MICROBIOLOGY

  • M. celatum: slow growing (3-8 wks to culture). May cause false positive M. tuberculosis direct (MTD) test.
  • M. genavense: very slow grower; difficult to grow; alert lab if M. genavense suspected.
  • M. haemophilum: slow growing; alert lab if suspected since requires hemin or iron to grow in culture and grows best at 28-30°C.
  • M. malmoense: slow growing; most clinical isolates/reports from northern Europe.
  • M. mucogenicum: rapidly grows (< 7 days in culture); sporadic contaminant in respiratory samples; water is environmental reservoir. Previously known as M. chelonae-like organism.
  • M. simiae: growth may take 4-6 weeks on LJ slants.
  • M. szulgai: scotochromagen at 37ºC, and a photochromogen at 25ºC.
