Which of the following is NOT a symptom of Campylobacter jejuni infection?

Fatigue is not typically recognized as a direct symptom of Campylobacter jejuni infection, which primarily presents with gastrointestinal symptoms. Campylobacter jejuni is a leading cause of bacterial foodborne illness, and its most common symptoms include diarrhea, fever, and abdominal cramps. Diarrhea, often bloody, occurs as the bacteria invade the intestinal lining. Fever may accompany the infection as the body responds to the bacteria, and abdominal cramps result from the inflammation in the gastrointestinal tract.

While fatigue can occur due to dehydration or overall malaise associated with illness, it is not a core or defining symptom of Campylobacter jejuni infection itself. The primary focus of diagnosis and symptoms for this infection tends to revolve around gastrointestinal distress rather than systemic fatigue as a standalone symptom.
