	24 h	48h
P	(3.1 ± 0.4) × 10⁷	(1.2 ± 0.3) × 10⁸
P+AI-2	(5.6 ± 0.5) × 10^7∗	(3.2 ± 0.6) × 10^{8 ▲}
ΔP	(7.5 ± 0.38) × 10^6∗	(5.8 ± 0.5) × 10^{7 ▲}

P, PAO1 group; P+AI-2, PAO1+AI-2 group; ΔP, P. aeruginosa lasR rhlR mutant group; ΔP+AI-2, P. aeruginosa lasR rhlR mutant+AI-2 group. Asterisks denote a statistically significant difference from the PAO1 control group at 24 h (P < 0.05). Triangles denote a statistically significant difference from the PAO1 group at 48h (P < 0.05).
