Autism-like and some other neurodevelopmental disorders in kids can be prevented if their pregnant mothers receive a certain bacteria through the third trimester, reveals a new rat research conducted by the University of Colorado Boulder.

The study team’s article states that when a human mother-to-be experiences during pregnancy, this can lead to systemic inflammatory conditions in both her and the fetus. This amplifies the risks for developing autism, the study says.

After subjecting pregnant laboratory rats to moderate stressors, the research team gave some of them terbutaline, a medication that is frequently given to human women to prevent premature labor. These rats would later produce pups with autism-like features. But the other group of pregnant rats received injections of M. vaccae, a strain of friendly bacteria, which is known for its prolonged anti-inflammatory impacts. Their pups would not show any symptoms of autism disorder.

The researchers, however, stress that they are not producing an “autism vaccine.” But for pregnant people it is always crucial to remember about the various types of stress during pregnancy, they add. As for the “friendly bacteria”, fermented foods can be beneficial.
