The relationship between the composition of the gut microbiome and various human diseases, such as inflammatory bowel disease, cardiovascular disease, metabolic disorders, and cancer, has been intricately detailed over the past ten years. Today, cutting-edge technologies like whole-genome sequencing, bioinformatics, and precision gene-editing methods are being integrated with age-old treatments like fecal microbiota transplantation to translate ongoing research into innovative diagnostics and therapies for treating complex diseases. Bugs as Drugs offers a comprehensive overview of microbial therapies, serving as a valuable resource for researchers and medical professionals engaged in studying the microbiota’s impact on health and disease.

In Bugs as Drugs, Robert A. Britton and Patrice D. Cani have curated an engaging compilation of reviews that explore the history, current advancements, and future possibilities of utilizing microorganisms to combat diseases and enhance well-being. The book covers a range of topics, including the traditional use of probiotics, emerging microbial therapeutics, strategies for managing infectious diseases, and indirect methods for influencing the host microbiome. Key areas of discussion include:

1. The role of established probiotics in supporting host health by enhancing the gut microbiota composition and modulating the host’s immune response.
2. The application of gene editing and recombinant DNA technologies to develop customized probiotics and identify next-generation beneficial microbes. For instance, genetic modifications that enhance the anti-inflammatory properties of probiotics can reduce the formation of colonic polyps, while lactobacilli can be engineered to serve as targeted delivery systems for therapeutic proteins or bioengineered bacteriophages.
3. The correlation between specific microbiota compositions and conditions such as colorectal cancer, liver diseases, osteoporosis, and inflammatory bowel disease.
