Micrococcus

 

a genus of spherical (diameter, 1–2 μ), nonmotile, nonsporiferous, gram-positive bacteria that reproduce by division in two or three planes and are found singly or in irregular masses.

On solid nutrient media, micrococci form smooth, round colonies of white, yellow, or red. Certain species (for example, M. pyogenes) cause purulent diseases. Micrococci inhabit soil, fresh and salt waters, and food products. Some species develop in brines and cause the appearance of red spots on pickled fish.

The traditional identification of the micrococci is based on their susceptibility to lysozyme and bacitracin and their resistance to lysostaphin and nitrofurantoin, in contrast to staphylococci, which display the opposite pat tern.
Since early reports of endocarditis caused by gram-positive cocci that appear in tetrads and packets often did not reliably differentiate between micrococci and phenotypically similar microorganisms, such as coagulase-negative staphylococci, the frequency of micrococcal endocarditis is difficult to ascertain and might be underestimated.
