Fig. 6From: Recombinant L. lactis vaccine LL-plSAM-WAE targeting four virulence factors provides mucosal immunity against H. pylori infectionGastric histology and protective effects were investigated. (a) Experimental protocol for preventing the efficacy of recombinant L. lactis vaccination in the treatment H. pylori infection in BALB/c mice. (b) qPCR analysis of H. pylori. (c) CFU counting of bacterial colonies per mouse stomach. (d) Detection of urease activity at OD550 nm. (e-f) Gastric histological characterization (HE staining 100× and inflammation score). (g) Immunohistochemistry of the gastric tissue (100×). Tissue sections were counted for positive spots, which indicate the number of H. pylori- positive cellsBack to article page
