FIG 4 — Differential virulence analysis of K. pneumoniae CY814036, EC600, EC600-TC_a, and EC600-TC_b. (a) Serum resistance of the strains. Each test was repeated three times. Data are presented as the means ± SD. No significant difference (P > 0.05) was observed among EC600, EC600-TC_a, and EC600-TC_b. (b) Mouse infection model with an inoculum of 1.0 × 10⁷ CFU to depict the differential virulence of strains at 7 days. The survival curves of each group are significantly different (P < 0.0001). NS, normal saline.
