Yersiniosis is caused by the enteropathogenic Gram-negative organisms Yersinia enterocolitica and Yersinia pseudotuberculosis, which are worldwide zoonotic pathogens. Disease is acquired by consumption of contaminated food or water and is commonest in childhood, and in colder climates. Presentation is with diarrhoea, fever and abdominal pain, which may mimic appendicitis. Late complications include reactive arthritis, erythema nodosum, and erythema multiforme. Systemic infection is more likely with Y. pseudotuberculosis and a subgroup of Y. enterocolitica, and also in patients with diabetes or iron overload. Diagnosis is by culture of the organism or convalescent serology. Most cases of enteritis are self limiting and antimicrobials are not indicated, but septicaemia or focal infection outside the gastrointestinal tract requires antibiotics (usually cefotaxime, ceftriaxone, or ciprofloxacin). Prevention is by standard food hygiene precautions.
