Research Project: The co-selection of mercury and antibiotic resistance genes in the fish microbiome

Keywords: Antibiotics resistance, mercury contamination, gene transfer

The spread of antibiotic resistance genes is one of the biggest threats to human wellbeing of our time. Our lab explore the possibility that selection of mercury resistant bacteria in contaminated environments may lead to the co-selection of antibiotic resistance due the genetic linkage of resistance genes on mobile genetic elements.
