Figure Lengend Snippet: Dose-dependent bactericidal activity of G31P–BPI 233 . (A) Heatmap summarizing the mean bactericidal rates against six reference strains and five clinical CRAB isolates. (B–E) Dose–response comparison of G31P–BPI 233 , a noncovalent G31P + BPI 233 mixture, BPI 233 alone, and G31P alone against clinical A. baumannii isolates 99391 (B), 99393 (C), and 99394 (D), and A. baumannii ATCC BAA-1605 (E). Component doses were molar-matched to the corresponding fusion-protein doses. Data are presented as mean ± SD.

Figure Lengend Snippet: G31P–BPI 233 protected mice against carbapenem-resistant Acinetobacter baumannii infection. (A) Survival of mice with lethal CRAB septicemia treated with saline (n = 15) or G31P–BPI 233 (n = 10). (B–G) Mice were intranasally challenged with A. baumannii ATCC BAA-1605 and treated with saline, G31P, BPI 233 , an equimolar G31P + BPI 233 mixture, G31P–BPI 233 , or colistin (n = 5 per group). Uninfected mice served as normal controls (n = 3). Samples were collected 24 h after infection. (B) Representative lung H&E staining; original magnification, 20×. (C) Lung injury scores. (D, E) IL-6 and TNF-α levels in bronchoalveolar lavage fluid. (F) Lung bacterial burden expressed as log10 CFU/g tissue. (G) Endotoxin activity in lung homogenates. Component doses were molar-matched to the corresponding fusion-protein dose. Data are presented as mean ± SEM. ns, not significant; * P < 0.05; ** P < 0.01; *** P < 0.001; **** P < 0.0001.

Figure Lengend Snippet: G31P–BPI 233 limits neutrophil-associated inflammation during CRAB pneumonia. Mice were intranasally infected with A. baumannii ATCC BAA-1605 and treated with saline, G31P, BPI 233 , an equimolar G31P + BPI 233 mixture, G31P–BPI 233 , or colistin (n = 5 per group). Uninfected mice served as normal controls (n = 3). Samples were collected 24 h after infection. (A–D) Representative flow-cytometry plots and quantification of CD45⁺CD11b⁺Ly6G⁺ neutrophils among lung (A, B) and peripheral blood (C, D) leukocytes. (E, F) Pulmonary levels of MPO and extracellular dsDNA. Component doses were molar-matched to the corresponding fusion-protein dose. Data are presented as mean ± SEM. ns, not significant; * P < 0.05; ** P < 0.01; *** P < 0.001; **** P < 0.0001.
