The TWiM team reveals an extremely low rate of mutation in a 2500 year old, 185 acre fungus in Michigan, and how a host-produced quorum sensing autoinducer controls the phage switch between lysis and lysogeny.
Dickson joins the TWiM team to discuss the nasal microbiota of dairy farmers, and attenuation of bacterial virulence by quorum sensing in the maize weevil.
From Indiana University, Vincent speaks with Ankur, Julia, and Xindan about their careers and their work on horizontal gene transfer, quorum sensing, and chromosome organization in bacteria.
Vincent, Elio and Michael discuss the finding of a prion in bacteria, and how communication between bacteria guides the decision between lysis and lysogeny.
The arrival in the US of plasmid-mediated resistance to colistin antibiotics, a last line of defense against many gram-negative bacilli, and a quorum sensing system in a eukaryote are topics of this episode hosted by Vincent, Michael, and Michele.
Vincent, Elio, Michael, and Michele review how microbial virulence can be increased as a consequence of community surveillance and adaptation to macrophages.
