In vitro excystment of the metacercariae of Ribeiroia ondatrae
Parasitology Research, 2005In vitro excystation studies were done on the metacercarial cysts of Ribeiroia ondatrae obtained from naturally infected leopard frogs, Rana pipiens. Studies were done in Petri dish cultures in various media maintained at 41 degrees C. The media consisted of 0.5% trypsin-0.5% bile salts in Earle's balanced salt solution at pH 7.8 (TB), 1% acid pepsin ...

Digenean Metacercariae Parasitic in a Staurozoan Cnidarian
Zoological Science, 2022I report digenean metacercariae from Staurozoa, which were not previously known as digenean hosts. The host species, Haliclystus tenuis Kishinouye, 1910, was collected from algae in Oshoro Bay, Hokkaido, Japan, and contained metacercariae in the mesoglea. The metacercariae were encysted; cysts were oval, 93 µm long by 64 µm wide in one live individual.

Studies on the viability of metacercariae of Fasciola gigantica
Journal of Helminthology, 1999The viability of metacercariae of Fasciola gigantica was tested by in vitro and in vivo methods. In vitro testing was based upon the motility of juvenile flukes within the inner cyst as examined under the light microscope. In vivo testing was undertaken through experimental infections of rabbits (two groups) and natural definitive hosts, lambs (one ...

In Vitro Excystation ofParagonimus heterotremusMetacercariae
Journal of Parasitology, 2001In vitro excystation studies were carried out on the metacercariae cysts of Paragonimus heterotremus obtained from naturally infected crabs Potamon spp. The effects of elastase, trypsin, trypsin-dog bile, trypsin-bile salt, and dithiothreitol (DTT) were examined. The trypsin-dog bile medium stimulated maximum excystation.

Cercariae and metacercariae of Stephanostomumcloacum (Trematoda: Acanthocolpidae)
International Journal for Parasitology, 1993Cercariae and metacercariae of the acanthocolpid trematode, Stephanostomum cloacum (Srivastava, 1938) are described and illustrated, based on material collected from Chilka Lake, a brackish water lagoon. Natural infections with the cercariae were found in the snail, Nassarius orissaensis and with the metacercariae in the bivalve, Modiolus undulatus ...

Bile-induced genes in Clonorchis sinensis metacercariae
Parasitology Research, 2008Bile stimulates many intestinal parasites, and newly excysted juvenile Clonorchis sinensis (CsNEJ) responds chemotactically to bile and matures in the bile duct. In this study, using annealing control primer-based polymerase chain reaction (PCR), 16 differentially expressed genes (DEGs) were found to be upregulated in C.

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.
