Studies on the biology of Plagiorchis elegans (Rudolphi, 1802), (Trematoda: Digenea) in its mammalian and molluscan hosts
The taxonomy of the genus Plagiorchis Luhe, 1899 is reviewed with particular reference to the species P.elegans (Rud. 1802) and a list of Plagiorchia species previously recorded in Britain is given. The life cycle was initially established using Lymnaea stagnalis, Chironomus sp.larvae and LACA …

Ritmos biológicos na emergência de Cercárias de Shistosoma mansoni Sambon, 1907 (Platyhelminthes: Digenea) em infecções mono e plurimiracidianas de Biomphalaria glabrata (Say, 1818) (Mollusca: Gastropoda)
This work aims to study the daily rhythm of emergence of S. mansoni cercariae in mono - and plurimiracidial infections of B. glabrata. For this purpose the emergence at daytime and nighttime and its peaks were compared through a chronobiological methodology. For the tests,19 and 37 specimens of …

Marine Cercariae from Cerithidea Pliculosa Menke from Dauphin Isalnd, Alabama; Life Cycles of Heterophyid and Opisthorchiid Digenea from Cerithidea Swainson from the Eastern Gulf of Mexico
Horn snails of the genus Cerithidea Swainson (1840) are represented in North America by four species. They are: Cerithidea costata (da Costa, 1778), found in South Florida and in the West Indies; Cerithidea californica (Haldeman, 1840), from Bolinas Bay, California to the Gulf of California; …

Aspects of stress with particular reference to mytilid mussels and their parasites
Eight new species of digenea were found in a survey of Aulacomya ater, Choromytilus meridiana/is, Perna perna and Mytilus galloprovincialis. Metacercaria notobucephala sp. nov., a bucephalid from Choromytilus has locality-specific prevalences ranging from 0.23% to 4.46%. It is a severe reproductive …
