Cartoon outline for generating screens within a group of eight bacterial strains. The strains of interest are arrayed in a 96-well plate as shown in the top panel. These are then transferred to an agar plate as shown in the bottom panel yielding an array that includes each of the 28 possible interactions twice and each strain vs. itself once. A column to the right includes each strain by itself for comparison.
