On this episode, an electrochemical scaffold that delivers safe doses of hypochlorous acid to treat wound infections in humans, and a method for sampling and monitoring bacteria and viruses on surfaces using plain paper stickers.
TWiM explains how Vibrio biofilms are dispersed by polyamine signals, and the induction of inappetence by respiratory virus infection which causes alteration of the gut microbiome.
TWiM explores the use of a bacterial protein to make highly conductive microbial nanowires, and how modulin proteins seed the formation of amyloid, a key component of S. aureus biofilms.
TWiM reveals a potential mucus-busting weapon for patients with cystic fibrosis, and bacteria in the intestinal tract that can oxidize cholesterol, leading to lower levels of the lipid in blood.
Mark Martin joins Vincent and Michael to present compelling papers suitable for teaching microbiology to undergraduate students.
The TWiM team explores a stingless bee that requires a fungal steroid to pupate, and colonic biofilms containing tumorigenic bacteria in patients with colorectal polyps.
Vincent, Michael, and Michele explain the use of an electrochemical gradient to eliminate bacterial biofilms, and how phage susceptibility can be transferred by exchange of receptor proteins.
Jennifer joins Vincent, Elio, and Michael to talk about the work of her laboratory on how a respiratory virus enhances bacterial growth by dysregulating nutritional immunity.
Vincent and Elio marvel in the finding that a phage tail-like structure from a marine bacterium stimulates tubeworm metamorphosis, and reveal Ophidiomyces as a cause of snake fungal disease.
Vincent, Michael, and Michele discuss how iron might disperse bacterial biofilms in carotid arterial plaques, and controlling Salmonella by modulating host iron homeostasis.
