Geographic Distribution/Epidemiology

Especially common in Latin America and in countries with pig farms (e.g., China, Africa, India); in some countries these cysticercus are diagnosed in 2–3 % of all autopsies. In Europe only rare cases occur, in those countries with intense meat inspection (e.g., Germany).

Morphology/Life Cycle

The so-called Cysticercus cellulosae represents the larval stage of the tapeworm Taenia solium, which parasitizes inside the intestine of humans. Normally the Cysticercus cellulosaeoccurs in tissues of the intermediate host pig (wild and farmed ones). If humans ingest eggs of this tapeworm, they may become intermediate (paratenic) hosts, too. Since the larva (oncosphaera) is able to hatch inside the human intestine, it enters via bloodstream many organs, where the cysticercus is finally formed. The cysticercus grows up to a fluid-filled, translucent bladder of about...
