• 339: Missing the Company of Elio

  TWiM pays tribute to Elio Schaechter, former TWiM host, blogger, and microbiologist extraordinaire, then reviews the finding that Archaea produce peptidoglycan hydrolases that kill bacteria - a form of competition. Hosts: Vincent Racaniello, Michael Schmidt, Michele Swanson and Petra Levin. Guest Mark O. Martin. Become a patron of TWiM.

• 337: Lifestyles of the Plasmids

  TWiM explains a study that examines pathogen presence in ancient humans and concludes that zoonoses emerged 6500 years ago with the domestication of livestock, and determination of universal rules that govern plasmid copy number. Hosts: Vincent Racaniello, Michael Schmidt, Michele Swanson, and Petra Levin Guests: Mark O. Martin Become a patron of TWiM.

• 336: The Volatilome of Biofluids

  TWiM explores the use of gas sensors and machine learning to identify microbes and antimicrobial resistance in clinical specimens, and how a harmful algal bloom species releases thiamin antivitamins to suppress competitors.   Become a patron of TWiM.   Links for this episode: Microbial and antimicrobial resistance diagnostics (Cell Biomaterials) Thiamin antivitamins suppress algal competitors (mBio) Music used on TWiM is composed and performed by Ronald Jenkees and used with permission.

• 335: Slip Slidin’ Away

  TWiM explains two strategies for bacterial competition for resources: by laying down a slippery lipid and pushing away competitors, or by breaking open cells with a spike, liberating essential nutrients.
