Mycoplasma /My·co·plas·ma/ (mi´ko-plaz″mah) a genus of pleomorphic, gram-negative, aerobic to facultatively anerobic bacteria lacking cell walls, including the pleuropneumonia-like organisms; species include M. ho´minis, which is associated with nongonococcal urethritis and mild pharyngitis, and M. pneumo´niae, a cause of primary atypical pneumonia.

| Mycoplasma n. A genus of nonmotile parasitic pathogenic microorganisms whose members lack a true cell wall, are gram-negative, and require sterols such as cholesterol for growth. |

Mycoplasma
A type of free-living microorganism that has no cell wall. Mycoplasmas cause some varieties of pneumonia and urinary tract infections that stimulate the body to produce cold agglutinins.

Mycoplasma
[mī′kōplaz′mə]
Etymology: Gk, mykes + plassein, to mold
a genus of ultramicroscopic organisms lacking rigid cell walls and considered to be the smallest free-living organisms. Some are saprophytes, some are parasites, and many are pathogens. One species is a cause of mycoplasma pneumonia, tracheobronchitis, pharyngitis, and bullous myringitis. See also pleuropneumonia-like organism.

a hemophilic species found in rats that is transmitted by lice and is usually apathogenic, but can cause fatal anemia in splenectomized or immunosuppressed animals.
Mycoplasma ovis
a hemophilic species that can cause anemia and ill thrift in weaner sheep, although infection is often inapparent. Previously called Eperythrozoon ovis.
Mycoplasma suis
a hemophilic species that causes anemia and jaundice in piglets. Can cause high mortalities. Previously called Eperythrozoon suis.
