Peptostreptococcus anaerobius is a species of bacteria belonging to the Peptostreptococcus genus of anaerobic, Gram-positive, non-spore forming bacteria. The cells are small, spherical, and can occur in short chains, in pairs or individually. [2] Peptostreptococcus are slow-growing bacteria sometimes resistance to antimicrobial drugs. [3] P. anaerobius is intrinsically resistant to sodium polyethanol sulfonate (SPS), a component found in many types of blood culture media. [4]
Peptostreptococcus anaerobius is present as part of the microbiota of the lower reproductive tract of women and has been recovered from women with pelvic inflammatory disease and bacterial vaginosis. [5] [6]
It is one of several bacteria in the human microbiome associated with the development of colorectal cancer and cervical cancer. [7] [8] [9]
