    • n Micrococcus (Biol) 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.☞ 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.

    • n micrococcus A genus of Schizomycetes (fission-fungi or bacteria), and the only one of the tribe Sphærobacteria. It is characterized by globular or oval slightly colored cells, either formed by transverse division into filaments of two or several chaplet-like articulations, or united in families, or segregated in gelatinous masses, all destitute of spontaneous movement but exhibiting a simple molecular tremor. Its species are divided into three physiological groups—chromogenes, producing coloring matter, as in “red milk” (M. prodigiosus, figured under microbe), or “golden yellow” (M. luteus); zymogenes, producing various fermentations, as in animal and vegetable infusions (M. crepusculum) or urine (M. ureæ); and pathogenes, producing diseases. Variola, vaccinia, septicemia, erysipelas, gonorrhea, and other forms are believed to be produced by micrococci.
    • n micrococcus [lowercase) pl. micrococci (-sī).] Any member of this genus.
