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 are more severe in those with immature or compromised immune systems

Differential Diagnosis

Helminth infections

Cestodes (Tapeworms)

Trematodes (Flukes)

Nematodes (Roundworms)
