Surface water bacterial community structure in the Penas Blancas river basin, Alajuela, Costa Rica.
This study aims to investigate the bacterial community structure, using 16S rRNA gene metabarcoding, from surface water samples taken along the Penas Blancas river basin, the habitat of the otter (Lontra longicaudis), to discern the links between bacterial community composition and the presence of antimicrobial residues and ARGs.
