This book in the two volume set provides comprehensive coverage on how microbial pathogens can subvert our immune system into responding against self and resulting into 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 focuses on the role of microbiota/probiotics and their distinct mechanisms exerted in management of autoimmune liver, skin, thyroid, rheumatic and myopathic diseases. This could help in better understanding to design therapeutic strategies that can be deployed to prevent these autoimmune diseases. The book has an interdisciplinary appeal and scholars with an interest immunology, medical microbiology and nutritional sciences will value its contribution. Overall, the book gives a new dimensions and insight in the aspects of microbial role in autoimmune disease pathogenesis and therapeutic aspects.
