Erysipeloid

Rosenbach's Disease, Pseudoerysipelas, Erysipelothrix Infection

What is Erysipeloid?

Erysipeloid is a bacterial infection caused by Erysipelothrix rhusiopathiae, usually seen on the fingers and hands of meat-handlers, fishermen, or veterinarians. The infection lasts for a few days and may resolve on its own.

How is it diagnosed?

History is usually of an occupation requiring handling of unprocessed meat or fish. Symptoms include a reddish rash and swelling of the skin on the fingers or the back of the hand. The swelling may last for a few days.

Physical exam shows an expanding red rash with a clear center, typically on the fingers, hands, or forearms. Fever is occasionally present.

Tests: The bacterium can be cultured from the infected area.

How is Erysipeloid treated?

Antibiotic therapy for seven to ten days will usually clear the infection. In cases involving resistant strains, treatment with a second antibiotic may be required. Intravenous administration of antibiotic is used when endocarditis or arthritic symptoms are present.
