A study by researchers at Washington University School of Medicine in St. Louis suggests that international travelers are bringing home new and potentially deadly strains of antimicrobial resistant superbugs in their gut microbiomes. The scientists, collaborating with researchers at Maastricht University, analyzed bacterial communities in the gut microbiomes of 190 Dutch adults before and after travel to Southeastern Asia, South Asia, North Africa and Eastern Africa, which are all regions where the prevalence of resistance genes is high. The results confirmed that international travelers commonly return home with an unexpected payload of new bacterial strains among the thousands that normally reside within the gut microbiome.
