Could better tests help reverse the rise of drug-resistant infections? Modeling study says yes in theory; now comes a reality check

A growing number of infections — such as pneumonia, gonorrhea and tuberculosis — are becoming harder to treat, as bacteria evolve defenses against antibiotics faster than we can develop new drugs to replace them. Duke University game theorist David McAdams says faster, more accurate tests for drug-resistant infections are being developed that could, at least […]

On-chip drug screening for identifying antibiotic interactions in eight hours

A KAIST research team developed a microfluidic-based drug screening chip that identifies synergistic interactions between two antibiotics in eight hours. This chip can be a cell-based drug screening platform for exploring critical pharmacological patterns of antibiotic interactions, along with potential applications in screening other cell-type agents and guidance for clinical therapies. Antibiotic susceptibility testing, which […]
