The following session we'll cover microbiome and human health, focusing on the definition and composition of the human microbiome and its critical role in our health. We will examine the different microbial groups, their unique functions, and how they interact with our bodies. The lecture will explore how diet, lifestyle, and environmental factors shape the microbiome and the consequences of imbalances. Lastly, we will discuss current and emerging strategies like probiotics and fecal transplants to support a healthy microbiome. The microbiome refers to the diverse collection of microorganisms, bacteria, viruses, fungi, and archaea that live in and on the human body. These microbes and their genes make up the microbiome, while microbiota refers just to the organisms themselves. Invisible to the naked eye, they number in the trillions outnumbering human cells. The gut hosts the richest community shaped by birth, diet, environment, and medications. This ecosystem is now seen as a forgotten organ with vital functions for our health. Our microbiome is a bustling metropolis with a rich variety of residents. The main groups are bacteria, especially fermcutes and bacteroid ETs, plus sactinabcteria, proteobacteria, viral communities, the virum, fungi, and lesser known archaea. Each microbe offers unique abilities like bifidobacterium digesting fibers, while fungi and viruses interact with our cells and other microbes.
