Archive description
We used untargeted metagenomic Illumina sequencing to study fecal samples of 35 Swedish healthcare students, taken before and after embarking on a student exchange program to the Indian peninsula or central Africa. The students were not taking antibiotics between sampling points. Antibiotic resistance gene frequencies were investigated in all samples.
How this project entered the registry
