Healthy female weaned piglets (Duroc × Landrace × Large white, weighing ≈ 8 kg) were randomly divided into four groups (5 per group). One group of healthy piglets received no treatment and served as a control. Piglets in the other three groups were intraperitoneally injected with 15 mL of E. coli ATCC25922 with an OD600 = 0.15, and 2 h later, they were given an intraperitoneal injection of saline, peptide HLFP-5 (2.5 mg/kg), or HLWP-4 (2.5 mg/kg), respectively, with an injection volume of 10 mL. After 12 h, all piglets were euthanized. The blood of all piglets was collected and the levels of inflammatory factors in serum were determined by the ELISA method. The inflammatory factor kit was purchased from Shanghai Hengyuan Biological Technology Co., Ltd. Partial livers, kidneys, spleens, and lungs of bacteria-infected piglets were collected for bacterial enumeration studies by standardized localization. Furthermore, some organ samples of piglets were stained with H&E for histological examination.
