1,*Brucellosis is an important cosmopolitan infection disease caused by organisms belonging to the genus Brucella. The cgt gene (cyclic ?-1, 2 glucan transporter gene) is a virulent factor in Brucella genus. The present study was conducted with the aim of cloning and expression of Brucella cgt gene.
Brucella melitensis cgt gene was amplified from extracted chromosomal DNA by PCR, then
The PCR product was cloned in pTZ57R plasmid via T/A cloning method. Recombinant plasmid was digested by BamHI and SacI restriction enzymes, the released band was purified and subcloned into pGEMEX-1 expression vector. Then, sample cells were lysed using lyses buffer and sonicated, then electrophoresed on SDS-PAGE. Protein bands were transferred on nitrocellulose membrane and reacted by patient's serum and detected by HRP conjugated anti
We cloned and expressed Brucella abortus cyclic -1, 2-glucan transporter gene (cgt) which is an important agent in brucellosis. Using cgt gene mutant may be an effective way for inhibiting or decreasing the pathogenicity of bacteria
