Mycobacterium interjectum as Causative Agent of Cervical Lymphadenitis

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 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...

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...

Mycobacterium bohemicum and Cervical Lymphadenitis in Children

To the Editor: Members of the genus Mycobacterium are well-established causes of granulomatous lymphadenitis in children. M. bohe-micum was fi rst described in 1998 in a patient with Down syndrome (1). The organism is characterized by a unique 16S rRNA gene sequence (1) and has been isolated from humans, animals, and the environment (2). Published data on M. bohemicum are limited to the origina...
