From: Exploration of the role of the virulence factor ElrA during Enterococcus faecalis cell infection
Effect of ElrA-expressing E. faecalis on host cells. Exponentially growing E. faecalis strains were used to infect Raw264.7 macrophages and placental cells (Jeg-3), hepatic cells (HepG2), epithelial cervical (Hela) cells, fibroblastic kidney cells (ACHN), colonic epithelial cells (Caco-2), ileocecal epithelial cells (HCT-8), and epithelial kidney cells (A-704). Percentage of invasion was determined as the ratio of intracellular bacteria to the initial inoculum. Data are represented as mean with SEM of at least 3 independent experiments for each cell line. Statistical analysis was performed using unpaired Student’s t test. Asterisks indicate a p-value considered statistically significant (*P < 0.05; **P < 0.01; ***P < 0.001).
