|Etymology:||Genus name: a curved rod. |
Species epithet: from a hog's intestine.
Subspecies epithet: in honor of the Brittish bacteriologist Gordon H.K. Lawson.
|Significance:||[Of minor importance]|
|Type Strain:||CHY 5 = CCUG 34538 = NCTC 12901.|
|Macromorphology (smell):||Small circular and convex colonies (1.5-2.0 mm in diameter) after 48 h. Many strains give hemolysis on blld agar.|
|Micromorphology:||Loosely spiraled and bent rods (0.2 x 1.42 µm.|
|Gram +/Gram -:||G -|
|Other Enzymes:||Hippuricase - (hippurat -), urease -|
|Biochemical Tests:||Hydrogen sulfide (H2S) (+)|
|Fermentation of carbohydrates:||Campylobacter spp. can neither ferment nor oxidize carbohydrates.|
|Disease:||The bacterium has been isolated from the stomach of pigs, but pathogenicity has not been shown.
|16S rRNA Seq.:|
||About 40 species have been described within in the genus Campylobacter and some of these are further divided into subspecies. This genus is closely related to the following genera: Sulfurospirillum, Arcobacter and Helicobacter. C. hyointestinalis is closely related to C. fetus and C. coli.|
