Habits Quote by Mary Roach
““Khoruts gave me a memorable example of how behavior can be covertly manipulated by microorganisms. The parasite Toxoplasma infects rats but needs to make its way into a cat’s gut to reproduce. The parasite’s strategy for achieving this goal is to alter the rat brain such that the rodent is now attracted to cat urine. Rat walks right up to cat, gets killed, eaten. If you saw the events unfold, Khoruts continued, you’d scratch your head and go, What is wrong with that rat? Then he smiled. “Do you think Republicans have different flora?””
About This Quote
Source Interview: “The Microbe’s Influence on Behavior” with Khoruts, 2015
Microorganisms can subtly hijack host behavior to further their own life cycles, exemplified by Toxoplasma making rats attracted to cat urine, raising questions about hidden biological influences on human politics.
In simple terms: Parasites can change host actions for their benefit.
