FIG 1

Identification of a third secreted diffusible antimicrobial molecule of B. fragilis 638R. (A) Agar overlay assays showing the ability of diffusible molecules from wild-type 638R or the double deletion mutant 638R Δbsap-1 Δubb (ΔΔ) to inhibit the growth of B. fragilis strains (strains used in overlays listed on the right). (B) Agar overlay showing a transposon mutant (tn) in background strain 638R Δbsap-1 Δubb that attenuates its antimicrobial activity against all three sensitive strains. (C) The transposon insertion site in BF638R_2714.
