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.

Editors in Conversation is the official podcast of the American Society for Microbiology Journals. Editors in Conversation features discussions between ASM Journals Editors, researchers and clinicians working on the most cutting edge issues in the microbial sciences. Topics include laboratory diagnosis and clinical treatment of infectious diseases, antimicrobial resistance, epidemiology of infections, multidrug-resistant organisms, pharmacology of antimicrobial agents, susceptibility testing ...
 
Revealing more about microbiologists, the work they do, and what makes them tick. We ask them what they're up to now and what's next? How is the science moving forward to solve some of the intractable problems of our times? What keeps them going in a tough, competitive field? What do they see for the future of research, education, and training? We hope to show you a glimpse of what scientists are really like and what's going on in cutting-edge research today.

Infections caused by multidrug-resistant Pseudomonas aeruginosa are considered a major public health problem. Antibiotic options are scarce but new drugs are emerging and more maybe available in the near future. Topics discussed: Pseudomonas aeruginosa as an important pathogen capable of developing resistance to multiple antibiotics Common mechanis…
 
TWiM reveals that the atypical antipsychotic quetiapine promotes multiple antibiotic resistance in E. coli, and treatment with Bifidobacterium lactis probiotic benefits patients with coronary artery disease. Become a patron of TWiM. Links for this episode: Antipsychotic promotes antimicrobial resistance (J Bact) Probiotic benefits patients with cor…
 
It is estimated that anywhere from 575,000 to 677,000 bloodstream infections occur annually in North America, with approximately 40,000 of those directly linked to patient mortality in the United States, making bloodstream infections the 11th most common cause of death in the US according to the Centers for Disease Control and Prevention. The detec…
 
Dr. Mallory Choudoir, microbial ecologist and evolutionary biologist at the University of Massachusetts Amherst shares how she leverages microbial culture collections to infer ecological and evolutionary responses to warming soil temperatures. She discusses complexities of the soil microbiome and microbial dispersal dynamics, and introduces fundame…
 
TWiM explains the use of lavender oil to disrupt Listeria biofilms, and how treatment of catheters with liquid silicone reduces associated urinary tract infections. Become a patron of TWiM. Links for this episode Lavender oil prevents biofilms (Lett Appl Micro) Silicone-infused catheters reduce infection (eLife) Viable but not culturable (TWiM 179)…
 
This episode is dedicated to the memory of the late George A. Jacoby, who was a pillar in the B-lactamase research community and a leader in the field of antimicrobial resistance. Assigning names to b-lactamase variants has been inconsistent and has led to confusion in the published literature. The common availability of whole genome sequencing has…
 
TWiM welcomes new host Petra, and explains how a small protein helps ensure that E. coli utilizes a preferred carbon source, and a screening strategy to identify inhibitors of the type IV secretion system that is essential for virulence of a variety of bacterial pathogens. Hosts: Vincent Racaniello, Michael Schmidt, Michele Swanson, and Petra Levin…
 
Antibiotic susceptibility testing is too slow. Faster identification of microorganisms is now common, as many laboratories use MALDI-TOF or molecular technologies for quick and definitive identification of bacteria. Improvements in susceptibility testing have lagged, as we continue to use tests that take a day for results, and which have not signif…
 
Mark returns to TWiM to join in a discussion of soil microbiota as game-changers in restoration of degraded lands, and discovery of a centimeter-long bacterium, the biggest yet discovered. Guest: Mark O. Martin Become a patron of TWiM. Links for this episode: Game-changing soil microbiota (Science) A World Without Soil by Jo Handlesman A World With…
 
Bacteriophages are interesting viruses that target bacteria and have been used for therapeutic purposes. Recently, the emergence of antibiotic resistance has spurred a renewed interest in using these viruses or their products as therapeutic tools against recalcitrant human pathogens. AAC has also published a recent manuscript from ARLG to guide the…
 
In this food-centric TWiM, we reveal the microbiomes of carnivorous vulture bees and of Gala apples from all over the world. Become a patron of TWiM.

When most of us hear the word ‘CAPA’, these days we more than likely immediately start thinking about SARS-CoV-2 variants, trying to remember how important this particular one was in the grand scheme of the COVID-19 pandemic. But, that is not the ‘kappa’ we will be talking about today. Instead, we’ll be discussing the other CAPA, or COVID-19 Associ…
 
Mark Martin returns to TWiM for a discussion of the frightening global burden of bacterial antibiotic resistance, and a solution to the problem of daylight nitrogen fixation in a cyanobacterium, despite the incompatibility of nitrogenase with oxygen produced during photosynthesis. Become a patron of TWiM. Links for this episode: Global bacterial an…
 
AAC just published a review from the WHO advisory panel on the antibacterial pipeline analyzing ‘traditional’ and ‘non-traditional’ antibacterial agents and modulators in clinical development current on 30 June 2021 with activity against the WHO priority pathogens, mycobacteria and Clostridioides difficile. Today, we will dissect this important pub…
 
In less than two months since it was discovered, the omicron variant of SARS-CoV-2 has become the dominant variant of the virus, causing an unprecedented rise in the number of cases of COVID-19 in the U.S. and elsewhere. The emergence of this variant has quickly led to some surprising claims about diagnostic testing for omicron and a renewed apprec…

As we round out yet another year of this pandemic, clinical microbiologists have not slowed down. We have not slowed down in our response to the pandemic or other day-to-day testing needs, despite the constant reagent backorders and personnel shortages, and equally as important, we have not slowed down in publishing high quality, informative and cl…
 
TWiM discusses antigenic variation within dengue virus serotypes, and an mRNA vaccine that induces antibodies against tick proteins and prevents transmission of the Lyme disease agent.

Infections caused by carbapenem-resistant Acinetobacter spp. are considered an urgent public health problem. Antibiotic options are scarce but new drugs may be available in the near future. We discuss this important topic with experts in the field. Topics discussed: Acinetobacter as an opportunistic pathogen Therapeutic approaches for Acinetobacter…
 
Is sequencing the SARS-CoV-2 genome useful for patient care? What about institutional infection control? And if clinical labs decide to perform SARS-CoV-2 sequencing, how should they do it? How should they report the results? And will they get paid? Until recently, sequencing of SARS-CoV-2 genomes has mainly been done in public health or research l…
