Anaerobiospirillum is a genus of Gram-negative, spiral-shaped, obligately anaerobic bacteria in the family Succinivibrionaceae. The genus was first described in 1976 based on the type species Anaerobiospirillum succiniciproducens which was isolated from from the gastrointestinal tract of humans. [1] A second species, Anaerobiospirillum thomasii , was later described in 1997 based on isolates from the feces of domestic animals and humans with diarrhea. [2]
Anaerobiospirillum species have been isolated from the intestinal tracts of various animals, including cats, dogs, and pigs. Occasional human isolates suggest either zoonotic transmission or commensal presence in the human gut under certain conditions.
Although generally considered rare pathogens, members of the genus have been associated with human infections, including bacteremia, diarrhea, pyomyositis, and soft tissue infections. Infections are more frequently reported in immunocompromised individuals. [3] [4]
The genus includes two validly published species:
