Antimicrobial Resistance, Metal Tolerance, and Virulence Determinants in Gram-negative Opportunistic Pathogens Isolated from Brazilian Groundwater
Groundwater is a critical freshwater resource, but its quality can be compromised by anthropogenic contamination. Metals may exert selective pressure on microbial communities, promoting metal-tolerant bacteria carrying metal tolerance genes (MTGs), which are often associated with antimicrobial resistance genes (ARGs) a...
