While antimicrobial resistance is a threat to all humanity, a tale of two worlds emerges, highlighting the heightened vulnerability of low- and middle-income countries. (Shutterstock)

Antimicrobial resistance now hits lower-income countries the hardest, but superbugs are a global threat we must all fight

The contrasting realities of antimicrobial resistance between high-income countries and low- and middle-income countries demands international co-operation to effectively fight superbugs.

Will we still have antibiotics in 50 years? We asked 7 global experts

We asked 7 global experts in microbiology and biochemistry if we are headed towards a future with no antimicrobial agents.

E. coli is one of the most widely studied organisms – and that may be a problem for both science and medicine

Researchers uncovered the foundations of biology by using E. coli as a model organism. But over-reliance on this microbe can lead to knowledge blind spots with implications for antibiotic resistance.
Antimicrobial resistance is now a leading cause of death worldwide due to drug-resistant infections, including drug-resistant strains of tuberculosis, pneumonia and Staph infections like the methicillin-resistant Staphylococcus aureus shown here. (NIAID, cropped from original)

Removing antimicrobial resistance from the WHO’s ‘pandemic treaty’ will leave humanity extremely vulnerable to future pandemics

Drug-resistant microbes are a serious threat for future pandemics, but the new draft of the WHO’s international pandemic agreement may not include provisions for antimicrobial resistance.

Wastewater is a valuable source of information – Africa’s scientists need to use it to find drug-resistant bacteria

Wastewater treatment plants receive wastewater from a variety of sources. This makes them useful proxies for determining the burden of antimicrobial resistance in communities.

Looming behind antibiotic resistance is another bacterial threat – antibiotic tolerance

Antibiotic resistance has contributed to millions of deaths worldwide. Research suggests that any bacteria can develop antibiotic tolerance, and possibly resistance, when pushed to their limits.
