Streptobacillus moniliformis
Streptobacillus moniliformis is a non-motile, Gram-negative rod-shaped bacterium that is a member of the family Leptotrichiaceae. The genome of S. moniliformis is one of two completed sequences of the order Fusobacteriales. Its name comes the Greek word streptos for "curved" or "twisted", and the Latin words bacillus meaning "small rod" and moniliformis for "necklace". S. moniliformis is microaerophilic, requiring less oxygen than is present in the atmosphere for its growth.
