Gut flora (gut microbiota, or gastrointestinal microbiota) is the complex community of microorganisms that live in the digestive tracts of humans and other animals, including insects. The gut metagenome is the aggregate of all the genomes of gut microbiota. The gut is one niche that human microbiota inhabit.
Probiotics are live microbial organisms that are naturally present in the digestive tract and vagina. The digestive tract maintains a balance between healthy and potentially harmful micro-organisms. Healthy micro-organisms, also called microflora, are residents of the digestive tract that have a protective role in our bodies. There are over 400 species of microorganisms in the human digestive tract, including Lactobacillus and Bifidobacterium.
