Fig. 1From: Effects of Pseudomonas aeruginosa and Streptococcus mitis mixed infection on TLR4-mediated immune response in acute pneumonia mouse modelHE-stained lung tissues from wild-type acute lung infection mouse models. After the wild-type mice were infected with PAO1 (b), S. mitis (c), PAO1 + S. mitis (d), or PBS (a) for 48 h, mice were sacrificed and right lungs were stained with HE to observe histological changes.
