Fig. 2: Impact of aroA deletion on intracellular survival of S. agalactiae in macrophages.

A Phagocytosis rate of S. agalactiae strains by RAW264.7 macrophages, with intracellular bacteria quantified by CFU after 1 h infection and antibiotic treatment. B Intracellular survival of S. agalactiae in RAW264.7 macrophages at the indicated time points. Effects of aromatic amino acid supplementation on phagocytosis rate (C) and intracellular survival (D). Error bars represent SD. ***P < 0.001. Different lowercase letters indicate statistically significant differences between groups (P < 0.05).
