What is it about?
We find a generational effect of early adversity (parental separation) in rodents whereby fear retention and extinction development is affected in the infant offspring of previously stressed fathers. We then find that probiotics are an effective treatment for these effects when they are administered to either the father (in his early life), or to the infant offspring.

Why is it important?
Generational effects of early adversity and gut microbiome effects on emotion functioning are two burgeoning fields. However, few studies have connected the two areas. This paper is the first to demonstrate that gut manipulations are an effective treatment for generational stress effects, suggesting that the microbiome might be important in the transmission of stress across generations.
