Mi`cro*coc"cus, n.; pl. Micrococci. Etym: [NL. See Micro-, and
Coccus.] (Biol.)
Definition: A genus of Spherobacteria, in the form of very small globular
or oval cells, forming, by transverse division, filaments, or chains
of cells, or in some cases single organisms shaped like dumb-bells
(Diplococcus), all without the power of motion. See Illust. of
Ascoccus.
Note: Physiologically, micrococci are divided into three groups;
chromogenic, characterized by their power of forming pigment;
zymogenic, including those associated with definite chemical
processes; and pathogenic, those connected with disease.
