About 18 heavy metal resistance genes (HMRGs) associated with arsenic, cadmium, copper, and mercury resistance were identified in 308 E. coli isolates through whole genome sequencing and advanced bioinformatics analysis. Researchers also examined 25 antibiotic-resistant bacterial genomes and discovered important links between HMRGs and antibiotic resistance genes (ARGs). Notably, 100% of the analyzed genomes carried at least one copy of 11 out of the 18 identified HMRGs. These findings suggest that environmental pollution may play a significant role in driving antimicrobial resistance. The study also highlights the potential of using bacterial resistance genes as biomarkers for environmental contamination and emerging public health risks.
