This volume discusses the oral microbiome, and oral and systemic health. The chapters in this book cover topics such as analytical techniques for identifying and measuring oral bacteria; strategies for controlling common sources of variability in oral microbiome methods for viral bacterial and fungal analysis; ways to study oral DNA and RNA samples to identify molecular pathways to disease; approaches to functional assays for oral bacteriophage, antibiotic purging of systemic bacteria; and metaproteomic analysis of various oral samples. Written in the highly successful Methods in Molecular Biology series format, chapters include introductions to their respective topics, lists of the necessary materials and reagents, step-by-step, readily reproducible laboratory protocols, and tips on troubleshooting and avoiding known pitfalls.
