Examining Cysticercosis Statements

This section analyzes the provided statements regarding cysticercosis to identify the correct one.

Statement Analysis

• Statement 1: The causative agent is Echinococcus granulosus.

  Analysis: This statement is incorrect. Echinococcus granulosus causes echinococcosis. Cysticercosis is caused by the larval stage of Taenia solium (pork tapeworm).

• Statement 2: The definitive host is man.

  Analysis: This statement is nuanced and generally considered incorrect in the context of human cysticercosis. While humans are the definitive host for the adult Taenia solium tapeworm, they act as the intermediate host when infected with the larval cysts that cause cysticercosis.

• Statement 3: Human cysticercosis is transmitted by the ingestion of ova.

  Analysis: This statement is true. Cysticercosis occurs when humans ingest Taenia solium eggs (ova), typically through fecal-oral contamination. These eggs develop into larval cysts (cysticerci) in various body tissues.

• Statement 4: Levamisole is the treatment of choice.

  Analysis: This statement is incorrect. Standard treatments for cysticercosis typically include praziquantel or albendazole, not Levamisole.

Conclusion

Based on the analysis, the only true statement regarding human cysticercosis is that it is transmitted by the ingestion of ova.
