Abstract: In order to promote the research and development of Brucella Rev.1 vaccine and related vaccines, the nucleic acid of the Brucella Rev.1 vaccine strain was extracted, and the genome-wide sequencing for Brucella Rev.1 vaccine strain was carried out and analyzed through PacBio platform. The results showed that the full-length genome of the Brucella Rev.1 vaccine strain was 3 299 187 bp, and the G+C content was 57.2%; two circular genomes of chromosome 1 and chromosome 2 were assembled; the size of chromosome 1 and chromosome 2 was 2 121 370 bp and 1 177 817 bp, respectively, and the G+C content of chromosome 1 and chromosome 2 was 57.2% and 57.3%, respectively. The sequences of Ery, BLS and VirB10 genes of the Brucella Rev.1 vaccine strain were bioinformatically compared and analyzed with their counterparts of 9 Brucella reference strains, and the sequence similarity among those genes were observed, ranging from 97.4% to 100%.

Key words: Brucella, Brucella Rev.1 vaccine strain, genome-wide sequencing, gene sequence comparison
