Is Mycobacterium found on skin?

Is Mycobacterium marinum serious?
For people with compromise of the immune system, M. marinum infection can be especially serious and involve disseminated (widespread) disease. If an infection is suspected under such circumstances, a health-care provider should be promptly consulted.
What is Mycobacterium marinum infection?
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.
Where is Mycobacterium marinum found?
Background. Mycobacterium marinum is an atypical Mycobacterium species found in cold or warm, fresh or salted water. M marinum infection occurs following skin and soft-tissue injuries that are exposed to an aquatic environment or marine animals.
What does Mycobacterium look like?
Mycobacteria are immobile, slow-growing rod-shaped, gram-positive bacteria with high genomic G+C content (61-71%). Due to their special staining characteristics under the microscope, which is mediated by mycolic acid in the cell wall, they are called acid-fast. This is also the reason for the hardiness of mycobacteria.
How is Mycobacterium marinum diagnosed?
Polymerase chain reaction (PCR) amplification techniques using Mycobacterium genus-specific primers can be used to diagnose M marinum infection directly in the biopsy sample. Tuberculin skin test using purified protein derivative is positive in 67%-100% of cases.
Is Mycobacterium marinum a rapid grower?
The pathogen Mycobacterium marinum, a faster growing close relative of Mycobacterium tuberculosis, has a single rRNA operon per genome. FEMS Microbiol Lett.
Is Mycobacterium a fungus or bacteria?
Mycobacteria are characterized by the possession of very thick, waxy, lipid-rich hydrophobic cell walls. Being hydrophobic, they tend to grow as fungus-like pellicles on liquid culture media: hence the name Mycobacterium – ‘fungus bacterium.
What is the difference between Mycobacterium and mycobacteria?
They are generally nonmotile bacteria, except for the species Mycobacterium marinum, which has been shown to be motile within macrophages. They are characteristically acid-fast. Mycobacteria have an outer membrane. They possess capsules, and most do not form endospores.
How do you treat atypical mycobacterial infection?
Treatment of atypical mycobacterial infections depends upon the infecting organism and the severity of the infection. In most cases a course of antibiotics is necessary. These include rifampicin, ethambutol, isoniazid, minocycline, ciprofloxacin, clarithromycin, azithromycin and cotrimoxazole.
What is Mycobacterium marinum?
What is Mycobacterium marinum? Mycobacterium marinum (M. marinum) is a slow-growing atypical mycobacterium that is commonly found in bodies of fresh or saltwater in many parts of the world. Skin infections with Mycobacterium marinum in humans are relatively uncommon and are usually acquired from contact with contents of aquariums or fish.
What antibiotics treat Mycobacterium marinum infection?
Top Mycobacterium Marinum Related Articles Arthritis Arthritis is inflammation of one or more joints. clarithromycin Clarithromycin (Biaxin, Biaxin XL) is an antibiotic drug prescribed for the treatment of a large variety of bacterium. Osteomyelitis Osteomyelitis is an infection of the bone.
What are the signs of Mycoplasma marinum infection?
The first signs of infection with M. marinum include a reddish or tan skin bump called a granuloma. Less commonly, a string or batch of the small reddish bumps crop up on the exposed body area in a classic pattern called sporotrichotic lymphangitis.
What is the prevalence of Mycoplasma marinum infection?
Although rare, infections can occur worldwide, most commonly in individuals with occupational and recreational exposure to fresh or saltwater. In the United States, infections caused by M. marinum are rare. The infection is very rare in children and is typically a disease of adults, although any person, regardless of age, may become infected.
