Studies on the life-cycle of Uvulifer iruvettiensis sp. nov. (Digenea: Diplostomidae)
Acta Parasitologica, 2013AbstractThe life-cycle stages of a new species of Uvulifer, U. iruvettiensis sp. nov. infecting the white-throated kingfisher Halcyon smyrnensis (Linnaeus) in Kerala, India are described. The new species is described in detail, and compared with its related species.

Passerine Birds as Experimental Hosts for Posthodiplostomum minimum (Trematoda: Diplostomidae)
The Journal of Parasitology, 1961Posthodiplostomum minimum (MacCallum, 1921) Dubois, 1936, is a common strigeoid trematode parasitizing several species of herons. Metacercariae of this species, formerly known as Neascus van cleavei (Agersborg), occur in a wide variety of fresh-water fishes, where they invade the liver, spleen, opisthonephroi, mesenteries, and pericardium.

Toxicity of cadmium and zinc to Diplostomum spathaceum (Trematoda: Diplostomidae) cercarial survival
International Journal for Parasitology, 2001The toxicity of cadmium and zinc at concentrations ranging from 0.1 to 10000 microg/l was investigated with cercariae of Diplostomum spathaceum at three temperatures (12, 20, 25 degrees C) and three levels of water hardness (distilled water, soft water, hard water).

Using TEM techniques, 13 types of sensory endings were revealed on the body and tail of cercariae of D. pseudospathaceum. They differ in the presence or absences of cilia, number of cilia, number of electron-dense rings, basal body type and collar shape.

Archives of Environmental Contamination and Toxicology, 2002
The toxicity of cadmium and zinc mixtures at concentrations ranging from 0.1 to 10,000 microg/L was investigated against the survival of the free-living cercarial stage of the parasitic fluke Diplostomum spathaceum. Cercariae were exposed to metal mixtures of equal concentration, metal mixtures of unequal concentration, and low-dose pretreatment ...

Laboratory experiments were carried out to examine the impact of mercury and chromium upon survival of Diplostomum sp. cercariae. Freshly emerged cercariae were exposed to solutions of either mercury, at concentrations ranging between 0.1 and 100 microg/l, or chromium at concentrations from 2 microg/l to 2 mg/l. The mortality patterns and mean survival

The sporocyst wall of the daughter sporocyst of Diplostomum pseudospathaceum is composed of many elements. It is covered by a syncytial layer of cytoplasm connected to sunken nucleated perikarya (cytons), lying underneath the outer-circular and the inner longitudinal muscle layers.

[Enzyme activity of metacercariae in the genus Diplostomum (Trematoda, Diplostomidae)].
Parazitologiia, 1984Studies were conducted of the content of ferments with which metacercariae of trematodes of the genus Diplostomum affect the tissues of the host's crystalline lens. The following ferments were found in exudates of metacercariae: pepsin, cathepsin, hyaluronidase and lipase. Their activity depends to a great extent on temperature. Considerable changes in

The article provides the description of the Diplostomum rutili Razmashkin, 1969 cercariae from spontaneously infected crimean population mollusks Lymnaea stagnalis Linnaeus, 1758 and the metacercariae experimentally obtained in the juveniles of the roach, Rutilus rutilus Linnaeus, 1758. Some distinguishing features of the cercaria are noted.
