    Study Notes

    Taeniasis and Cysticercosis

    • Caused by two parasites: Taenia solium (Pork tapeworm) and Taenia saginata (Beef tapeworm)

    Habitat and Definitive Host

    • Small intestine of humans (definitive host)

    Intermediate Host

    • Pigs (swine) for Taenia solium
    • Cattle (cows, sheep, camel) for Taenia saginata

    Infective Stage

    • Cysticercus cellulosa (Taeniasis) and eggs (Cysticercosis)
    • Cysticercus bovis for Taenia saginata

    Diagnostic Stage

    • Taeniasis: Taenia eggs and gravid segments in stool
    • Cysticercosis: Cysticercus in biopsy

    Clinical Picture

    • Taeniasis: Intestinal disturbances, abdominal discomfort, diarrhea, constipation, hunger pain, increase of appetite, loss of weight, anxiety, anemia, and intestinal obstruction
    • Cysticercosis: Infection of human and pigs tissue with the larval stage of T. solium, autoinfection, and ingestion of contaminated food or water

    Mode of Infection

    • Taeniasis: Eating imperfectly cooked beef or pork containing cysticercus
    • Cysticercosis: Autoinfection (egg from anus to mouth) or ingestion of contaminated food or water

    Lab Diagnosis

    • Taeniasis: Stool examination for Taenia eggs or gravid segments in feces
    • Cysticercosis: CT or MRI scan of brain, serology (ELISA), biopsy, and eosinophilia

    Prevention and Control

    • Taeniasis: Control of slaughterhouses and butchers, inspection of beef and pork for cysticercus, good cooking of meat (at least 56°C for 5 min) or freezing (at -10°C for 5-10 days)
    • Cysticercosis: Treatment of human excreta before use as animal manure, environmental sanitation, health education for personal hygiene and food hygiene

    Treatment

    • Taeniasis: Praziquantel (drug of choice)
    • Cysticercosis: Praziquantel, Albendazole, steroidal anti-inflammatory (for edema), and surgical removal of cysts
