TWiM explores the use of Archaea to produce plastics from molasses wastewater, and a bacterial defense against bacteriophage infection that involves depletion of deoxynucleotides. Hosts: Vincent Racaniello, Michael Schmidt, and Michele Swanson Right click to…
TWiM reviews discovery of a bacterium that is visible to the naked eye, and reversible resistance to bacteriophage by shedding of the bacterial cell wall.
TWiM discusses citizen science surveillance of drug-resistant Aspergillus in garden soil, and the mechanism of action of a copper dependent antibiotic.
From ASM Microbe 2022 in Washington, DC, Heran joins TWiM to discuss her career and her work on the agent of tuberculosis, Mycobacterium tuberculosis. Hosts: Vincent Racaniello, Michael Schmidt, and Michele Swanson Guest: Heran Darwin…
TWiM explains how spindle-shaped Archaeal viruses evolved from rod-shaped ancestors to package a larger genome, and transcriptional recording by CRISPR acquisition from RNA.
TWiM explains the discovery of hotspots of genetic variation containing reservoirs of anti-phage systems in E. coli phages and their parasitic satellites, and pathogen desiccation tolerance promoted by hydrophilins.
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.
TWiM explains the use of lavender oil to disrupt Listeria biofilms, and how treatment of catheters with liquid silicone reduces associated urinary tract infections.
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.
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.
