Several studies have found that humans with autism are also more likely to have gastrointestinal disorders, suggesting that the two problems may be linked…[the researchers] found that mice with symptoms of autism had lower levels of a bacterium called Bacteroides fragilis that is normally present in the mouse gut.
I know I should be all, FETCH THE BACTEROIDES FRAGILIS, but I got stuck on mice with symptoms of autism. There are autistic mice? Are there other animals with autism? And if so, why do we know still so little about autism overall?
