Normally percolation theory is used to describe the movement of liquid through porous material. A good example of percolation is when hot water is forced through ground coffee in an espresso machine. By moving through the coffee via the empty spaces between the ground coffee particles, the water picks up the flavor of the coffee. Scientists now report in Nature that the spread of the bubonic plague bacteria in Central Asia by gerbils, works much the same way.
