Start year: 2012

Summary: This project will develop a rapid diagnostic for detecting live bacteria based on membrane-disruptive toxins secreted by bacterial pathogens. The toxins will be detected from the resistance decrease they cause in a sealed lipid membrane. The diagnostic will have extensive application in triaging human carriers of pathogens, rapidly detecting bacterial contamination during surgical procedures and in managing food safety. Based on the same technology, we will also develop a tool to screen bacterial ion channels to identify compounds that disrupt the channel function and identify potential non-penicillin based antibiotics.
