High acquisition rate of extended-spectrum β-lactamase-producing Enterobacteriaceae among French military personnel on mission abroad, without evidence of inter-individual transmission

Acquisition of extended-spectrum β-lactamase-producing Enterobacteriaceae (ESBL-E) by Europeans travelling individually in high-endemicity countries is common. However, how the different ESBL-E strains circulate in groups of travellers has not been studied. We investigated ESBL-E transmission within several groups of French military personnel serving overseas for 4-6 months.We conducted a prospective study among French military personnel...
