Withdrawn and anxious, the mice in John Cryan’s lab had been behaving such as you or I would if we had skilled office bullying and thought we’d encounter the bully once more.
The excellent news, consider it or not, was that a few of these rodents had been additionally being fed a slurry of microbes derived from their very own faeces. Unpalatable as this sounds, it had a surprisingly constructive impact on their behaviour. “It was phenomenal,” says Cryan, a neurobiologist at College Faculty Cork in Eire. “We discovered that these stress-induced modifications in behaviour normalised – they began to behave identical to regular animals.”
Much more stunning, this psychological transformation wasn’t led to by altering the micro organism of their guts, however by tinkering with one other essential aspect of the microbiome whose significance is simply now being recognised: viruses.
It seems that we’re riddled with these.
