Peptostreptococcus

 [pep″to-strep″to-kok´us]
a genus of gram-positive, aerobic, coccoid bacteria; they are part of the normal flora of the mouth, upper respiratory tract, and large intestine and are also opportunistic pathogens that cause soft tissue infections and bacteremias. Species include P. anaero´bius, P. lanceola´tus, P. mi´cros, and P. produc´tus.

Peptostreptococcus

(pep'tō-strep'tō-kok'ŭs),
A genus of nonmotile, anaerobic, chemoorganotrophic bacteria (family Peptococcaceae) containing spheric to ovoid, gram-positive cells that occur in pairs and short or long chains. These organisms are found in normal and pathologic female genital tracts and blood in puerperal fever, in respiratory and intestinal tracts of normal humans and other animals, in the oral cavity, and in pyogenic infections, putrefactive war wounds, and appendicitis; they may be pathogenic. The type species is Peptostreptococcus anaerobius.

Peptostreptococcus

[pep′təstrep′təkok′əs]
a genus of gram-positive anaerobic chemoorganotrophic bacteria that occur in pairs or chains. The potentially pathogenic organisms are found in normal and pathological female genital tracts and in the intestinal and respiratory tracts of normal humans. They have been associated with a variety of disorders ranging from appendicitis to putrefactive wounds.
