“…In parasite-infected individuals, lysozyme and respiratory burst activities were decreased, while in dab with lymphocystis, non-specific cellular responses appeared not to be affected. This is in contrast to observations in American plaice, Hippoglossoides platessoides, where head kidney cells displayed enhanced phagocytosis and respiratory burst activity in association with lymphocystis infection (Marcogliese et al 2001). Other diseases, such as epidermal hyperplasia/papilloma or skin ulcers, were not observed to be associated with altered lysozyme or head kidney phagocyte activity.…”

The marine flatfish dab (Limanda limanda), which lives in direct contact with contaminated sediments, is frequently used as a sentinel species in international monitoring programmes on the biological effects of contaminants. In this study, immune responses were recorded as indicators of sublethal chronic effects of contaminants, in addition to measurement of the induction of mono-oxygenase ethoxyresorufin O-deethylase (EROD) in liver cells, the inhibition of acetylcholin esterase (AChE) in muscle and a quantification of grossly visible diseases and parasites. In total, 336 dab were analysed from five sampling areas in the North Sea, including the German Bight, the Dogger Bank, the Firth of Forth, and two locations close to oil and gas platforms (Ekofisk and Danfield). When considering plasma lysozyme levels, pinocytosis and respiratory burst activity of head kidney leucocytes, a clear gradient could be observed with decreased levels in individuals collected from the Firth of Forth and locations near the oil or gas platforms compared with dab from the Dogger Bank or the German Bight. Individuals with induced EROD activity displayed reduced lysozyme and respiratory burst activities. Lysozyme levels were also reduced in dab with lymphocystis or with nematodes. The data obtained indicate that the assessment of innate immune parameters in a monitoring programme provides supplementary information about immunomodulatory effects associated with the exposure of fish to contaminants. In particular, concentrations of plasma lysozyme, which can be analysed in an easy and inexpensive assay, are considered to be an appropriate parameter for use in a battery of other bioindicators.

“…Lymphocystis disease has been described in more than 125 species of fish from both marine and freshwater environments (Anders 1989;Marcogliese et al 2001;Paperna et al 2001;Bunkley-Williams et al 2002;Sheng et al 2007a;Hossain et al 2008;Xu et al 2014;Huang et al 2015). The affected species belongs to evolutionarily advanced orders of bony fish (teleosts), mainly including the families Cichlidae, Osphronemidae, Centrarchidae, Gobiidae, Chaetodontidae, Pomacentridae, Sciaenidae, Serranidae and Pleuronectidae.…”

“…Recently, Dezfuli et al (2012) demonstrated that piscidin 3-expressing acidophilic granulocytes, but not mast cells, are recruited and activated in the dermis of gilthead sea bream in response to LCDV infection. In addition, an enhanced phagocytic capability was observed in head kidney cells from American plaice [Hippoglossoides platessoides (Fabricius, 1780)] suffering LCD (Marcogliese et al 2001).…”

Lymphocystis disease virus (LCDV) is the causative agent of a well-known fish viral disease that is characterized by hypertrophy of fibroblastic cells in the connective tissue. This viral disease affects more than 125 wild and cultured species of teleost fish from marine and freshwater environments and has a cosmopolitan geographical distribution. In aquaculture systems, the prevalence of LCDV infection is very high, likely reflecting the horizontal transmission of this virus. The incidence rate of the disease may reach 70%, causing significant economic losses for the aquaculture industry. This review provides information on the taxonomy, viral properties, epizootiology and pathogenesis, diagnostic methods and control measures of LCDV infection in fish.
