Phylum Proteobacteria, Class Epsilonproteobacteria, Order Campylobacterales, Family Campylobacteraceae, Genus Campylobacter,
Campylobacter mucosalis (Lawson et al. 1981) Roop et al. 1985.
A, B, and C serovars have been described.
Old synonym: Campylobacter sputorum subsp. mucosalis (ex Lawson and Rowland 1974) Lawson et al. 1981
Gram-negative, short, irregularly curved, 0.25-0.30 x 1-3 μm. Coccoid and 7-8 μm long
forms appear in old cultures. Motile by a single bipolar flagellum.
Colonies are 1.5 mm in diameter, circular, raised with a flat surface, and have a dirty
yellowish color. Swarming may occur.
Does not grow microaerobically on common agar bases in an atmosphere without
hydrogen. Grows anaerobically in an atmosphere containing hydrogen and fumarate.
Grows at 37 ºC, 42 ºC, but not at 25 ºC. Grows in the presence of 1.0% ox-bile and
0.032% methyl orange. Most strains grow in the presence of 0.01% Janus green and
0.005% basic fuchsin. No growth in 0.04% triphenyltetrazolium chloride.
Isolated from the oral cavity and intestinal mucosa of pigs with porcine intestinal adenomatosis, necrotic enteritis, regional ileitis,
and proliferative hemorrhagic enteropathy.
Undetermined. May be associated with Lawsonia intracellularis proliferative enteritis in pigs.

Positive results for H2S production on TSI and oxidase.
Negative results for catalase, nitrate reduction, selenite reduction, indoxyl acetate hydrolysis, hippurate hydrolysis and urea hydrolysis.
No carbohydrates fermentation.
