The first country in the world to approve faecal transplants is Australia.

poo donors who have to meet a list of conditions give healthy genetic material from their microbiomes. Clostridium difficile (C diff) is a potentially deadly disease that can be treated with the collection and delivery of the microbes.

Oral delivery of transplants is expected to be available before too long.

The world's first company to have regulatory approval for a donor-derived microbiome therapy is in Australia.

The Therapeutic Goods Administration approved faecal microbiota transplants as a low-risk biological for the treatment of gastrointestinal disorders.

The product had been available to patients for several years, but regulation would make it a pharmaceutical standard.

He said that they were the first to meet that standard.

Doctors should be reassured by that approval.

Western countries have become less and less hospitable to the human microbiome.

There are links between the microbiome and a number of conditions.

The approval of the TGA for the treatment of recurrent C diff is the only one that opens the way for other conditions.

Vulnerable people can get sick from C diff, a common gutbacteria that can turn toxic. It can be difficult to treat in hospitals.

The library is being built to tackle C diff and other diseases.

Dr Emily Tucker is the head of donor screening at BiomeBank.

While people were unable to travel they weren't picking up exotic gut parasites, and fewer people were getting sick as a side effect of avoiding Covid, so there were fewer colds or antibiotics.

Good donors are called unicorns because of their rarity. Before making a donation in a special donor room, they have to be screened and assessed as healthy. The donors are paid a small amount of money for their time.

It has been difficult.

We have a lot of donors now. It is hard to find them, but they are driven by the desire to provide something that is good.

Tucker says people should talk to their doctor.

Patients would be able to have this therapy if they meet certain criteria.

A second- generation artificial version that can be scaled up and taken to the world was the next stage of the project.

He wants to create a cultured version of the product.

We have a large culture collection of strains of individualbacteria that have been collected from these screened donors and we are working to culture these together to create an artificial version of a faecal community

It would have advantages in the sense that it wouldn't need donors and would be more closely defined in its composition, so you could supply a larger number of patients more easily.
