The Microbiome in Early Childhood
Thought to be essentially sterile in utero, the human body is rapidly colonized by a range of microbes immediately following birth. These relatively simple microbial communities grow in complexity and differentiate until they reach an adult-like configuration around three years of age. These microbes participate in many complex physiological and immunological processes, such as aiding in digestion, directing immune system development, and excluding pathogens. This process of microbiome maturation is not well understood, but can be crucial for the establishment of a “healthy” microbiome.
Using both microbe-centric and host-centric multi-‘omic approaches, we are investigating this process of microbial community assembly across body sites, as well as how it is altered during periods of disease, treatment, and through interactions with care-takers and their environment.
