The nontuberculous mycobacteria (NTM), which include over one hundred Mycobacterium species, are environmental opportunistic pathogens of humans and animals, including pigs, fish, and poultry. NTM are causative retailers of pulmonary disease, cervical lymphadenitis, skin, disseminated (bacteremia), and nosocomial infections. Because in their hydrophobic, wax- and lipid-wealthy cell envelope, NTM are found in biofilms, are proof against a wide type of disinfectants and antibiotics, and can continue to exist in some of habitats wherein they can are available in contact with prone species. As the common age of human populations inside the advanced world increases and a extra percentage become immunosuppressed, far in all likelihood that the superiority of environmental mycobacterial infections will preserve to increase. The top online publishing journals publish articles which are cited as references by many authors in their work. Citations are important for a journal to get impact factor. Impact factor is a measure reflecting the average number of citations to recent articles published in the journal. The impact of the journal is influenced by impact factor, the journals with high impact factor are considered more important than those with lower ones. Indexing provides easy access of the article online. The international journals are among the best open access journals in the world, set out to publish the most comprehensive, relevant and reliable information based on the current research and development on a variety of subjects. This information can be published in our peer reviewed journal with impact factors and are calculated using citations not only from research articles but also review articles (which tend to receive more citations), editorials, letters, meeting abstracts, short communications, and case reports. The inclusion of these publications provides the opportunity for editors and publishers to manipulate the ratio used to calculate the impact factor and try to increase their number rapidly. Impact factor plays a major role for the particular journal.
