Agar spot overlay assays demonstrating broad-spectrum toxin production by four Bacteroides strains. The four toxin-producing strains are shown at the top and were cultured on plates overnight and removed, then the plates were overlaid with top agar containing the strains shown on the left to test for growth inhibition. A dark spot indicates growth inhibition of the overlaid strain. a Six Bacteroides and Parabacteroides strains used in the overlays. b The toxin-producing strains used in the overlays. c Non-Bacteroidetes gut strains from three different phyla used in the overlays
