MICROBIOLOGY

  • Mycobacterial species
  • Slow grower (2-6 weeks for positive with liquid media), photochromogen.
  • DNA analysis suggests there may be 5-7 subspecies.
    • Subtype I appears to be responsible for most human infection.
    • M. tuberculosis and M. kansasii can occur together: cultures positive for M. kansasii should be incubated for prolonged periods to exclude M. tuberculosis, which grows slightly slower than M. kansasii.
  • Reservoir appears to be water with likely infection via aerosol
