Figure 3From: Directed evolution and targeted mutagenesis to murinize listeria monocytogenes internalin A for enhanced infectivity in the murine oral infection modelInvasion of L. lactis expressing wild type or murinized InlA into Caco-2 (grey bars) or CT-26 (white bars) monolayers. Nisin induced L. lactis cells were invaded (MOI of 25:1) for 1 h before overlaying with gentamicin. Invasion was expressed as average cfu count (with standard deviation) or invasion relative to L. lactis plasmid only (below graph) (n = 3). The graph is representative of the data from three independent experiments.Back to article page
