Phylum Proteobacteria, Class Epsilonproteobacteria, Order Campylobacterales, Family Campylobacteraceae, Genus Campylobacter,
Campylobacter curvus (Tanner et al. 1984) Vandamme et al. 1991.
Basonym: Wolinella curva Tanner et al. 1984.
Gram-negative cells, small and curved, 0.5-1 x 2-6 μm, with rounded or tapered ends.
Helical or straight cells also occur. Motile by means of a single polar flagellum or
bipolar flagella. Presents a membrane-like polar cap at the extremities. Endospores
are not produced.
Colonies vary from small pinpoint, 1 mm in diameter to spreading colonies up to 5 mm
in diameter. Agar pitting is medium dependent; negative in anaerobic, 3-days-old
cultures on 5% blood agar.
Does not grow microaerobically on common agar bases in an atmosphere without
hydrogen. Does not grow in semisolid medium (0.16% agar), in air, or in an
atmosphere containing O2:CO2:N2 (5:10:85). Growth is stimulated in broth cultures by
formate and fumarate.
Strains grow in the presence of 0.005% basic fuchsin and 0.04% triphenyl-tetrazolium
chloride. Most strains (80%) will grow on media containing 64 mg/l cefoperazone, 0.1%
potassium permanganate, 0.01% Janus green and not in 2% NaCl or 2% ox bile.
Isolated from lesions in human oral cavities, from a blood culture, peritoneal fluid and from normal and diarrheic feces of humans.

Positive results for oxidase, indoxyl acetate hydrolysis & nitrate reduction (most strains).
Negative results for catalase, urea hydrolysis, hippurate hydrolysis (most strains), selenite reduction & H2S production on TSI. No
