Mycobacterium lentiflavum
Etymology: Lentus from Latin for slow, flavus, Latin for yellow.
Gram-positive, nonmotile and acid-fast coccobacilli.
Colony characteristics
- Smooth colonies, with bright yellow pigmentation 1-2mm in diameter.
Physiology
- Slow growth on Löwenstein-Jensen medium at temperatures between 22 °C and 37 °C within 3–4 weeks.
- Generally resistant to isoniazid, rifampin, ethambutol and streptomycin.
Differential characteristics
- Phylogenetic analysis, based on an evaluation of 16S rDNA sequences, places M. lentiflavum in an intermediate position between rapidly and slowly growing mycobacteria, closely related to Mycobacterium simiae and Mycobacterium genavense.
Pathogenesis
- In young children with cervical lymphadenitis and in immunocompromised patients[1]
- One case of vertebral osteomyelitis reported
- Biosafety level 2
