Latief L, Gilbert BM, Avenant-Oldewage A. Effects of water quality on fish parasite biodiversity and physiological responses in the host fish Clarias gariepinus from a eutrophic lake subjected to acid mine drainage in South Africa. INTEGRATED ENVIRONMENTAL ASSESSMENT AND MANAGEMENT 2023. [PMID: 38131523 DOI: 10.1002/ieam.4885] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 09/08/2023] [Revised: 11/20/2023] [Accepted: 12/13/2023] [Indexed: 12/23/2023]
Abstract
Elevated concentrations of contaminants have negative impacts on aquatic organisms and their parasites. Changes in parasite infections have been proposed as a technique for monitoring the health of aquatic ecosystems. Furthermore, alterations in physiological responses (biomarkers) of organisms have also been used to delineate ecosystem quality. Lake Heritage is situated along the Crocodile River in Muldersdrift, Gauteng, South Africa, and is subject to contamination by acid mine drainage. Clarias gariepinus is a well-studied bioindicator species and host to numerous endoparasites and ectoparasites. The aims of this study were to delineate the health status of Lake Heritage through a multifaceted approach by comparing the water quality, biomarker responses, and parasite biodiversity of C. gariepinus, compared to unexposed laboratory-reared fish. Physical and chemical water quality parameters were determined using a hand-held probe, test kits, and element analysis with inductively coupled plasma-mass spectrometry. Biomarker responses in the gill, liver, and muscle tissues from C. gariepinus were assessed for total protein, metallothioneins, superoxide dismutase (SOD), and reduced glutathione (GSH) concentrations and activities of acetylcholinesterase and catalase. Results for water quality variables showed higher pH, nitrate, hardness, and copper levels compared with the South African Target Water Quality Guidelines. Catalase activity and concentrations of SOD and reduced GSH showed a response in C. gariepinus to the water quality. Ectoparasites had lower prevalence and mean intensity than endoparasites. However, there were no differences in the physiological responses between infected and uninfected hosts. The study shows that the eutrophic conditions in Lake Heritage cause biomarker responses in the host when compared to host fish in laboratory conditions.

A Novel Disease (Water Bubble Disease) of the Giant Freshwater Prawn Macrobrachium rosenbergii Caused by Citrobacter freundii: Antibiotic Treatment and Effects on the Antioxidant Enzyme Activity and Immune Responses. Antioxidants (Basel) 2022; 11:antiox11081491. [PMID: 36009210 PMCID: PMC9405353 DOI: 10.3390/antiox11081491] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/14/2022] [Revised: 07/23/2022] [Accepted: 07/26/2022] [Indexed: 12/10/2022] Open
Abstract
The giant freshwater prawn, Macrobrachium rosenbergii, is an important and economical aquaculture species widely farmed in tropical and subtropical areas of the world. A new disease, “water bubble disease (WBD)”, has emerged and resulted in a large loss of M. rosenbergii cultured in China. A water bubble with a diameter of about 7 mm under the carapace represents the main clinical sign of diseased prawns. In the present study, Citrobacter freundii was isolated and identified from the water bubble. The optimum temperature, pH, and salinity of the C. freundii were 32 °C, 6, and 1%, respectively. A challenging experiment showed that C. freundii caused the same typical signs of WBD in prawns. Median lethal dose of the C. freundii to prawn was 104.94 CFU/g. According to the antibiogram tests of C. freundii, florfenicol and ofloxacin were selected to evaluate their therapeutic effects against C. freundii in prawn. After the challenge with C. freundii, 86.67% and 72.22% survival of protective effects against C. freundii were evaluated in the oral florfenicol pellets and oral ofloxacin pellets feding prawns, respectively, whereas the mortality of prawns without fed antibiotics was 93%. After antibiotic treatment and C. freundii infection, the activities of superoxide dismutase (SOD), catalase (CAT), glutathione peroxidase (GPx), glutathione S-transferase (GST), malondialdehyde (MDA), acid phosphatase (ACP), alkaline phosphatase (ALP), and lysozyme (LZM) in the hemolymph and hepatopancreas of the prawns and the immune-related gene expression levels of Cu/Zn-SOD, CAT, GPx, GST, LZM, ACP, anti-lipopolysaccharide factor, crustin, cyclophilin A, and C-type lectin in hepatopancreas were all significantly changed, indicating that innate immune responses were induced by C. freundii. These results can be beneficial for the prevention and control of C. freundii in prawns.

