How can Eubacteria be classified?
Eubacteria can also be classified according to shape, configuration, respiration and nutrition. Most organisms are either spherical, rod, or spiral in shape. After division, bacteria group together and form either cocci, bacilli, spirillia, pairs, clumps or chain configurations. Large numbers of cells are referred to as colonies. Some bacteria require oxygen so they are aerobic (ex: bacteria causing tuberculosis) whereas those that don’t are called anaerobic (ex: bacteria causing tetanus).
