Pathogenic mycobacteria have evolved the mechanisms to subvert host immune response in the favor of longtime persistence and proliferation in the intercellular environment of the host, with resulting in functional dysregulation and disease in the host. Among the genus mycobacteria, Mycobacterium avium subspecies paratuberculosis is a robust pathogen, have a remarkable capacity to persist in the host and adverse environmental conditions (pasteurization temperature, high pH) and recently, emerged as a major concern of public health significance. Mycobacterium avium subspecies paratuberculosis is the causative agent of Johne’s disease in animals and also has been incriminated as the causative agent of Crohn’s disease in human beings. Therefore, understanding the factors that contribute to the longevity of this pathogen is essential to restrict the clinical outcomes of infection and design the control strategies. The present review summarizes our understanding of factors that contribute to the survival of MAP within the host and different environmental sources.
