Coccus

Staphylococcus bacteria

Coccus (plural cocci) is a term used to describe any bacterium that has a spherical, ovoid, or generally round shape.[1] It is one of the three distinct bacterial shapes, the other two being bacillus (rod-shaped) and spiral-shaped cells.

Coccus is an English loanword of a Neolatin noun, which in turn stems from the Greek masculine noun kokkos (κόκκος) meaning "berry".[2]

Arrangements

Cocci may occur as single cells or remain attached following cell division. Those that remain attached can be classified based on cellular arrangement:[1]
