Anaerobiospirillum succiniciproducens
Species of bacterium
From Wikipedia, the free encyclopedia
Anaerobiospirillum succiniciproducens is a species of spiral-shaped, Gram-negative, obligately anaerobic bacteria in the genus Anaerobiospirillum, first described in 1976.[1] It is primarily found in the gastrointestinal tracts of humans and animals, such as dogs and cats, and has also been implicated in rare but significant clinical infections.

The species name succiniciproducens refers to the bacterium's ability to produce succinic acid as a major fermentation product.
Morphology and physiology
Anaerobiospirillum succiniciproducens cells are helical to spiral-shaped rods approximately 0.7 μm in diameter and 2–6 μm long. They are motile by means of bipolar tufts of flagella and do not form spores. Colonies are smooth, translucent, and non-hemolytic when cultured anaerobically on enriched media.
Biochemically, the species produces succinic acid as the major end-product of fermentation, along with acetic acid.
Ecology
The bacterium is commonly found in the normal gastrointestinal microbiome of dogs and cats and has been isolated from human feces.
Clinical relevance
Although not commonly pathogenic, A. succiniciproducens has been associated with human infections, including bacteremia, diarrhea, pyomyositis, and soft tissue infections. These cases often occur in immunocompromised individuals or those with underlying conditions.[2][3]
Type strain
The type strain of Anaerobiospirillum succiniciproducens is VPI C3-3 (= ATCC 29305).
