Neurocysticercosis.

When human consumes contaminated pork containing cysticerci itresults in the transmission of viablecysticerci to the human small intestine, where by the action of bile and digestive enzymes, the scolexof a cysticercusevaginates and attaches to the intestinal wall. Proglottids multiply and the parasitebecomes a cestode that can be passed in the faeces as mature proglottids. The two main sources from which humans contact cysticercosisare ingestion of food contaminated with taeniid eggs and the faeco-oral route in individuals harbouringthe intestinal cestode. 3 Once in the digestive tract, the eggs loose their coat due to action of gastricand pancreatic enzymes and liberate hexacanth embryos or oncospheres. Aided by their hooklets,onospheres cross the intestinal wall and local venules, enter the systemic circulation and are carriedto different organs of the host.
