Mammals are the
intermediate hosts and
snakes are the
definitive hosts. Once the larva hatches from the egg, it penetrates the duodenal mucosa of the host. The process from swallowing the egg to complete entry into the host takes about an hour. After reaching the duodenal mucosa, the larvae migrate to the abdominal cavity, where they spend about a week until they are encapsulated in the host tissue. Over a three-month period, the parasite molts five additional times, increasing in size and developing segmentation. The sex of the parasite becomes identifiable after the fifth molt. Upon completing the sixth molt, the nymphs become encapsulated and enter a dormant state. If a snake eats the nymph, the nymph loses its dormancy and quickly enters the intestinal wall of the snake where it travels to the lungs. They then feed on the blood and tissue fluids in the lungs until they reach maturity. == Disease ==
