Eubacterium

Eubacterium

Eubacterium (/juːbækˈtɪəriəm/) is a genus of Gram-positive bacteria that are part of the normal human gut flora. They are obligate anaerobes, meaning they can only survive in environments that lack oxygen.

Etymology

The term "Eubacterium" is derived from the Greek words "eu" meaning true, and "bacterium" meaning a small rod. This is in reference to the rod-like shape of the bacteria in this genus.

Characteristics

Eubacterium are non-motile, non-spore-forming, and obligate anaerobes. They are Gram-positive bacteria, meaning they retain the violet stain used in the Gram staining method. They are part of the normal human gut flora and are involved in the fermentation of dietary fiber.

Species

There are over 50 recognized species of Eubacterium, including:

• Eubacterium aerofaciens
• Eubacterium biforme
• Eubacterium eligens
• Eubacterium lentum
• Eubacterium limosum

Clinical Significance

While Eubacterium are generally harmless and beneficial to their human hosts, they can cause infections if they enter sterile sites in the body. They have been implicated in cases of bacteremia, endocarditis, and abscess formation.
