Mycobacterium malmoense is a bacteria.
Etymology: malmoense, from the city of Malmö, Sweden where it was first isolated.
Description
Gram-positive, nonmotile, acid-fast and coccoid to short rods.
- Environmental reservoir: soil and water.
Colony characteristics
- Smooth and nonpigmented colonies, growth below the surface of semisolid agar medium after deep inoculation (as seen with M. bovis), 0.9 - 1.7mm in diameter.
Physiology
- Growth on inspissated egg medium and oleic acid-albumin agar at a temperature range of 22°C-37°C requires over 1 week.
- Susceptible to ethambutol, ethionamide, kanamycin and cycloserine.
Differential characteristics
- Antigenic structure: seroagglutination demonstrates a single serovar distinct from that of other species.
Pathogenesis
- Usually infects young children with cervical lymphadenitis or adults with chronic pulmonary disease, (mostly with previously documented pneumoconiosis).
- Rarely causes extrapulmonary diseases and disseminated infections
- Biosafety level 2
Type Strain
Strain ATCC 29571 = CCUG 37761 = CIP 105775 = DSM 44163 = JCM 13391 = NCTC 11298.
Treatment
Antimicrobial regimen
- in vitro [1]
- Susceptible: Ethambutol, Ethionamide, Kanamycin, and Cycloserine
- Resistant: INH, Streptomycin, Rifampin, and Capreomycin
- Pulmonary M. malmoense infection
- Preferred regimen: INH AND Rifampin AND Ethambutol ± Quinolones AND Macrolides
