Antimicrobial resistance has spread to London this month. The source of the outbreak? The Science Museum: its new exhibition, Superbugsexplores this monumental issue and our responses to it.

As Superbugs graphically shows, the inflammatory tone of the many headlines predicting an impending antibiotic apocalypse is not baseless. The evolution and spread of resistance among serious (and increasingly commonplace) bacterial infections continues to blunt much of our antibiotic arsenal, and make routine operations significantly more risky. Such infections now claim almost 700,000 lives annually, a figure that could rise to more than 10 million by 2050.

Superbugs isn’t out simply to scare, however. Much like Nature Microbiology, the journal I edit, the Science Museum aims to join the ‘resistance against resistance’ by shining a light on the problem’s scale, and the range of potential solutions.

The physical design of the installation aptly reflects aspects of the crisis. A vast illuminated wall dominates; set into it is a series of displays. This monolith, emblazoned with the show’s title, speaks of antibiotics’ barrier function — how they act as a great dam holding back a flood of infections. Standing in front of this cracked levee are 12 small towers into which have been set Petri dishes. Each contains a different type of (inactive) microbe, including MRSA and Neisseria gonorrhoeae — like outposts of resistance that have breached the barricade and now mingle among the crowds. It’s a powerful scene.

I was drawn irresistibly to the inset display cases. Combining text with striking visuals and interactive content, these take the visitor through medical history, from the discovery and introduction of antibiotics in the first half of the twentieth century, to the rise of resistance in the years following the introduction of each new drug, to ongoing efforts to revitalize our dwindling drug cabinet. Peppered through are personal testimonies. We meet doctors explaining why antibiotics are overprescribed; a nurse reminding of the fundamental importance of their work on infection control; designers who create products that enable no-touch use, or incorporate anti-bacterial materials, to reduce the risk of transmission.

Interviews with nurses, medics and others waging war on antibiotic resistance feature in the exhibition.

We hear a recording of bacteriologist and discoverer of penicillin Alexander Fleming, describing how microbes can become ‘educated’ to resist a drug. A culture of Penicillium mold grown from a stock of his original sample is shown nearby. A video describes the harrowing experience of Geoffrey Pattie, a cancer patient who during surgery contracted a strain of Klebsiella pneumoniae resistant to all current antibiotics. He spent five months in an isolation ward, and today lives with the life-altering effects of the infection, such as reduced mobility.

Nearly half of antibiotic use occurs in agriculture, to treat and prevent infection in livestock, but often also to promote growth. The drugs and bacterial resistance genes that they select for become widespread in terrestrial and marine environments, giving a large potential reservoir from which resistance can leap into clinically relevant pathogens. Inevitably, that is a serious problem for human health. The show reveals some of the technological fixes that are being investigated, including automated systems for monitoring livestock welfare to allow targeted interventions rather than treating an entire herd prophylactically. Also presented are possible alternative approaches to tackling infections, such as phages (viruses that kill bacteria) sourcing new antibiotic leads from oceans, soils and host-associated microbiomes in humans, komodo dragons and leafcutter ants.

The promise of such efforts is stirring. But finding a new antibiotic class that will make it to the clinic is “like searching for a needle in a field of haystacks”, cautions one researcher interviewed.

What isn’t covered in much depth is the parlous state of the antibiotic R&D pipeline. Many large pharmaceutical companies have closed their antibiotic development programmes in recent years. That includes Pfizer, the main sponsor of the exhibit — although the company did announce in 2016 that it planned to acquire AstraZeneca’s antibiotics division, and reinforced a strategic focus on tackling infectious diseases. The economics of antibiotic discovery and development is complicated: to bring a drug to market takes a massive investment in time and finances. Yet we will need these new drugs to be used ever more sparingly in future. So, under the current system, there is actually a disincentive for industry to put in the necessary investment – they would never break even, let alone see a return.

