Species/Subspecies: Campylobacter hyointestinalis subsp. hyointestinalis
Categories: Causes hemolysis; motile
Etymology: Genus name: a curved rod.
Species epithet: from a hog's intestine.

Subspecies epithet: see Species epithet.
Significance:  [Of minor importance]   
Taxonomy:
Phylum
Proteobacteria
Class
Epsilonproteobacteria
Order
Campylobacterales
Family
Campylobacteraceae 
Genus
Campylobacter
Type Strain: 80-4577-4 = ATCC 35217= CCUG 14169 = NCTC 11608.
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 (0.2-0.5 x 1.2-2.5 µm) with darting motility by means of a polar flagellum.
Gram +/Gram -:G -
Metabolism: Microaerophilic
Catalase/Oxidase:
Other Enzymes: Hippuricase - (hippurat -), urease -
Biochemical Tests: Hydrogen sulfide (H2S) (+)
Fermentation of carbohydrates: Campylobacter spp. can neither ferment nor oxidize carbohydrates.
Spec. Char.:
Reservoir: Cattle, pigs, hamster, deer and humans.
Disease:The bacterium has been isolated from the intestine of animals and from feces of humans. Some researchers consider it to be associated with porcine proliferative enteritis and dirrhea in animals and humans. However, pathogenicity has not been proved.
Hosts: Pigs? and humans?
Clinical Picture:

Acc-noStrainNumber of NTOperon
AF097689 NCTC 11608T 1423  

Taxonomy/phylogeny:
 
About 25 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.
