Vincent, Elio, Jo, and Michele review evidence for bacterial DNA integrated into the human genome, and control of the symbiont population in an insect midgut.
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.
