“…OMP Brucella abortus has been successfully identified and classified into three groups which were the group 1 of the protein which molecule weight is around 88 -94 kDa, group 2 which molecule weight is around 36 -38 kDa, and the group 3 which protein weight is around 25 -27 kDa 10 . Meanwhile, the gene with OMP codes of 36 to 38 kDa is the Omp2 while the gene of Omp 25 holds the codes of OMP 25 to 27 kDa and the Omp 31 is for the codes of OMP 31 to 34 kDa 11,12 . Brucella abortus local isolate has the virulence factor in the form of lipopolysaccharide (LPS) and outer membrane protein (OMP).…”

Brucellosis is a disease that can be prevented through vaccination. Yet, the effectiveness of the vaccination to fight this disease is considered weak. Fortunately, attempts to modify brucellosis vaccine is still keep going. Some brucellosis vaccines have been found and developed in the past time such as the vaccine B.abortus strain 19-BA and 104M which was made from weakened microbes which had been widely used in Uni Soviet and China. The other brucellosis vaccine that were used in the past were the phenolinsoluble peptidoglycan vaccine which was made in France and polysaccharideprotein vaccine which was used in Russia. This research attempted to see the determinant of antigenic Outer Membrane Protein (OM) 36 kDa Brucella abortus local isolation which has immunogenic character to be developed as an advanced brucellosis vaccine. The method used in this research was the Omp2 gene of Brucella abortus of local isolate employed the PCR technique. The result of the PCR was then sequenced to analyze the determinant antigenic and the bounding prediction of either the T cell or the B cell which were responsible for immune response. The result of this study showed that the gen Omp2 which encoded the OMP 36 kDa Brucella abortus of local isolation with primary JPF 5’ GCG CTC AGG CTG CCG ACG CAA 3’ and JPR 5’ CAT TGC GGT CGG TAC CGG AG 3’ targeted the gene 162 bp, was then translated into amino acids to be later undergo the in silico test using Kolaskar and Tongaonkar Antigenicity Prediction method. The epitope prediction resulted were MSRVCDAYGAGYFYI and TETCLRVHGYVRYD. The result of the epitope prediction of MSRVCDAYGAGYFYI showed that there was a bond with MHC I in YGAGYFYI of the 8th amino acid series to the 15th series, while the epitope prediction of TETCLRVHGYVRYD showed that there was a bond to the ETCLRVHGY of the series of amino acids number 2 to 10. Bond with MHC II existed in the amino acid series of MSRVCDAYGAGYFYI, while the bond with the B cells existed in BCSAYGA and CLRVHG amino acid series. This research has been successful in predicting the epitope of the OMP 36 kDa Brucella abortus of local isolate which had immunogenic characteristic for its ability to bond with the MHC I, MHC II and B cells.