Abstract
Disease epidemics in shrimp aquaculture increase apace with the development of aquaculture systems throughout the world. The disease caused by Vibrio spp. (vibriosis) is considered the most devastating, which has made it the most feared bacterial disease in the shrimp sector. In aquaculture, several strategies have already been applied to control Vibrio strains, including chemicals, probiotics, antibiotics, natural products from plants, including plant oils; hence, there has been considerable attention for using plants in shrimp aquaculture to provide sustainable, eco-friendly and safe compounds, such as alkaloids, saponins, terpenoids and flavonoids for replacing chemical compounds and antibiotics in current aquaculture. Medicinal plants may also have immunostimulating activity, increase growth and resistance in shrimps. The present paper aims to review the inhibition of Vibrio spp. in shrimp by medicinal plants, using both in vitro or/and in vivo techniques. Several medicinal plants appear capable of inhibiting growth of Vibrio pathogens outside living shrimp or in the body of shrimp, through enhancing growth and immune capacity when shrimps are fed or injected with them. In the current review Gracilaria spp. (Gracilariaceae family) and Sargassum spp. (family Sargassaceae) have been used most for in vitro and in vivo experiments. Among the terrestrial plants, Eucalyptus camaldulensis, Psidium guajava, Rhodomyrtus tomentosa, and Syzygium cumini (Myrtaceae family) had significant activity against Vibrio.

Abstract
Natural and anthropogenic stressors, including parasites and pesticides, may induce oxidative stress in animals. Measuring oxidative stress responses in sentinel species that are particularly responsive to environmental perturbations not only provides insight into host physiology but is also a useful readout of ecosystem health. Newly metamorphosed northern leopard frogs (Lithobates pipiens), a sentinel species, were collected from agricultural and non-agricultural wetlands exposed to varying concentrations of the herbicide atrazine. Significant effects of certain parasites' abundance and their interaction with atrazine exposure on frog oxidative stress were identified. Specifically, increased protein levels were detected in frogs infected with echinostome metacercariae. In addition, the nematode Oswaldocruzia sp. was significantly associated with increased thiol concentration and catalase activity. Significant parasite × atrazine interactions were observed for atrazine exposure and the abundance of Oswaldocruzia sp. on thiol, as thiol concentrations increased with parasite abundance at low atrazine localities and decreased in high atrazine wetlands. In addition, a significant interaction between the abundances of Oswaldocruzia sp. and gorgoderid trematodes on thiol concentrations was observed. These findings demonstrate that studies of oxidative stress on animals in natural ecosystems should account for the confounding effects of parasitism, particularly for amphibians in agricultural landscapes.

Abstract
In this study, we aimed to record, for the first time, parasitic infestation by the isopod Probopyrus pandalicola on the prawn Macrobrachium acanthurus, as well as to register some ecological interactions. We hypothesized that the parasitic infection is able to negatively affect the prawn's nutritional condition and that this interaction can modify growth relationships in male individuals. We collected both parasitized (n = 25) and parasite-free (n = 25) individuals in several locations of the Contas River, state of Bahia, Brazil, which had their morphometric characteristics determined, including of the parasites. Relative growth models were constructed for both groups in order to compare slopes and intercepts and determine if the growth patterns are modified by the parasite. We also determined the body condition of the prawns, which was also compared between the two groups. Our results clearly demonstrated that the parasitic infection is able to induce modifications in relative growth patterns in male individuals and that this isopod is capable of reducing the nutritional condition of the prawns. This study indicates that this parasite can induce deleterious effects in the prawn, but individually. Further studies should be conducted to assess the relevance of our findings in conservation and management.

