Recombinant vector for expressing immunogenic protein of porcine epidemic diarrhea virus (pedv), recombinant strain including the same, and use thereof

Abstract

A recombinant vector for expressing an immunogenic protein of porcine epidemic diarrhea virus (PEDV), a recombinant strain including the same and use thereof are provided. The recombinant vector for expressing the immunogenic protein S1B of the PEDV is provided, and the recombinant vector can be used to construct a recombinant Lactococcus lactis strain expressing the immunogenic protein S1B of the PEDV. The recombinant Lactococcus lactis strain and an expressed antigen protein S1B of the PEDV are mixed to prepare a microbial agent capable of preventing PEDV infection. The created microbial preparation may safely, effectively, and quickly prevent the PEDV infection in pigs and does not involve an immunization process.
