Question

Describe the human microbiome (in broad terms) - include the following: What types of organisms is the human microbiome composed of? (Which classes of microbes are & are not represented?) Where is the microbiome located? (Where present, and where absent?) How does the microbiome help its host? (Name one benefit our microbiome provides us). How does a host help its microbiome? (Name one benefit we provide to our microbiome).

Answer 1

The microbiome is defined as the collective genomes of the microbes (composed of bacteria, bacteriophage, fungi, protozoa and viruses) that live inside and on the human body. We have about 10 times as many microbial cells as humancells.

Microbiome are generally located in human gut.

Most members of the human microbiota benefit humans by providing them with traits that they would not otherwise possess. Some microorganisms found in the human gut, for instance, obtain nutrients from ingested food in return for assisting with the breakdown of food or preventing the colonization of the gut by harmful bacteria, like lactobacillus.

There are, however, many microorganisms in the human microbiota that are pathogenic. For example, bacterial species of the genera Staphylococcus, Streptococcus, Enterococcus, Klebsiella, Enterobacter, and Neisseria.

disease in human body, largely effect the diversity of gut microbiota.
