Fig. 6From: Mucosal immunization with Lactiplantibacillus plantarum-displaying recombinant SARS-CoV-2 epitopes on the surface induces humoral and mucosal immune responses in miceAntibody levels of the seven groups on days 0, 21, and 35 post first immunization. Immunoglobulin IgG in sera (A) and IgA in feces (B) prepared from mice orogastrically administered with surface displayed SARS-CoV-2 epitopes and wild type L. plantarum SK156, respectively. ‘*’ indicates the results of significance testing for the epitope groups versus no treatment group (ANOVA test, *p < 0.01, **p < 0.001; ***p < 0.0001). ‘#’ indicates the results of significance testing for the Day 0 groups versus Day 21 groups and ‘■’ indicates the results of significance testing for the Day 0 groups versus Day 35 groupsBack to article page
