The effect of antibiotics on social aversion following early life inflammation.

Epidemiological evidence suggests that exposure to infection during early development increases the risk for neurodevelopmental disorders associated with symptoms such as a decreased desire to engage in social interactions. In animals, disruptions in social behavior can be modelled by administering bacterial mimetics such as liposaccharide (LPS). However, when evaluating social interactions in the laboratory, attention is rarely directed on the reciprocal relationship as a whole, which is important as peers may drive social withdrawal.
