What to know about Public Health Infrastructure

Researchers at Umeå University have developed a new class of compounds called TriPcides that target Staphylococcus aureus, including MRSA. These compounds are reported to disrupt infection processes and kill dormant persister cells, potentially offering a new strategy to combat antibiotic resistance.

What happened

TriPcides target MRSA, suppress infection and kill dormant bacteria to open a new front against antibiotic resistance Gaby Clark Scientific Editor Robert Egan Associate Editor In a new study, researchers show how so‑called TriPcides can target the bacterium…

Why it matters

The compounds disrupt the bacteria's ability to cause infection and can also kill dormant bacterial cells, which are often difficult to treat with existing antibiotics.

Common ground

The work is published in the journal Science Advances.
