Infected mice lose their fear of cats, which is good for both cats and the parasite, because the cat gets an easy meal and the parasite gets into the cat’s intestinal track, the only place it can sexually reproduce and continue its cycle of infection.

“The idea that this parasite knows more about our brains than we do, and has the ability to exert desired change in complicated rodent behavior, is absolutely fascinating,” Ingram said. “Toxoplasma has done a phenomenal job of figuring out mammalian brains in order to enhance its transmission through a complicated life cycle.”

Researchers found that mice’s lack of fear of cats persisted even when inflammation markers or cysts could not be detected in mice. (Credit: Wendy Ingram and Adrienne Greene)
