What are the common symptoms of Campylobacter infection?

Common symptoms of Campylobacter infection primarily include bloody diarrhea and abdominal cramps. Campylobacter is a type of bacteria that can cause gastroenteritis, leading to inflammation of the gastrointestinal tract. When a person is infected, the bacteria often cause the intestine to become inflamed, resulting in diarrhea that may contain blood due to damage to the intestinal lining. Along with diarrhea, abdominal cramps are typically experienced as the body reacts to the infection.

The other symptoms mentioned in the options can occur in various other infections or conditions but are not the hallmark indicators of Campylobacter infection specifically. For instance, while fever and muscle aches can accompany several infections, they are not as distinctive for Campylobacter as bloody diarrhea and cramps are. Symptoms such as severe vomiting or a skin rash and joint pain may be associated with different infectious agents or health conditions, making them less relevant to this specific bacterial infection. Therefore, the defining characteristics of Campylobacter infection center around the gastrointestinal disturbance it creates, particularly the bloody diarrhea and accompanying cramps.
