Why is cysticercosis dangerous?

Cysticercosis is the invasion of human tissues by cysticercus cellulosae, the larval stage of T. solium (man acts as intermediate host).

Cosmopolitan especially in pig raising countries.

 

     
 

Ingestion of eggs of T. solium by one of the following ways:

This is called Heteroinfection

• Contaminated food or drink with eggs

This is called External autoinfection

• Hand to mouth infection in a patient having adult worms in his intestine

This is called Internal autoinfection

• In a patient having adult worms in his intestine, some detached segments may ascend by antiperistaltic movements to the stomach then descend again to the intestine where they hatch and cause cysticercosis

In the small intestine, onchosphere hatches, penetrates intestinal mucosa to the circulation to various tissues and changes into cysticercus cellulosae.
