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.

Hosts: Vincent Racaniello, Michele Swanson and Michael Schmidt Guests: Deanna Beatty, Mark Hay, Gina Lewin, Frank Stewart, and Marvin Whiteley At Georgia Tech, members and trainees of the Center for Microbial Dynamics and Infection discuss the identification of pathogen essential genes during coinfections, and how coral management can improve coral defenses against pathogens. Become a patron of TWiM.
