in mice
Figure 1: BSA specific antibody response (IgG1, IgG2a, IgA and IgE) elicited after oral immunization in mice. BALB/c mice (n=6) were orally immunized with a single dose of BSA (80 μg) either free or adjuvanted with 10 μg of CT (cholera toxin) or rVTX1 (recombinant verotoxin). Antibody response was determined up to 5 weeks. Significant differences between CT and rVTX1 groups are indicated by asterisks (*P. 0.05).