Pathogens 2020; 9:pathogens9110932.

Abstract
The endemic fan mussel (Pinna nobilis) in the Mediterranean Sea is at high risk of disappearance due to massive mortality events. The aim of the study was to evaluate the antioxidant response of P. nobilis collected in the Balearic Islands (Western Mediterranean) before and after the mass mortality event. Individuals collected before (between 2011 and 2012) and after (between 2016 and 2017) the event were analyzed by histological, molecular, and biochemical methods to compare pathogenic loads and biochemical responses. All the individuals collected during 2016–2017 presented symptoms of the disease and were positive for Haplosporidium pinnae, while acid-fast bacteria or/and Gram-negative bacteria were detected in some individuals of both sampling periods. The activities of the antioxidant enzymes catalase and superoxide dismutase in the gills were significantly lower in P. nobilis affected with the parasite compared to those in the asymptomatic ones, while levels of malondialdehyde, as an indicator of lipid peroxidation, were higher in infected individuals. When analyzing the differential effects of H. pinnae and Mycobacterium sp. on P. nobilis, it was observed that significant effects on biomarkers were only observed in the presence of H. pinnae. Co-infection of P. nobilis by H. pinnae with other pathogens such as Mycobacterium sp. constitutes a serious problem due to its high mortality rate in the Balearic Island waters. This concerning situation for P. nobilis is favored by a reduction in antioxidant defenses related to H. pinnae infection that induces oxidative stress and cell damage.

Abstract
Mangroves are tidal wetlands that are often under strong anthropogenic pressures, despite the numerous ecosystem services they provide. Pollution from urban runoffs is one such threats, yet some mangroves are used as a bioremediation tool for wastewater (WW) treatment. This practice can impact mangrove crabs, which are key engineer species of the ecosystem. Using an experimental area with controlled WW releases, this study aimed to determine from an ecological and ecotoxicological perspective, the effects of WW on the red mangrove crab Neosarmatium africanum. Burrow density and salinity levels (used as a proxy of WW dispersion) were recorded, and a 3-week caging experiment was performed. Hemolymph osmolality, gill Na+/K+-ATPase (NKA) activity and gill redox balance were assessed in anterior and posterior gills of N. africanum. Burrow density decreased according to salinity decreases around the discharged area. Crabs from the impacted area had a lower osmoregulatory capacity despite gill NKA activity remaining undisturbed. The decrease of the superoxide dismutase activity indicates changes in redox metabolism. However, both catalase activity and oxidative damage remained unchanged in both areas but were higher in posterior gills. These results indicate that WW release may induce osmoregulatory and redox imbalances, potentially explaining the decrease in crab density. Based on these results we conclude that WW release should be carefully monitored as crabs are key players involved in the bioremediation process.

Abstract
This study mainly evaluated the effects of orally administered beta 1,3/1,6-glucan and vitamin C on the nonspecific immune responses of white shrimp (Litopenaeus vannamei). In this study, we found that the white shrimp oral administration with 1 g/kg of beta 1,3/1,6-glucan effectively enhanced O2(-) production and phenoloxidase and superoxide dismutase activity. Shrimp were oral administration with 0.2 g/kg of vitamin C presented beneficial nonspecific immune responses and enzyme activity and also observed in the beta 1,3/1,6-glucan treatment groups. Consequently, we compared the alterations in the immune activity between the beta 1,3/1,6-glucan and vitamin C groups and the evidence illustrated that combination of beta 1,3/1,6-glucan and vitamin C presented an additive effect on inducing the nonspecific immune responses of white shrimp.

