Knowra Campylobacter jejuni Campylobacter jejuni Campylobacter jejuni is a spiral-shaped, motile bacterium that commonly causes foodborne gastroenteritis. It is microaerophilic, growing best in environments with less oxygen than air.
Campylobacter flagellum : A polar, rotating appendage that propels Campylobacter through liquid and viscous environments. Its flagella help C. jejuni move through intestinal mucus and reach the gut lining.
Campylobacteriosis : An infectious disease caused by bacteria of the genus Campylobacter, usually producing diarrhea and abdominal pain. C. jejuni is the leading cause of human campylobacteriosis.
Guillain–Barré syndrome : An acute immune-mediated disorder in which peripheral nerves are damaged, causing weakness and sometimes paralysis. Molecular mimicry after C. jejuni infection is a major trigger of Guillain–Barré syndrome.
Campylobacter coli : A Campylobacter species that causes human gastroenteritis and is frequently associated with pigs and poultry. It resembles C. jejuni clinically but differs in reservoirs and relative frequency.
Campylobacter : A genus of curved or spiral-shaped bacteria that includes species associated with animal hosts and human disease. C. jejuni is one species within this diverse genus.
Chemotaxis : Directed movement by an organism in response to chemical gradients. C. jejuni uses chemical cues to guide movement toward favorable intestinal niches.
Poultry farming : The raising of domesticated birds, especially chickens and turkeys, for food and other products. Poultry commonly carries C. jejuni without symptoms and is a major source of human infection.
Reactive arthritis : Joint inflammation that develops after an infection elsewhere in the body, without bacteria infecting the joints. C. jejuni gastroenteritis can precede this post-infectious joint condition.
Salmonella enterica : A bacterial species containing serovars that cause intestinal illness and systemic infections in humans and animals. Both are foodborne pathogens, but their physiology, reservoirs, and clinical patterns differ.
Campylobacterales : An order of bacteria that includes the families Campylobacteraceae and Helicobacteraceae. This order places C. jejuni among related spiral-shaped, often host-associated bacteria.
