The looming threat of antibiotic-resistant bacteria poses a significant risk to global health, with experts warning it could soon lead to a dramatic increase in deaths from infections. This alarming forecast is highlighted in recent research conducted by Northern Arizona University.
Published on December 26 in Communications Medicine, the study reveals a concerning trend in which bacteria are becoming increasingly resistant to multiple antibiotics. This growing resistance could potentially lead to a global health crisis, increasing the risk of infection-related fatalities worldwide.
Lead author Benjamin Koch, a senior research scientist at NAU’s Center for Ecosystem Science and Society (Ecoss), emphasized the seriousness of the situation, stating, “Multidrug-resistance is bad, but once a pathogen gains resistance to all known antibiotics, known as pan-resistance, a dramatically rapid shift, rather than a gradual rise in public health impacts, can be expected.” He warned that the problem could become exponentially worse than anticipated.
Research Insights
The research team, which included members from the Milken Institute School of Public Health at George Washington University and the University of Minnesota, modeled the potential impact of a hypothetical pan-resistant E. coli strain on sepsis mortality in the United States. Their findings indicated that sepsis deaths could rise by 18 to 46 times within five years if such a strain emerged.
While this particular strain has not yet developed, the rapid pace of bacterial evolution suggests it is only a matter of time. Predicting when pan-resistance might occur remains challenging, with estimates ranging from as soon as a year to as far off as a century.
Global Implications and Response
Antibiotic pan-resistance presents a unique challenge as it threatens populations across all income levels, erasing the healthcare advantages typically available in high-income countries. The potential for widespread fatalities from previously treatable infections underscores the urgency of addressing this issue.
Despite the grim outlook, there are actionable steps that governments, industries, and individuals can take to mitigate the risk. Strengthening regulations on antibiotic use in both healthcare and food-animal sectors, alongside incentivizing the development of new antibiotics, are crucial measures. Additionally, technologies that track the emergence and spread of antibiotic resistance could play a vital role.
On a personal level, Koch advises the responsible use of antibiotics, only as prescribed by healthcare professionals, and advocates for policies that enhance antibiotic stewardship and encourage the creation of new drugs. “We must reduce the forces that currently promote the evolution and dissemination of antibiotic-resistant pathogens,” the authors wrote, highlighting the importance of improved antibiotic management across various sectors.
