Abstract:
This prospective study evaluated the non-tuberculous mycobacteria (NTM) cases of lymphadenitis. A total of 76 isolates of mycobacteria were obtained from 200 lymph node aspirates suspected of tuberculosis, 74 of which were Mycobacterium tuberculosis, one was Mycobacterium fortuitum and one Mycobacterium kansasii. These results highlight the importance of NTM in HIV-negative patients as a case of lymphadenitis, and indicates the re-emergence of NTM as potential lymph node pathogens in this part of the country. Further studies on a larger scale are needed to delineate the association between NTM infections in HIV positive and negative subjects.
