Maharishi Dayanand University

Dr. Nar Singh Chauhan is currently a teaching faculty in the Department of Biochemistry, Maharishi Dayanand University, Rohtak, India. His doctor of philosophy degree, with thesis research on \'Arsenic detoxification mechanisms in unculturable bacteria using function metagenomics\' at the CSIR-Institute of Genomics and Integrative Biology, was granted by Savitribai Phule Pune University, Pune, India. His current research focus is on the metagenomic characterization of diverse microbiome for their native community structure, physiological functions, survival strategies under abiotic stress, colonization factors, and host-microbial interactions. In this direction, he has established an association of the human microbiome with the onset of celiac disease and chronic obstructive pulmonary disease. Dr. Chauhan is the author of a number of peer-reviewed research publications in reputed international journals (Genome Biology & Evolution, Scientific Reports, Frontiers in Microbiology, etc.) and has also been awarded many research patents.

Microbes are ubiquitous and have ecological interactions with almost all life forms. Likewise, humans invariably engage in host-microbial interactions that could induce short-term or long-term effects. Some of these long-term crossover interactions have allowed successful colonization of microbes within or on the human body, collectively known as the human microbiome or human microbiota. The human microbiome is identified as playing a key role in various physiological processes like digestion, immunity, defense, growth, and development. Any dysbiosis in the human microbiome structure could induce the onset of various metabolic or physiological disorders. Cumulatively, the human microbiome is considered as a virtual human organ that is essential for host survival. Additionally, short-term biological interactions of the host and microbes have exposed microbes to the human cellular system. This exposure could have allowed the microbes to invade human cells for their growth and reproduction-induced onset of various infectious diseases. This book incorporates a number of studies highlighting the role of microbes in human health and diseases.
