Understanding Yersiniosis
Yersiniosis is an infection caused by the Yersinia enterocolitica bacterium, usually contracted through contaminated food, especially raw or undercooked pork.
Key Fact: Symptoms of yersiniosis in older children and adults can sometimes be confused with appendicitis because they cause severe lower right abdominal pain.
Common Symptoms
Abdominal Pain
Sharp pain on the right side of the abdomen which may mimic appendicitis.
Bloody Diarrhea
Watery or bloody bowel movements lasting for 1-3 weeks.
Fever
A moderate temperature elevation that accompanies the gastrointestinal symptoms.
Joint Pain
Post-infection reactive arthritis that can last for several months.
Risk Factors
- Eating raw or undercooked pork products (like chitterlings)
- Drinking unpasteurized milk or contaminated water
- Poor hygiene when handling raw meat
Diagnosis & Treatment
Diagnosis
Diagnosis is confirmed by finding the bacteria in a stool sample.
Stool Culture
Blood Culture (for severe cases)
PCR Test
Serology
Common Treatments
-
Oral Rehydration: Replacing lost fluids and electrolytes to manage diarrheal symptoms.
-
Antibiotics: Prescribed only for severe or complicated cases, as most resolve on their own.
-
Safe Food Handling: Preventing infection by thoroughly cooking pork and washing hands after handling raw meat.
