Yes they do, just look at the Royal parasites from England…Hehehe
“The parasite grows in a rodent, but it needs to get into a cat somehow to reproduce,” says Shelley Adamo, a biologist who studies neuroparasitology at Dalhousie University in Halifax, Canada. “When a rat becomes infected, the parasite somehow makes rats become attracted to cat urine, when it would normally avoid it.”
Estimates from the Centre for Disease Control (CDC) suggest that more than 60 million Americans carry the single-celled parasite, most often obtained through ingesting undercooked meat or interacting with cats. The CDC claims that “of those who are infected very few have symptoms because a healthy person’s immune system usually keeps the parasite from causing illness.” This new information may force scientists to reconsider that statement, however.
New Research on Parasites
A study published in the Journal of Experimental Biology by Jaroslav Flegr, a scientist at Charles University in Prague, suggests that people who are infected with this parasite have slower reaction times and are often “less altruistic” than uninfected people.
Researchers determined that women who were infected with Toxoplasma “more often report that diplomacy is not their strong point” and that “some people have the power to impose their will on others with hypnosis.” They also described women having “a weak instinct for self-preservation: in situations where somebody else might be afraid, for example being alone in a forest or in an empty house at night, they remain calm.”
Flegr acknowledges that they “cannot distinguish whether the observed changes are manifestations of the manipulative activity or only symptoms of the chronic disease” often caused by Toxoplasma, but Toxoplasma infection’s prevalence, nevertheless, makes it an ideal “model for studying manipulative activity in humans.” There are a “large number of parasitic organisms … that may influence the human host even more than the Taxoplasma,” he continues.
