Description and Significance

Describe the appearance, habitat, etc. of the organism, and why you think it is important.

Peptostreptococcus anaerobius is a slow growing, Gram-positive anaerobic cocci (GPAC) bacteria. This means that it is not able to grow in oxygen-rich environments. Peptostreptococcus anaerobius, under the correct harsh conditions, becomes an opportunistic pathogen that can cause multiple deep organ abscesses as well as soft tissue infections (cmr asm). Peptostreptococcus anaerobius is a cocci which means it is a spherical bacterium with a size of 0.3µ to 2.0µ. It can be in pairs, short chains, tetras, small clusters, or irregular masses (ASMscience).

Peptostreptococcus anaerobius is part of the normal microbial flora within the human mouth, upper respiratory, gastrointestinal tract, skin, and female genitourinary system (asmscience). Peptostreptococcus anaerobius is one of the most frequent
