What Is Campylobacter and How Is It Transmitted?
Campylobacter is a genus of bacteria and one of the most common causes of bacterial gastroenteritis worldwide. The most prevalent species affecting humans is Campylobacter jejuni. Infection typically results from consuming undercooked poultry, unpasteurized milk, or contaminated water. Person-to-person transmission is rare but can occur through poor hygiene practices, especially in childcare or eldercare settings.
Campylobacteriosis is especially prevalent in the summer months and is a leading cause of foodborne illness in the United States.
Symptoms and Complications of Campylobacter Infection
Symptoms usually appear 2 to 5 days after exposure and can include:
- Diarrhea (sometimes bloody)
- Abdominal cramping
- Fever
- Nausea and vomiting
- Malaise and fatigue
While most cases resolve without treatment in about a week, serious complications may arise, such as:
- Guillain-Barré Syndrome (GBS): A rare but severe autoimmune response leading to paralysis
- Reactive arthritis
- Sepsis in immunocompromised individuals
- Prolonged diarrhea or post-infectious irritable bowel syndrome (IBS)
Why Culture Is Not Enough to Diagnose Campylobacter
Traditional stool culture methods are time-consuming and often less sensitive. Campylobacter is fastidious and requires specific microaerophilic conditions to grow in culture. As a result, many cases go undiagnosed or misdiagnosed.
Limitations of culture-based detection:
- Takes 48–72 hours for preliminary results
- Requires skilled lab personnel
- Low sensitivity, especially if samples are delayed or mishandled
- Requires additional supplies such as gas jars and a special incubator
Modern immunoassays provide a faster, more accurate solution for identifying Campylobacter and differentiating it from other causes of infectious diarrhea. Meridian’s Campylobacter tests are designed to streamline workflows and improve diagnostic confidence.
Common Treatment for Campylobacter
Most Campylobacter infections are self-limiting and do not require antibiotics. However, antimicrobial therapy is recommended for:
- Patients with severe or prolonged symptoms
- High-risk populations (infants, elderly, immunocompromised)
- Cases involving bloodstream infection or extraintestinal manifestations
Recommended treatment:
- Antibiotics in high-risk populations
- Fluid and electrolyte replacement to prevent dehydration
