<p>Researchers have uncovered a key link between the spread of antibiotic resistance genes and the evolution of resistance to new drugs in certain pathogens. Bacteria exposed to higher levels of antibiotics often harbor multiple identical copies of protective antibiotic resistance genes which are linked to &ldquo;jumping genes&rdquo; that can move from strain to strain. Duplicate genes provide a mechanism for resistance to spread &nbsp;and enable evolving resistance to new drugs.</p>
