ID#:12518
Description:This photomicrograph depicts the egg of a rat tapeworm, Hymenolepis diminuta, during its diagnostic stage. H. diminuta is a cestode frequently found in rodents, and infrequently seen in humans. See PHIL 3395 for a diagrammatic representation of this tapeworm’s lifecycle.
Eggs of Hymenolepis diminuta are passed out in the feces of the infected definitive host (rodents, humans). The mature eggs are ingested by an intermediate host (various arthropod adults or larvae), and oncospheres are released from the eggs and penetrate the intestinal wall of the host, which develop into cysticercoid larvae.
