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
Signs and Symptoms
- symptoms include diarrhea, constipation, flatulence, hunger pain, weight loss, and appendicitis, as well as discomfort of the proglottids crawling out of the anus
- symptoms are more severe in those with immature or compromised immune systems
Treatment
- praziquantel, single dose of 5-10 mg/kg (2)
- niclosamide outside the U.S. (single dose of 2 gm or 50 mg/kg for pediatrics) (2)
