This illustration depicts a 3D computer-generated image of a group of clindamycin-resistant GBS bacteria, which were arranged in chains. The artistic recreation was based upon scanning electron microscopic (SEM) imagery. If you look carefully, you’ll be able to see a number of these organisms undergoing the process of cell division along the long axis of their respective chains. Image credit: James Archer / CDC.
