Gene expression profile of Clonorchis sinensis metacercariae
Parasitology Research, 2007Clonorchis sinensis develop through miracidium, sporocyst, redia, cercaria, and metacercaria stages before becoming egg-laying adult flukes. The authors undertook this analysis of gene expression profiles during developmental stages to increase our understanding of the biology of C. sinensis and of host-parasite relationships. From a C.

Excystment of the metacercaria of the trematode Mesocoelium monodi
International Journal for Parasitology, 1986Abstract Excystment of the metacercaria of the trematode Mesocoelium monodi. International Journal for Parasitology 16 : 237–239. The metacercaria of Mesocoelium monodi , an intestinal trematode parasite of Agama agama and Bufo regularis , excysted in 0.025% chymotrypsin, chicken and toad bile, human urine at 36°C, duodenal and intestinal ...

Lethal effect of ammonia on metacercariae of Clonorchis sinensis
Parasitology Research, 2003The effect of endogenous ammonia produced in dead fish or ammonia in ammonium bicarbonate solutions was evaluated on the viability of Clonorchis sinensis metacercariae. Viability was determined by worm recovery in rats infected with metacercariae exposed to ammonia in decaying fish or in vitro solutions.

The Culture of Diplostomum spathaceum Metacercariae on the Chick Chorioallantois
The Journal of Parasitology, 1986Metacercariae (2,828) obtained from the lens of naturally infected Aplodinotus grunniens were transplanted onto chorioallantoic membranes (CAM's) of 94 eggs (means 30/egg) 5 to 12 days old. Membranes were examined 2 to 8 days later and 381 flukes were recovered.

Ecology of Free-Living Metacercariae (Trematoda)
2015The 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, 2000Abstract 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, 1999The 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. Morphological features that may assist the matching of didymozoid metacercariae to adults are discussed. Those that may be of greatest

Isolation of Fasciola hepatica metacercariae by density gradients
Veterinary Parasitology, 1985Fasciola 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, 2018Paramphistomosis 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,
