| Summary |
Brucellosis is one of the most common zoonotic epidemics worldwide. Vaccination against Brucellosis is an important control strategy to prevent the disease in many high-prevalence regions. At present, Brucella vaccine strain S2 is the most widely used vaccine in China. In this study, to uncover the related mechanisms underlie virulence attenuation of S2, we characterized the transcriptional profile of S2 and 1330 infected macrophages by transcriptome analysis. The results revealed that expressions of 440 genes were significantly different between macrophages infected by 1330 and S2. Data analysis showed that in the gene ontology term, the different expressed genes involved in innate immune response, phagoctyosis, recognition, and inflammatory response were significantly enriched. Pathway enrichment analysis indicated that the genes involved in transcriptional misregulation in cancer, staphylococcus aureus infection pathways and NF-kappa B signaling pathway were significantly affected. To reveal the molecular mechanisms related to different expression profiles of infected macrophages, the transcription levels of the different genes between the two bacterial genomes were also detected. In total, the transcription of 29 different genes was significantly changed in either culture medium or infected microphages. The results of current study can be conducive to the promotion of better understanding of the related mechanisms underlie virulence attenuation of S2 and interactions between host cells and brucella strains.
