Faecal transplants ‘could save endangered koala’

Scientists believe they have found a new weapon in the battle to save endangered species: faecal transplants. They say that by transferring faeces from the gut of one animal to another they could boost the health and viability of endangered creatures. In particular, they believe the prospects of saving the koala could be boosted this way.

The idea of using faecal transplants as conservation weapons was highlighted this month at the American Society for Microbiology meeting in Atlanta, where scientists outlined experiments in which they used the technique to change microbes in the guts of koalas.

Microbes play a key role in digesting fibres in the animal’s diet of eucalyptus leaves – which come in two main varieties: manna gum and messmate.

“Messmate is clearly inferior to manna gum: it has less protein and more tannins,” said the project leader, Ben Moore of Western Sydney University.

However, some koalas eat only messmate and others only manna gum. Few eat both – and that is because manna-gum-eating koalas have different bacteria in their guts from those that ate messmate.
