Parasites, including macroparasites, protists, fungi, bacteria and viruses, can impose a
heavy burden upon host animals. However, hosts are not without defences. One aspect of …

Given their sheer cumulative biomass and ubiquitous presence, parasites are increasingly
recognized as essential components of most food webs. Beyond their influence as …

Parasites have evolved independently in numerous animal lineages, and they now make up
a considerable proportion of the biodiversity of life. Not only do they impact humans and …

Current aquatic farming practices and the species that are grown worldwide are
extraordinarily varied and reflect the diversity of habitats, ecological niches and biological …

We examined the parasite-induced cataract formation in rainbow trout (Oncorhynchus
mykiss) using slit-lamp microscopy to determine the relationship between cataract intensity …

This paper examines the efficiency of acquired resistance in protecting the fish host, rainbow
trout (Oncorhynchus mykiss), against the trematode parasite Diplostomum spathaceum, and …

Environmental stress has been suggested to increase host susceptibility to infections and
reduce host ability to resist parasite growth and reproduction, thus benefiting parasites. This …

The diversity and abundance of parasites vary widely among populations of the same host
species. These infection parameters are, to some extent, determined by characteristics of the …

Digeneans (Platyhelminthes: Trematoda: Digenea)(Plates 14-1-14.25)—sometimes referred
to as flukes, trematodes, digenes, or digenetic trematodes-comprise the vast majority of …

Introduction Schistosomiasis is a chronic parasitic trematode disease that affects over 240
