Abstract:
Erysipelothrix rhusiopathiae is a facultative anaerobic Gram-positive rod that occurs widely in nature and is best known in veterinary medicine for causing swine erysipelas. In humans, infections are rare and mainly considered as occupationally acquired zoonosis. A case of E. rhusiopathiae bacteremia most likely associated with home freshwater aquarium handling is reported. The route of transmission was probably a cut with the dorsal fin of a dead pet fish. A short review of clinical presentations, therapeutic considerations and pitfalls of E. rhusiopathiae infections in humans is presented.
Insights
Erysipelothrix rhusiopathiae, a bacterium known for causing swine erysipelas, can infect humans, often through occupational exposure. This case highlights a rare instance of bacteremia linked to handling home freshwater aquariums.
Area of Science:
- Microbiology
- Infectious Diseases
- Zoonosis
Background:
- Erysipelothrix rhusiopathiae is a Gram-positive bacterium prevalent in nature.
- It is a common cause of swine erysipelas in veterinary medicine.
- Human infections are infrequent, typically resulting from occupational zoonotic transmission.
Observation:
- A case of Erysipelothrix rhusiopathiae bacteremia is reported.
- The infection was likely associated with handling a home freshwater aquarium.
- Transmission may have occurred via a cut from a dead pet fish's fin.
Findings:
- This report details a rare instance of human E. rhusiopathiae bacteremia.
- The likely transmission route involved contact with a freshwater aquarium pet.
- The study reviews clinical presentations and treatment challenges for human infections.
Implications:
- Highlights a potential non-occupational zoonotic transmission route for E. rhusiopathiae.
- Emphasizes the need for awareness of E. rhusiopathiae risks in non-traditional settings like home aquariums.
- Underscores the importance of prompt diagnosis and appropriate management of rare bacterial infections.
