''Campylobacter'' [[Species|spp]]. generally appear as curved or comma-shaped [[Rod-shaped bacterium|rods]], and are able to move via unipolar or bipolar [[Flagellum#Bacterial|flagella]].<ref name="Bergey's" /> They grow best between 37–42&nbsp;°C in a [[Microaerophile|microaerophilic]] environment.<ref>{{Cite web |date=2019-12-23 |title=Information for Health Professionals {{!}} Campylobacter |url=https://www.cdc.gov/campylobacter/technical.html |access-date=2020-11-02 |website=Centers for Disease Control and Prevention |language=en-us}}</ref> When exposed to atmospheric oxygen, ''C. jejuni'' is able to change into a [[coccus]] form.<ref name="Crushell04">{{Cite journal |last=Crushell |first=Ellen |last2=Harty |first2=Sinead |last3=Sharif |first3=Farhana |last4=Bourke |first4=Billy |date=January 2004 |title=Enteric Campylobacter: Purging Its Secrets? |url=https://www.nature.com/articles/pr20042 |journal=Pediatric Research |language=en |volume=55 |issue=1 |pages=3–12 |doi=10.1203/01.PDR.0000099794.06260.71 |issn=1530-0447 |pmid=14605259|doi-access=free }}</ref> Most species of ''Campylobacter'' are positive by the [[oxidase test]] and [[catalase test]] and are able to [[Nitrate reductase test|reduce nitrate]]. The number of known [[Quinolone antibiotic|quinolone]]-resistant ''Campylobacter'' strains is growing. It is suggested that this is caused by the overuse of quinolone antibiotics in animal agriculture.<ref name="Crushell04" />
