NIAID is home to one of the few facilities in the United States that houses so-called gnotobiotic mice. These mice are born in germ-free conditions, and investigators control the microbiota by inoculating the animals with specific microorganisms. The word “gnotobiotic” comes from the Greek words gnostos, for known, and bios, for life. “}}
