Machiavellian Microbes

November 19, 2024·19 min·1 clip
Toxoplasma makes infected male rodents sexually aroused by the smell of cat urine, luring them to their deaths so the parasite can reproduce.
This episode explores the bizarre case of Jack and Donna Wright, who hoarded a world record 689 cats, and investigates the shocking scientific hypothesis that their behavior might have been influenced by a brain-altering parasite, Toxoplasma gondii. The narrative delves into how this 'Machiavellian microbe' manipulates the behavior of rodents, wolves, and potentially humans by hijacking brain chemistry.
