"One such example is Toxoplasma infection of rodents. Toxoplasma
gondii is a protozoa that reproduces in the intestines of cats, and is
also the reason why pregnant women shouldn't change cat litter boxes.
Although its sexual reproduction happens in the cat's innards, it has
a two-part life cycle, and oocysts are then excreted by the cat.
Animals that come into contact with the feces become infected, and if
they're unfortunate enough to be eaten by a cat later on, the
Toxoplasma bug has scored a win and goes on to start a new cycle.

Here's the interesting bit: Toxoplasma fixes the odds. A new study
from Ajai Vyas and colleagues at Stanford University, published in
PNAS this week, has discovered the mechanism by which the parasitic
protozoa does this. Previous studies had shown that infected rodents
lacked the instinctive aversion to cat urine; instead they had a vague
preference for it. The work in this paper confirms those findings, and
also shows how it happens. "
