Mycobacterium avium subsp. paratuberculosis Virulence: A Review

To propose a solution for control of Mycobacterium avium subsp. paratuberculosis (MAP) infections in animals as well as in humans, and develop effective prevention, diagnostic and treatment strategies, it is essential to understand the molecular mechanisms of MAP pathogenesis. In the present review, we discuss the mechanisms utilised by MAP to overcome the host defense system to achieve the virulence status. Putative MAP virulence genes are mentioned and their probable roles in view of other mycobacteria are discussed. This review provides information on MAP strain diversity, putative MAP virulence factors and highlights the knowledge gaps regarding MAP virulence mechanisms that may be important in control and prevention of paratuberculosis.

Automated summary

This review discusses the mechanisms utilized by MAP to overcome the host defense system to achieve virulence, including putative MAP virulence genes and their probable roles in comparison to other mycobacteria. It also highlights the importance of understanding MAP virulence mechanisms in controlling and preventing paratuberculosis.
