Ultrastructural studies on the surface of Paragonimus westermani metacercaria

The Korean Journal of Parasitology, 1987
The present study was undertaken to demonstrate the surface structure of Paragonimus westermani metacercaria in Korea with special reference to the distribution of sensory papillae. Metacercariae were isolated from crayfish, one of the second intermediate host of P.

Brain‐Encysting Trematodes Increase the Frequency but Reduce the Repeatability of Surfacing Behaviour in Mottled Triplefin

Ethology, Volume 131, Issue 11, Page 239-249, November 2025.
In Otago Harbour, New Zealand, the trophically transmitted trematode Cardiocephaloides ovicorpus infects the brain of a population of mottled triplefin (Forsterygion capito) with high prevalence and intensity. Behavioural tests revealed that the infection intensity was significantly positively correlated with surfacing frequency, and repeatability of ...

The Effect of Climate Change on Emergence and Evolution of Zoonotic Diseases in Asia

Zoonoses and Public Health, Volume 72, Issue 7, Page 587-611, November 2025.
ABSTRACT As the climate of Asia changes under the influence of global warming, the incidence and spatial distribution of known zoonoses will evolve, and new zoonoses are expected to emerge as a result of greater exposure to organisms which currently occur only in wildlife.

Transmission patterns of Fasciola hepatica to ruminants in Sweden [PDF]

, 2014
Transmission patterns of Fasciola hepatica were investigated on beef cattle (n = 3) and sheep (n = 3) farms in Sweden between 2011 and 2012. The dynamics of fluke infection, particularly estimated time of infection, were screened each grazing season by ...

Trematode Infection Prevalence Increases With Snail Richness: Observations From a 4‐Year Study of Snail–Trematode Interactions

Ecology and Evolution, Volume 15, Issue 10, October 2025.
We find that higher snail richness correlated with increased overall and generalist trematode infections, while specialist infections showed a similar but nonsignificant trend. The study also highlighted potential host‐switching events and the impact of long‐term sampling on parasite communities, emphasizing the need for continued monitoring of host ...

Infection with Clonorchis sinensis (Cobbold, 1875) Metacercariae in Fish from the East Lake of Wuhan: Freshwater Fish in Urban Lakes May Act as Infection Sources of Liver Fluke

Microorganisms
The liver fluke disease caused by Clonorchis sinensis is one of the most serious food-borne parasitic diseases in China. Many freshwater fish and shrimps can be infected with C.

In vitro cultivation of Gymnophalloides seoi metacercariae (Digenea:Gymnophallidae)

The Korean Journal of Parasitology, 1997
Gymnophalloides seoi is a human intestinal trematode prevalent on southwestern islands in Korea. In the present study, we investigated whether G. seoi metacercariae can grow and develop into adults by in vitro cultivation. The metacercariae were obtained from naturally infected oysters, and cultured in vitro for 5 days under three conditions; 37 ...

Surface ultrastructure of Metagonimus takahashii metacercariae and adults [PDF]

The Korean Journal of Parasitology, 2000
A scanning electron microscopic study was performed on the surface ultrastructure of metacercariae and adults of Metagonimus takahashii. Metacercariae were collected from the scale of crucian carp (Carassius auratus), and adult flukes were harvested 1-4 weeks after infection to rats.
