Peptococcus

Peptococcus

 [pep″to-kok´us]
a genus of gram-positive, anaerobic, coccoid bacteria; they are part of the flora of the mouth, upper respiratory tract, and large intestine, and also cause soft tissue infection and bacteremias. P. mag´nus is the species most often recovered from clinical specimens.

Peptococcus

(pep'tō-kok'ŭs),
A genus of nonmotile, anaerobic, chemoorganotrophic bacteria (family Peptococcaceae) containing gram-positive, spheric cells that occur singly, in pairs, tetrads, or irregular masses, and rarely in short chains. They are frequently found in association with pathologic conditions. The type species is Peptococcus niger.

(2,5,6,7,8) It has a polymicrobial aetiology that includes Gardnerella vaginalis, Mycoplasma hominis, and various obligate anaerobes like Bacteroides, Prevotella, Porphyromonas, Peptostreptococcus, Peptococcus, Veillonella, Eubacterium, Mobiluncus, (5,6,8,9) Peptoniphilus, and Fusobacterium.
As documented in multiple prior reports, the most common pathogens are the gram-negative anaerobic bacilli, such as Bacteroides and Prevotella species; the anaerobic gram-positive organisms, including Peptococcus and Peptostreptococcus species; aerobic gram-negative bacilli, such as Escherichia coli, Klebsiella pneumoniae, and Proteus species; and aerobic gram-positive cocci, such as group B streptococci, enterococci, and staphylococci.
