---|---|
the multiplication of organisms in a tissues of a host is called | infection |
indigenous micro flora are microbes that | live on the skin or in the body |
the relationship between human hosts and indigenous flora is called | symbiosis |
both organisms benefit from and depend on one another to certain extent is called | mutualism |
