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
- Often asymptommatic
Symptoms are more severe in those with immature or compromised immune systems
- Diarrhea
- Constipation
- Flatulence
- Hunger pain
- Weight loss
- Anal discomfort
Differential Diagnosis
Helminth infections
Cestodes (Tapeworms)
- Taenia saginata
- Taenia solium (Cysticercosis)
- Diphyllobothrium latum
- Hymenolepis nana
- Echinococcus granulosus
Trematodes (Flukes)
- Fasciola hepatica
- Fasciolopsis buski
- Opistorchis viverrini
- Schistosoma spp
- Chlonorchis sinensis
- Paragonimus spp.
Nematodes (Roundworms)
- Ascaris lumbricoides
- Enterobius vermicularis (Pinworm)
- Filarial worms
- Hookworm
- Necator americanus
- Ancylostoma duodenale
- Cutaneous larva migrans (Ancylostoma braziliense)
- Dracunculiasis
- Strongyloides stercoralis
- Trichuris trichiura (Whipworm)
- Anisakis
- Toxocara spp.
- Trichinosis
Evaluation
- Stool studies to detect ova and proglottids
- CBC may show eosinophilia
- CT/MRI/LP if concern for neurocysticercosis
Management
- Praziquantel - single dose of 5-10mg/kg
- Albendazole
- May give both albendazole and praziquantel for severe infections
