The motility of L. agilis toward mucin. Chemotaxis of L. agilis BKN88 attracted by mucin (a). Chemotaxis index designates relative cell numbers recovered from each capillary. The bar chart represents mean values (plus standard errors) of 5 independent assays. Translocation of the L. agilis strains through a simulated mucus layer (b). CFU of bacterial cells which passed through the simulated mucus layer was determined every 15 min. *P < 0.05
