Campylobacter rectus
Species of bacterium
From Wikipedia, the free encyclopedia
Campylobacter rectus is a species of Campylobacter. It is implicated as a pathogen in chronic periodontitis, which can induce bone loss. This motile bacillus is a Gram negative, facultative anaerobe. C. rectus is associated with hypertension together with Prevotella melaninogenica and Veillonella parvula.[1]

It was first described and characterized as Wolinella recta in 1981 after the bacterium was isolated from human patients with gingivitis, periodontitis, and periodontosis.[2] The species name was changed to Campylobacter rectus in 1991 after phylogenetic analyses grouped it closely with other members of rRNA Group I Campylobacter.[3]
Physiology
C. rectus is gram negative, rod-shaped, and anaerobic, although growth in 5% oxygen is possible for some strains.[2] It can use hydrogen and formate for energy, but does not metabolize carbohydrates, and can reduce nitrite.[2] C. rectus is susceptible to multiple classes of antibiotics.[2]
The bacterium is surrounded by a surface-layer, or S-layer, which forms a protective lattice on the surface of the bacterium. The S-layer may be implicated in virulence and in host-bacteria interactions.[4][5] C. rectus moves using a single flagellum on one pole, and some strains can form biofilms without the loss of motiliy.[2][5]
