Research Reveals Amplified Antibiotic Resistance Gene Copies in Humans and Livestock
Unveiling a Crucial Link Biomedical engineers at Duke University have made a groundbreaking discovery linking the proliferation of antibiotic-resistance genes with the evolution of resistance to new drugs in specific pathogens. Their research sheds light on how bacteria exposed to heightened levels of antibiotics often carry multiple identical copies of protective antibiotic resistance genes . These duplicated genes, often associated with mobile genetic elements known as transposons, facilitate the spread of resistance and provide a platform for the evolution of resistance to novel drugs. The findings, published in Nature Communications on February 16, underscore the urgent need for understanding the mechanisms driving antibiotic resistance evolution. Insights from Advanced Technology Previous studies by the Lingchong You lab have shown that a significant portion of bacterial pathogens can transmit antibiotic resistance through horizontal gene transfer. Despite this, the presence of an...
