<p>Plasmid-mediated colistin resistance gene <em>mcr-1</em> in <em>Escherichia coli</em> and <em>Klebsiella pneumoniae</em> isolated from market retail fruits in Guangzhou, China</p>

Abstract

We showed that <i>E. coli</i> GB110 can mediate the spreading of antibiotic resistance genes through the food chain, while <i>K. pneumoniae</i> GB015 was considered to be the progenitor of the most successful multidrug-resistant clone. Since fruits are usually consumed fresh, this may serve as a direct source of <i>mcr-1</i>-producing bacteria in humans that requires prompt surveillance and intervention to limit the spread of resistance.
