Campylobacteriosis: Symptoms, Treatment, and Prevention
Definition
Campylobacteriosis is an infection caused by Campylobacter bacteria, which is a common cause of foodborne illness. The infection typically affects the gastrointestinal tract, leading to symptoms like diarrhea, fever, and abdominal cramps.
Types
There are several species of Campylobacter bacteria, but the most common ones causing human illness include:
- Campylobacter jejuni: The most prevalent species associated with human infections.
- Campylobacter coli: Less common but also a cause of human illness.
Causes & Risk Factors
Campylobacteriosis is primarily caused by ingesting Campylobacter bacteria, which can occur through:
- Consumption of undercooked poultry.
- Drinking untreated water.
- Eating contaminated food products.
- Contact with infected animals, particularly poultry.
Risk factors include:
- Poor food handling practices.
- Travel to areas with poor sanitation.
- Consuming raw or undercooked meat.
- Exposure to contaminated water sources.
Pathophysiology
After ingestion, Campylobacter bacteria colonize the intestines and produce toxins that cause inflammation and damage to the intestinal lining. This results in symptoms such as diarrhea and abdominal pain. The body's immune response to the infection can also contribute to symptoms and complications.
Symptoms
Symptoms of campylobacteriosis typically appear 2-5 days after exposure and can include:
- Diarrhea, which may be bloody
- Severe abdominal cramps
- Fever
- Nausea and vomiting
- Malaise
Diagnosis
Diagnosis of campylobacteriosis involves clinical evaluation and laboratory tests, including:
- Stool culture to identify Campylobacter bacteria.
- Polymerase Chain Reaction (PCR) tests to detect Campylobacter DNA.
- Blood tests in severe cases to check for complications.
Management & Treatment
Treatment of campylobacteriosis focuses on relieving symptoms and preventing dehydration. Key treatment methods include:
- Hydration therapy, including oral rehydration solutions.
- Rest and maintaining fluid intake.
- Antibiotics such as azithromycin or ciprofloxacin for severe cases or at-risk populations.
- Antidiarrheal medications are generally avoided as they can prolong the infection.
Transmission
Campylobacteriosis is primarily transmitted through the ingestion of contaminated food or water. It can also spread through direct contact with infected animals or their environments, or through contact with contaminated surfaces.
Complications
While most people recover without complications, severe cases of campylobacteriosis can lead to:
- Severe dehydration
- Guillain-Barré Syndrome (GBS), a rare autoimmune disorder
- Reactive arthritis
- Sepsis in immunocompromised individuals
Prevention
Preventing campylobacteriosis involves good hygiene and food safety practices, such as:
- Cooking poultry and meat thoroughly.
- Avoiding raw milk and unpasteurized dairy products.
- Washing hands, kitchen surfaces, and utensils with soap and water after handling raw foods.
- Drinking only treated or boiled water.
- Practicing good hand hygiene, especially after contact with animals.
FAQs

The first signs of campylobacteriosis usually include diarrhea, abdominal cramps, and fever.
How is campylobacteriosis diagnosed?
Campylobacteriosis is diagnosed through stool cultures, PCR tests, and blood tests to identify the presence of Campylobacter bacteria and potential complications.
Can campylobacteriosis be prevented?
Yes, campylobacteriosis can be prevented through proper food handling, cooking, and hygiene practices, as well as avoiding contaminated food and water.
Is there a vaccine for campylobacteriosis?
