Metacercariae of Acanthoparyphium marilae Yamaguti, 1934 (Digenea: Echinostomatidae) were discovered in an intertidal clam, Mactra veneriformis, in a southwestern coastal area of the Republic of Korea. A total of 128 metacercariae were detected from 10 clams examined. They were round, 320 �m in average diameter, with 23 collar ...

Abstract The tegumental ultrastructure of juvenile and adult Acanthoparyphium tyosenense (Digenea: Echinostomatidae) was observed by scanning electron microscopy. One- to 3-day-old juveniles and 10-day-old adults were harvested from chicks experimentally fed metacercariae from a bivalve, Mactra veneriformis. The juvenile worms were minute, curved ...

The upper respiratory tracts of 534 wild anatids representing 20 species, shot during the 1976, 1977 and 1978 hunting seasons, were examined for Typhlocoelum cucumerinum (Rudolphi, 1809). Typhlocoelum cucumerinum cymbium (Diesing, 1850) were recovered from Anas platyrhynchos, Anas rubripes, Anas acuta, Anas discors and Anas crecca. The maximum prevalence (16.7%) and intensity of infection (1.6) ...

372 Plasma Yolk Precursor Dynamics during Egg Production by Female Greater Scaup (Aythya marila: Anseriformes, Aythya marila). We also evaluated VTG and total VLDL-TG as physiological indices of reproductive: Anseriformes, Aythya marila; hereafter, scaup), a species that incurs particularly high energetic
Parasitic fauna of birds connected with water environment, including digeneans, is relatively well researched in Poland. The exception, however, is West Pomerania, where those birds were not frequent objects of parasitological research until recently. The purpose of this work is to determine the taxonomic structure of the Digenea, parasitising wild ducks living in West ...

We experimentally investigated the interactions between two parasites known to manipulate their host's phenotype, the trematodes Acanthoparyphium sp. and Curtuteria australis, which infect the cockle Austrovenus stutchburyi. The larval stages of both species encyst within the tissue of the bivalve's muscular foot, with a preference for the tip of the foot. As more individuals ...
