Efficacy of peptides in the K. pneumoniae-induced pneumonia mice model. The number of K. pneumoniae CFU in the BALF was calculated from the number of colonies growing on MHA plates (A). Effects of Nigrocin-PN and derivates on lung inflammation caused by K. pneumoniae were indicated by wet/dry ratio (B). The right middle lobe was further fixed and stained with haematoxylin and eosin, the magnification is 20 × , and the bar length represents 100 µm (C). ####P < 0.0001 versus the drug-free control group (PBS); NS means not statistically significant
