Vincent, Elio and Michael discuss the stability of human coronaviruses on surfaces and in aerosols, and peptidoglycan production by a mosaic consisting of a bacterium within a bacterium within an insect.
Vincent, Elio, and Michael discuss a huge 30,000 year old virus recovered from Siberia, and nested symbiosis facilitated by horizontal gene transfer from bacteria to insect.
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 #17 of the podcast This Week in Microbiology, Vincent, Michael and Elio focus on endosymbiosis: the spread of Rickettsia in whitefiles, and a metabolic patchwork in nested symbionts of mealybugs.
