Yersiniosis is a relatively uncommon infection contracted through the consumption of undercooked meat products (especially pork), unpasteurized milk, or contaminated water.
People with high iron levels are at higher risk of infection and severe disease
Most infections are self-limited. Antibiotics should be given for severe cases. Y. enterocolitica isolates are usually susceptible to trimethoprim-sulfamethoxazole, aminoglycosides, third-generation cephalosporins, fluoroquinolones, and tetracyclines; they are typically resistant to first-generation cephalosporins and most penicillins. Antimicrobial therapy has no effect on postinfectious sequelae.
