Mycobacterium marinum is a ubiquitous waterborne organism that mainly causes skin infection in immunocompetent patients, and its disseminated infection is rare. Extranodal NK/T cell lymphoma, nasal type (ENKL) usually localizes at the nasal and/or paranasal area, but occasionally disseminates into the skin/soft tissue and gastrointestinal tract. Compromised immunity is a risk factor for develop...

An 81-year-old male with myasthenia gravis developed a cutaneous infection with Mycobacterium marinum, which apparently resolved following local heat therapy. Five months later, the patient developed new skin lesions and pancytopenia. M. marinum was isolated from his bone marrow. Pulsed-field gel electrophoresis was performed to determine if the skin and bone marrow isolates were clonally relat...

The patient developed a lesion on his right hand after sustaining an abrasion while he cleaned his boat, which progressed to formation of other lesions that spread proximally on his right arm and resulted in an abscess to his right elbow. In this case report, we will discuss the patient’s history and clinical assessment, the timeline, the clinical course and interventions, and the epidemiology ...

Mycobacterium marinum isolates cultivated from tissue containing granulomatous lesions in Florida pompano Trachinotus carolinus and from biofilm samples collected from their tank and water recirculating system had identical (L1 of 11 bands) repetitive-sequence-based polymerase chain reaction (rep-PCR) DNA fingerprints. A second M. marinum clone sharing 4 of 11 rep-PCR bands with the first clone...

We report the case of a 35-year-old man with a chronic ulceration of the hand in whom an infection with Mycobacterium marinum was diagnosed. Clarithromycin and doxycycline were prescribed, resulting in a slow resolution of the ulceration. M. marinum is a nontuberculous mycobacterium that causes skin lesions such as nodules, ulcerations, and sporotrichoid spread, but may also be responsible for ...

background: mycobacterium marinum infection has a worldwide distribution and the organism occupies many aquatic environments. infections in human consist of nodular cutaneous lesions that can progress to tenosynovitis, arthritis, and osteomyelitis. case presentation: a 27-year-old man was presented with a history of swelling and exudative erythematous lesions and pustules of the right forearm. ...

to evaluate and compare the chlorophyll content, carotenoid, protein, peroxidase and polyphenol oxidase in different barley species in iran, 49 genotypes belonging to 5 barley species were employed in a completely randomized design with three replications in greenhouse conditions. a high level of within and between species variation was detected. in all the species, significant positive correla...

Disseminated infection due to Mycobacterium marinum is rare but has been described in immunosuppressed and transplant recipients. We describe a case of multifocal osteoarticular involvement by this pathogen in a patient with anorexia nervosa. Serial surgical debridements and a prolonged course of antimicrobial therapy including intravenous amikacin, imipenem, and oral ethambutol and azithromyci...

Although Mycobacterium marinum and Mycobacterium tuberculosis are very closely related they differ significantly in their growth rates. The Type strain of M. marinum and one clinical isolate were investigated and, like M. tuberculosis, were found to have a single rRNA (rrn) operon per genome located downstream from murA gene and controlled by two promoters. No sequence differences were found th...
