Micrococcus roseus is a Gram-positive bacterial cell that finds its main home living on mammalian skin. It gets its first name from the coccus cell shape, which is a sphere or oval. The last name roseus comes from its pink color, according to Schenectady County Community College.
Aside from human skin, it also likes to live on meat and dairy products, or in soil and water. It is not a serious pathogen for humans. If an individual is immune compromised, though, it can become opportunistic, reports Schenectady County Community College. This organism is frequently found in the lab for academic study and use.
