pubmed:abstractText |
DNA-based immunization has shown to be a viable alternative approach to induce protective immunity against Brucella abortus infection. However, the use of a unique gene may not be sufficient to induce full protection. Therefore, a new strategy based on library immunization has been described to improve the level of protection against different pathogens and to identify new protective genes. In the present study, a B. abortus library was subcloned into the mammalian expression vector pCMV-Ubi. This plasmid was designed to create a fusion between the gene of interest with ubiquitin. The analysis of this Brucella-library showed approximately 72% of clones containing inserts with an average size of 500-2000 bp. Further, homology searches were performed using the BLASTn program, and all sequenced clones showed homology with Brucella genes, as expected. BALB/c mice immunised intramuscularly with the Brucella genomic expression library showed a strong specific total IgG antibody response to a Brucella protein extract, with production of IgG1 and IgG2a isotypes. Regarding cellular immunity, high levels of IFN-gamma and no IL-4 were detected in primed mouse splenocytes and partial protection against infection was reached in animals vaccinated with the Brucella library compared to the control group.
