Which factors influence the severity of Campylobacter disease?

• A. Dietary fiber intake
• B. Number of organisms, prior exposure, coexisting disease, stress
• C. Geographic location
• D. Presence of other viruses

Answer: (B)

The level of illness from Campylobacter is mainly determined by how much bacteria you’re exposed to and how your body handles the infection. A larger inoculum gives the gut more bacteria to fight, typically leading to more severe inflammation, diarrhea, and fever. Prior exposure can provide partial immunity, which can lessen the severity by enabling a quicker and more effective immune response. Coexisting diseases, such as immunosuppression, chronic illnesses, or malnutrition, weaken defenses and often intensify symptoms. Stress can also influence immune function and gut physiology, potentially worsening illness. The other options don’t directly determine how severe the disease becomes: dietary fiber affects gut microbiota and stool form but isn’t a direct determinant of Campylobacter illness severity; geographic location changes exposure risk but not the severity once infected; presence of other viruses may complicate illness in some cases but isn’t the primary driver of how severe Campylobacter disease is.
