New antimicrobial peptide combats drug resistant bacteria

Multidrug resistant bacteria that are hard to get rid of by antibiotics can be killed by a modified human peptide called SAAP-148. This peptide make the bacterial membrane leaky, even when they hide in a biofilm or are inactive.

In a collaborative study between the Leiden University Medical Center, the Amsterdam Medical Center, the University of Graz Leiden University, the NeCEN, and he Association of Dutch Burn Centre a paper is published that is important to combat drug-resistant bacteria and biofilms.
