Currently, the general lifecycle of the whipworm is not completely understood. However, all whipworm species have a similar general lifecycle. Whipworm eggs are first ingested by the host. They eventually reach the duodenum of the small intestine, where the eggs ultimately hatch. The larvae from these eggs travel into the large intestine’s cecum. For about four weeks, the whipworms feed on blood vessels located within the cecum. Eventually, the whipworms leave the cecum and begin to lay thousands of eggs. These unembryonated eggs are then released from the host through feces. The process from egg ingestion to release takes around 12 weeks. The released eggs become embryonated in approximately nine to twenty-one days and are eventually ingested by another host.
