In the intestine, the parasite will move into the abdomen and commonly into the lungs. In the lung, the parasites encyst and cross fertilize each other. The cyst eventually ruptures in the lungs and the eggs may be coughed up or swallowed and excreted in the feces. An egg landing in fresh water hatches and releases a ciliated miracidium.
The earliest known parasite in a human was eggs of the lung fluke found in fossilized feces in northern Chile and is estimated to be from around 5900 BC. There are also claims of hookworm eggs from around 5000 BC in Brazil and large roundworm eggs from around 2330 BC in Peru.
The eggs hatch into first-stage larvae, which travel in the bloodstream to the lungs, where they travel up the respiratory tract, are swallowed, and then pass out of the body in the mucus coating of fecal pellets. [4] [7] Gastropods such as snails and slugs feed upon the mucus coating of the fecal pellets and ingest the larvae.
