AB - This study examined the recombinant Attenuated Salmonella
Choleraesuis C500 containing M and N gene of PEDV whether can
induce a systemic immune responses in mice. After identified by enzyme analysis
and nucleotide sequencing test, the constructed recombinant plasmid, designated
as pIRES-M-N was transfected into Vero cells. The transient expression protein
was detected by indirect Immunofluorescence Assay (IFA) and Western-blotting.
Result showed that pIRES-M-N can be expressed correctly in Vero cells. Then,
the recombinant plasmid electroporated into S. choleraesuis C500 and
the recombinant bacteria was proved to be stabile in vitro. The immunogenicities
of this recombinant attenuated salmonella constructs were firstly investigated
in a mouse mode. Specific anti-PEDV IgG antibodies and IFN-γ, IL-4 of cytokine
were detected. The result showed that the recombinant Attenuated Salmonella
could induce higher persistence specific hummune responses in mouse by contrast
with naked DNA group after 42 days (p<0.05). It also, stimulated a balanced
Th1/Th2 immune response. That provided the clinical basic data and theoretical
basis for success of the attenuated salmonella vaccine development.
