TWiM explores the role of biofilms in infection by coronaviruses, and development of a Shigella vaccine using outer membrane vesicles derived from Salmonella.
The TWiM team reviews Salmonella colonization of three-dimensional miniature intestinal organs, and identification of a circadian clock in a non-photosynthetic prokaryote.
Vincent, Elio and Michael reveal the ASM COVID-19 summit, and how Salmonella injects a protein into the cell to drive suppression of the immune response.
The TWiM team reveals how ribosome modification resuscitates bacterial persister cells, and explain how a phage tail fiber protein exploits rotation of flagella to move towards the cell membrane.
The TwiModulators discuss aerosolization of bacteria and viruses in an ocean-atmosphere mesocosm, and how the common practice of decontaminating produce with chlorine produces viable but non-culturable pathogens.
The TWiM team reviews the microbiological safety of herbs in the United Kingdom, and how a peptide from the milkweed bug binds the ribosome and inhibits bacterial protein synthesis.
Vincent, Michael, and Michele discuss how iron might disperse bacterial biofilms in carotid arterial plaques, and controlling Salmonella by modulating host iron homeostasis.
Vincent, Elio, and Michele review how horizontal gene transfer from bacteria to an insect genome enables a tripartite nested mealybug symbiosis, and how probiotic bacteria work by competing for iron in the intestine.
On episode #27 of the podcast, Vincent, Elio, and Michael review how inflammation allows Salmonella to compete with fermenting gut microbes, and a riboswitch in bacterial and Archeal species that is triggered by fluoride.
On episode #4 of the podcast This Week in Microbiology, Vincent, Cliff, Margaret, and Michael review foodborne bacterial illness in the context of outbreaks associated with cantaloupes and Lebanon bologna.