Abstract
The effect of diet supplemented with Shilajit, a multi-component natural mineral substance on the antioxidant activity, immune response, and disease resistance in freshwater prawn, Macrobrachium rosenbergii (de Man) against Aeromonas hydrophila is reported. The total hemocyte count (THC) and phagocytic activity significantly increased with 2 g kg(-1) supplemented diet on first week and with other enriched diets on weeks 2 and 4. The respiratory burst (RB) activity and glutathione peroxidase (GPx) activity were significantly increased with 2 g kg(-1) supplemented diet on weeks 1 and 2 whereas 2 and 4 g kg(-1) diets on week 4. The phenoloxidase (PO) activity increased significantly with 2 g kg(-1) diet only on second week and with other enriched diets only on fourth week. The superoxide dismutase (SOD) activity increased significantly with any enriched diet during the experimental period except with 6 g kg(-1) diets on first week. However, the glutathione reductase (GR) activity was enhanced significantly only with 2 g kg(-1) enriched diets on weeks 2 and 4. The cumulative mortality of the prawn fed with 2 and 4 g kg(-1) enriched diets was 10% and 15% whereas with 6 g kg(-1) diet the mortality was 20%. The results suggest that diet enriched with Shilajit at 2 g kg(-1) or 4 g kg(-1) positively enhances the antioxidant activity, immunity, and disease resistance in M. rosenbergii against A. hydrophila.

FISH & SHELLFISH IMMUNOLOGY 2016; 54:30-39.

Abstract
The noble scallop Chlamys nobilis belongs to a warm-water mollusk and has been cultured in the sea of southern China since 1980s'. However, accidents of massive mortality have often occurred during the winter, and one of the reasons could be accumulation of harmful reactive oxygen species caused by lower temperature. Carotenoids are well known for their anti-oxidant function. To investigate whether carotenoids do play a role in mollusks' antioxidant defense system under lower temperature stress, an acute lower temperature experiment was conducted by using two types of scallops: the orange with higher carotenoids content and the brown with lower carotenoids content. Their CuZnSOD gene was cloned, mRNA expression levels were determined, and SOD activity and carotenoids content were measured. The complete CuZnSOD cDNA consists of 1078 nucleotides with an open reading frame encoding 154 amino acid residues, which has high identity with that of its sister species Chlamys farreri. The mRNA expression levels in both the mantle and gill from the orange scallops were significantly higher (P < 0.05) than that of the brown ones, but the result was the opposite in the blood. SOD activity in the mantle and gill from the orange scallops was significantly higher than (P < 0.05) that from the brown ones. Further, significantly positive correlations were found among CuZnSOD gene transcript levels, SOD activity and total carotenoids content in the orange scallops. The present results suggested that carotenoids could play roles in antioxidant defense system by upregulating gene expression under lower temperature stress in the noble scallop.

Abstract
Macroalgae are potentially excellent sources of highly bioactive secondary metabolites that are useful for the development of new functional ingredients. This study was conducted to determine whether methanolic extracts from Caulerpa sertularioides and Ulva lactuca macroalgae might be possible alternatives for the prevention of shrimp vibriosis, which is caused by Vibrio parahaemolyticus and Vibrio alginolyticus. Macroalgae extracts prepared with methanol as the solvent were evaluated for antibacterial activity with the microplate method. The extracts' effects on the mortality of juvenile Litopenaeus vannamei were evaluated at doses of 150 and 300 mg L(-1). Two independent assays for V. parahaemolyticus and V. alginolyticus were performed. The methanolic extract of C. sertularioides exhibited activity against V. parahaemolyticus and V. alginolyticus, and it had minimal inhibitory concentrations of <1000 and < 1500 μg mL(-1), respectively. L. vannamei mortality in the presence of both The methanolic extract of C. sertularioides exhibited activity against V. parahaemolyticus and V. alginolyticus, and it had minimal inhibitory concentrations of <1000 and <1500 μg mL(-1), respectively. and V. alginolyticus bacteria significantly decreased after treatment with 300 mg L(-1) C. sertularioides methanolic extract.

