High mycobacterial diversity in recreational lakes

Abstract : Although nontuberculous mycobacteria (NTM) are natural inhabitants of freshwater ecosystems, few studies have focused on their distribution in these habitats. Thus, the knowledge about the abundance as well as the composition of NTM remains limited and patchy in these environments. In this context, a prospective study was performed to identify favourable habitats for mycobacteria in two recreational lakes. Mycobacterial density and diversity were measured using quantitative real-time PCR and the MiSeq Illumina platform. For both lakes, five compartments were investigated, i.e. water column, air–water interface, sediment, epilithon and epiphyton biofilms. Nontuberculous mycobacteria were detected in all compartments in large densities and displayed a remarkable diversity. NTM were dominated by fast-growing species. Lakes and compartments appeared to shape mycobacteria assemblage composition as well as their densities. In both lakes, some OTUs assigned to the species level were identified as related to known opportunistic pathogens.
