Professor Helen Blackwell and Colleagues Identify Chemicals That Interrupt A. baumannii Quorum Sensing

Professor Helen Blackwell's work with A. baumanni, a microbial pathogen, recently has been featured in the news. Once these bacteria gather together and reach a critical mass, they form biofilms that can coat medical equipment such as catheters and breathing tubes. Dr. Blackwell and her colleagues recently published an online-first article, "Attenuation of Quorum Sensing in the Pathogen Acinetobacter baumannii Using Non-native N-Acyl Homoserine Lactones," for ACS Chemical Biology that examines how certain small molecule chemicals can interrupt A. baumanni's chemical signaling; this interruption precludes the microbe from forming biofilms. The group's work holds great promise for the many individuals who die from infections caused by the microbe.
