Mycobacterium psychrotolerans is a rapidly growing mycobacterium first isolated from pond water near a uranium mine in Spain. It was able to grow at 4°C and is therefore considered to be psychrotolerant. Etymology: psychros, cold; tolerans, tolerating.
Description
[edit]Microscopy
- Gram-positive, acid-fast, non-spore-forming, non-motile short rods.
Colony characteristics
- Smooth, entire, bright orange, scotochromogenic colonies appear after 2 days in GYEA, Bennett's and nutrient agars.
Physiology
- Growth on Lowenstein–Jensen agar is moderate.
- No growth occurs on MacConkey agar.
- Grows at 4–37C and tolerates 7% NaCl.
- The type strain is resistant to ampicillin, cefuroxime, cloxacillin, erythromycin, penicillin and polymyxin. Sensitive to ciprofloxacin, gentamicin, neomycin and oxytetracycline.
Differential characteristics
- Growth at 4°C.
Pathogenesis
[edit]- First isolated from an environmental source, not known to be pathogenic.
Type strain
[edit]- The type strain was isolated from a pond in Salamanca, Spain.
- Strain WA101 = DSM 44697 = JCM 13323 = LMG 21953
