Overview: Our team focuses on the functional and structural characterisation of tripartite efflux pumps, as well as on the wider structure of outer membrane in Gram-negative bacteria, with regards to antibiotic permeability and by proxy resistance. To that end we utilise a multidisciplinary integrative approach combining in vivo genetic and functional assays with in vitro biophysical and structural techniques including X-ray crystallography, surface plasmon resonance (SPR) and structural mass-spectrometry. We also use molecular modelling approaches to analyse potential drug-antibiotic docking interactions.

Where are you looking for antibiotics: We are investigating the potential antimicrobial properties of compounds that bind to efflux pumps or interfere with their assembly. We are also interested in efflux pump inhibitors (EPIs) which can augment the action of available antibiotics. We combine in silico drug design and docking with chemical library screening to identify compounds.
Expertise required: We are always happy to collaborate on functional characterisation of novel protein pumps and pump components. We are looking for complementary structural platforms to our own facilities and expertise, which may include e.g. NMR and cryo-EM facility access.

Dr Jonathan Cox
Lecturer in Microbiology, Aston University
School of Life and Health Sciences, Aston University, Aston Triangle, Birmingham, UK B4 7ET.
Overview: I lead the Mycobacterial Research Group at Aston University. We are a team composed of 3 PhD Students and a Post Doctoral Research Fellow with the objective of improving the understanding of the physiology of mycobacterial pathogens such as Mycobacterium tuberculosis. Our aim is to discover and develop new antibiotics for the treatment of mycobacterial diseases that can circumvent current antibiotic resistance mechanisms.
Specific targets: We exclusively work on mycobacteria. In addition to tuberculosis, we have recently been working closely with clinicians at Birmingham Children’s Hospital on an aggressive pathogen called Mycobacterium abscessus that infects children and young adults with cystic fibrosis. This infection is becoming increasingly difficult to treat, so we are engaged with developing new treatment regimes to overcome resistance mechanisms in this organism.
Where are you looking for antibiotics: We collaborate with medicinal chemists at University of Hertfordshire, University of Bradford and at Aston University. We are engaged in drug repurposing and natural product drug discovery.
Expertise required: My team are always on the hunt for new chemical space that has the potential for antimicrobial activity. We are specialists in identifying the mechanism of action of antimicrobials, and this information helps to discover new drug targets and refine the inhibitory chemicals into druggable antibiotics.
Expertise offered: Mechanistic knowledge of microbial physiology, resistance mechanisms and drug discovery.
Keywords: Mycobacteria, antibiotic drug discovery, microbial physiology, mechanism of action.
Professor of Microbiology, Ulster University
School of Biomedical Sciences, Ulster University, Coleraine, Northern Ireland. BT52 1SA.
Overview: We are interested in how environmental pressures influence the spread of antibiotic resistance by horizontal gene transfer. We have been working a lot with filter feeding organisms and have shown that freshwater sponges, Daphnia, and various mussels all facilitate transfer of vancomycin resistance in members of the genus Enterococcus. We believe that by understanding the mechanisms at work here we can develop ways to slow down the inexorable spread of resistance and, ultimately, protect the next generations of antibiotics. In the course of our work, we have identified some antibacterial activities among the filter feeding organisms that may have the potential for exploitation. In addition, we have been looking at the conjugation mechanisms employed by the enterococci using whole genome sequencing approaches, and we believe it may be possible to harness some of the signalling systems as antibacterial agents.
Specific targets: Currently we are mostly focused on Gram-positive bacteria, but we have an interest, and direct expertise, in bacterial communication systems across both Gram-positive and Gram-negative species. At present, our group works with Enterococcus spp., Pseudomonas aeruginosa, Clostridium difficile, Salmonella spp. and Campylobacter spp.
Where are you looking for antibiotics: We have two approaches to searching for new antibiotics.
(A) We are looking for antimicrobial activity in freshwater and marine filter feeding organisms. We are testing extracts for activity against a range of antibiotic resistant bacteria.
(B) We believe that disruption of communication offers a realistic opportunity to:
1. Develop narrow spectrum agents and
2. Develop agents that should not generate excessive selective pressure to promote resistance. Therefore, we are also focused heavily on the antibiotic resistant bacteria themselves and are trying to dissect their communication systems at the molecular level.
Expertise required: The primary goal of participating in the network for us would be to gain access to open minded collaborators. We have no specific technique or enterprise in mind. We need help with everything! We currently work with a few multidisciplinary projects involving engineers, public health professionals and nutritional biochemists and we see the value of such an approach in generating new ideas.
Expertise offered: We can offer a range of microbiological assays, including biofilm cultivation, cultivation of anaerobes and microaerophiles, electron microscopy, whole genome sequencing.
Bottlenecks: Access to expertise that we currently do not have in the form of meaningful collaborations. We are concerned, however, that collaboration may be hindered by the desire of institutions and investigators to protect their intellectual property. Clearly this is necessary, but it is something that needs to be addressed at the outset in a new collaborative network.
Keywords: Bacterial communication, horizontal gene transfer, quorum sensing, antimicrobial peptides, environmental resistance reservoirs.
Biomedical Sciences, Ulster University, Cromore Road, Coleraine BT52 1SA, Northern Ireland.
Overview: My research group’s work is centralised around biosurfactants, focusing on the production of microbial biosurfactants, their biosynthesis and their biotechnological and industrial applications, especially in environmental, medical, pharmaceutical and health related areas.
Specific targets: Biosurfactants are produced by various bacterial, yeast and fungal species. My research is focusing on a range of Gram-positive and Gram-negative bacteria associated with skin infections and wounds.
Where are you looking for antibiotics: I have tested the antibacterial properties of two well established biosurfactants; mannosylerythritol lipids (MELs) and rhamnolipids which are produced naturally. They have shown activity against Gram-negative bacteria, and when combined with antibiotics, they have demonstrated some activity against Gram-positive bacteria.
Expertise required: I am currently identifying the mechanism of action of the biosurfactants on bacterial cells using scanning electron microscopy. In the future, I want to use molecular biology to explore and elucidate this further. I would love to learn more about this and possibly make connections with other researchers who have focused their research on this. I would also like to meet other researchers with in vivo experience and drug formulation experience to enhance my research further by developing an effective combination topical antibiotic/biosurfactant treatment to test on laboratory animal models.
Expertise offered: With a wide range of skills and expertise I can assist in the development of new ideas and trouble shoot problems that may arise. I am extremely resilient in my career, and this is something I can lend to others through sharing my experiences. I have a wide range of scientific skills such microbiological testing, small scale and large scale fermentation skills and in vitro assay experience both on bacteria and human keratinocyte skin cells.
Bottlenecks: Current literature focuses on optimising the production of biosurfactants and understanding their biosynthesis. My works relates to their application as a combination therapy with antibiotics and this novel work branches across many specialisms, from biotechnology to AMR to industry. Due to this, it can be difficult to portray the impact of my research as each specialism is interested in different aspects of my research. Attending the ABX networking event will give me the possibility to bridge the gaps between the specialisms.
Keywords: AMR, biotechnology, microbiology, biosurfactants, combination therapy.

