Abstract:

The experiment was conducted to investigate the effect of oral immunization with H5N1 inactivated avian influenza virus (IAIV) and adjuvant levamisole hydrochloride(LMS),Poly(I:C),Polyethyleneimine (PEI) respectively on the number and distribution of antibody secreting cells in chicken jejunum and ileum.Chicken were immunized through the oral route with H5N1 IAIV and adjuvants LMS,Poly(I:C) and PEI respectively,IgA and IgG secreting cells were detected by Immunohistochemistry to evaluate the immune effect.The number of IgA and IgG secreting cells in jejunum and ileum induced by PEI plus H5N1 IAIV were substantially (P<0.05) greater than antigen-alone treatment.The number of IgA secreting cells in jejunum and ileum induced by LMS and Poly(I:C) plus H5N1 IAIV were substantially (P<0.05) increased than antigen-alone treatment,the number of IgG secreting cells have no changes.Our study showed that chicken oral immunization with H5N1 IAIV and adjuvant LMS,Poly(I:C) and PEI respectively strengthen intestinal humoral immune level in intestine,but the cost of PEI was cheapest and most effective oral immune adjuvant.
