Viability of Metagonimus romanicus (Ciurea, 1915) metacercariae after physico-chemical treatments

Food and Waterborne Parasitology
Digenean (Heterophyidae) trematodes include several zoonotic species such as the genus Metagonimus (Katsurada, 1912). Metagonimus romanicus (Ciurea, 1915) is a species widely distributed in Europe, whose metacercariae can be found on cyprinoids from the ...

Proteomic analysis of Ascocotyle longa (Trematoda: Heterophyidae) metacercariae

Molecular and Biochemical Parasitology, 2020
Ascocotyle longa is parasitic trematode with wide distribution throughout America, Europe, Africa, and Middle East. Despite the fact that this fish-borne pathogen has been considered an agent of human heterophyiasis in Brazil, the molecules involved in the host-parasite interaction remain unknown.

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.

Parasitism by Sphincterodiplostomum musculosum (Digenea, Diplostomidae) metacercariae in the eyes of Steindachnerina insculpta (Characiformes, Curimatidae)

Revista Brasileira de Parasitologia Veterinária
New occurrences and effects of parasitism by metacercariae in fish eyes have recently been discussed in many studies. The aim of the present study was to evaluate the infection levels of the eye flukes Sphincterodiplostomum musculosumDubois, 1936 ...

EXCYSTMENT OF CRYPTOCOTYLE LINGUA METACERCARIAE

The Biological Bulletin, 1966
1. The excystment of C. lingua metacercariae is mediated by the action of digestive enzymes. The same sequence of enzyme solutions as that met with in the host's digestive tract is required.2. Reducing and surface-active agents, and a carbon dioxide atmosphere enhance excystment.3.

Trematode infection buffers heat stress in blue mussels Mytilus edulis: The role of heat shock proteins

Journal of Animal Ecology, EarlyView.
The study shows that parasite infection changes heat shock protein expression and can increase heat tolerance in blue mussels. By separating parasite and temperature effects, the results suggest that infection may improve survival during heat stress, highlighting important parasite–host interactions for climate change resilience. Abstract The influence

Prevalence and species identification of trematode metacercariae in Qiqihar, Northeast China

Frontiers in Microbiology
Fishborne trematode (FBT) is an important group of parasites that are endemic worldwide to a certain extent. However, despite the epidemiological significance, the species and phylogenetic evolution characteristics of FBT metacercariae have not been well

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 ...

Pathological and Epidemiological Assessment of Trematode Burden in Ruminants From Central Ethiopia

Veterinary Medicine and Science, Volume 12, Issue 2, March 2026.
• Trematode infections were highly prevalent (49.22%) among ruminants in central Ethiopia, with fasciolosis (32.42%) and paramphistomosis (16.80%) strongly associated with poor body condition and specific geographic origins. • Histopathological and haematological analyses revealed severe liver and intestinal damage, anaemia, and elevated liver enzymes,
