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.

Lymphocystis Disease in Endemic Aotearoa New Zealand Bully (Gobiomorphus cotidianus)

Journal of Fish Diseases, EarlyView.
ABSTRACT We detected lymphocystis disease virus (LCDV) for the first time in an Aotearoa New Zealand freshwater environment, from an individual common bully, toitoi, Gobiomorphus cotidianus (Eleotridae). Dinah's bully, Gobiomorphus dinae, and Kaharore bully, Gobiomorphus mataraerore, also exhibited gross nodular lesions on the fins but were not sampled.

Global Burden of Clinostomum complanatum in Freshwater Fish: A Systematic Review and Meta‐Analysis of Prevalence and Pathological Effect

Aquaculture, Fish and Fisheries, Volume 6, Issue 4, August 2026.
ABSTRACT Clinostomum complanatum infection is a trematode parasite infecting diverse freshwater fish hosts, causing pathological damage and economic losses. Despite its veterinary and public health importance, its global burden remains insufficiently quantified. This study aimed to assess the global burden of C.

Enemy release: loss of parasites in invasive freshwater bivalves Sinanodonta woodiana and Corbicula fluminea

Ecography, Volume 2026, Issue 8, August 2026.
Invasive freshwater bivalves harm native species, ecosystems and biodiversity, and incur economic costs. The enemy release hypothesis posits that invasive species are released from enemies during the invasion process, giving them a competitive advantage in the new environment.

Notocotylid Trematodes of Wild Birds in Türkiye: A Morphological Study With New Country Records

Veterinary Medicine and Science, Volume 12, Issue 4, July 2026.
This study presents the first comprehensive examination of notocotylid trematodes in wild aquatic birds from the Kızılırmak Delta, Turkey. Six trematode species belonging to the genera Notocotylus and Paramonostomum were identified through detailed morphological analysis. Four species (N. skrjabini, P. alveoelongatum, P.

Surface ultrastructure of Metagonimus miyatai metacercariae and adults [PDF]

The Korean Journal of Parasitology, 1998
A scanning electron microscopic study was performed to observe surface ultrastructures of excysted metacercariae and adults of Metagonimus miyatai. Metacercariae were collected from the scale of the pale chub (Zacco platypus), and adult flukes were harvested 1-4 weeks after infection to rats.

Digenean trematodes in Hungarian freshwater aquacultures

Food and Waterborne Parasitology, 2021
Occurrence of metacercariae of potentially zoonotic trematodes (Platyhelminthes: Digenea) in the musculature of common carp (Cyprinus carpio L. 1758) was monitored in four Hungarian aquacultures.

Growth and development of Fibricola seoulensis metacercariae in tadpoles

The Korean Journal of Parasitology, 1986
In order to observe the growth and development of Fibricola seoulensis metacercariae, the tadpoles of Rana nigromagulata were experimentally infected with the cercariae. The metacercariae of various developmental stages were recovered from the tadpoles after 2 to 65 days of infection.

Disease‐associated mortality drives reduction in Yukon River Chinook salmon escapement: A novel method for quantifying the negative impacts of ‘misfit’ parasites to improve fisheries management

Journal of Applied Ecology, Volume 63, Issue 6, June 2026.
Alaska Department of Fish and Game is implementing an annual monitoring program at the mouth of the Yukon River where our model will estimate the proportion of Chinook salmon at risk from parasite‐induced mortality to inform annual management. Moreover, the model is broadly applicable to other fungal‐like and myxozoan parasites of conservation concern,
