Using available sequencing methods, it is now possible to determine the presence of healthy or disarrayed microbiomes.

Detailed explanation-3: -The main types of bacteria in the colon are obligate anaerobes, and the most abundant bacteria are members of the genus Bacteroides, anaerobic gram-positive cocci, such as Peptostreptococcus sp., Eubacterium sp., Lactobacillus sp., and Clostridium sp.

Detailed explanation-4: -The concentration of microbiota increases steadily along the gastrointestinal tract, with small numbers in the stomach, but very high concentrations in the colon.

Detailed explanation-5: -Microbes inhabit just about every part of the human body, living on the skin, in the gut, and up the nose. Sometimes they cause sickness, but most of the time, microorganisms live in harmony with their human hosts, providing vital functions essential for human survival.
