Increased antimicrobial resistance among non-typhoidal Salmonella infections in international travellers returning to the Netherlands

We observed increased AMR levels among SE infections in international travellers returning to the Netherlands, particularly for ampicillin, (fluoro)quinolones and tetracycline. Our results also suggest that AMR among SE infections is significantly more likely to occur abroad, specifically outside the EU/EEA, whereas AMR levels among ST/STM infections have relatively less pronounced differences associated with travel history. This is largely consistent with previous reports in high-income countries^5,7 and stresses the importance of considering travel history when patients with NTS infection require empiric antimicrobial treatment.
