Ecology of Free-Living Metacercariae (Trematoda)

2015
The presence of trematodes with a free-living metacercarial stage is a common feature of most habitats and includes important species such as Fasciola hepatica, Parorchis acanthus and Zygocotyle lunata. These trematodes encyst on the surface of an animal or plant that can act as a transport host, which form the diet of the target definitive host ...

Ultrastructure of the tegument of the metacercaria of Timoniella imbutiforme

Journal of Helminthology, 2000
Abstract The spinous body tegument of the metacercaria of Timoniella imbutiforme (Molin, 1859) is described in detail and found to comprise an outer tegumental syncytium connected to subjacently situated subtegumentary ‘cells’. There are four types of secretory bodies in the

Identification and maturation of the metacercaria of Indodidymozoon pearsoni

Journal of Helminthology, 1999
The metacercaria of Indodidymozoon pearsoni (Digenea: Didymozoidae) is identified by DNA sequencing of second internal transcribed spacer (ITS2) ribosomal DNA and described. Its development into the adult is documented.

Isolation of Fasciola hepatica metacercariae by density gradients

Veterinary Parasitology, 1985
Fasciola hepatica metacercariae were purified in high yield, removing contaminating cyst walls and plant material by step gradients consisting of 10 ml of 60% Percoll (density = 1.08 g ml-1) and 10 ml of 50% Metrizamide (density = 1.25 g ml-1). Greater than 90% of the metacercariae applied to the density gradients were recovered.

Paramphistomosis of Ruminants: The Role of Free-Living Metacercariae

Trends in Parasitology, 2018
Paramphistomosis is a parasitic disease of farmed ruminants caused by paramphistomum trematode infections of the host rumen (secondary stomach chamber) which result in widespread clinical symptoms or death. Commonly known as rumen or stomach flukes, the prevalence of these trematodes in livestock populations has substantially increased in recent years,

Some Lecithodendriid Metacercariae from Indiana and Michigan

The Journal of Parasitology, 1960
In a review article on arthropods as intermediate hosts of worm parasites, M. C. Hall (1929) listed six members of the trematode family Lecithodendriidae as having their metacercarial stage in various aquatic insects, including members of the orders Diptera, Odonata, Plecoptera, Ephemeroptera, Trichoptera, and Coleoptera. Since that time, Brown (1933),

A New Trematode Metacercaria from the Eyes of Trout

Nature, 1953
SEVERAL workers1–4 have reported the occurrence of eye metacercariae from various British freshwater fishes, and all have regarded their specimens as Diplostomum volvens. This, as described originally by Nordmann (1832) and reported later by various workers, has an oral sucker much smaller than the ventral, and its lateral adhesive organs are never in ...

[Metacercaria in the invertebrates of the Madras coast].

Angewandte Parasitologie, 1976
In planktonic and benthic invertebrates of the Madras coast, Bay of Bengal, six Metacercariae have been reported. Four species are from planktonic intermediate hosts. They were found in Ctenophora, Leptomedusa and the gastropod Janthina. They belong to the Hemiurate, Fellodistomatidae and Lepocreadiidae. Two species are from benthic molluscs and belong
