Mycobacterium bolletii, a sub-species of Mycobacterium abscessus, a rapidly growing non-tuberculosis mycobacterium is isolated from respiratory and subcutaneous infection. The pathogen shows resistant to several antimicrobial drugs especially to clarithromycin. To reduce the effect of disease caused by Mycobacterium abscessus subsp. Bolletii pathogen the new drug is to be introduced which is non-resistant with them, for which drug target identification is a beneficial step not only for reducing the adverse effect of drug over the host but it’s also effective over the pathogen. In the present study a novel in silico approach is applied for target identification comprising four different phases. The first phase executes selection of protein data set that were filtered in phase II during substractive analysis having six different sub-phases of screening. The resultant proteins obtained at the end of phase II is subjected to quantitative analysis in phase III and finally Interactome analysis in phase IV. Finally, at the end of phase IV,9 proteins out of 5134 were identified as potential drug targets of Mycobacterium abscessus subsp. bolletii, 50594. As these 9 proteins were non-homologous with the complete proteome of Homo sapiens, gut flora microbes, anti-targets, homologous with essential genes having molecular weight less than 110 kb and are non-hypothetical proteins. These 9 proteins are also found in cytoplasm having more than 5 interactors.
