Mycobacterium lentiflavum infection

Tuesday 1 February 2011

Definition: Mycobacterium lentiflavum is a recently described nontuberculous mycobacterium (NTM) that has mainly clinical importance in young children with cervical lymphadenitis and in immunocompromised patients.

A case of chronic pulmonary infection has been described in an immunocompetent patient.

Mycobacterium lentiflavum was described as a nontuberculous mycobacterium in 1966.

Most of the isolates represented fortuitous isolations, although recently its identification has posed concerns about its possible clinical importance.

M. lentiflavum was mainly isolated from lymph nodes of young children, while isolations from other sites (lung specimens included) were described only in immunocompromised patients.
