 The life cycle, because how are these parasites? How do we get these parasites? When this parasite, when this cyst, this is what we found at the effluent, this cyst. This cyst can live in the water, it takes a long time, three years. Some cysts of parasites take ten years before they can get destroyed. But when environmental temperature, like lower than 100 degrees centigrade, they are still resistant. So this, when this cyst has been dropped in the water, they take a long time. And when the animal, like fish, that filter water, like mussel, they take in this cyst. And when you eat them without properly cooking them, you become infected. If you take this water with the cyst and you water your vegetable with it, the cyst can live in this salad. It can stay there for a long time. And when you take the vegetable to eat without properly washing again, you have taken some. And when you take it in your body, what happened? This cyst, they undergo fusion, a kind of asexual reproduction, you call it cisogony, multiply in their millions. When they are in the stomach, that is the best environment they are. And they can multiply in thousands. So when they multiply, they form the sexual and the asexual states. And then when they are mature, they are being deposited again into the environment. That is how the life cycles are.
