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.
