Soluble plantain NSP inhibits adhesion of S. Typhimurium to the porcine B1OXI enterocyte cell-line in vitro.

Pre-treatment (30 min) with soluble plantain NSP, dose-dependently blocked adhesion of (A) S. Typhimurium LT2 and (B) S. Typhimurium 4/74 to B1OXI cells (N = 3 experiments, each with n = 4 replicates); * PPPC) S. Typhimurium LT2 and (D) S. Typhimurium 4/74 into B1OXI cells was also blocked by plantain NSP. Data (mean ± SEM) expressed relative to adherence (or invasion) of vehicle-treated control (100%). Light microscopy of Giemsa-stained B1OXI cells and S. Typhimurium 4/74 in absence (E) or presence (F) of 10 mg/mL soluble plantain NSP. Arrows indicate bacteria.

经可溶性车前草非淀粉多糖（soluble plantain NSP）预处理30分钟后，可剂量依赖性阻断（A）鼠伤寒沙门氏菌（*Salmonella Typhimurium*）LT2株与（B）鼠伤寒沙门氏菌4/74株对B1OXI细胞的黏附能力；本实验共重复3次，每组设置4个复孔。*（原文此处疑似排版笔误，推测应为标注(C)）* 鼠伤寒沙门氏菌LT2株与（D）鼠伤寒沙门氏菌4/74株对B1OXI细胞的侵袭过程，同样可被车前草NSP阻断。所有数据以均值±标准误（mean ± SEM）表示，以溶剂处理对照组的黏附（或侵袭）水平为100%进行归一化。光学显微镜观察结果展示了未添加（E组）与添加（F组）10 mg/mL可溶性车前草NSP时，吉姆萨染色的B1OXI细胞与鼠伤寒沙门氏菌4/74的形态，箭头指示细菌所在位置。
