Where are Micrococcus found?
Micrococcus strains commonly are found in a large variety of terrestrial and aquatic ecosystems, including soil, fresh and marine water, sand, and vegetation.

Does Micrococcus cause infection?
The genus Micrococcus is not considered to be pathogenic. However, Micrococcus strains have been reported to cause various types of infections, usually as opportunistic pathogens. Thus, M. luteus strains were associated with septic arthritis, prosthetic valve endocarditis, and recurrent bacteremia.
Is Micrococcus good or bad?
