etc."Peptostreptococcus" is a
genus of anaerobic,Gram-positive , non-spore forming bacteria. The cells are small, spherical, and can occur in short chains, in pairs or individually.cite book | author = Ryan KJ; Ray CG (editors) | title = Sherris Medical Microbiology | edition = 4th ed. | publisher = McGraw Hill | year = 2004 | id = ISBN 0-8385-8529-9 ] "Peptostreptococcus" are slow-growing bacteria with increasing resistance toantimicrobial drugs.cite journal | author = Higaki S, Kitagawa T, Kagoura M, Morohashi M, Yamagishi T | title = Characterization of Peptostreptococcus species in skin infections | journal = J Int Med Res | volume = 28 | issue = 3 | pages = 143–7 | year = 2000 | pmid = 10983864]Pathogenesis
"Peptostreptococcus" species are
commensal organisms in humans, living predominantly in the mouth, skin, gastrointestinal, andurinary tract s, and compose a portion of the bacterialgut flora . Underimmunosuppressed or traumatic conditions these organisms can becomepathogen ic, as well as septicemic, harming their host. "Peptostreptococcus" can cause brain, liver, breast, and lungabscess es, as well as generalized necrotizing soft tissueinfection s.cite book | author = Mader JT, Calhoun J | title = Bone, Joint, and Necrotizing Soft Tissue Infections.
