About the Project

Applications are invited from graduates in Microbiology or other relevant biomedical sciences (First or Upper Second) to work with Antimicrobial Research UK (ANTRUK) on Re-purposing β-lactam Combination Therapies as a Precision Treatment for Gram-negative Infections. This 3 year studentship will commence in September 2022 and be based at the Blizard Institute within the School of Medicine and Dentistry.

We have identified a potent synergistic antimicrobial interaction when cefepime is combined with sulbactam against multi-drug resistant Acinetobacter spp and Enterobacterales strains in-vitro (Wareham et, al 2020). Activity of the combination has been confirmed in a national surveillance study (MUTATE) conducted by ANTRUK using a disc diffusion assay developed for rapid susceptibility testing. A pharmacodynamic hollow-fibre dose ranging study is underway (Prof J Standing, UCL Precision Medicine) to determine the optimal formulation for the treatment of MDR Gram-negative infections. Progression of cefepime / sulbactam towards clinical use and a licensed indication requires further studies to inform on dosing, comparative activity, resistance potential, toxicology and clinical efficacy. These issues will be addressed as part of the experimental work to be undertaken in this 3-year PhD studentship.

Interviews to be held on Monday 5th September 2022
