microbe

Medications a person took years ago can still influence the community of microbes living in their gut, according to a large study conducted by the University of Tartu Institute of Genomics.

While human bodies can manufacture these fatty acids, the molecules also are found in dairy products and human breast milk and are made by certain gut microbes.

Humans are constantly exposed to microbes that could make us sick, and the immune system developed to protect us.

Their experiments showed that a short blast of ultraviolet light killed the microbes and banished the stink.

The microbe used by Stephen Wallace, professor of chemical biotechnology at the University of Edinburgh, was Escherichia coli, better known as E. coli.
