Florey Institute Seminar Series (2018-19)
We are delighted to welcome Dr John Tregoning from Imperial Collage London who will give our next Florey Seminar.
Dr Tregoning has studied the immune responses to vaccination and respiratory infection for 15 years and has been an independent PI for 10 years. Based at the St Mary’s campus of Imperial College London, the Tregoning group’s research program is focussed on prevention of respiratory infections. This research has focused on vaccines to a range of respiratory pathogens. I have published over 50 articles in the area of immune responses to infection and vaccination. To achieve these aims, my group has developed a range of in vivo and in vitro models of infection and vaccination in early life, including RSV, Influenza, Pseudomonas aeruginosa, Staphylococcus aureus and non-typeable Haemophilus influenzae (ntHi). The research uses mechanistic studies in mice to identify correlates of protection that can be tested in human infection studies which in turn inform pre-clinical vaccine development studies.

Florey Institute Seminar Series (2018-19)
We are delighted to welcome Dr Despoina Marvridou from Imperial Collage London who will give our next Florey Seminar.
Bio
Dr Despoina Mavridou has a chemistry background and after finishing her undergraduate studies at the University of Athens, proceeded to do a PhD in Biochemistry at the University of Oxford working with Stuart Ferguson and Christina Redfield. Her project involved structure-to-function studies of Escherichia coli DsbD, a central protein for disulfide bond formation in the periplasm of Gram-negative bacteria. After her PhD, Despoina remained in the same research lab as a postdoctoral research associate continuing her work on disulfide bond formation, while she also branched out to study cytochrome c maturation in E. coli. In 2014 she was awarded an MRC Career Development Award to start her own research group at the MRC Centre of Molecular Bacteriology and Infection (CMBI) at Imperial College London. Before starting her fellowship, she spent a year as a research fellow in the Department of Zoology in Oxford, as part of the research groups of Kevin Foster and Stuart West. Her work there focused on the contribution of collective behaviour in bacterial competition.
As an independent group leader Despoina is broadly interested in the biology of Gram-negative bacteria and more specifically in processes that occur in the extra-cytoplasmic environment. Her research approaches span from the fundamental to the applied and her lab currently focuses on three main research directions: 1) Understanding the involvement of disulfide bond formation in mechanisms of virulence of key Gram-negative bacterial pathogens, like Pseudomonas aeruginosa and Klebsiella pneumoniae; 2) Investigating whether proteins involved in disulfide bond formation could be potential targets for the treatment of antibiotic-resistant bacteria; 3) Studying the dynamics of bacterial communities and more specifically the competitive interactions between toxin-producing enteric strains encountered in the gut microbiota.

Disulfide bond formation underpins antimicrobial resistance in Enterobacteria Wednesday 6th February 2019 1:00 pm F2, Firth Court |
Abstract
The disulfide bond formation (DSB) system has a central role in protein homeostasis by folding hundreds of proteins in the cell envelope of Gram-negative bacteria. Whilst the importance of this pathway for bacterial virulence is well-established, its contribution to antimicrobial resistance is unknown. Here, we report that DSB proteins are necessary for the function of key antimicrobial resistance determinants. Resistance arising from the production of β-lactamases, mobile colistin resistance enzymes and RND efflux pumps in Enterobacteriaceae is dependent on DsbA. Moreover, chemical inhibition of disulfide bond formation leads to sensitization of multidrug-resistant clinical isolates to existing antibiotic compounds. This makes the DSB system a promising antimicrobial resistance target, potentiating the use of existing drugs for the treatment of enteric pathogens.

Staphylococcal secrets of success: genomic perspectives of the rise of MRSA Tuesday 3rd July 2018 1:30 pm F2, Firth Court |
The widespread use of antibiotics, in association with high-density clinical care, has driven the emergence of multi drug-resistant pathogens that are adapted to survive and thrive in hospitalised patients and healthcare settings. Of particular concern are Methicillin-resistant Staphylococcus aureus (MRSA). Using whole genome sequencing we have been able build a picture of the evolutionary events that have shaped the genomes of successful hospital-associated MRSA clones, and trace their spread from the global level, right down to the patient level on a ward. In this talk I will focus on some of the most successful pandemic MRSA clones and illustrate how genomics has been used to gain a greater understanding of the epidemiology of disease, and what has driven the success of MRSA.