Abstract
Enzyme activities and gene expression of a number of innate immune parameters in the serum, mucus and skin of Atlantic salmon (Salmo salar) were investigated after challenge with a pathogenic strain of Aeromonas salmonicida (A. salmonicida). Fish were injected in the dorsal muscle with either 100 μl bacterium solution, about 3.05 × 10(7) CFU/ml A. salmonicida, or 100 μl 0.9% NaCl (as control group) and tissue samples were collected at days 0, 2, 4 and 6 post-injection. Lysozyme (LSZ) and alkaline phosphatase (AKP) activities in serum, mucus and skin, and LSZ and AKP mRNA expression in skin of the challenged fish were higher than those of the control at most of the experimental time, with significant differences at several time points (P < 0.05), indicating the involvement of LSZ and AKP in the innate immunity of Atlantic salmon to A. salmonicida. Superoxide dismutase (SOD), peroxidase (POD) and catalase (CAT) activities in mucus and skin, along with the SOD, POD and CAT mRNA expression in skin significantly decreased at day 4 and 6, indicating the decreased antioxidant capacity of the challenged fish. Glutamate pyruvate transaminase (GPT) and glutamic oxalacetic transaminase (GOT) activities in serum, mucus and skin of the challenged group were all higher than those of the control after the injection, and at several time points significant differences were found between the two groups, suggesting organs of fish were impaired after the pathogen infection. The changes of the GPT and GOT activities could be used as potential biomarkers for the impairment of physiological functions caused by the pathogen infection. Identified biomarkers of the immune responses will contribute to the early-warning system of the disease. So this study will not only provide a theoretical basis for vaccine development, but also provide basic data for the establishment of early warning systems for diseases caused by A. salmonicida in Atlantic salmon rearing.

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 non-parasitized 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.

Abstract
The present study aimed to investigate the hepatotoxicity of zederone isolated from Curcuma elata in mice. Adult male mice were intraperitoneally injected with a single dose of zederone (50-300 mg/kg body weight [BW]). Twenty-four hours after the injection, zederone induced liver enlargement with scattered white foci over the organ. The medium lethal dose (LD50) value at 24 hours of zederone was approximately 223 mg/kg BW. Hepatic centrilobular necrosis with marked increases in plasma alanine transaminase activity and total bilirubin levels was observed. Zederone at a dose of 200 mg/kg BW markedly decreased the activity of superoxide dismutase and the hepatic glutathione content, whereas the activity of catalase was not altered. The compound at this dose also increased the messenger RNA (mRNA) expression of Cyp2b10 and Cyp3a11, which are the main drug-metabolizing enzymes in the liver. The mRNA expression of proinflammatory cytokine tumor necrosis factor α was increased. The nuclear factor-E2-related factor 2 protein, which is the transcription factor regulating the antioxidant gene expression, was decreased. The histopathology of massive hepatic centrilobular necrosis with an increase in the expression of cytochrome P450 (Cyp) suggests that the possible potentiation of zederone-induced hepatotoxicity implicated the induction of Cyps, which leads to the formation of biological reactive metabolites and that cause the oxidative stress and liver cell injuries.

Abstract
BACKGROUND The whitefly Bemisa tabaci is a species complex of more than 31 cryptic species which include some of the most destructive invasive pests of crops worldwide. Among them, Middle East-Asia Minor 1 (MEAM1) and Mediterranean have invaded many countries and displaced the native whitefly species. The successful invasion of the two species is largely due to their wide range of host plants, high resistance to insecticides and remarkable tolerance to environmental stresses. However, the molecular differences between invasive and indigenous whiteflies remain largely unknown. METHODOLOGY/PRINCIPAL FINDINGS Here the global transcriptional difference between the two invasive whitefly species (MEAM1, MED) and one indigenous whitefly species (Asia II 3) were analyzed using the Illumina sequencing. Our analysis indicated that 2,422 genes between MEAM1 and MED; 3,073 genes between MEAM1 and Asia II 3; and 3,644 genes between MED and Asia II 3 were differentially expressed. Gene Ontology enrichment analysis revealed that the differently expressed genes between the invasive and indigenous whiteflies were significantly enriched in the term of 'oxidoreductase activity'. Pathway enrichment analysis showed that carbohydrate, amino acid and glycerolipid metabolisms were more active in MEAM1 and MED than in Asia II 3, which may contribute to their differences in biological characteristics. Our analysis also illustrated that the majority of genes involved in 'drug metabolic pathway' were expressed at a higher level in MEAM1 and MED than in Asia II 3. Taken together, these results revealed that the genes related to basic metabolism and detoxification were expressed at an elevated level in the invasive whiteflies, which might be responsible for their higher resistance to insecticides and environmental stresses. CONCLUSIONS/SIGNIFICANCE The extensive comparison of MEAM1, MED and Asia II 3 gene expression may serve as an invaluable resource for revealing the molecular mechanisms underlying their biological differences and the whitefly invasion.

