This magnified view reveals a pair of mating Schistosoma mansoni trematodes. Note that the thinner female is cradled inside the thicker male worm's gynecophoral canal.Created: 1973

This magnified view reveals a male Schistosoma mansoni trematode. Take a look at PHIL 11193, which depicts a mating pair of worms, where the thinner female is cradled inside the thicker male worm's gynecophoral canal.Created: 1973

This magnified view reveals a female Schistosoma mansoni trematode. Take a look at PHIL 11193, which depicts a male S. mansoni, and PHIL 11194, which depicts two mating worms. in which case you can see the thinner female cradled inside the thicker male worm's gynecophoral canal.Created: 1973

This photograph depicted the strobilocercus, or larval stage of an unidentified tapeworm of the order Cyclophyllidea. Families that are members of this order include Dipylidiidae, i.e., cucumber tapeworm and double-pore tapeworm, Hymenolepidadae, Taeniidae, i.e., livestock parasites, and Anoplocephalidae, i.e., horse and ruminant tapeworms.Created: 1973

Magnified 500X, this photomicrograph revealed the presence of a Fasciolopsis buski trematode egg that was found in an unstained formalin-preserved stool sample. F. buski are the largest intestinal flukes found parasitizing human beings. These flukes inhabit Asia and the Indian subcontinent, especially in areas where humans raise pigs, and consume freshwater plants.Clinical Features:Most infections are light and asymptomatic. In heavier infections, symptoms include diarrhea, abdominal pain, fever, ascites, anasarca and intestinal obstruction.Laboratory Diagnosis:Microscopic identification of eggs, or more rarely of the adult flukes, in the stool or vomitus is the basis of specific diagnosis. The eggs are indistinguishable from those of Fasciola hepatica.Created: 1973

Magnified 125X, this photomicrograph revealed the presence of two trematode eggs, a Fasciolopsis buski egg on the right, and an Echinostoma sp. egg seen of the left, which were found in an unstained formalin-preserved stool sample. Note how much larger the F. buski is compared to that of the Echinostoma sp. egg. F. buski trematodes are the largest intestinal flukes found parasitizing human beings. These flukes inhabit Asia and the Indian subcontinent, especially in areas where humans raise pigs, and consume freshwater plants.Created: 1973

This photomicrograph revealed some of the ultrastructural morphology exhibited by an adult cestode, Echinococcus granulosus, which had been found in a dog. E. granulosus causes what is known as cystic echinococcosis. As dogs and other canids are the only definitive hosts for Echinococcus, adults are not expected to be found in the human host. Adults range from 3mm - 6mm in length and usually consist of a scolex, and three proglottids. The third (terminal) proglottid is gravid, and is longer than wide, as can be seen in this instance. The scolex contains four suckers and a rostellum with 25 - 50 hooks.Created: 1975
