This book, which is the second volume of Role of Microorganisms in Pathogenesis and Management of Autoimmune Diseases, provides comprehensive coverage on how microbial pathogens can subvert our immune system into responding against self and resulting in autoimmune diseases. In particular, the book covers the different aspects of linking gut microbiota dysbiosis with autoimmune mechanisms involved in disease development to identify future effective approaches based on the gut microbiota for preventing these autoimmune diseases. Contributions in the book focus on the role of microbiota/probiotics and their distinct mechanisms exerted in the management of autoimmune diseases of the kidney, central nervous system, eye, blood vessel, and bowel. This could help in better understanding to design of therapeutic strategies that can be deployed to prevent these autoimmune diseases.
