Neuroparasitic Infections: Cestodes, Trematodes, and Protozoans [PDF]
Seminars in Neurology, 2005 Parasitic infection of the nervous system can produce a variety of symptoms and signs. Because symptoms of infection are often mild or nonspecific, diagnosis can be difficult. Familiarity with basic epidemiological characteristics and distinguishing radiographic findings can increase the likelihood of detection and proper treatment of parasitic ...

International Journal for Parasitology: Parasites and Wildlife, 2019 Infections of parasitic digenean trematode metacercariae may lead to a visually observable syndrome in fish commonly called black spot disease. While black spot has been noted from various locations throughout North America, patterns in prevalence across

The effects of parasitism and body length on positioning within wild fish shoals [PDF]
, 2002 The influence of body length and parasitism on the positioning behaviour of individuals in wild fish shoals was investigated by a novel means of capturing entire shoals of the banded killifish (Fundulus diaphanus, Lesueur) using a grid-net that ...

The effects of seasonality and parasitism on diet and habitat selection in the common periwinkle
Oikos, EarlyView.The common periwinkle Littorina littorea is an ecologically important grazer, known for its strong influence on algal communities and its role in structuring ecosystems. It serves as the first intermediate host for several trematode species in the Baltic Sea, especially for the fluke Cryptocotyle lingua.

Diagnosis of Human Trematode Infections
, 2014 Digenetic trematodes form a major group of human parasites, affecting a large number of humans, especially in endemic foci. Over 100 species have been reported infecting humans, including blood, lung, liver, and intestinal parasites. Traditionally, trematode infections have been diagnosed by parasitological methods based on the detection and the ...
