Overview
Erysipeloid is an occupational infection of the skin caused by traumatic penetration of Erysipelothrix rhusiopathiae. The disease is characterized clinically by an erythematous oedema, with well-defined and raised borders, usually localized to the back of one hand and/or fingers. Vesicular, bullous and erosive lesions may also be present. The lesion may be asymptomatic or accompanied by mild pruritus, pain and fever. In addition to cutaneous infection, E. rhusiopathiae can cause endocarditis, which may be acute or subacute. Endocarditis is rare and has a male predilection. It usually occurs in previously damaged valves, predominantly the aortic valve. Endocarditis does not occur in patients with valvular prostheses and is not associated with intravenous drug misuse. Diagnosis of localized erysipeloid is based on the patient's history (occupation, previous traumatic contact with infected animals or their meat) and clinical picture (typical skin lesions, lack of severe systemic features, slight laboratory abnormalities and rapid remission after treatment with penicillin or cephalosporin).
In humans, Erysipelothrix rhusiopathiae infections most commonly present in a mild cutaneous form known as erysipeloid[1] or fish poisoning.[2] E. rhusiopathiae can cause an indolent cellulitis, more commonly in individuals who handle fish and raw meat.[3] It gains entry typically by abrasions in the hand. Bacteremia and endocarditis are uncommon but serious sequelae.[4][5] Due to the rarity of reported human cases, E. rhusiopathiae infections are frequently misidentified at presentation.[1]

Treatment
The treatment of choice is a single dose of benzathine benzylpenicillin given by intramuscular injection, or a five-day to one-week course of either oral penicillin or intramuscular procaine benzylpenicillin.[6] Erythromycin or doxycycline may be given instead to people who are allergic to penicillin. E. rhusiopathiae is intrinsically resistant to vancomycin.[6]

Prevention
Antimicrobial Regimen
- Preferred regimen (1): Penicillin 500 mg qid for 7–10 days
- Preferred regimen (2): Amoxicillin 500 mg tid for 7–10 days
- Erysipelothrix rhusiopathiae [7]
- 1. Erysipeloid of Rosenbach (localized cutaneous infection)
- Preferred regimen (1): Penicillin G benzathine 1.2 MU IV single dose
- Preferred regimen (2): Penicillin VK 250 mg PO qid for 5-7 days
- Preferred regimen (3): Procaine penicillin 0.6-1.2 MU IM qd for 5-7 days
- Alternative regimen (1): Erythromycin 250 mg PO qid for 5-7 days
- Alternative regimen (2): Doxycycline 100 mg PO bid for 5-7 days
- 2. Diffuse cutaneous infection
- Preferred regimen: See localized infection
- 3. Bacteremia or endocarditis
- Preferred regimen: Penicillin G benzathine 2-4 MU IV q4h for 4-6 weeks
- Alternative regimen (1): Ceftriaxone 2 g IV q24h for 4-6 weeks
- Alternative regimen (2): Imipenem 500 mg IV q6h for 4-6 weeks
- Alternative regimen (3): Ciprofloxacin 400 mg IV q12h for 4-6 weeks
- Alternative regimen (4): Daptomycin 6 mg/kg IV q24h for 4-6 weeks
- Note: Recommended duration of therapy for endocarditis is 4 to 6 weeks, although shorter courses consisting of 2 weeks of intravenous therapy followed by 2 to 4 weeks of oral therapy have been successful.
