Knowing the species of nontuberculous mycobacteria (NTM) causing disease in a patient population can guide empiric treatment. In this study we aimed to determine the species of NTM causing disease in a selected patient population in Indonesia in order to guide empiric treatment. We retrospectively reviewed the records of all patients treated at 5 hospitals in Jakarta, Indonesia, diagnosed with NTM infection during January 2018- December 2019. The inclusion criterion for study subjects was having a positive test for NTM and the exclusion criterion was having a positive culture for Mycobacterium tuberculosis complex. Study subjects were confirmed to have NTM by a MPT64 rapid test. The species of NTM were identified by DNA sequencing of Mycobacterium 16S rRNA. A total of 15 patients were determined to have NTM at the study institutions during the study period, 53% male. The average age of study subjects was 45 (range: 4-83) years. The NTM positive specimens were obtained from the sputum (n = 5), skin and soft tissue biopsies (n = 5), and lymphoid tissue biopsies (n = 5). Of the 15 study subjects, 8 (53%) had M. abscessus, 5 (33%) had M. intracellulare, 1 (7%) had M. avium and 1 (7%) had M. cookii. Of the 5 NTM isolates from the sputum, 3 isolates were M. abscessus, 1 isolate was M. intracellulare and 1 isolate was M. Cookii. Of the 5 NTM isolates from skin and soft biopsies, 3 isolates were M. abscessus and the other 2 isolates were M. intracellulare. Of the 5 NTM isolates from lymphoid tissue biopsies, 2 isolates were M. abscessus, 2 isolates were M. intracellulare and 1 isolate was M. Avium. In our study, the most common NTIM isolate was M. abscessus. Empiric treatment of NTM in the study population should include coverage of M. abscessus. Further studies with larger numbers of subjects from multiple institutions are needed to determine if these findings hold true for other parts of Indonesia.
