Figure 11. Chitinases and chitin binding proteins do not influence growth of L. monocytogenes in Caco2 intestinal epithelial cells. Caco2 cells were grown on glass coverslips and infected with wild-type(WT), and chitinase/chitin binding protein deletion (ΔchiA, ΔchiB, Δlmo2467 and ΔchiA Δchib Δlmo2467) strains of L. monocytogenes. Extracellular bacteria were killed by adding gentamicin. At different time points coverslips were removed, host cells lysed and plated on LB agar media. The resulting number of CFUs of each strain for each time point has been plotted.
