Toxo can cause serious birth defects.

因为刚地弓形虫可能带来严重的出生缺陷。

Rodents ingest little bits of Toxo from cat feces and Toxo goes straight to their heads.

And it turns out that toxo can mess with our brains, too.

Definitive diagnosis of toxo requires radiographic testing (usually a CT or MRI scan).

So is toxo manipulating our brains as an evolutionary strategy to get predatory cats to eat us?
