General Information:
Campylobacter showae is a common member of the human oral microbiome.
Grows best o­n media containing formate and fumarate.  Will grow anaerobically in 80% N2, 10% CO2, 10% H2, or in a jar under microaerophilic conditions provided by a hydrogen and carbon dioxide generator such as GasPack.
Phenotypic Characteristics:
Gram-negative, motile, straight rods.  Cells are 0.5 to 0.8 um wide and 2 to 5 um long with round ends and two to five unipolar flagella.  The flagella are unsheathed.  In general, C. showae strains are catalase positive while C. rectus strains are catalase negative. The G + C content of the DNA is 44-46%. 
Prevalence and Source:

We find that C. showae is more common in our periodontal clone libraries than C. rectus.  Prior to the recognition that the species C. showae is  distinct from C. rectus in 1993 [1],  isolates of either species would have been called C. rectus.  

Disease Associations:

Campylobacter showae is part of Socransky's Orange Complex of organisms which are associated with periodontal disease [2].
