Mycobacterium mantenii is a bacterium in the Mycobacterium family. The genus includes species known to cause serious diseases in mammals, including tuberculosis and leprosy,[2] but this species belongs to the generally less pathogenic nontuberculous mycobacteria.

Description

edit

Gram-positive, nonmotile, short and acid-fast rods. No cording, spores or filaments.

Colony characteristics

  • Smooth colonies after 7 or more days of incubation.
  • Colonies grown in dark or in light are pigmented, with bright yellow pigmentation (scotochromogenic).

Differential characteristics

Mycobacterium mantenii was first described in 2009, after it had been isolated from clinical samples in the Netherlands as well as from a water sample of the Zambezi river in Zambia. The clinical isolates were cultured from two children suffering from cervical lymphadenitis, most likely caused by Mycobacterium mantenii. The remaining two clinical isolates were cultured from respiratory samples in two elderly patients and were unlikely to have any clinical significance. Genetically, Mycobacterium mantenii is most closely related to M. scrofulaceum. Mycobacterium scrofulaceum, too, is mainly a causative agent of lymphadenitis in children and generally of little significance when isolated from respiratory samples. Mycobacterium mantenii was named after Dr. Adriaan Manten, an influential microbiologist in the Netherlands, who described the first cases of disease caused by nontuberculous mycobacteria in the Netherlands and who performed important research on drug susceptibility of nontuberculous mycobacteria.


  • First isolated from human lymph node samples, pulmonary secretions and environmental samples.
