Effects of the influenza virus, tryptophann and Lactobacillus on lung and intestinal tissue structure. (A) Histology analysis including H&E (scale: 100 μm) of the lungs, colon, and ileum was observed at 9 days post infection; (B) Spider web plot displaying histopathological scoring of lung damage; (C) Spider web plot displaying histopathological scoring of colon damage; (D) Spider web plot displaying histopathological scoring of ileum damage. Con: Female BALB/c mice aged 6 to 7 weeks (20 ± 2 g) were treated with PBS; Inf group: Female BALB/c mice aged 6 to 7 weeks (20 ± 2 g) were mice treated with influenza virus infection; Trp group: Female BALB/c mice aged 6 to 7 weeks (20 ± 2 g) were treated with exogenous tryptophan supplement; Lac group: Female BALB/c mice aged 6 to 7 weeks (20 ± 2 g) were treated with exogenous Lactobacillus supplement.
