Scientific Calendar Event



Description
An ICTP hybrid meeting

Antimicrobial resistance is a global threat to modern medicine, whereby bacteria evolve resistance to (i.e the ability to not be killed by) antibiotics. Since bacteria are able to pass chunks of DNA between unrelated individuals, this allows them to pass around genes encoding resistance mechanisms - in other words they can give each other an evolutionary head-start, directly donating the ability to survive an antibiotic in a process called Horizontal Gene Transfer.

Plasmids are key players in Horizontal Gene Transfer, acting as vehicles of antimicrobial resistance (AMR) spread, able to transfer tens of genes, and therefore multidrug resistance, in one event. It is therefore critical that we understand their biology, ecology and epidemiology.

Recent technology developments (longread sequencing and targeted bioinformatic tools) have led to improved ability to observe these processes, making thorough investigation of plasmid-mediated AMR outbreaks possible.
However, it has also highlighted how complex plasmid evolution is, the uniqueness of plasmid eco-evolutionary processes and the unsuitableness of many chromosome-based methods like point-mutation- and tree- based phylogenetics. New models are needed to be able to understand the processes that genomics allows us to observe and to appreciate their clinical and epidemiological implications in the light of plasmid evolution.
