Mycobacterium lentiflavum is a nontuberculous, slowly growing mycobacterium usually recognized as a contaminant. Here, we report a case of disseminated M. lentiflavum infection responsible for hemophagocytic lymphohistocytosis in a heart-transplanted man.

Mycobacterium lentiflavum is a recently described nontuberculous mycobacterium that has mainly clinical importance in young children with cervical lymphadenitis and in immunocompromised patients. We describe a case of chronic pulmonary infection in an immunocompetent patient. Our observation confirms clinical, diagnostic, and treatment difficulties in the management of M. lentiflavum infection.

Mycobacterium lentiflavum, a slow-growing nontuberculous mycobacterium, is a rare cause of human disease. It has been isolated from environmental samples worldwide. To assess the clinical significance of M. lentiflavum isolates reported to the Queensland Tuberculosis Control Centre, Australia, during 2001-2008, we explored the genotypic similarity and geographic relationship between isolates fr...

BACKGROUND Mycobacterium lentiflavum (M. lentiflavum), a slow growing nontuberculous mycobacterium (NTM), has recently been described as an emerging human pathogen regardless of the immune status of the host. Previous reports have demonstrated that cervical lymphadenitis of children is the most frequent pathology of M. lentiflavum. However, there are little reports regarding pulmonary diseases ...

BACKGROUND Mycobacterium lentiflavum is rarely isolated in respiratory tract samples from cystic fibrosis patients. We herein describe an unusually high prevalence of M. lentiflavum in such patients. METHODS M. lentiflavum, isolated from the respiratory tract of cystic fibrosis patients, was identified using both rpoB partial sequencing and detected directly in the sputum by using real-time P...

non-tuberculosis mycobacteria (ntm), as certain species of mycobacteria, can affect human in several ways. in the preceding years, the rate of ntm detection has risen in both immunocompromised and immunocompetent patients. on the other hand, several reports have debated the possibility of co-infection of both mycobcateriu tuberculosis (mtb) and ntm in individuals that puts the role of ntm in di...

We report a rare case of lung disease caused by Mycobacterium lentiflavum in a previously healthy woman. A 54-year-old woman was referred to our hospital due to chronic cough and sputum. A computed tomography scan of the chest revealed bilateral bronchiectasis with bronchiolitis in the right middle lobe and the lingular division of the left upper lobe. Nontuberculous mycobacteria were isolated ...

A lymph node excision was performed on a 45-year-old woman with left cervical swelling. The disorder which developed after the patient had undergone oral surgery for a severe periodontal disease failed to respond to antimicrobial chemotherapy. A mycobacterial strain subsequently identified by high-performance liquid chromatography analysis of cell wall mycolic acids as Mycobacterium lentiflavum...

Three cases of human disease due to Mycobacterium lentiflavum are reported. In the first, the mycobacterium was responsible for chronic pulmonary disease in an elderly woman; in the second, it gave rise to cervical lymphadenitis in a child; and in the third, it caused a liver abscess in a young AIDS patient.

We announce the draft genome sequence of Mycobacterium lentiflavum strain CSUR P1491, a nontuberculous mycobacterium responsible for opportunistic potentially life-threatening infections in immunocompromised patients. The genome described here comprises a 6,818,507-bp chromosome exhibiting a 65.75% G+C content, 6,354 protein-coding genes, and 75 RNA genes.
