A bioinformatics approach to antimicrobial resistance and gene transfer.
Bioinformatics Approach to Antimicrobial Resistance & HGT takes a genomics-and-methods view of one of the great public-health challenges. You learn the bioinformatic workflow for AMR: identifying resistance genes and their genetic context, and — distinctively — reconstructing horizontal gene transfer to understand how resistance moves between organisms via plasmids and mobile elements. The course connects these analyses to surveillance and the wider dynamics of resistance spread. You finish able to reason about a bioinformatics investigation of AMR and its transmission.

This course covers a bioinformatics approach to antimicrobial resistance (AMR) and horizontal gene transfer (HGT) — analysing genomic data to find resistance genes and trace their spread.
1. Identify resistance genes and their genetic context.
2. Analyse mobile elements and plasmids.
3. Reconstruct horizontal gene transfer events.
4. Trace how resistance spreads between organisms.
5. Connect analysis to AMR surveillance.
