Mazmanian's team treated the
germ-free animals with individual strains of those microbes.
Many put this trend down to the "hygiene hypothesis" - we're now so
germ-free that our immune systems don't get the chance to become trained to deal with the bugs.
At PACK EXPO, StA[currency]ubli will simulate packaging medical devices in a
germ-free, controlled environment.

Germ-free mice--which are born in sterile conditions and free of all microorganisms--are popular for gut flora research because scientists can inoculate the mice with specific microbes and watch what happens.
This work involved a series of complicated experiments to demonstrate that mice reared
germ-free (GF) are protected from diet-induced obesity and are unable to absorb fat compared to conventionally-raised mice, also known as specific pathogen free (SPF) mice.
Results demonstrated that both
germ-free mice lacking a microbiome and antibiotics-treated mice with a dysbiotic microbiome, failed to mount an effective anti-tumor response following treatment with an anti-PD-1 checkpoint inhibitor.
Moreover, these malevolent dili ingon nato (Cebuano for the 'not-like-us') are dangerous because, like germs, you can't see them, so for good measure as we try to create a
germ-free environment, we use deodorants and air fresheners.
They said that we should endeavour individually and collectively to confront this challenge and make our lives
germ-free and avoid diseases
Here, the animals can live their entire lives in a
germ-free environment without the trillions of microbes that exist in and on humans and animals under ordinary circumstances.
Germ-free mice, laboratory raised without any gut bacteria, are used to determine the role of the gut microbiome on the serotonin system.
The device works by dispensing dog poo bags from one end and hand sanitiser from the other, meaning the owner's hands stay clean and
germ-free when cleaning up dog mess.
To date, the majority of research in this field has been done in
germ-free mice; altering or disrupting their microbiome has been demonstrated to mimic human depression, anxiety, and autism.
