Phylum Proteobacteria, Class Epsilonproteobacteria, Order Campylobacterales, Family Campylobacteraceae, Genus Campylobacter,
Campylobacter coli (Doyle 1948) Véron and Chatelain 1973.
Possible synonym: Campylobacter hyoilei Alderton et al. 1995.
Gram-negative, curved, S-shaped or coiled spiral cells, small, 0.2-0.3 x 1.5-5.0 μm.
Changes to coccoid forms in oxygen atmosphere.
Grayish, round, 1-2 mm in diameter, raised, convex, smooth and glistening colonies.
Usually nonhemolytic. Grow on solid media containing 1.0–1.5% ox-bile, 0.02%
safranin, 32 mg/l cephalothin, 0.04% triphenyl-tetrazolium chloride or 1% glycine.
No growth in 2% NaCl. Grow at 37 ºC, on Columbia agar supplemented with 5%
horse blood in an atmosphere of 50% H2, 45% CO2 and 5% O2 . May grow at 42 ºC,
but not at 25 ºC.
Human & animals (pigs) intestinal tract.
Generally are normal intestinal flora in warm-blooded animals. May cause enteritis in pigs and monkeys and abortion in rodents.
Causes diarrhea, septicemia, and occasionally abortion in humans.
C. hyoilei (possible synonym of C. coli) is associated with porcine proliferative enteritis. The strains originally described as C. hyoilei
may represent a variant of C. coli that is highly adapted for the porcine enteric tract and pathogenic abilities.

Positive results for catalase, oxidase, indoxyl acetate hydrolysis, nitrate reduction & selenite reduction.
Negative results for urea hydrolysis, hippurate hydrolysis & H2S production on TSI (with some exceptions).
