Larval trematode populations and host-parasite interactions in Cerithidea Californica
… to determine the fecundity of the parasitic trematode species in its gonad. Five species of trematodes are studied (Cloacitrema michiganensis, Euhaplorchis californiensis, Parorchis acanthus, Himasthia rhigedana, and Acanthoraryphium sp.). Their fecundity is determined by direct counts of …

Effects of Atrazine and Metolachlor on Snails, Tadpoles, and Their Trematode Parasites
… I examined changes in survivorship when trematode parasites (Echinostoma trivolvis) and their first intermediate host, Planorbella trivolvis snails, were exposed to a low concentration (10 ppb: 15 ppb) and high concentration (85 ppb: 100 ppb) mixture of atrazine and metolachlor, …

<em>In Vitro Cultivation</em> of the Microphallid Trematode <em>Gynaecotyla Adunca</em>
… study the genetics and the biology of parasites. Trematodes have complex life cycles with multiple hosts which makes them difficult to grow <em>in vitro</em>. However, microphallid trematodes are excellent candidates for parasite <em>in vitro</em> cultivation because they are short lived and …

The reciprocal influence of trematode parasites and malathion on developing pickerel frogs (Rana palustris)
… 48-hr toxicity tests to examine effect of trematode parasite, Echinostoma trivolvis, infection (0, 10, or 30 cercaria) on the susceptibility of pickerel frog tadpoles to the widely used organophosphate insecticide malathion. LC50 values ranged from 16.5 – 17.4 mg/L, within the range …

Trematode parasites of the mudsnail Ilyanassa obsoleta: An analysis of parasite communities at different scales
… examines the ecological factors that shape trematode parasite communities of mudsnail Ilyanassa obsoleta at three different spatial scales. Nine species of trematode which obligately infect I. obsoleta during larval stages but use numerous estuarine species as second intermediate and …

Trematode Communities of the Appalachian Stream Snail, Elimia proxima: the Importance of Scale in Parasite Ecology Research
… may respond to future disturbance. Digenean trematodes (Platyhelminthes: Trematoda) are parasitic flatworms with complex, multi-host life cycles that include snail first-intermediate hosts and vertebrate definitive hosts. Trematodes cause numerous diseases of humans (e.g. schistosomiasis) and …

Life cycle studies on Stephanostomum pacificum, a new species of trematode, from the Pacific Marine Station area
… of a study on the life cycle of a member of the trematode family Acanthooolpidae, genus Stephanostomum Looss, 1899, which was carried on during the summers of 1948, 1949, 1951, and the winter of 1948-49 at the Marine Station of the College or the Pacific at Dillon Beach, California. Only one …
