The cast of TWiM reveals how uropathogenic E. coli use a binding protein to treat copper as a nutrient or a toxin, and Antarctic soil bacteria that survive on trace atmospheric gases.

The TWiM team discusses the use of copper on exercise weights to reduce bacterial burden, and the mechanism of antigenic variation by which a fungus that causes severe pneumonia escapes the immune system.

On episode #1 of the podcast This Week in Microbiology, Vincent, Cliff, Michael, and Stan discuss transfer of DNA from a human host to a bacterial pathogen, and the ability of dry copper to kill bacteria on contact.
