9:45 – 10:00 Introduction by the Chair: “The wonderful world of bacteriophages”
Professor George Salmond, University of Cambridge, UK
10:00 – 10:30 The impact of bacteriophage on bacterial genome evolution
Dr Nick Thomson, The Wellcome Trust Sanger Institute, UK
Since the first bacterial whole genome sequence of Haemophilus influenzae was published in 1995 the rate of growth of genome sequencing has surpassed all predictions. The continued reduction in costs and new sequencing technology platforms being developed we can now contemplate not only sequencing a range of organisms which attempt to reflect the full diversity of bacterial genomes but to also go on to sequence multiple strains/pathotypes/geographically defined isolates, from the same species. Consequently, comparative genomics has come of age and has already revealed an increasingly varied number of strategies that have been employed by organisms during their evolution. However, within this diversity there are shared mechanisms of accretion and re-assortment of genetic determinants that have contributed in adaptation to differing lifestyles. Presented will be an overview of the impact that bacteriophage have had on the biology of enteric pathogens, focussing on the salmonellae.
10:30 – 11:00 STX-phages and virulence gene dissemination in pathogens
Dr. Heather E. Allison, School of Biological Sciences, University of Liverpool, UK
Since the first outbreak of E. coli O157:H7 there has been an explosion in the numbers and types of bacteria that are capable of producing Shiga toxin. The dissemination of Shigatoxigenic potential is mediated by bacteriophages (Stx phages) that are a diverse group of temperate phages defined only by carriage of the stx operon. We have characterised many of the factors that play a significant role in Stx phage infections including those that control host recognition and multiple infection events, as well as accessory virulence determinants that may contribute to a lysogen’s ability to survive in a complex microbial environment or colonise the gastrointestinal tract.

11:30 – 12:00 Bacteriophage abortive infection systems
Dr Peter Fineran, University of Cambridge, UK
Accumulating evidence demonstrates that viruses are the most abundant biological entities on the planet resulting in an obvious selective pressure for bacteria to acquire resistance to phage attack. Indeed, many mechanisms of phage resistance are known, ranging from bacterial cell surface alterations, through restriction and modification, to abortive infection. I will summarise these systems and describe a phage abortive infection resistance system in the economically important plant pathogen, Erwinia carotovora subsp atroseptica, the causative agent of the potato blackleg disease. This resistance system seems to work via a novel mechanism.
12:00 – 12:30 Novel anti-phage systems in bacteria
Professor Maggie Smith, Institute of Medical Sciences,University of Aberdeen, Scotland
Bacteria are under constant threat from infection by bacteriophages. As a consequence they have evolved a battery of defences against phage infection including restriction/modification systems, abortive infection systems and phage exclusion mechanisms. Recently some completely novel systems have been discovered such as Cas/CRISPR and phage growth limitation. It is obvious that these defence mechanisms have a profound effect on host range and therefore on the use of phage as therapeutic agents.
12:30 – 12:50 Tour of the BioPark
12:50 – 14:00 Lunch and Poster Viewing
14:00 – 14:30 Use of phages for detection of bacterial pathogens
Dr Catherine E.D. Rees, University of Nottingham, UK
Phage have a checkered history in terms of pathogen detection tests; many new assays have been heralded as the answer to rapid diagnostics, but few have lived up to these claims. This talk will provide an overview of phage methods for the detection of pathogens but will focus on those tests that have been commercially exploited, and on our own work using phage in combined assays to develop rapid tests for fastidious organisms.
14:30 – 15:00 Biotechnological challenges of phage therapy
Professor Mikael Skurnik, University of Helsinki, Finland
The challenges for successful launching of a profitable phage therapeutic product are discussed. These include intellectual property rights, safety issues, reproducibility, stability and robustness of the product. In optimal case a successful and marketable phage therapeutic product would be a highly purified bacteriophage preparation containing one or several fully characterized phages, accompanied by optimized methods of administration and backed up by properly controlled efficacy and safety studies.
15:00 – 15:25 Afternoon Tea/Coffee and Last Poster Viewing
15:25 – 15:55 Commercialisation of Phage
Dr Nick Housby, Chief Executive Officer, Novolytics Limited, UK
15:55 – 16:25 Immune responses following treatment with bacteriophage
Dr John B. March,Pentlands Science Park, Scotland
Our group has performed extensive studies using bacteriophages as DNA vaccine delivery vehicles. Although our interest is primarily in the immune response induced by the expressed vaccine antigen, we have also gathered extensive data covering the immune response to the bacteriophage proteins following exposure to the animal’s immune system. Phage have been delivered via a variety of different delivery routes- oral, intradermal, injection etc. The timelines and intensity of anti-phage responses observed, their impact upon bacteriophage titres following re-exposure to phage, together with implications for the treatment of bacterial infections by phage therapy will be discussed.
16:25 – 16:55 Does phage therapy actually work? Results from the first phase 2 clinical trial
Dr. David R. Harper, Biocontrol Limited, UK
Biocontrol has recently completed the first modern, regulated clinical trial of the efficacy of a bacteriophage therapeutic. The phase 1/2 trial targeted Pseudomonas aeruginosa ear infections and followed on from the successful veterinary field trial which was reported in 2004. Results from the recently completed trial will be reported, along with plans for future trials against other targets. These results will also be discussed in the wider context, as a proof of concept for the development of bacteriophage-based therapeutic agents for use in Western markets.
