TWiM investigates the high variability in the rate and amount of current production from microbial fuel cells, and how bacteria link their growth rate to external nutrient conditions via a protein that functions as a cellular rheostat.
TWiM reveals environmental integrons, bacterial genetic elements notorious for their role in spreading antibiotic resistance, and how Salmonella invasion is controlled by competition among intestinal chemical signals.
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.
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.
The TWiM team celebrates 100 episodes with a Talmudic question, and discussion of how a single mutation alters bacterial host tropism.
