Human microbiome

Vocabulary

The human microbiome includes microbial communities associated with the human body and their genetic material.

Explanation or usage

Different body sites support different microbial communities. Many microbes are harmless or beneficial in their usual setting, while some can cause disease in particular conditions. Presence alone does not identify a microbe’s effect or establish a treatment.

Common misunderstandings

Every microbe found on a healthy person must be harmful.
