We investigated the effect of international travel on the gut resistome of 122 healthy travelers from the Netherlands by using a targeted metagenomic approach. Our results confirm high acquisition rates of the extended-spectrum β-lactamase encoding gene blaCTX-M, documenting a rise in prevalence from 9.0% before travel to 33.6% after travel (p<0.001). The prevalence of quinolone resistance enco...

In the past, the risk of human infection with parasites was considered to be limited to distinct geographic regions because of parasites’ adaptations to specific definitive hosts, select intermediate hosts and particular environmental conditions. These barriers are slowly being breeched—first by international travel developing...
