Congratulations to Sankalp who has received a £2300 International Research Collaboration Award from the University of Nottingham. Sankalp will spend two months (September and October) in Barth Smets’s laboratory at the Technical University of Denmark. This is a really fantastic opportunity for Sankalp to work in one of the leading environmental microbiology groups in the world. His work will focus on developing the iDynomics platform for individual based modelling of microbial interactions to model antimicrobial resistance. Well done Sankalp! And I look forward to visiting Barth’s lab too as part of the project.
Sankalp and I have just returned from a weekend trip to Santa Fe for the Viral Dynamics conference in honour of Alan Perelson’s 70th birthday.
The conference itself was very high quality – excellent talks throughout from some extremely eminent people in virus research. I particularly appreciated David Ho’s opening talk and Alan Perelson’s closing keynote; David’s talk on HIV dynamics reminding me just how good Alan and Avidan Neumann’s modelling contribution was: it wasn’t about developing big complex models, or doing very fancy mathematics; it was about doing the right simple model to make the most use of the data. Alan’s talk focussed on his earlier work in theoretical immunology – very many interesting examples showing how much you can learn by thinking in mathematical/computational ways.
The best part of the conference was meeting up with people – whether old friends from the short time I spent in LANL (Alan, Jack) and my PhD days (Ruy, Sebastian) – or brilliant people I hadn’t met before with whom I had some very stimulating conversations.
What was also evident was the warmth felt by so many people towards Alan. I only spent 3 months in the lab in 1994 – in between my degree and PhD – and went back for another month in the summer of 1995 – and yet when Ruy Ribeiro sent the invitation I immediately felt that this was a meeting I couldn’t miss. Many people there had collaborated with Alan for many years. And while Alan’s contribution to science is enormous, the plaque that the organizers made for him was for friendship, collaboration and mentorship, with a network graph of his collaborative research outputs. In this, Alan is a positive example for us all.
We went with a poster:
which was Sankalp’s first conference poster presentation! I thought that this would be a good opportunity for him; although Sankalp’s model is about bacteriophage in the context of AMR, while the conference focussed on human disease viruses, the conference attendees mainly worked in mathematical models of virus dynamics. This meant that Sankalp was among people who understood what he was doing and why he was doing it, speaking the same language. Sankalp was busy – he had people speaking with him for the full 2 hours of the poster session – and we received many interesting ideas and suggestions from these conversations.
Last month the review that Sankalp and I contributed to was published on line by Advances in Microbial Physiology. This review was led by Jon Hobman, with considerable writing by Chandan Pal. It is a real honour to have co-authored with the amazing Joakim Larsson. My own contribution was small: Sankalp contributed some review material on modelling, and I got stuck in with Joakim and Jon in the editing phase to ensure we had a coherent story. Overall, this is a very nice and timely review, and we have had a lot of interest in it already. Citation and abstract:
Pal C, Asiani K, Arya S, Rensing C, Stekel DJ, Larsson DGJ and Hobman JL 2017. Metal Resistance and Its Association With Antibiotic Resistance. Advances in Microbial Physiology. DOI: https://doi.org/10.1016/bs.ampbs.2017.02.001.
Antibiotic resistance is recognised as a major global threat to public health by the World Health Organization. Currently, several hundred thousand deaths yearly can be attributed to infections with antibiotic-resistant bacteria. The major driver for the development of antibiotic resistance is considered to be the use, misuse and overuse of antibiotics in humans and animals. Nonantibiotic compounds, such as antibacterial biocides and metals, may also contribute to the promotion of antibiotic resistance through co-selection. This may occur when resistance genes to both antibiotics and metals/biocides are co-located together in the same cell (co-resistance), or a single resistance mechanism (e.g. an efflux pump) confers resistance to both antibiotics and biocides/metals (cross-resistance), leading to co-selection of bacterial strains, or mobile genetic elements that they carry. Here, we review antimicrobial metal resistance in the context of the antibiotic resistance problem, discuss co-selection, and highlight critical knowledge gaps in our understanding.
Today I have made a new publication foray and submitted a manuscript to bioRxiv. This is the main paper to have come out of work on our BBSRC Lux grant. We are yet to find a peer-review home – but one of our co-authors has already had a conversation with someone who wants to use the method – so it was time to put the manuscript out there while we continue with the peer-review process. R code and Biomodels submission will follow. The manuscript details are:
Congratulations to both Hannah Williams and Laurence Shaw who have both now left the lab (after short positions) to new roles. Hannah is now working at Public Health England as a mathematical modeller. Laurence is now working for Nottingham Trent University as a lecturer in statistics. Wishing both Hannah and Laurence all the best in what I am sure will be fabulous careers. Both are on fixed term contracts so if you are reading this and looking to recruit an excellent mathematician/statistician then both Hannah and Laurence have my highest recommendation!
Last night I had the enormous privilege of being on a panel following Lord Jim O’Neill’s lecture on AMR as part of the University of Nottingham’s Chancellor’s Lecture series.
It was a real coup for the university to have Jim O’Neill speak. It was a great event – well attended by alumni and many other’s. The lecture was brilliant: O’Neill is a very engaging speaker and spoke with confidence and passion on the findings of his report. He mainly focussed on the ten point plan:
It was especially interesting seeing AMR from the perspective of an economist: not just in quantifying the problem in monetary terms (his argument that $40B spend will save $100T costs is compelling) but also how he breaks down the solutions into ‘supply’ and ‘demand’ side solutions and especially his emphasis on the importance of reducing demand for antibiotics through 6 of his points. (I’m not sure where our emphasis on waste management fits into that – but that is another matter – and actually having an economist (Steve Ramsden) on our project also helps framing it).
Professor Liz Sockett kindly asked me to serve on the panel (along side Dr Mat Diggle from EmPath) – this was a new experience for me – I was a little nervous – but the questions were good and interesting. The first couple of questions were more clinically focussed and answered by Liz and Mat. A question came up about how we prevent rapid spread of resistance to any new antibiotics we might discover. Mat gave a good answer from a clinical perspective, and I was able to add that there would need to be very wise use (if at all) of any new clinically important antibiotics in veterinary use. (To be fair, that point is made in the O’Neill report anyway!) And then got a question direct to me about agricultural waste management practises in developing countries. This was a nice one – as I have recently visited China and then had visitors from South Africa. So I was able to speak about the challenges of AMR from pig farming in China – the Chinese government are very committed to environmental research and China has a very well-funded research programme; South Africa is also very interesting because there is a mix of modern farming where the challenge of reducing antibiotic use is similar to in the UK, and then traditional subsistence farming, where nutrition is the biggest challenge, and the antibiotic challenge is more about access to antibiotics rather than use reduction.
After the talk, many interesting people came to speak with me, which was really nice, while Professor Christine Dodd looked after our stand and she also received many questions.
