, or 

 representing sections of the spiral. Division only transverse to the 

 long diameter.
