Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

International travel is well reported to be associated with acquisition of multidrug-resistant organisms, however, the impact of colonization of these multidrug-resistant organisms is currently uncertain. As colonization of multidrug-resistant organisms had been demonstrated to be associated with distinct intestinal microbiota composition and travellers constitute a generally healthy population with minimal antibiotics exposure; by evaluating serial stool samples before and after travel, the investigators can delineate a potential causal relationship between host intestinal microbiota and subsequent risk of acquisition of multidrug-resistant organisms.
