Biosciences, Streatham Campus, Exeter
The Centre for Environment, Fisheries & Aquaculture Science (Cefas) and the University of Exeter have a Strategic Alliance that aims to combine the complementary capabilities and perspectives of both organisations.
This Alliance was further strengthened in 2018 via establishment of the Centre for Sustainable Aquaculture Futures (see: https://www.exeter.ac.uk/research/saf/).
A major component of the Alliance is to support joint PhD studentships. In accordance, we are pleased to announce the intention to fund one new PhD projects to start 26th September 2022 or 9th January 2023. This project is one of two projects that are in competition for funding from the University of Exeter and Cefas.
For eligible students the studentship will cover Home or international tuition fees plus an annual tax-free stipend of at least £16,062 for 3.5 years full-time, or pro rata for part-time study. The student would be based in Biosciences at the Streatham Campus in Exeter.
Antimicrobial resistance (AMR) is one of the biggest global challenges of our time. AMR is a complex problem that requires a united multisectoral approach1. Fortunately, over the last decade research has identified a new and novel class of antimicrobials produced by environmental bacteria4. These are effector molecules produced by bacterial secretion systems which kill neighbouring non-kin microbes. The Gram-negative bacterium Vibrio parahaemolyticus (Vp), present in marine and estuarine habitats, is an important human and animal pathogen that directly impacts the safety and trade of shellfish species as well as the global aquaculture sector. Recent genome sequencing has identified a vast array of antimicrobial effector genes linked to T6SSS within the genome of this species.
This PhD will study a unique strain collection of global Vp isolates. Specifically, the student will de novo whole-genome sequence strains from this collection, assemble the microbial genomes against known reference genomes and identify all antimicrobial effectors in silico.
This is a truly collaborative and interdisciplinary project and the student will work between Cefas and the UoE where they will characterise, in the laboratory, the effectiveness of the newly identified antimicrobials from the genome sequencing effort described above. This will be achieved by creating mutant strains that will have had the genes for the effectors removed, with subsequent study of the effector mutant strains in competition assays. The collaborative group at Exeter have state of the art fluorescence reporter strains of numerous clinical bacterial pathogens that can be utilised to investigate the effectiveness of the novel antimicrobials.
These strains are currently being utilised for such studies both in vitro and in vivo in the wax moth larvae model. The outputs from this project will provide a data-driven and translational approach to tackling the pressing global issue of AMR in addition to contributing to the Exeter/Cefas alliance’s goal of sustainable, healthy seafood.
