CompletedMolecular Epidemiology and Microbial Metagenomics

Assessment of the Diversity of Bacteria with Antibiotic-Resistance Genes in the Virilla River in Costa Rica

Start: abril de 2023

To assess the diversity of bacteria carrying antibiotic resistance genes in the Virilla River, with the aim of providing an initial description of the richness and abundance of these microbial groups in an aquatic ecosystem heavily impacted by pollutant discharges.
