Taeniasis

(with a little bit of Cysticercosis)

 

Taeniasis is a type of diseases caused by the cestode Taenia tapeworms. Humans acquire this infection by consuming larval cysts in raw or undercooked meats of infected animals. While there are many species of Taenia tapeworms, humans serve as the definitive hosts for only two species: Taenia saginata (beef tapeworm) and Taenia solium (pork tapeworm). The larvae from the infected meats develop into large tapeworms in the human intestine. Adult tapeworms then attach themselves to the mucosa of the small intestine and absorb nutrients from their host.

Taeniasis with T. saginata and T. solium infections are usually asymptomatic or relatively mild in symptoms. However, individuals who ingest T. solium eggs may develop a serious tissue infection called cysticercosis. Cysticercosis (or bladder worms) infect the brain and central nervous systems. It may cause causes epileptic seizures, blindness, and sudden death.

The exact prevalence of tapeworm infections are not exactly known. But epidemiologists estimate that over 100 million people may be infected with T. saginata and/or T. solium. Taeniasis is very common in regions of poor sanitation and hygiene.
