High risk of intestinal colonization with ESBL-producing Escherichia coli among soldiers of military contingents in specific geographic regions

AbstractOne-hundred Polish soldiers of a contingent in Afghanistan in 2019 were screened forEnterobacterales resistant to newer-generationβ-lactams at their departure and return. Seventeen percent were colonized in the gut at the departure, whereas 70% acquired carriage in Afghanistan. The commonest organisms were extended-spectrumβ-lactamase (ESBL)-producingEscherichia coli (ESBL-Ec; 96.6%). All isolates were sequenced and were clonally diverse overall, even within the same sequence type, indicating that independent acquisitions mainly. ESBL-Ec were often multi-drug-resistant. Soldiers stationing in certain regions are at high risk of acquiring resistant bacteria that may cause endogenous infection, be transmitted to vulnerable individuals, and spread resistance genes.
