- Be sure to cover any open cuts, scrapes or abrasions, and wear heavy or waterproof gloves when cleaning fish, fish tanks or equipment.
How do you identify Mycobacterium Marinum?
Diagnosis is essentially made through histological examination and culture. The laboratory staff should always be notified that M. marinum is suspected, so that Lowenstein-Jensen agar cultures at 28°-32°C, besides those at 37°C, are prepared. The material should be left 6 weeks in the agar.
What disease is caused by Mycobacterium marinum?

What can Mycobacterium marinum cause?
Mycobacterium marinum is a non-tuberculous mycobacterium that causes a tuberculosis-like illness in fish and can infect humans when injured skin is exposed to a contaminated aqueous environment.
How do you treat Gram-positive mycobacteria?
The lipoglycopeptide dalbavancin is a long-acting agent for treating acute bacterial skin and skin structure infections caused by a broad range of Gram-positive pathogens. Recent studies have shown promising activity of dalbavancin against Gram-positive biofilms, including methicillin-resistant S.
How long does it take to cure Mycobacterium?
