High rate of reinfection and possible transmission of complex in Northeast Thailand.

The complex (MAC) includes two main species of non-tuberculous mycobacteria (NTM), and These can cause serious disease, especially in immunocompromised patients. Little information is available concerning genetic diversity of NTM. We used multilocus sequence typing (MLST) based on a highly discriminative gene set to analyze MAC serially isolated from patients to determine the rate of MAC reinfection.
