Peptostreptococcus spp. can cause infections such as gluteal decubitus ulcers, diabetes-related foot infections, and rectal abscesses. Anaerobic gram-positive cocci and microaerophilic streptococci are part of the normal skin microbiota, so it is hard to avoid contamination by these bacteria when obtaining specimens.
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]
Peptostreptococcus and Bacteroides spp. are the most frequently recovered isolates at all bone infections, including those caused by bites and cranial infection. Pigmented Prevotella and Porphyromonas spp. are especially common in bite and skull bone infections, whereas members of the B. fragilis group are often found in vascular disease or ...
Finegoldia is a genus of Gram-positive bacteria.They are anaerobic cocci of the class Clostridia, with Finegoldia magna being the type species. [1] F. magna was formerly known, along with several other Gram-positive anaerobic cocci (GPACs), as Peptostreptococcus magnus, but was moved into its own genus in 1999.
These six genera (Peptostreptococcus, Peptoniphilus, Parvimonas, Finegoldia, Murdochiella, and Anaerococcus) are found in the human body as part of the commensal human microbiota. [6] [7] [5] It is commonly found in the human microbiome and is associated with various infections. [8]
S. agalactiae, or group B streptococcus, GBS, causes pneumonia and meningitis in newborns and the elderly, with occasional systemic bacteremia. Importantly, Streptococcus agalactiae is the most common cause of meningitis in infants from one month to three months old.

Peptostreptococcus species occupy a specialized niche in the rumen of dairy cows, sheep, and deer as peptide- and amino acid-degrading microorganisms. By producing high levels of ammonia , these bacteria play a crucial role in nitrogen recycling within the rumen ecosystem.
