Aim: The present study was aimed at polymerase chain reaction (PCR) amplification and cloning of NAD-dependent betahydroxybutyryl coenzyme A dehydrogenase (BHBD) gene of Clostridium chauvoei.

Materials and Methods: C. chauvoei was cultured and confirmed by 16-23S rDNA spacer region primers. The primers for nad-bhbd gene ofC. chauvoei were designed to aid in cloning into pRham-N-His SUMO-Kan vector, and nad-bhbd gene was amplified by PCR. The amplifiednad-bhbd gene was purified and cloned into pRham-N-His SUMO-Kan expression vector. The recombinant plasmid was transformed into E. cloni 10 G cells and the clone was confirmed by colony PCR using the pRham-SUMO-NAD-For and pRham-SUMO-NAD-Rev primers and also by sequencing.

Results: PCR amplification of nad-bhbd gene yielded a product length of 844 base pairs which was cloned into pRham-NHis SUMO-Kan vector followed by transformation into E. cloni 10G chemically competent cells. The recombinant clones were characterized by colony PCR, sequencing, followed by basic local alignment search tool (BLAST) analysis to confirm the insert.

Conclusions: Immunogenic protein NAD- dependent BHBD of C. chauvoei was cloned and the recombinant clones were confirmed by colony PCR and sequencing analysis.