University of Birmingham
School of Biosciences, University of Birmingham, Edgbaston, Birmingham, B15 2TT.
Overview: My main driver is bridging the gap between different disciplines for the design of analysis pipelines and the biological interpretation of the results. My specific research objectives are: 1. Alternatives to the use of antibiotics 2. Understanding of antibiotic resistance (AR) from a metabolic network and evolution point of view 3. Identification and characterization of microbiomes with relevant pathogenic traits. To accomplish these objectives, I use high-throughput data (DNA, RNA, metabolites) and metabolic/regulatory modelling methods. I use genome scale metabolic and regulatory modelling to better guide hypothesis testing in the laboratory to understand metabolic network rewiring leading to AR, thus finding complex genotype-phenotype associations. High-throughput sequencing data is analysed with metagenomic approaches for characterization of different natural and clinical environments.
Specific targets: I have both specific targets and general microbiome targets. For the computational modelling, my target is Pseudomonas aeruginosa and Clostridium difficile. And for the microbiomes, I aim to focus on characterizing the environmental role of not only bacteria, but also of phages.
Where are you looking for antibiotics: Environmental organisms (mined from the microbiomes).
Expertise required: Experimental validation of my computational predictions/hypotheses. Since my laboratory is (so far) only computational based, I rely on collaborators for the wet-lab work.
