What is a notable clinical feature of Campylobacter jejuni infection?

A notable clinical feature of Campylobacter jejuni infection is reactive arthritis. This type of arthritis can develop following an episode of gastrointestinal infection caused by the bacterium, particularly when it is related to a triggering immune response. Campylobacter jejuni is one of the most common bacterial causes of gastroenteritis worldwide, and in some cases, it can result in a post-infectious complication known as reactive arthritis, which is characterized by joint pain and swelling typically beginning after an initial bowel infection.

While sepsis, meningitis, and pneumonia are serious medical conditions, they are not particularly characteristic of Campylobacter jejuni infections. Sepsis may occur as a complication from various infections, but it is less commonly associated with Campylobacter, which primarily affects the gastrointestinal tract. Meningitis, an inflammation of the protective membranes covering the brain and spinal cord, and pneumonia, an infection of the lungs, are not typical complications of Campylobacter jejuni infection. Thus, reactive arthritis stands out as a noteworthy sequela linked specifically to the infection.
