Nontuberculous mycobacteria diversity and distribution in tropical freshwater systems in French Guiana are mainly driven by habitat type, sample type, and sediment phosphorus, with species-specific effects.
- Why it matters: Their environmental diversity and spatial patterns in tropical freshwater settings are poorly characterized, limiting prediction of disease emergence and transmission.
- What they did: Using eDNA-based metabarcoding across tropical freshwater ecosystems in French Guiana and comparing with Côte d’Ivoire, the study tested microhabitat abiotic and biotic drivers and assessed co-occurrences across contexts.
- The result: Mycobacteria show stratified patterns by sediment texture and depth, and ecological interactions appear to occur at the microhabitat level rather than following clear biogeographic patterns.