Stopping sooner: a safe way to reduce antibiotic overuse in hospitalised patients? Tuesday 1st May 2018 1:30 pm LT6, Hick’s Building |
Antibiotic overprescribing is driving antibiotic resistance in the NHS. Hospital doctors are told to ‘Start Smart then Focus’ but in reality the vast majority of antibiotic prescriptions started in hospital are continued to complete a ‘course’. Lack of evidence, lack of knowledge, prescriber behaviour and patient perceptions result in a ‘continue unless stop is justified’ approach. In my talk, I will present the work of the Antibiotic Review Kit (ARK) - Hospital project which aims to safely reduce antibiotic overuse by supporting a ‘stop of justify continue’ approach to antibiotic prescribing

Antibiotic resistance and the human microbiome Friday 23rd March 2018 1 pm F2, Firth Court |
Willem van Schaik is Professor of Microbiology and Infection in the Institute of Microbiology and Infection of the University of Birmingham. Professor Van Schaik obtained his PhD degree in microbiology from Wageningen University in the Netherlands. He then did post-doctoral studies on an EMBO Long-Term Fellowship at the Pasteur Institute (Paris, France). He then moved to the University Medical Center Utrecht in the Netherlands, where he set up his own research group on antibiotic resistance in 2010. Prof Van Schaik moved to the University of Birmingham in April 2017. He has received major grants from The Netherlands Organisation for Scientific Research, the Seventh Framework Programme of the European Commission, the Joint Programming Initiative on Antimicrobial Resistance (JPIAMR) and The Royal Society. He was awarded a Royal Society Research Merit Award in 2017.
The research group of Professor van Schaik combines experimental tools in molecular biology and biochemistry with the opportunities offered by the development of novel, high-throughput DNA sequencing technologies and bioinformatics to elucidate the mechanisms by which harmless commensals transition into multi-drug resistant opportunistic pathogens. In addition, he studies the role of complex microbial ecosystems, in particular the human gut microbiome, as reservoirs of antibiotic resistance genes (‘the resistome’).

Staphylococcus aureus Bacteraemia and the results of the ARREST trial Tuesday 6th February 2018 1pm LT3, Medical School |
"S. aureus is a common cause of severe community acquired and hospital acquired infection worldwide. Despite the associated mortality from this blood stream infection of nearly 20%, the optimal antibiotic treatment is uncertain and most treatment recommendations are based on observational studies and clinical experience. The ARREST study tested the hypothesis that adjunctive rifampicin would enhance early killing of S. aureus and reduce treatment failure or disease recurrence or death.
This large, multicentre, randomised, double-blind, placebo controlled clinical trial recruited adults from 29 UK hospitals with S. aureus bacteraemia. They were treated standard antibiotics with either additional rifampicin or placebo. The primary outcome was time to bacteriologically confirmed treatment failure, or recurrence or death from randomisation to 12 weeks.
I will discuss our experiences of running a clinical trial involving acutely ill patients in Sheffield and the results of the ARREST trial, including the implications for the management of patients with this serious infection."

Bio: I am a lecturer in the MRC Centre for Molecular Bacteriology and Infection and my research focuses on determining the molecular basis of persistent infection in Gram-positive bacterial pathogens. In this talk I will describe how S. aureus adapts to the host environment by acquiring mutations that shut down fast growth and/or toxin production, which enable it to survive immune attack and evade antibiotic therapy. I will also explain how our understanding of these processes has identified new therapeutic targets to prevent or eradicate persistent staphylococcal infections.

The theme of this years' event is "Think twice, seek advice" reminding people to never take antibiotics without first consulting a qualified healthcare professional. At this time of year, when everyone is full of a cold and wait times to see a GP are long, it can be more tempting than ever to take left over antibiotics. However, in the case of a cold, taking antibiotics will have no effect on the virus causing the infection and may cause unwanted side effects. The best thing you can do is give yourself time to get plenty of rest and consult a doctor if your symptoms persist. |
