What are the symptoms associated with Campylobacter infection?

The chosen response accurately identifies the primary symptoms associated with Campylobacter infection, which is commonly caused by the bacteria Campylobacter jejuni. This infection is primarily characterized by gastrointestinal symptoms. Diarrhea, which may be bloody in some cases, is a hallmark sign of this infection. Alongside diarrhea, a low-grade fever often accompanies the illness, though the fever itself is typically not high. These symptoms arise due to the bacteria affecting the intestines, leading to inflammation and disruption in normal digestive processes.

In contrast, the other choices describe symptoms that do not align with Campylobacter infection. High fever and severe abdominal pain are more indicative of other gastrointestinal disorders, while cough and sore throat are associated with respiratory infections rather than gastrointestinal issues. Lastly, a rash and severe headache are not typical symptoms of Campylobacter; rather, they may relate to different infections or conditions. Thus, recognizing diarrhea (potentially bloody) and low-grade fever emphasizes the specific symptoms tied to Campylobacter infections.
