The aim was to study the influence of booster immunization with recombinant fragment of E2 CSFV on humoral immune response, elicited by candidate marker DNA-vaccine against CSF. Methods. The fragment of E2 CSFV gene has been detected by PCR, and the expression of encoded protein – by immunohistochemical analysis. The anti-E2 antibodies in blood serum after immunization have been detected by ELISA. Results. It has been shown that candidate marker DNA-vaccine transfected myocytes of murine biceps in situ. The data of immuno-histochemical analysis revealed the expression of fragment of glycoprotein E2 CSFV from the plasmid introduced. The booster immunization with recombinant E2 led to the significant increase of the titer of antibodies specific to the antigen studied. Conclusions. The data obtained show that boosting with recombinant E2 enhances humoral immune response elicited by the candidate marker DNA-vaccine against CSF.
