Figure 3 Inhibition of F4-fimbriated ETEC adherence to IPEC-1 cells by L. amylovorus. The inhibition of F4-fimbriated ETEC adherence to IPEC-1 cells by the indicated L. amylovorus strains in exclusion (A), competition (B) and displacement assays (C) was tested with 3H-labeled ETEC cells as detailed in Methods. The means and standard deviations of 3–7 independent experiments are shown, each with three technical replicates.