Abstract
Toxoplasma gondii, Cryptosporidium parvum, and Giardia duodenalis are human waterborne protozoa. These worldwide parasites had been detected in various watercourses as recreational, surface, drinking, river, and seawater. As of today, water protozoa detection was based on large water filtration and on sample concentration. Another tool like aquatic invertebrate parasitism could be used for sanitary and environmental biomonitoring. In fact, organisms like filter feeders could already filtrate and concentrate protozoa directly in their tissues in proportion to ambient concentration. So molluscan shellfish can be used as a bioindicator of protozoa contamination level in a site since they were sedentary. Nevertheless, only a few researches had focused on nonspecific parasitism like protozoa infection on aquatic invertebrates. Objectives of this review are twofold: Firstly, an overview of protozoa in worldwide water was presented. Secondly, current knowledge of protozoa parasitism on aquatic invertebrates was detailed and the lack of data of their biological impact was pointed out.

Abstract
Copper Zinc Superoxide dismutase (CuZnSOD) is the family of most important antioxidant metalloenzymes that protects tissues from damage by reactive oxygen species (ROS). In the present study, the intracellular copper zinc SOD from the Asian seabass Lates calcarifer (Lc-icCuZnSOD) was identified by RNA ligase mediated rapid amplification of cDNA ends (RLM-RACE) technique. The full-length cDNA of Lc-icCuZnSOD consisted of 809 nucleotides with an open-reading frame of 465 bp encoding 154 amino acids and N-Glycosylation site (NVTA) within. The predicted molecular mass of the protein is 15.84 kDa with an estimated pI of 5.52. The deduced amino acid sequence of Lc-icCuZnSOD shared high degree of homology with known CuZnSODs from other species. CuZn binding sites (H47, H49, H64, and H121 for Cu(2+) and H72, H81, and ASP84 for Zn(2+)), two cysteine residues (aa 58 and 147) that form a disulfide bond, and CuZnSOD family signature sequences (GFHVHAFGDNT, aa 45-55 and GNAGGRLACGVI, aa 139-150) were highly conserved among fish species. Temporal and tissue specific expression of Lc-icCuZnSOD was significantly differentially altered in Asian seabass challenged with Vibrio anguillarum indicating possible role in antioxidant activities involved in the innate immune defense mechanisms.

Abstract
Superoxide dismutases (SODs) are important for the survival of insects under environmental and biological stresses; however, little attention has been devoted to the functional characterization of SODs in whitefly. In this study, an intracellular copper/zinc superoxide dismutase of whitefly (Bemisia tabaci) (Bt-CuZnSOD) was cloned. Sequence analysis indicated that the full length cDNA of Bt-CuZnSOD is of 907 bp with a 471 bp open reading frame encoding 157 amino acids. The deduced amino acid sequence shares common consensus patterns with the CuZnSODs of various vertebrate and invertebrate animals. Phylogenetic analysis revealed that Bt-CuZnSOD is grouped together with intracellular CuZnSODs. Bt-CuZnSOD was then over-expressed in E. coli and purified using GST purification system. The enzymatic activity of purified Bt-CuZnSOD was assayed under various temperatures. When whiteflies were exposed to low (4°C) and high (40°C) temperatures, the in vivo activity of Bt-CuZnSOD was significantly increased. Furthermore, we measured the activities of several antioxidant enzymes, including SOD, catalase and peroxidase, in the whitefly after transferring the whitefly from cotton to tobacco (an unfavorable host plant). We found that the activity of SOD increased rapidly on tobacco plant. Taken together, these results suggest that the Bt-CuZnSOD plays a major role in protecting the whitefly against various stress conditions.

