Bacterial cellular morphologies : ウィキペディア英語版 | Bacterial cellular morphologies
Bacteria are classified by direct examination with the light microscope through its morphology and aggregation. The basic forms are spheres (coccus) and round-ended cylinders (bacillus). But there may be others such as helically twisted cylinders (spirochetes), cylinders curved in one plane (Selenomonads) and unusual morphologies (such as the square Archaea Haloquadratum). They also conform diplos, tetrads, staphylos, streptos, palizadas etc. ==Coccus==
A coccus (plural ''cocci'', from the Latin ''coccinus'' (scarlet) and derived from the Greek ''kokkos'' (berry)) is any microorganism (usually bacteria) whose overall shape is spherical or nearly spherical. Describing a bacterium as a coccus, or sphere, distinguishes it from bacillus, or rod. This is the first of many taxonomic traits for identifying and classifying a bacterium according to binomial nomenclature.
