Summary
Three cases of Mycobacterium marinum skin infections, likely from home aquariums, were analyzed. Treatment approaches varied, with some patients achieving remission through antibiotics or even without intervention.
Area of Science:
- Dermatology
- Infectious Diseases
- Microbiology
Background:
- Mycobacterium marinum is an aquatic bacterium known to cause skin infections in humans.
- Exposure often occurs through contact with contaminated water, particularly from home aquariums or fish tanks.
Observation:
- This report details three distinct cases of cutaneous Mycobacterium marinum infection.
- All affected individuals had a history strongly suggestive of exposure through home aquariums.
- One patient yielded M. marinum upon culturing a biopsy from a skin lesion.
Findings:
- Clinical remission was observed across different treatment strategies.
- Successful outcomes included antituberculous triple therapy, trimethoprim-sulfamethoxazole treatment, and spontaneous resolution without specific medical intervention.
Implications:
- The findings highlight the importance of considering Mycobacterium marinum in the differential diagnosis of skin lesions associated with aquarium exposure.
- Diverse therapeutic outcomes suggest a need for individualized treatment approaches for M. marinum infections.
- Public awareness regarding safe aquarium handling practices may help prevent such infections.
