Mycobacterium lentiflavum: An Etiologic Agent of Cervical Lymphadenitis

Mycobacterium lentiflavum as an emerging causative agent of cervical lymphadenitis.

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...

Mycobacterium interjectum as causative agent of cervical lymphadenitis.

A mycobacterial strain isolated from a lymph node of a 3-year-old female with cervical lymphadenitis was identified as Mycobacterium interjectum by means of sequencing of the 16S rRNA gene. Analysis of this case and previously published cases demonstrates the importance of M. interjectum as a causative agent of cervical lymphadenitis in young children.

Mycobacterium avium complex cervical lymphadenitis in an immunocompetent adult patient.

Nontuberculosis mycobacterial cervical lymphadenitis is a relatively common disease in immunocompetent children but a rare disease in immunocompetent adults. We report the diagnosis and treatment of Mycobacterium avium complex cervical lymphadenitis in an adult female. Our evaluation of immune competence, including gamma interferon (IFN-gamma) and interleukin-12 (IL-12) signaling, found no evid...

Cervical lymphadenitis due to Mycobacterium bohemicum.

Acute Cervical Lymphadenitis Caused by Mycobacterium florentinum

To the Editor: The incidence of nontuberculous mycobacterium (NTM) lymphadenitis appears to be rising, likely because of improved diagnostic techniques. Mycobacterium avi-um-intracellulare is the most common etiologic agent of NTM lymphadenitis in children (1,2). Newer diagnostic methods, including DNA sequencing, have identifi ed cervical adenitis secondary to other slow-growing species (M. le...
