Oxidative stress in the gill tissues of goldfishes (Carassius auratus) parasitized by Dactylogyrus spp

Abstract

The aim of this study was to investigate the status of oxidative stress in the gill tissues of goldfishes (Carassius auratus) parasitized by Dactylogyrus spp. We therefore compared the concentrations of malondialdehyde (MDA) and total thiol groups in the gill tissues of parasitized and non-parasitized goldfishes. 15 goldfishes parasitized by Dactylogyrus spp. along with 15 nonparasitized goldfishes were selected for the study. A significant increase in MDA concentration (P \ 0.01) and a significant decrease in total thiol groups in the parasitized group, were observed when compared to the non-parasitized group. This is the first study which evaluates the effect of Dactylogyrus spp. on the oxidative stress status of goldfish. The results of the present study revealed that parasitized goldfishes showed more severe oxidative stress and lipid peroxidation than non-parasitized fishes and enhanced lipid peroxidation may be linked to gill damage in goldfishes parasitized by Dactylogyrus spp.

Effects of butyrate glycerides supplementation in high soybean meal diet on growth performance, intestinal morphology and antioxidative status of juvenile black sea bream, Acanthopagrus schlegelii

“…SOD and GSH‐Px are considered as antioxidants, which counteract oxidative stress caused by the ROS in fish (Jiang et al, ; Martínez‐Álvarez, Morales, & Sanz, ). MDA is used as a biomarker of oxidative damage since it is a product of lipid peroxidation (Mozhdeganloo & Heidarpour, ). Our results indicated that supplementation of BG in diet could enhance fish's antioxidant activity and alleviate oxidative damage caused by the ANF in high SBM‐based diets.…”

Biochemical response of two fish species of Gobiidae (Gobiiformes) to Cryptocotyle (Opisthorchiida, Heterophyidae) metacercariae infection from the mouth of the river Chernaya (Black Sea)

“…The host response is characterized by enhanced synthesis of reactive oxygen species aimed at parasite elimination. This process can both inhibit and stimulate antioxidant enzyme activities (Bello et al, 2000;Mukjrakov & Silkina, 2006;Skuratovskaya et al, 2013Skuratovskaya et al, , 2015Skuratovskaya et al, , 2019Mozhdeganloo & Heidarpour, 2014).…”

“…Host responses to parasites are varied and manifest at different levels, including immunological reactions, physiological and biochemical changes in their metabolism. Infections cause biochemical rearrangements in the infected host tissues and can bring about serious structural and functional changes in the infected organs (Mukjrakov & Silkina, 2006;Skuratovskaya et al, 2013Skuratovskaya et al, , 2015Skuratovskaya et al, , 2019Eissa et al 2014;Mozhdeganloo & Heidarpour, 2014;Jang et al, 2017).…”

Dietary Phytogenics and Galactomannan Oligosaccharides in Low Fish Meal and Fish Oil-Based Diets for European Sea Bass (Dicentrarchus labrax) Juveniles: Effects on Gill Structure and Health and Implications on Oxidative Stress Status

“…Under some oxidative/nitrosative stress conditions, such as those attributed to intensive fish culture practices, dietary supplementation with exogenous antioxidants such as vitamins, flavonoids, carotenoids, plant polyphenols, allyl sulfides, curcumin, melatonin, or polyamines may offer a good functional strategy to maintain proper levels of RONS (23,25,26). Although most of the studies investigating fish oxidative stress are related to the effects of xenobiotics or pollutants, the use of functional additives, which are capable of triggering the fish antioxidant system, has gained attention during the last decade in aquaculture because of its potential benefit in preventing diseases and promoting health (17,(27)(28)(29)(30)(31)(32).…”
