Study is one of the few to show the behavioural effects of Toxoplasma gondii in wild animals.
Wolves infected with a common parasite are more likely than uninfected animals to lead a pack, according to an analysis of more than 200 North American wolves1. Infected animals are also more likely to leave their home packs and strike out on their own.
