Quantitative scores for grading the severity of pneumonic lesions in lung parenchyma of Wistar rats. Scores of parenchymal lesions of the lungs in male (A) and female (B) Wistar rats infected by the K. pneumoniae ATCC 43816 doses (1.5 × 105, 1.5 × 106, 1.5 × 107 or 1.5 × 10.8 CFU/mL) on days 0, 5, 10 and 15 PI. All results were mean ± SD of six animals per group. Severity scores were analysed using Dunnett’s post-test (*: p < 0.05; **: p < 0.01; ***: p < 0.001); Days post-inoculation 5, 10 and 15 vs Day 0
