The vertebrate immune system is comprised of numerous distinct and interdependent
components. Every component has its own inherent protective value, and the final …

In recent years, the deterioration of the aquaculture ecological environment has led to a high
incidence of fish diseases. Lysozymes, important antimicrobial enzymes, play an important …

The changes in the activities of mucus hydrolytic enzymes and plasma cortisol levels were
examined following infection of Atlantic salmon Salmo salar with the salmon louse …

Parasite factors associated with recognition and selection of the host and the mechanisms in
the host responsible for acceptance or rejection of the invading organism were evaluated …

The directly transmitted viviparous gyrodactylids have high species richness but low
morphological and biological diversity, and many species are recorded from only a single …

Parasitic infections in teleost fish are limited by constitutive innate defence mechanisms that
render the host refractory or reduce the severity of infection. Controlled challenge trials using …

Monogeneans (flatworms) are among the most host-specific of parasites in general and may
be the most host-specific of all fish parasites. Specificity, in terms of a restricted spatial …

Abstract Knowledge concerning the health and welfare of fish is important to conserve
species diversity. Fish mucosal surfaces, and particularly the skin, are of utmost importance …

By means of semi-quantitative RT-PCR, expression of a number of immune relevant genes
was studied in skin of small rainbow trout Oncorhynchus mykiss (Walbaum, 1792) fry during …

Host responses against skin inhabiting monogeneans are commonly observed but the
responsible immune mechanisms in the fish skin are insufficiently described. Based on …
