Resistant Bacteria Are Advancing Faster Than Antibiotics

"The proliferation of difficult-to-treat bacterial diseases represents a growing threat, according to the World Health Organization's (WHO) Global Antibiotic Resistance Surveillance Report. The report reveals that, between 2018 and 2023, antibiotic resistance increased by more than 40 percent in monitored pathogen-drug combinations, with an average annual increase of 5-15 percent. According to data reported by more than 100 countries to WHO's Global Antimicrobial Resistance and Use Surveillance System (GLASS), one in six laboratory-confirmed bacteria in 2023 proved resistant to antibiotic treatment, all related to various common diseases globally."

"For the first time, this edition of the report includes prevalence estimates of resistance to 22 antibiotics used to treat urinary tract, gastrointestinal, bloodstream, and gonorrheal conditions. The analysis focused on eight common pathogens: Acinetobacter spp, Escherichia coli, Klebsiella pneumoniae, Neisseria gonorrhoeae, non-typhoidal Salmonella spp, Shigella spp, Staphylococcus aureus, and Streptococcus pneumoniae."

"The results show that resistant gram-negative bacteria pose the greatest threat. Of particular note are Escherichia coli and Klebsiella pneumoniae, which are associated with bloodstream infections that can lead to sepsis, organ failure, and death. "More than 40 percent of E. coli and more than 55 percent of K. pneumoniae strains worldwide are now resistant to third-generation cephalosporins, the first-choice treatment for these types of infections," the report warns."

Antibiotic resistance increased by more than 40 percent in monitored pathogen–drug combinations from 2018 to 2023, with average annual increases of 5–15 percent. Data from over 100 countries indicate one in six laboratory-confirmed bacteria in 2023 were resistant to antibiotic treatment across common diseases. Prevalence estimates now cover resistance to 22 antibiotics used for urinary tract, gastrointestinal, bloodstream, and gonorrheal infections and focus on eight pathogens. Resistant gram-negative bacteria pose the greatest threat, especially Escherichia coli and Klebsiella pneumoniae, which show high resistance to third-generation cephalosporins. Salmonella and Acinetobacter are developing resistance to carbapenems and fluoroquinolones, reducing therapeutic options and driving reliance on expensive, last-resort antibiotics in low- and middle-income countries.
