Abstract

The Capripoxvirus (CaPV) has a large double‑stranded DNA genome and a restricted host‑range. At present, it is being investigated as an ideal vaccine vector. In the present study, a novel recombinant goat pox virus (rGTPV) was constructed to express Brucella outer membrane protein (OMP)25, and was validated by in vitro and in vivo immunization assays. A novel rGTPV vector was created, in which the thymidine kinase gene was used as a flanking sequence, I1L was inserted as a promoter element to enhance Brucella OMP25 expression, and p7.5 as another promoter element was used to regulate guanine phosphoribosyl‑transferase as a selection maker. The rGTPV vector was transfected into sheep fetal fibroblast/lamb testis cells pre‑infected with GTPV G14‑STV44‑55 to recombine. Brucella OMP25 protein was expressed in cells by rGTPV, and activated immune reactivity to Brucella OMP25 protein, as detected by western blotting. Furthermore, rGTPV elicited, anti‑Brucella‑specific immunoglobulin G responses, as determined by ELISA. Mice vaccinated with rGTPV did not exhibit pathology alterations in the kidney and liver. These results suggested that the novel rGTPV was able to efficiently drive Brucella OMP25 protein expression and activate immune reactivity, and may have applications in CaPV live vector vaccines and associated research.
