Study on how bacteria obtain essential nutrients in soil, during infection

October 19, 2020

Much like humans eat food in order to obtain essential nutrients, bacteria acquire nutrients by importing them. An essential nutrient for life is zinc, which cannot be manufactured, and therefore must be obtained from the environment. However, the availability of zinc is frequently limited. This is exemplified by a defense mechanism, nutritional immunity, used by the immune system to prevent infections in which the body withholds metals, such as zinc, to combat invading bacteria.

Study reveals how bacteria steal nutrients from human hosts

November 2, 2017

A new study, published in mBio, exposes a zinc-import system in bacteria that could contribute to their ability to cause infection.

The study looked at how the bacterium Staphylococcus aureus, which can infect virtually all of the tissues in the human body, competes with the immune system for the essential nutrient zinc.
