This Week in Microbiology

Vincent Racaniello

This Week in Microbiology is a podcast about unseen life on Earth hosted by Vincent Racaniello and friends. Following in the path of his successful shows "This Week in Virology" (TWiV) and "This Week in Parasitism" (TWiP), Racaniello and guests produce an informal yet informative conversation about microbes which is accessible to everyone, no matter what their science background.
