provides insight into the interaction of microbial metabolic pathways in the human body and the impact these can have on a variety of diseases. By analyzing these pathways the book seeks to investigate how these metabolic processes can be targeted and manipulated in order to treat various disorders and diseases. Topics covered in the book include microbial shikimate pathways, protein biosynthesis, tryptophan metabolites, microbiome metabolic engineering, fecal microbiota transplantation, and virulence factors. Additionally, a variety of conditions are covered, such as disorders associated with metabolic syndromes, serotonin syndromes, Alzheimer’s disease, and Covid-19, providing a detailed overview of how metabolic pathways of microbiome can impact health and disease in the human body.
