Anaerobiospirillum

Anaerobiospirillum is a genus of bacteria that is part of the Spirillaceae family. This genus is characterized by its anaerobic nature, meaning it thrives in environments that lack oxygen. The bacteria are rod-shaped and have a unique spiral structure, which is a defining characteristic of the Spirillaceae family.

Characteristics

Anaerobiospirillum bacteria are Gram-negative, meaning they do not retain the violet Gram stain used in Gram staining, a method of differentiating bacterial species. These bacteria are also motile, possessing the ability to move independently using flagella.

Species

There are two recognized species within the Anaerobiospirillum genus: Anaerobiospirillum succiniciproducens and Anaerobiospirillum thomasii. Both species are known to be pathogenic in humans and animals, causing a variety of gastrointestinal diseases.

Anaerobiospirillum succiniciproducens

Anaerobiospirillum succiniciproducens is the most commonly identified species in human infections. It is known to cause bacteremia and septicemia, serious infections that can lead to sepsis if not treated promptly.

Anaerobiospirillum thomasii

Anaerobiospirillum thomasii is less commonly associated with human disease, but it has been identified in cases of diarrhea in dogs.

Pathogenesis

Anaerobiospirillum infections are typically associated with gastrointestinal disease. The bacteria can cause a range of symptoms, including diarrhea, abdominal pain, and fever. In severe cases, the bacteria can enter the bloodstream, leading to bacteremia or septicemia.

Treatment

Treatment for Anaerobiospirillum infections typically involves antibiotics. The bacteria are generally sensitive to a range of antibiotics, including penicillin, ampicillin, and cephalosporins.