Abstract
Cellular oxidative stress responses are caused in many ways, but especially by disease and environmental stress. After the initial burst of reactive oxygen species (ROS), the effective elimination of ROS is crucial for the survival of organisms and is mediated by antioxidant defense mechanisms. In this paper, we investigate the possible antioxidant function of Penaeus monodon Receptor for Activated C Kinase-1 (Pm-RACK1). When Pm-RACK1 was over-expressed in Escherichia coli cells or Spodoptera frugiperda (Sf9) insect cells exposed to H(2)O(2), it significantly protected the cells from oxidative damage induced by H(2)O(2). When recombinant Pm-RACK1 protein was expressed as a histidine fusion protein in E. coli and purified with a Ni(2+)-column it possessed antioxidant functions that protected DNA from metal-catalyzed oxidation. Shrimp (Penaeus vannamei) held at an alkaline pH had a much higher hepatopancreatic expression of Pm-RACK1 than in those held at pH 7.4. The exposure of shrimp to alkaline pH is also known to increase ROS production. These results provide strong evidence that Pm-RACK1 can participate in the shrimp antioxidant response induced by the formation of ROS.

Abstract
Parasites were examined in yellow perch, Perca flavescens (Mitchill, 1814), from four localities ranging in degree of pollution in the St. Lawrence River, Quebec, Canada, to examine the effects of the most prevalent parasite species on expression of biomarkers of oxidative stress. Various biomarkers appeared to be affected by the infection levels of Apophallus brevis Ransom, 1920 and genus Diplostomum von Nordmann, 1832. For certain biomarkers, interactions between infection level and pollution type were detected for A. brevis, Diplostomum spp., and genus Ichthyocotylurus Odening, 1969. Activity of glutathione reductase in gill tissue decreased with increasing numbers of A. brevis, but only at the two most polluted localities. Catalase activity in kidney increased with numbers of Diplostomum spp. at the polluted localities, but not at the two least contaminated sites. Results suggest that parasites may affect expression of biomarkers of pollution and that pathogenicity of parasites may be enhanced under polluted conditions. Exposure to contaminants appears to reduce tolerance, but not resistance, to parasites in yellow perch in this system. This type of immunosuppression may be widespread in polluted ecosystems.

Abstract
White shrimp Litopenaeus vannamei injected with saline, and injected with tryptic soy broth (TSB)-grown Vibrio alginolyticus at 1.0 x 10(5) and 1.8 x 10(5) colony-forming units (cfu) shrimp(-1) were examined for hyaline cell (HC) counts, granular cell (GC) counts, total haemocyte counts (THCs), phenoloxidase (PO) activity, respiratory burst (RB) and superoxide dismutase (SOD) activity after 1-168 h. Shrimp that received no injection served as the control. The shrimps which received V. alginolyticus at both doses showed significant decreases in these parameters after 6-96 h. The values for HC and SOD activity decreased earlier and then RB. The time to cause maximum depletion of haemocytes (haemocytopenia), PO activity, RB, and SOD activity were 12, 72, 48, and 24 h post-injection, respectively. The HC, GC, and RB returned to the original values earlier at 72 h, followed by SOD activity at 96 h, and then PO activity at 168 h post-infection. It was concluded that an injection of V. alginolyticus rapidly reduced the shrimp's immunity by decreasing HC, GC, SOD activity, RB, and PO activity within 3-24 h, followed by a slow recovery during 72-168 h post-injection. Furthermore, white shrimp L. vannamei which received V. alginolyticus showed a 6-9 h later response in PO activity, and a 72-96 h later recovery of PO activity, compared to the responses in RB and SOD activity indicating their roles in shrimp defence and immunity.

