Answer

Campylobacter organisms are curved or spiral, motile, non–spore-forming, gram-negative rods. Organisms from young cultures have a vibriolike appearance, but, after 48 hours of incubation, organisms appear coccoid. Campylobacter organisms are motile by means of unipolar or bipolar flagellae. They are both oxidase- and catalase-positive and microaerophilic, requiring reduced oxygen (5-10%) and increased carbon dioxide (3-10%). The organisms grow slowly, with 3-4 days required for primary isolation from stool samples, and even longer from blood.
