Fig. 6From: Immunogenicity evaluation of recombinant Lactobacillus casei W56 expressing bovine viral diarrhea virus E2 protein in conjunction with cholera toxin B subunit as an adjuvantThe percentages of B220+IgM+ B cells, B220+IgA+ B cells, B220−IgA+ plasma blast, and total IgA+ cells in the PPs of the mice in each group were determined on day 7 after oral vaccination. The letters (a vs. b, c vs. d) indicate significant difference (p < 0.05); the letters (a vs. c, b vs. c, b vs. d) indicate significant difference (p < 0.01); the letters (a vs. d) indicate significant difference (p < 0.001)Back to article page
