Through the COVID-19 pandemic, genomic surveillance proved very important in serving to perceive the evolution and unfold of the SARS-CoV-2 virus. Now, a global group of researchers is asking for its potential to be harnessed to deal with antimicrobial resistance (AMR), a serious international problem that would in the end end in many extra deaths than the coronavirus pandemic.
AMR already causes substantial illness and loss of life worldwide, liable for roughly 1.27 million deaths in 2019. Some estimates recommend that by 2050, it may kill as many as 10 million individuals annually.
Professor Sharon Peacock on the College of Cambridge – the driving pressure behind the UK’s pioneering COVID-19 Genomics UK Consortium – stated: “Over the previous century, antibiotics have reworked our means to deal with an infection and sickness and cut back mortality. However micro organism have gotten more and more resistant, and with a restricted pipeline of recent antibiotics, we threat successfully returning to the pre-antibiotic period the place we are able to not deal with infections.
“When the world was hit by the COVID-19 pandemic, we confirmed how highly effective a device genomic surveillance may very well be in serving to us struggle again. This work grew out of its growing software to real-world issues comparable to detecting outbreaks in hospitals and locally – together with meals borne outbreaks. We now must take what we realized from the pandemic together with its daring and largescale use and reapply it to the complicated downside of AMR.”
The genome, which is ‘written’ in DNA or RNA, consists of a string of nucleotides. Every time a replica of the genome is made, errors can come up – for instance, one of many A, C, G and T nucleotides of DNA would possibly get swapped. These adjustments permit scientists to create lineages – household bushes – exhibiting how the genome has advanced and unfold. Within the case of SARS-CoV-2, they allowed scientists to establish sources of an infection, spot so-called ‘variants of concern’ and see whether or not public well being measures comparable to lockdown, journey restrictions and vaccination had been working.
The potential to enhance surveillance of AMR pathogens could also be even larger than for SARS-CoV-2 because the genome knowledge can detect and observe outbreaks, present a prediction for efficient antibiotic therapy, reveal the mechanism for resistance together with mutations and the acquisition of recent DNA, and assist perceive the motion of resistance mechanisms between micro organism.
Though surveillance of AMR micro organism is already utilized in some settings, the rising proof of its potential has largely not translated into routine use. Writing at the moment in The Lancet Microbe, a working group has set out how genomic surveillance may very well be utilized to the issue of AMR extra broadly, together with the obstacles that have to be overcome, presenting a collection of suggestions together with constructing capability, coaching of current and new workforces, standardising the best way that surveillance is finished to detect AMR, and agreeing equitable knowledge sharing and governance.
The group, which is funded by Wellcome, was initiated by Professor Peacock along side Wellcome SEDRIC (Surveillance and Epidemiology of Drug Resistance An infection Consortium) and delivered by a staff of practically 100 consultants co-led by Professor Kate Baker and Dr Elita Jauneikaite. 5 papers can be printed in the identical version of the journal, highlighting the breadth of assessment and evaluation undertaken by the staff.
The collection covers a number of areas for the appliance of genomic AMR surveillance together with in hospital settings to assist establish outbreaks and inform an infection prevention and management and informing scientific decision-making at a affected person degree. Additionally they spotlight purposes at a public well being degree to detect rising threats and to design and assess appropriate interventions like vaccination. It even has the potential to trace AMR pathogens transferring between people, animals, and the setting. The staff additionally thought-about future improvements in genomic surveillance of AMR, how the subsequent part of genomic applied sciences and evaluation strategies would possibly additional remodel the surveillance panorama.
Plenty of obstacles will first have to be overcome, nonetheless. These embrace an absence of assets and political will, and the necessity for extra coaching, notably round bioinformatics (the evaluation of genome knowledge). There are additionally sensible obstacles, together with in lots of nations a weak epidemiological surveillance and microbiology infrastructure, poor provide chains and pricing buildings, and points round efficient cooperation and knowledge sharing.
We’re on the cusp of realising the total potential for genomics in tackling AMR, however there’s nonetheless numerous work that must be performed. We want the scientific, public well being and political communities to work collectively to make this occur. AMR is an pressing downside. It isn’t one thing that can occur in years to come back – it’s occurring now.”

Dr Elita Jauneikaite, Imperial Faculty London, stated: “We’re going to be locked in an ongoing arms race with bacterial pathogens indefinitely. Genomic surveillance gives actual promise to assist us struggle again, offering invaluable data to restrict the unfold and influence of AMR.”
Professor Peacock added: “It was clear from the pandemic that sequencing was a significant device that was wanted in each nation worldwide. AMR is a worldwide downside and as soon as once more we want to verify nations worldwide are ready each to contribute to, and profit from genomic surveillance knowledge.”
Janet Midega, AMR Analysis Lead at Wellcome and SEDRIC Board member, stated: “Genomic analysis and surveillance are pivotal to detect pathogens and perceive the transmission and traits of drug resistance in each high- and low-income settings. With a view to reply successfully to this knowledge, we have to be sure that the instruments being developed are accessible and could be utilised by public well being companies around the globe.”
