Peptostreptococcus species that are found in clinical infections were once part of the genus formerly known as Peptococcus. Peptostreptococcus is the only genus among anaerobic gram-positive cocci that is encountered in clinical infections. As such, Peptostreptococcus species are viewed
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 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.
Until recently, the genus Anaerococcus have 14 known species. [14] [9] Six of the species were initially classified in the genus Peptostreptococcus but then based on their characteristics were re-classified in the new genus Anaerococcus: A. hydrogenalis, A. lactolyticus, A. octavius, A. prevotii, A. tetradius, and A. vaginalis.
Species in the genus are part of the human microbiome, especially in the bacteria that form the gut flora. They are part of the flora of the mouth, upper respiratory tract and large intestine. Mezlocillin is an antibiotic that is effective against Peptococcus species. Peptococcus niger is the only species left in the

Gemella morbillorum is a species of bacteria within the genus Gemella. It is a facultative anaerobic [1] Gram positive coccus usually preferring capnophilic or microaerophilic environments. [2] From its discovery in 1917 (by R. Tunnicliff) until 1988, it was known as Streptococcus morbillorum (and briefly as Peptostreptococcus morbillorum [3]).
