Figure 4. IgA antibody content in tears of SPF chickens immunized with PBS (i.m.), blank PLGA-NPs (i.m.), blank PLGA-NPs (i.n.), and the naked plasmid DNA (i.m.), pFNDV-PLGA-NPs (i.m.), pFNDV-PLGA-NPs (i.n.) or pFNDV-PLGA-NPs (i.m./i.n.).

Figure 4

(A) IgA antibody content in tears; (B) IgA antibody content in tracheal fluid; (C) IgA antibody content in bile; (D) IgA antibody content in serum. IgA antibody content was presented as mean ± SD of five experiments. Data with different small letters show significant difference (p<0.05).
