Professor Matthew Avison

I lead a research group studying antimicrobial drug resistance (AMR) in bacteria. We use molecular genetics, biochemistry and functional genomics techniques to identify and characterise AMR mechanisms in key human pathogens, their mobilisation, and their control. We then use this information to combat the problem of AMR by developing interdisciplinary research collaborations. 

Our current basic work aims to characterize multi-drug resistance mechanisms in non-fermenting Gram-negative bacteria, particularly Stenotrophomonas maltophilia and in Enterobacteriaceae, particularly Escherichia coli and Klebsiella pneumoniae. We have studied mechanisms of β-lactam and β-lactam/β-lactamase inhibitor resistance (e.g. Takebayashi et al., (2019) Antimicrob Agents Chemother; Calvopiña et al., (2018) Antimicrob Agents ChemotherJiménez-Castellanos et al., (2018) J Antimicrob Chemother; Calvopiña et al., (2017) Molecular Microbiology), aminoglycoside resistance (e.g. Calvopiña et al., (2019) Antimicrob Agents Chemother) and fluoroquinolone resistance (e.g. Wan nur Ismah et al., (2018) J Antimicrob Chemother; Jiménez-Castellanos et al., (2016) J Antimicrob Chemother).

We are collaborating with chemists and structural biologists to develop β-lactamase inhibitors (e.g. Brem et al., (2014) Nature Chemistry; Brem et al., (2016) Nature Communications; Li et al., (2017) Chem CommunHinchliffe et al., (2018) BiochemistryCahill et al., (2019) Biochim Biophys Acta), chemical modifications that increase the entry of antibiotics into Gram negative bacteria (e.g. Calvopiña et al., (2016) Antimicrob Agents Chemother) and ways of reversing fluoroquinolone resistance by inhibiting DNA repair (e.g. Wilkinson et al., (2016) eLife). We are also part of Bristol University's "Silent Pharmacy" consortium led by Dr Andy Bailey (Biological Sciences) and are working in collaboration with chemists, biochemists and mycologists to identify novel antibiotics from fungi.

We have pioneered proteomics-based technologies for the identification of AMR proteins in clinical samples and we are pioneering the use of proteomics to improve the ability of whole genome sequencing to predict antimicrobial susceptiblity (e.g. Wan Nur Ismah et al., (2018) Antimicrob Agents Chemother). We have helped investigate the potential for sensing AMR via volotile profiling (e.g. Smart et al., (2019) J Pharm Biomed Anal). We are also involved in a project led by Physicist Dr Massimo Antognozzi (University of Bristol) to develop novel sensors that can rapidly determine antimicrobial susceptibility in individual bacteria from clinical samples. This project was a recipient of the global Longitude Prize Discovery Award in 2017 and has spun out a company, Vitamica Ltd. 

We lead the One Health Selection and Transmission of Antimicrobial Resistance (OH-STAR) consortium. Working with ID and Micro Consultants at North Bristol and University Hospitals Bristol NHS Trusts, we are using whole genome sequencing to survey urinary E. coli and all Gram-negatives from bloodstream infection (e.g. Findlay et al., (2019) J Antimicrob Chemother). Our aims include monitoring ecological shifts resulting from local prescribing policy changes, and informing empiric prescribing and IV/oral switch for sepsis. In collaboration with a teams led by Prof Alastair Hay (Population Health Sciences) and Dr Kristen Reyher (Bristol Vet School), we aim to: (1) identify whether antibiotic usage reduction by GPs and on dairy farms reduces AMR prevalence in humans and cattle, respectively; (2) to define the environmental and management factors that influence acquisition and selection of AMR in dairy cattle and in dogs and (3) to identify whether AMR bacteria from these animals impacts on AMR in human infections

We lead the One Health Drivers of Antibacterial Resistance in Thailand (OH-DART) consortium. Working with colleagues at the Universities of Exeter and Bath, Mahidol University, Chulabhorn Research Institute and the NERC Center for Ecology and Hydrology, our consortium's aim is to define and prioritise the drivers of antibacterial drug resistance in humans in the community in Thailand taking a multi-disciplinary approach.

We also contribute to the FARMS-SAFE consortium led by Dr Kristen Reyher (Bristol Vet School) to work alongside colleagues at the University of La Plata to survey AMR and antimicrobial usage and identify the drivers of AMR in Argentinian farming systems.

As well as directing these core research activities, I lead the Bristol AMR interdisciplinary research network, funded by the Wellcome Trust, which aims to promote, facilitate and bring together AMR research from across the University of Bristol, reaching into all six of our faculties.

I lead the NERC funded "AMR in the real world" programme integration group, which aims to bring together and find synergy between all 13 research projects funded under the research council AMR theme 3 call.

I am PI and Academic Lead for the Medical Research Foundation-funded National PhD Training Programme in AMR Research, which will provide 31 fully-funded 4-year, interdisciplinary PhD studentships and will fund cohort building and knowledge exchange events for up to 175 additional PhD students working on AMR related projects from all disciplines and all U K institutions.
