Distribution, prevalence of non-tuberculous mycobacteria on Hainan Island and antibiotic resistance of <i>Mycobacterium abscessus</i>.

ABSTRACT: Non-tuberculous mycobacteria (NTM) infections are increasingly recognized as a public health concern, yet their distribution and antibiotic resistance patterns on Hainan Island, China's tropical hotspot, remain understudied. This study analyzes 158 clinical respiratory samples from 2015 to 2018 across 14 cities, identifying 118 NTM isolates from 24 species. Predominant species include Mycobacterium abscessus (23.73%), M. intracellulare (22.03%), and M. simiae (14.41%). Spatial mapping reveals elevated prevalence in coastal areas, with no significant north-south divergence on the island (Bray-Curtis dissimilarity: 0.5954, P = 0.694), but substantial differences from mainland China (North: 0.9604, P = 0.0011; South: 0.9340, P = 0.0013).
