A New Game Plan - Wadsworth Center’s Dr. Jon Paczkowski Awarded $1.8 Million NIH Grant to Study Regulation of Virulence Factors
Current antibiotics work by interfering with bacterial growth, which is a fine game plan… until it stops working. More and more, bacteria are finding ways around this approach, resulting in a huge antibiotic resistance problem. Dr. Jon Paczkowski may just have come up with a new defensive strategy and recently received a five-year grant from the National Institutes of Health to investigate.
The award has already scored points, with findings published describing his strategy - not of interfering with growth, but rather the factors that bacteria use to communicate with each other to cause disease in humans.
