culture of the gastrointestinal tract

The gastrointestinal (GI) tract hosts a diverse community of microorganisms, including bacteria, fungi, and viruses, collectively called the microbiota. These microbes play a crucial role in digestion, breaking down food nutrients, producing vitamins, and supporting immune function. They help maintain a healthy balance, preventing harmful organisms from thriving. The composition of this microbial ecosystem varies between individuals and can be influenced by diet, antibiotics, and lifestyle. A balanced GI microbiota is essential for overall health, affecting digestion, immunity, and even mental well-being.
