Bloody stools occur in about what percentage on which days in Campylobacter infection?

• A. About 50% on the first day
• B. About 5% on the fourth day
• C. About 30% on the third day
• D. About 15% on the 2nd or 3rd day

Answer: (D)

In Campylobacter infection, bleeding is not the most common feature, but it can occur as the illness progresses. The typically observed pattern is that a minority of patients develop bloody stools, usually around the second to third day of illness, when the inflammatory process in the colon has progressed. About 15% of cases show this bleeding by that time, making the second or third day the most consistent window for bloody stools. So the statement that best fits clinical observations is approximately 15% on the 2nd or 3rd day.
