Cutaneous nontuberculous mycobacterial infections in Japan: Review of the Japanese literature

Abstract

Nontuberculous mycobacteria (NTM) are acid-fast bacilli (AFB) other than Mycobacterium tuberculosis and Mycobacterium leprae, and are divided into rapidly growing mycobacteria (RGM) and slowly growing mycobacteria (SGM) based on their growth rate. They cause a wide range of infections, including cutaneous infections in both immunocompromised and immunocompetent patients. 1 Pulmonary NTM infections, the most frequent form of NTM infections, are increasing globally, 2 and cutaneous NTM infections have also increased nearly three-fold in 30 years since 1980 in Olmsted County, Minnesota. 3 There is also a report suggesting that the incidence of

Disseminated cutaneous Mycobacterium chelonae infection secondary to an indwelling catheter in an immunocompetent host

“…Mycobacterium chelonae is another RGM that has been isolated in soil, dust, water (both treated and untreated), as well as in some fish and amoebae [ [1] , [2] ]. Skin and soft tissue infections are the most common presentation of RGMs, and have been reported to be increasing in incidence in Japan and in the United States [ [1] , [2] , [3] , [4] ]. M. chelonae is known for causing disseminated cutaneous infection in immunocompromised individuals or localized cutaneous disease in the immunocompetent [ [2] , [5] ].…”

Mycobacterium marinum – Seltenes und Wichtiges

“…Bei immunkompetenten Personen treten lokalisierte Verlaufsformen auf, die üblicherweise als papulonoduläre Läsionen an den Akren imponieren [5, 6]. Eine Dissemination ist meist nur bei Immunsupprimierten zu beobachten [7].…”
