Meet Peptostreptococcus anaerobius: The Stealthy Anaerobic Pathogen

Description

Peptostreptococcus anaerobius is a Gram-positive, anaerobic bacterium that thrives in environments with limited oxygen. It‘s commonly found in the oral cavity, gastrointestinal tract, and female genital tract of healthy individuals. However, under certain conditions, it can transition from a harmless commensal to an opportunistic pathogen.

Associated Diseases

• Despite its seemingly innocuous nature, P. anaerobius plays a significant role in various infections, including:
  • Intra-abdominal infections (e.g., appendicitis, peritonitis)
  • Pelvic inflammatory disease and endometritis
  • Dental infections (e.g., periodontitis, abscesses)
  • Sepsis

Did you Know ?

• P. anaerobius is the third most common anaerobic bacterium isolated from intra-abdominal infections, accounting for approximately 20% of cases.
