Microbe reverses an autismlike behavior in mice

Scientists were able to reverse an autismlike behavior in mice after treating them with a single species of bacteria, The Scientist reports. Mice with autismlike symptoms had fewer Lactobacillus reuteri bacteria in their guts, which has previously been shown to boost levels of a hormone called oxytocin, involved in social bonding. When the team gave the mice this species of bacteria through their water, their social deficits seemed to disappear, the team reports in Cell. Their anxiety and repetitive behavior did not improve after treatment, however.
