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.
Corkscrewing through snot
The TWiM team reviews Salmonella colonization of three-dimensional miniature intestinal organs, and identification of a circadian clock in a non-photosynthetic prokaryote.

Antivirals made by bacteria
The TWiM team reviews the movie Jezebel, played against the background of the yellow fever epidemic of 1853 in New Orleans, and prokaryotic viperins, ancestors of the eukaryotic enzymes that synthesize antiviral molecules.
TWiM explores the use of a bacterial protein to make highly conductive microbial nanowires, and how modulin proteins seed the formation of amyloid, a key component of S. aureus biofilms.

It’s a microbe-eat-microbe world
Mark Martin returns to TWiM for a discussion of a predatory bacterium appropriately named Vampirococcus lugosii, and Elio reveals how bacteria can be used on the International Space Station to efficiently extract rare earth elements in microgravity.
Ancient bacterial DNA
In this episode of TWiM, control of Campylobacter in raw chicken by zinc oxide nanoparticles in packaging material, and Salmonella enterica genomes from a16th century epidemic in Mexico.
Dirt is not simple
In this episode of TWiM, the hidden biochemical diversity in soil-dwelling Actinobacteria that could lead to a second Golden Era of antibiotic discovery, and structures of glideosome components reveals the mechanism of gliding in apicomplexan parasites.
