Infectious Disease Compendium

Erysipelothrix rhusiopathiae

Microbiology

Thin gram positive rod.

Epidemiologic Risks

Causes disease in swine (insert your own cheap shot here; Congress being the easiest) and persists for long periods of time in fish, crabs, whales and other animals.

It causes "whale finger." In people, whales I suppose, get flipper disease.

Trauma from the aforementioned animals leads to disease.

Syndromes

A) erysipeloid, a localized skin lesion that acts like an indolent cellulitis. It can spread distally, not proximally.

B) a diffuse skin eruption with systemic symptoms, and

C) bacteremia with or without endocarditis.

Treatment

Penicillin OR imipenem OR ciprofloxacin.

Notes

Resistant to Vancomycin; macrolides and tetracyclines are unreliable.
