Bacterial Biofilms Found to Quickly Clog Medical Devices

Pseudomonas aeruginosa bacteria (NIH)

Molecular biologists and engineers at Princeton University in New Jersey discovered that bacterial formations called biofilms can quickly tangle and trap other bacteria, disabling medical devices. The study by postdoctoral researcher Knut Drescher and colleagues appears online in a recent issue of Proceedings of the National Academy of Sciences . . . → Read More: Bacterial Biofilms Found to Quickly Clog Medical Devices
