Activity Description

Yersinia enterocolitica, a gram-negative bacillus transmitted through contaminated food, untreated water, household animals, and transfused blood products, causes yersiniosis with presentations ranging from acute diarrhea to mesenteric adenitis, terminal ileitis, and pseudoappendicitis. This course reviews the organism's pathogenesis, including its localization in lymphoid tissue and the role of virulence factors such as pYV, urease, Ail, YadA, and Yops. Postinfectious sequelae, including reactive arthritis and erythema nodosum, are also discussed. This course also addresses the evaluation and management of this pathogen, emphasizing targeted stool testing due to prolonged fecal shedding after symptom resolution, supportive care as the foundation of management, and, in selected patients, the use of antimicrobial therapy and surgical evaluation when appendicitis cannot be confidently excluded. Potential complications involve both gastrointestinal and extraintestinal systems, including sepsis, abscess formation, and myocarditis.

This activity reviews the transmission patterns, virulence mechanisms, diagnostic strategies, and management considerations for yersiniosis. Participants gain insight into conditions that mimic yersiniosis, such as pseudoappendicitis, diagnostic stool and imaging findings, potential complications, and evidence-based decisions regarding antimicrobial therapy, hospitalization, infection-control precautions, and preventive counseling. This activity for healthcare professionals is designed to enhance the learner's competence in identifying Y enterocolitica infections, conducting the recommended evaluation, and implementing an appropriate interprofessional approach to manage this condition, thereby improving patient outcomes.


Target Audience

This activity has been designed to meet the educational needs of physicians, physician associates, nurses, pharmacists, and nurse practitioners.

Learning Objectives

At the conclusion of this activity, the learner will be better able to:

  • Identify clinical features of Yersinia enterocolitica.

  • Apply evidence-based diagnostic strategies to confirm an infection with Yersinia enterocolitica.

  • Differentiate indications for each management approach in patients with clinical features of Yersinia enterocolitica infection.

  • Implement interprofessional team strategies to improve care coordination for patients with Yersinia enterocolitica infection.
