Histochemistry and Ultrastructure of the Metacercarial Cysts of Blackspot Trematodes Uvulifer ambloplitis and Neascus pyriformis

Journal of Parasitology, 1991
Cysts of Uvulifer ambloplitis from green sunfish, Lepomis cyanellus, and Neascus pyriformis from red shiners, Notropis lutrensis, were studied with light-level histochemistry and scanning and transmission electron microscopy. Cysts of both species are bilayered, consisting of an outer host capsule and an inner parasite cyst; the space between these ...

A New Strigeid Larva, Neascus wardi

Journal of Parasitology, 1928
Very few of the papers concerning the family Strigeidae (Holostomidae) deal with the historical background. Most of them treat the species and do not discuss the taxonomic relations. Goeze (1782) was the first to describe a species now listed as a member of this family, viz. Henmistomum alatum, from a fox's intestine, as a Planarian.

Neascus Infestation of Black-Head, Blunt-Nosed, and other Forage Minnows

Progressive Fish-Culturist, 1940
Abstract Black-head, blunt-nosed, and other minnows were found infested with encysted flatworms in ponds at Leetown, West Virginia. The mortality in a 2.2-acre pond stocked with 100,000 black-head minnows was about 250 per day during four weeks of observation. Heavy infestations caused sterility in the minnows.

Persistence of infection by metacercariae of Apophallus sp., Neascus sp., and Nanophyetus salmincola plus two myxozoans (Myxobolus insidiosus and Myxobolus fryeri) in coho salmon Oncorhynchus kisutch.

Journal of Parasitology, 2010
We evaluated the ability of 5 muscle- or skin-dwelling parasites to persist in naturally infected coho salmon, Oncorhynchus kisutch, from the West Fork Smith River, Oregon, by holding them in captivity from late summer to early spring (parr stage to the typical time of smoltification).

Estimates of daily mortality from a neascus trematode in age-0 shortnose sucker (Chasmistes brevirostris) and the potential impact of avian predation

Environmental Biology of Fishes, 2013
Parasites may be an important component of early life mortality in fishes, but assigning part of total mortality to parasites is difficult. The Chapman-Robson mortality estimator is a robust and potentially valuable way to quantify the added mortality of parasites when age data are available.

Incidence of Neascus rhinichthysi (Trematoda: Diplostomatidae) on Longnose Dace, Rhinichthys cataractae (Pisces: Cyprinidae), Related to Fish Size and Capture Location

Transactions of the American Fisheries Society, 1977
Abstract Longnose dace, Rhinichthys cataractae, collected from the Tongue River and Goose Creek near Sheridan, Wyoming, were analyzed for the incidence of the trematode parasite, Neascus rhinichthysi, based upon fish size and sample location. Both incidence and mean number of metacercarial cysts were significantly greater in the fish collected from ...
