First record of Prosthogonimus cuneatus ( Prosthogonimidae ) from the Little Grebe , Tachybaptus ruficollis , in Korea
A trematode species belonging to the genus Prosthogonimus (family: Prosthogonimidae) was collected in August, 2004 from the bursa of Fabricius of a single Little Grebe, Tachybaptus ruficollis, caught in Chuncheon, Korea. Five specimens were collected in total and fluke morphology was examined under using a light microscope. The average parasite size was 5.6 × 3.2 mm (length × width; based on 4 ...
متن کاملThe development of isolated blastomeres in Bithynia tentaculata (Prosobranchia, Gastropoda).
The development of isolated blastomeres, separated at the first and second cleavage has been studied. After separation at the first cleavage, one half-embryo (CD) becomes swollen and balloon-like and develops adult organs such as eyes, tentacles, shell, operculum, etc. The other half (AB) is much more compact and never develops these adult structures. After separation on the alternate axis at t...
متن کاملThe development of Bithynia tentaculata (Prosobranchia, Gastropoda) after removal of the polar lobe.
The polar lobe of the egg of Bithynia, with a volume of less than 1 % of that of the egg, was surgically removed. Lobeless embryos form no mesentoblast cell nor mesoderm bands. They fail to establish bilateral symmetry and to form eyes, foot, operculum, shell, etc. They always differentiate larval head cells, ganglia, larval liver and mesenchyme and sometimes columnar epithelium, stomodeal entr...
متن کاملThe structure of a morphogenetic cytoplasm, present in the polar lobe of Bithynia tentaculata (Gastropoda, Prosobranchia).
In the first polar lobe of the egg of Bithynia tentaculata a cup-shaped mass of small vesicles is described, which fills the greater part of the lobe. It is named the 'vegetal body'. With methyl green-pyronin the vegetal body stains clearly, but after treatment with RNase no staining occurs, thus indicating the presence of RNA. The first polar lobe of Bithynia is of great importance for further...
متن کاملThe role of Bithynia tentaculata in the transmission of larval digeneans from a gravel pit in the Lower Thames Valley.
The freshwater snail, Bithynia tentaculata (Gastropoda: Prosobranchia), is frequently found in gravel pits and its role in the transmission of larval digeneans was assessed in one of these unstable water bodies from the Lower Thames Valley (UK) from June 1982 to December 1984. Eight species of cercarial and five species of metacercarial infections were reported from B. tentaculata, with up to 7...
