We describe comparative genome analysis of Clostridium perfringens with human genome to identify genes essential for the bacteria’s survival in non-homologous human host to identify potential drug targets. We found only 426 gene potential drug targets compared with 2558 genome’s protein coding genes. The 426 genes were further analyzed for similarity with essential genes of 14 different bacterial species present in Database of Essential Genes (DEG). We found only 5 essential genes of C. perfringens similar to those in DEG. Of these, 1 gene was similar in 12 species and 4 genes similar in 11 species. Thus, the study opens a new avenue for development of broad spectrum antibiotic against highly pathogenic bacterium by selecting these essential common genes in pathogenic microbial species. As a case study, we constructed a homology model drug target, ABC transporter-ATP binding protein, for in silico docking.
