Drug-resistant infections are outpacing treatments, and WHO says laboratory leaders are vital to protecting antibiotic effectiveness.
For laboratory leaders, the latest WHO report on antimicrobial resistance (AMR) underscores just how critical diagnostic testing, data accuracy, and surveillance capacity have become in the global fight against drug-resistant infections. With one in six bacterial infections now resistant to antibiotics, labs stand on the front lines. They are responsible not only for detecting resistant strains but also for generating the data that informs national and international response strategies.
According to a press release, the “Global antibiotic resistance surveillance report 2025”warns that between 2018 and 2023, “antibiotic resistance rose in over 40% of the pathogen-antibiotic combinations monitored,” with “an average annual increase of 5–15%.”
Data from over 100 countries reported to the WHO Global Antimicrobial Resistance and Use Surveillance System (GLASS) show that growing resistance to essential antibiotics “poses a growing threat to global health.” For the first time, the report presents “resistance prevalence estimates across 22 antibiotics used to treat infections of the urinary and gastrointestinal tracts, the bloodstream and those used to treat gonorrhea.” It examines eight common bacterial pathogens—Acinetobacter spp., Escherichia coli, Klebsiella pneumoniae, Neisseria gonorrhoeae, non-typhoidal Salmonella spp., Shigella spp., Staphylococcus aureus, and Streptococcus pneumoniae—each linked to these major infections.
Resistance Highest in South-East Asia and Eastern Mediterranean
WHO found that the “risk of antibiotic resistance varies across the world.” The highest resistance levels are in the WHO South-East Asian and Eastern Mediterranean Regions, “where 1 in 3 reported infections were resistant.” In the African Region, “1 in 5 infections was resistant.”
According to the report, resistance “is also more common and worsening in places where health systems lack capacity to diagnose or treat bacterial pathogens.”
“Antimicrobial resistance is outpacing advances in modern medicine, threatening the health of families worldwide,” said Tedros Adhanom Ghebreyesus, PhD, WHO director-general.
Tedros Adhanom Ghebreyesus, PhD, WHO director-general noted, “As countries strengthen their AMR surveillance systems, we must use antibiotics responsibly, and make sure everyone has access to the right medicines, quality-assured diagnostics, and vaccines. Our future also depends on strengthening systems to prevent, diagnose and treat infections and on innovating with next-generation antibiotics and rapid point-of-care molecular tests.” (Photo credit: WHO)
Gram-Negative Bacteria Present the Greatest Threat
The WHO report highlights that drug-resistant Gram-negative bacteria are becoming increasingly dangerous worldwide, with the heaviest impact seen in countries least equipped to manage the threat. Among these pathogens, E. coli and K. pneumoniae remain the most common causes of drug-resistant bloodstream infections—serious conditions that can lead to sepsis, organ failure, and death.
Globally, resistance to third-generation cephalosporins—the standard treatment for these infections—has climbed above 40% for E. coli and 55% for K. pneumoniae, and in parts of Africa, it exceeds 70%. Other essential antibiotics, including carbapenems and fluoroquinolones, are also losing effectiveness against E. coli, K. pneumoniae, Salmonella, and Acinetobacter. Once rare, carbapenem resistance is now emerging more frequently, reducing available treatment options and forcing reliance on last-resort antibiotics that are expensive, difficult to obtain, and often unavailable in low- and middle-income countries.
Progress in Surveillance but Major Gaps Remain
Despite these concerning trends, the report noted progress in global surveillance.
“Country participation in GLASS has increased over four-fold, from 25 countries in 2016 to 104 countries in 2023.” However, challenges persist: “48% of countries did not report data to GLASS in 2023,” and “about half of the reporting countries still lacked the systems to generate reliable data.” Many nations facing the highest burden of resistance “lacked the surveillance capacity to assess their antimicrobial resistance (AMR) situation.”
The report links its findings to the “political declaration on AMR adopted at the United Nations General Assembly in 2024,” which set global targets for combating antimicrobial resistance.
The declaration emphasizes strengthening health systems and working with a ‘One Health’ approach coordinating across human health, animal health, and environmental sectors.
WHO is calling on countries to strengthen laboratory systems and build reliable surveillance networks, particularly in underserved regions, to better guide treatment decisions and public health policies. The organization has set a goal for all nations to submit high-quality data on antimicrobial resistance and antibiotic use to the GLASS platform by 2030. Achieving this target will require coordinated efforts to improve data quality, expand geographic coverage, and enhance information sharing. WHO also encourages countries to implement comprehensive strategies to address antimicrobial resistance across all levels of healthcare and to ensure that treatment guidelines and essential medicines lists reflect local resistance trends.
The report is accompanied by expanded digital content available in the WHO’s GLASS dashboard, offering global and regional summaries, country profiles based on unadjusted surveillance coverage and AMR data, and detailed information on antimicrobial use.
With resistance trends worsening across regions, laboratory leaders are pivotal to turning the tide on AMR. Expanding diagnostic capabilities, improving data quality, and sharing timely resistance information will be key to shaping effective treatment guidelines and national policies. By advancing surveillance and stewardship from within the lab, clinical professionals can help preserve the power of antibiotics for future generations.
