Mycobacterium cookii

Description

• Colonies are smooth and glistening with yellow-orange pigmentation.

• Slow growth on Löwenstein-Jensen medium or Middlebrook 7H10 agar at 31 °C. No growth at 37 °C, 42 °C or 45 °C.
• Most of the strains are susceptible to ethambutol, isoniazid, streptomycin, and rifampin.

• Phylogenetic position between the slowly growing pathogenic species and the saprotrophic rapidly growing species by partial 16S rDNA sequencing.

  Pathogenesis

• Not pathogenic for humans, mice, guinea pigs and rabbits. Biosafety level 1.
• Provokes a non-specific hypersensitivity reaction to bovine tuberculin.
