Taenia spp.

Cysticercosis results from ingesting T. solium eggs. Neurocysticercosis is the most common cause of seizure disorder in South and Central America.

Passing Taenia eggs in stool is indicative of tapeworm infection from eating meat with encysted larvae. Individuals passing T. solium eggs may infect themselves and others, causing outbreaks of cysticercosis.

Eggs of Echinococcus spp are indistinguishable from those ofTaenia spp., but humans are intermediate hosts and do not pass Echinococcus eggs in stool.
