While the parasite hasn't caused widespread pandemics, its complex life cycle and influence on rodent behavior have opened new avenues of research into how parasites may manipulate hosts, including humans. The simultaneous discovery of toxo on opposite sides of the globe highlights its extensive presence long before it was studied.
