Abstract

This performed an in silico analysis of htrA gene as an molecular marker to phylogenetic and identifications studies of mycobacterium species. The htrA sequeces of M. tuberculosis, M. bovis, M. leprae, M. ulcerans, M. marinum, M. abcessus were obtained from GenBank (NCBI). The phylogenetic trees generated by Neighbour-joining, Maximum parsimony and UPGMA methods and showed a division between slow growing and rapid growth species. The Maximum parsimony method was also able to distinguish between strictly pathogenic, potentially pathogenic and saprophytic species. The results show htrA as an alternate tool for identification and classification of mycobacterium species.
