| | Ascaris (Site not responding. Last check: ) |
 | | The infective stage of Ascaris, is the egg containing an L2 larva, which is ingested by the host and hatches in the duodenum. |
 | | Secondary complications can arise with ascaris infections because sometimes, when the worms are undergoing this migration they appear to get lost and start wandering through other organs such as the brain, bile duct, pancreas or appendix. |
 | | Ascaris proteins are very immunogenic and people can become very sensitive to the worm and have strong allergic reactions. |
