Euparyphium albuferensis and Echinostoma friedi cercarial infectivity to four species of sympatric snails was examined under single- or multiple-choice laboratory conditions to show the level of parasite-snail host compatibility. Radix peregra, Lymnaeafuscus, Physella acuta and Gyraulus chinensis act as second intermediate hosts of both parasite species although different cercarial transmission...

The parasite faunas of the black stilt (Himantopus novaezelandiae) and the pied stilt (H. h. leucocephalus ) in New Zealand were investigated. The alimentary tracts of eleven black stilts, and three entire pied stilts were examined for the presence of parasites, particularly helminths, and a number of carcasses were surveyed for the presence of ectoparasites. Faecal samples were taken from capt...

To funistic survey of the cercariae of Melanoides tuberulata (fresh water snail) 1540 M.tuberculata were collected from various streams, swamps, ditches and canals in the central area of Khouzestan province in the south west of Iran. Infected snails, 46 (2.9%), were isolated and cercariae were obtained by emerging or crushing methods and then measuring and drawing were made from specimens. In s...
