Genus
Micrococcus
Type Strain: ATCC 4698 = CCUG 5858 = NCTC 2665
Macromorphology (smell): Forms yellowish colonies with granular surface.
Micromorphology: Small cocci (0.5 to 3.5 µm in diameter), which are usually arranged in tetrads or irregular clusters.

Metabolism: Aerobic
Catalase/Oxidase:+/+
Other Enzymes: Coagulase -
Spec. Char.:
Reservoir: Soil, dust, water and air.
Disease:May cause infections in immunocompromised individuals. May also cause food poisoning due to production of cadaverin, which potentiates the effect of histamine.
Hosts: Belongs to the normal bacterial flora on the skin of mammalians.

One of the operons seems to be split in one of the 16S rRNA genes.

Taxonomy/phylogeny:
 
The genus Micrococcus is composed of only one species, which is related to the genera Renibacterium and Dermatophilus.
Comment:There are three different biovars: I, II and III.

New families introduced within the order Enterobacterales
Phylogenetic tree for the order <i>Enterobacteriales</i>.

The order Enterobacterales (formerly called Enterobacteriales) previously consisted of bacteria with different properties and phylogenetically, these bacteria were far apart. In order for the taxonomy to be more in line with phylogeny, some of these bacteria have, therefore, been sorted into 6 new families.
