Our body is like a fortress, guarding us from dirt and disease. Our skin surrounds us like a castle’s defensive walls, and burning acid in our stomach resists invaders. So how do these parasites sneak in?

Unwashed hands and undercooked meat are like Trojan horses, carrying Toxoplasma into our stomachs. The parasite’s waxy coating shields it from the stomach’s corrosive acid. It burrows into the gut wall, in search of shelter and food.
