PURPOSE: Mycobacterium other than tuberculosis (MOTT) are mycobacterial species that may cause human disease, but do not cause tuberculosis. It is an uncommon organism that has been reported in 2 out of 100,000 persons in the United States. In our institution, the incidence of a positive MOTT culture is not known. It is the objective of this study to determine the prevalence rate of MOTT in a referral university hospital in the Philippines for which tuberculosis is suspected.

METHODS: Specimens submitted for culture and sensitivity studies for Mycobacterium tuberculosis for which isolates of Mycobacterium other than tuberculosis grew using the BACTEC (Becton-Dickinson) method or Mycobacteria Growth Indicator Tube (MGIT) were included in the study.

RESULTS: For the period of January 1, 2003 up to June 30, 2009, there were 2,714 specimens submitted for Mycobaterium culture, of which 59 (2.17%) were isolated for MOTT. Majority of which were from respiratory sources (n=48, sputum; 3, bronchial washing; and 1, bronchial aspirate) while minority were from varied sources (n= 2, urine; 1, lymph node; 1 lung tissue; 1, mediastinal aspirate; 1 subcutaneous tissue; 1, CSF).

CONCLUSION: There is a low incidence of positive culture for Mycobaterium other than tuberculosis in our institution.

CLINICAL IMPLICATIONS: Although there is a low incidence of MOTT in patients suspected to have tuberculosis, species identification in Mycobacterium is still important because of difference in treatment regimen.
