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

Clinical Features

  • 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

Differential Diagnosis

Helminth infections

Cestodes (Tapeworms)

Trematodes (Flukes)

Nematodes (Roundworms)

Diagnosis

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)
