Coccus

Cocci ( from Ancient Greek κόκκος KOKKOS " core ", " grain " ) are spherical bacteria. You can totally appear round or be easily shaped oblong to ovate. In the scientific name of the bacteria is the notation " coccus ".

To separate the cells not by the division result as a function of the plane of division organization patterns that may be typical for certain species. A distinction

• Kettenkokken or streptococci: a chain-like bearing cocci, such as Streptococcus, Enterococcus, Peptostreptococcus, Ruminococcus, Lactococcus
• Diplococci: pairs stored cocci, such as pneumococcal ( where it is Streptococcus pneumoniae), Neisseria, Planococcus
• Tetrakokken or tetrads: assembly of four cells, such as Micrococcus, Pediococcus
• Paketkokken or sarcinse: cube-shaped assembly of 8 or more cocci, eponymous this is Sarcina, also encountered in Sporosarcina
• Haufenkokken or staphylococci: heap linear supported cocci, joint storage resembles that of berries in a cluster, eponymous for Staphylococcus, but also in Peptococcus is to be found.

However, some bacterial species are also several division pattern, such as in Lactococcus lactis occur in pairs ( diplococci ) and short chains ( streptococci) whose cells.
