Inhibition of S. aureus RF122 and NB305 adhesion to bMEC by L. casei CIRM-BIA 667. Shown are adhesion rates of S. aureus strains after 1 h of interaction with bMEC and following 2 h of preincubation of cells with L. casei at an ROI of 200:1 (white bars), 400:1 (gray bars), and 2,000:1 (hatched bars). S. aureus was used at an MOI of 100:1. An adhesion assay of S. aureus alone was used as a reference (black bars). Adhesion rates were then defined as the adhered S. aureus population in the presence of L. casei relative to the adhered S. aureus population in the reference experiment. Data are presented as means ± standard deviations. Each experiment was done in triplicate, and differences between groups were compared using Student's t test with Bonferroni's correction. ***, P < 0.0005.
