Mycobacterium malmoense is a Gram-positive bacterium from the genus Mycobacterium.

Contents

Etymology

From the city of Malmö, Sweden where the strain used for the description was isolated from patients.

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

  • First isolated from sputum and biopsy specimens with pulmonary disease in Malmö, Sweden.

    • Strain ATCC 29571 = CCUG 37761 = CIP 105775 = DSM 44163 = JCM 13391 = NCTC 11298.
