Bacteria burdens and histopathology in pneumonia model of K. pneumoniae lung infection. Mice () were infected intratracheally with CFUs of strain YBQ, blood, and lung tissue were collected at 24 h, 48 h, and 72 h, respectively. (a) Bodyweight curve of mice was monitored for 7 days. (b) Bacterial burdens in the lungs and blood were counted on Luria-Bertani (LB) plates. (c) Lung sections were stained with hematoxylin-eosin, and histopathology of lung samples was evaluated (). Statistical analyses were performed by Student’s test. (), (), and () compared to each other.