Superbugs is doubly timely. This week (13-19 November) is the World Health Organization’s World Antibiotics Awareness Week 2017, an opportunity to take stock of progress. Antibiotic resistance, until recent years a concern only of clinicians and microbiologists, is now globally recognised as a crisis through the work of key individuals, such as Britain’s chief medical officer Sally Davies, and reports from national and international bodies. In 2016 this culminated in the UN High-Level Meeting on Antimicrobial Resistance (see this Nature Microbiology editorial).The rise in academic research and conferences focused on antimicrobial resistance is a positive sign that new approaches can and will be found, despite the issues with the pharma marketplace and the ongoing hunger for antibiotics in agriculture and medicine.

But we remain a long way from winning what the Science Museum describes succinctly as the “fight for our lives”. Hopefully this polished, fact-packed exhibition will call many more to arms — from the lay visitor to the family doctor, local farmer and political representative.

Graphic window on a refugee scientist

3Q: Erik Nelson Rodriguez

Graphic artist Erik Nelson Rodriguez is an innovative comics journalist. With reporter Darryl Holliday, he began creating nonfiction stories in graphic-novel form at university, covering issues such as gun violence. In 2016, US National Public Radio (NPR) invited Rodriguez to collaborate on an account of Syrian refugee Nedal Said: a trained microbiologist and teacher, Said fled the war in 2013 and is now a researcher in Leipzig. The result, The Scientist Who Escaped Aleppois part of NPR’s special series on refugee scientists: a testament to the ordeals endured, and the extraordinary potential offered, by the refugee community.

What did you learn from working on this project?

I did not know much about the refugee crisis other than data I had researched for news graphics — statistics on people moving through the Mediterranean into Europe. Just seeing the astounding numbers trying to get away from war zones and how many did not make it past the sea affected me. But it wasn’t until I worked with NPR on Nedal Said’s story that I felt the full weight. To look, under a microscope, at the ordeal an individual has to go through to obtain a better life was a heavy lesson. I was shocked by the number of hurdles Nedal faced, whether escaping from detention or sleeping in parks in the frozen rain — and by how long he was away from his family as he travelled to find a new life for them. I also learned that there are programmes to help refugees trained in science. One is the Philipp Schwartz Initiative, a collective effort by Germany’s foreign office and other institutions named in honour of a Jewish scientist who fled Germany in 1933. I was pleased to find countries creating these opportunities for refugees to integrate after their harrowing journeys — especially when refugees are so happy to give back to that society.

How did you convey Said’s story visually?

NPR provided a timeline of Said’s travels from Turkey to the Balkans to Germany. It gave details about each location, along with interviews describing first-hand experiences. This formed the basis for the storyboard. It was important to me to show Nedal in his work and family life. He was described as always helping others through his scientific knowledge and skills as an educator, so we wanted to display him in those situations. We made sure that his family was highlighted: he was potentially sacrificing his life for them. I researched Aleppo during different periods to see what kind of destruction took place, and created panels featuring tanks, rifles, bullet-ravaged buildings. We re-edited the piece later to help things flow in a vertical comic strip. Aesthetically, I aimed to translate the grittiness and bleakness of the written material. I tried to convey the fear and dread of Said through his facial expressions. I used dark, somewhat sketchy lines to match the story’s tone, but kept a cartoonish quality as a subtle undertone. Working with the editors and researchers was really rewarding.

How can this kind of storytelling help refugees?

Seeing one individual’s journey to escape war and possible death will, I believe, help the public understand that these are just other people in very different circumstances. Having these stories told in detail with audio and visual representations will hopefully shed more light on how refugees struggle to escape the dark reality of their cities’ destruction. In particular, I hope that the public will understand better that without resources, people escaping war-torn countries do not have the opportunity to develop research, knowledge or a decent life, even if they are well educated. Yet the scientific community could gain from the experience and education of people such as Said, as they can provide original ideas developed thousands of miles away, adding fresh perspectives or processes. I hope visual storytelling can highlight these and other invisible parts of the world to show the public on the other side what they cannot see.
