quote:

The results were clear. Women with Toxoplasma infections were 54% more likely to attempt suicide – and twice as likely to succeed. In particular, these women were more likely to attempt violent suicides (using a knife or gun, for example, instead of overdosing on pills). But even more disturbing: suicide attempt risk was positively correlated with the level of infection. Those with the highest levels of antibodies were 91% more likely to attempt suicide than uninfected women. The connection between parasite and suicide held even for women who had no history of mental illness: among them, infected women were 56% more likely to commit self-directed violence.

While these results might seem frightening, they make sense when you think about how Toxoplasma is known to affect our personalities. In 2006, researchers linked Toxoplasma infection to neuroticism in both men and women. Neuroticism – as defined by psychology – is the “an enduring tendency to experience negative emotional states,” including depression, guilt and insecurity. The link between neuroticism and suicide is well established, thus if the parasite does make people more neurotic, it’s not surprising that it influences rates of self-violence.

An infected cat can excrete up to 20 million oocysts over two weeks…Even a single oocyst is infectious and they can remain infectious in water for up to six months and in warm moist soil for up to a year.
