The features of fever, abdominal cramping, watery stools, and fluid and electrolyte loss, which can progress to bloody stools, are indeed characteristic of shigellosis. This type of gastrointestinal infection can also be associated with an infection caused by Campylobacter spp.

Campylobacter infections are primarily caused by Campylobacter jejuni and are often linked to the consumption of undercooked poultry or contaminated water. The infection typically begins with symptoms such as diarrhea, which may start off watery and can eventually become bloody. Other gastrointestinal symptoms, such as abdominal pain and fever, are also common in Campylobacter infections.

This aligns closely with the presentation of shigellosis, making it a relevant option. Campylobacter is known to cause similar gastrointestinal disturbances, including the potential for bloody diarrhea due to inflammation and ulceration of the intestinal mucosa.

The other options may cause gastrointestinal disease, but their presentations differ more significantly from those typically seen in shigellosis or are less known for causing similar bloody diarrhea following initial watery stools.
