This illustration released by the Centers for Disease Control depicts a three-dimensional (3D) computer-generated image of a group of carbapenem-resistant Enterobacteriaceae bacteria. The artistic recreation was based upon scanning electron micrographic imagery. A potentially deadly "superbug" resistant to antibiotics infected seven patients, including two who died, and more than 100 others were exposed at a Southern California hospital through contaminated medical instruments, UCLA reported Wednesday Feb. 18, 2015.
