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.
 
A video podcast by the American Society for Microbiology that highlights the latest in microbiology, life science and biotechnology news. ASM is composed of over 42,000 scientists and health professionals with the mission to advance the microbial sciences as a vehicle for understanding life processes and to apply and communicate this knowledge for the improvement of health and environmental and economic well-being worldwide.

The Guardians of the TWiV-o-verse discuss the process of codon deoptimization for the production of experimental infectious attenuated viral vaccines, and how a respiratory syncytial virus with 619 base changes was rescued by genomes with very large internal deletions. Hosts: Vincent Racaniello, Dickson Despommier, Rich Condit, Kathy Spindler, and …
 
Arturo Casadevall joins TWiV to discuss the use of convalescent plasma to treat COVID-19, including a history of the process, how plasma is prepared and tested, why it is difficult to conduct randomized clinical trials, how this treatment has fared and his hopes for the future. Hosts: Vincent Racaniello, Alan Dove, Rich Condit, and Brianne Barker G…
 
In COVID-19 clinical update #56, Daniel Griffin note increasing hospitalization in children and young adults, Pfizer vaccine efficacy results in 12-15 year olds, rapid self administered nucleic acid and antigen tests, mRNA vaccine efficacy in real world conditions, and improvement of long COVID after vaccination. Hosts: Daniel Griffin and Vincent R…
 
John, Monica, and Davida join TWiV to discuss development of a method to detect SARS-CoV-2 in raw sewage from all 14 of New York City’s treatment plants, and its use to determine the presence of the genome throughout the pandemic and detection of genome mutations from variants of concern. Hosts: Vincent Racaniello, Dickson Despommier, Rich Condit, …
 
Elio reveals his thoughts on the big themes of modern microbiology, followed by an analysis of the gut microbiome in patients with Parkinson’s disease. Become a patron of TWiM.

Alessandro Sette joins TWiV to discuss the role of T cells in COVID-19, the finding that amino acid changes in SARS-CoV-2 variants of concern have a negligible impact on T cell reactivity in convalescent patients and vaccinees, and whether a next generation vaccine should include more viral proteins than spike. Hosts: Vincent Racaniello, Alan Dove,…
 
In COVID-19 clinical update #55, Daniel Griffin reviews recommendations for keeping transmission low in school settings, optimal testing strategies for schools and businesses, impact of vaccines on asymptomatic infections, vaccine safety in PASC patients, and early use of aspirin associated with decreased mortality. Hosts: Daniel Griffin and Vincen…
 
Susan Weiss returns to TWiV to discuss coronavirus entry into cells and the role of spike protein cleavage by proteases, why lab escaped hypotheses for SARS-CoV-2 are unlikely, and modulation of innate immune responses during infection. Hosts: Vincent Racaniello, Rich Condit, Alan Dove, Brianne Barker, and Amy Rosenfeld Guest: Susan Weiss Subscribe…
 
In COVID-19 clinical update #54, Daniel Griffin covers effectiveness of 3 vs 6 ft physical distancing, effectiveness of masks, physical distancing, and eye shields, second vaccine dose completion, alleviation of COVID-19 symptoms after vaccination, vaccine trials in children, and IDSA approval of a mAb cocktail. Hosts: Daniel Griffin and Vincent Ra…
 
Forest and Maria-Isabel join TWiV to discuss their their project to engage thousands of citizens to swab inanimate surfaces in the San Diego area, then send the samples to the Rohwer Lab for nucleic acid analysis.

On a TWiV tetramer, we review the ongoing outbreaks of Ebolavirus disease in DRC and Guinea, evidence that SARS-CoV-2 infections in children are far more prevalent than are being detected, and recent long COVID estimates from the UK. Hosts: Vincent Racaniello, Rich Condit, Alan Dove, and Brianne Barker Subscribe (free): iTunes, Google Podcasts, RSS…
 
In COVID-19 clinical update #53, Daniel Griffin reviews underreporting of infections and long term disease in children, a blood test for T cells, results of phase 3 trials for monoclonal antibodies, preliminary findings on an oral antiviral, clinical trial of ivermectin, and recommendations for upcoming gatherings. Hosts: Daniel Griffin and Vincent…
 
To celebrate ten years, TWiM asks former hosts and guests to provide their thoughts on how microbiology has contributed to our understanding of the microbial world.
