  • In humans infections most commonly present in a mild cutaneous form known as erysipeloid or fish poisoning.
  • Erysipeloid, localized cellulitis, infections are most commonly diagnosed on the extremities, including the fingers and hands, where contact with contaminated material and damaged skin is most likely to occur.
  • Infections in humans are usually due to occupational exposure observed among butchers, veterinarians, meat porters, cooks, farmers and marine workers.
  • Portal of entry is usually through abrasions or puncture wounds of the skin.
  • Healing usually takes 3-4 weeks, but can take months and relapses are common.
  • Appropriate antibiotic therapy shortens the clinical illness and reduces the risk of relapse.
