New images reveal how antibiotics breach bacteria’s armor, boosting Thailand’s fight against drug-resistant infections
In a landmark observation that could reshape how doctors deploy last-resort antibiotics, researchers have captured, in real time, the moment a polymyxin antibiotic punctures the outer armor of harmful Gram-negative bacteria. The team used ultra-high-resolution imaging to show that the antibiotic rapidly creates surface bulges, prompting bacteria to churn out armor faster than it can shed it, and ultimately allowing the drug to infiltrate and kill the cell. Yet the breakthrough also reveals a critical caveat: the same antibiotics may be ineffective against dormant, non-replicating bacteria. This dual insight arrives at a moment when Thailand—and much of the world—faces persistent threats from drug-resistant infections that strain hospital resources and patient outcomes.
