Background
- also known as the beef tapeworm
- humans are the only known definitive host, cattle are intermediate hosts
Transmission
- transmitted by ingesting undercooked beef containing the tapeworm larvae
- larvae mature in the human intestines and the mature tapeworm attaches to the intestinal walls to ingest nutrients from the host
- mature tapeworms release gravid proglottids in the stool which release eggs into the stool, which can remain active in sewage for several weeks
