In this episode we speak with Tristan Ferry, one of the main drivers of Phage Therapy in France. We talk about how phage therapy is managed in France, we focus on how phages are used against implant associated infections, what are the pathogens involved and what is the best administration route, what they look for in phages and failed treatments and learnings.

On the personal side we could hear a more personal view of his work, how it is to manage such responsibilities, financial pressures of the scientific system and one of the best pieces of advice for PhD students.

22.- Expert opinion on phage therapy | Round table from the First International Symposium on Advances in Phage Therapeutics

We are sharing one of the sessions of the 1st International Symposium on Advances in Phage Therapeutics that was held in Braga, Portugal during the month of June. You will hear a round table focused in challenge and frontiers for phage therapy.Martin Loessner from ETH Zúrich, moderating the discussion with Rob Lavigne, from KU leuven, Jean Paul Pirnay and Sara Djebara from Queen Astrid Military Hospital and Mzia Kutateladze from Eliava Phage Therapy Center.

Topics such as: clinical improvement vs bacterial eradication, phage and antibiotic combination or resensitation, is it more important to have 2-3 really good phages or a big collection that you can go to?, can we move from a simplistic reductionist to a systems, more complex view?, what is the advantage of using phage mixtures?, is AI the way forward?, what should be the future of phage therapy?, is phage resistance necessarily a bad thing, if used long-term?,should there be last-resort phages?, do we need to train phages?, What about engineering bacteriophages? These and much more in this hour of conversation packed with food for thought! Enjoy!

Science is a road of failure, however those failures can also bring lessons. In this episode we re-visit the best answers to one of our career questions: Was there any failure that set you up for future success? Do you have a favourite failure?

You can hear phage researchers explaining what failure means for them in many different contexts (Paul Bollyky, Yves briers, Luis Melo, Colin Hill, Evelien Adriaenssens, Paul Turner, Lorenzo Corsini and Rob Lavigne).

This episode is one of our ways to celebrate our 2 year anniversary and to thank you for your support over this time.

We talked about his experience using phages as biotechnological tools: engineering phage RBPs and whole phage particles for detection of highly pathogenic bacteria of interest in the army, such as Bacillus anthracis, Yersinia pestis and Klebsiella pneumoniae.

You can hear about the detection tools and their challenges to identify Bacillus anthracis, and how they compare to phages. You will learn how they developed diagnostic phage proteins, a clever assay for antibiotic sensitivity testing and how they developed diagnostic phages.

We also touch briefly on phage engineering and one of the challenges they faced, and how they solved it.