[PMID: 17574438 DOI: 10.1016/j.fsi.2007.04.008] [Citation(s) in RCA: 72] [Impact Index Per Article: 4.2] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 02/01/2007] [Revised: 04/18/2007] [Accepted: 04/26/2007] [Indexed: 05/15/2023]
Abstract
Cu, Zn superoxide dismutases (SODs) are metalloenzymes that represent one important line of defence against reactive oxygen species (ROS). A cytoplasmic Cu, Zn SOD cDNA sequence was cloned from scallop Chlamys farreri by the homology-based cloning technique. The full-length cDNA of scallop cytoplasmic Cu, Zn SOD (designated CfSOD) was 1022 bp with a 459 bp open reading frame encoding a polypeptide of 153 amino acids. The predicted amino acid sequence of CfSOD shared high identity with cytoplasmic Cu, Zn SOD in molluscs, insects, mammals and other animals, such as cytoplasmic Cu, Zn SOD in oyster Crassostrea gigas (CAD42722), mosquito Aedes aegypti (ABF18094), and cow Bos taurus (XP_584414). A quantitative reverse transcriptase real-time PCR (qRT-PCR) assay was developed to assess the mRNA expression of CfSOD in different tissues and the temporal expression of CfSOD in scallop challenged with Listonella anguillarum, Micrococcus luteus and Candida lipolytica respectively. Higher-level mRNA expression of CfSOD was detected in the tissues of haemocytes, gill filaments and kidney. The expression of CfSOD dropped in the first 8-16 h and then recovered after challenge with L. anguillarum and M. luteus, but no change was induced by the C. lipolytica challenge. The results indicated that CfSOD was a constitutive and inducible acute-phase protein, and could play an important role in the immune responses against L. anguillarum and M. luteus infection.

Abstract
A cDNA encoding a mitochondrial manganese superoxide dismutase (mtMnSOD) was cloned from the hepatopancreas of giant freshwater prawn Macrobrachium rosenbergii using reverse transcription polymerase chain reaction (RT-PCR) by degenerate primers. Both 3'- and 5'-regions were isolated by rapid amplification of cDNA end (RACE) PCR method. Analysis of nucleotide sequence revealed that the mtMnSOD full-length cDNA consists of 1202bp containing an open reading frame of 654bp, which encodes a protein consisting of 218 amino acids including a signal peptide of 16 amino acid residues. The calculated molecular mass of the mature proteins (202 amino acids) is 24kDa with an estimated pI of 7.12. Two putative N-glycosylation sites, NXT and NXS were observed in the mtMnSOD. Manganese superoxide dismutase signatures from 180 to 187 (DVWEHAYY), and four conserved amino acids responsible for binding manganese were observed (H48, H96, D180 and H184). Sequence comparison showed that the mtMnSOD deduced amino acid sequence of Macrobrachium rosenbergii has similarity of 88%, 78%, 56%, 54% and 46% to that of blue crab Callinectes sapidus, crucifix crab Charybdis feriatus, brown shrimp Farfantepenaeus aztecus, European lobster Palinurus vulgaris, and grass shrimp Palaemontes pugio, respectively, and has similarity of 45%, 44%, 43%, 26% and 25% to cytMnSOD (cytosolic MnSOD) deduced amino acid sequence of blue crab C. sapidus, prawn M. rosenbergii, tiger shrimp Penaeus monodon, grass shrimp P. pugio and brown shrimp F. aztecus, respectively. Quantitative real-time RT-PCR analysis showed that levels of mtMn-SOD transcripts in hepatopancreas and haemocytes were not significantly different between the M. rosenbergii injected with Lactococcus garvieae, and that injected with saline after 3h to 24h.

Abstract
A copper/zinc superoxide dismutase (Cu,Zn-SOD) cDNA was cloned from the hepatopancreas of giant freshwater prawn Macrobrachium rosenbergii using reverse transcription-polymerase chain reaction (RT-PCR) by degenerate primers. Both 3'- and 5'-regions were isolated by the rapid amplification of cDNA ends method. Analysis of nucleotide sequence revealed that the Cu,Zn-SOD cDNA clone consists of 845 bp with an open reading frame of 603 bp encoding a protein of 201 amino acids with a 22 amino acid signal peptide. The calculated molecular mass of the mature proteins (179 amino acids) is 21 kDa with an estimated pI of 4.75. Two putative N-glycosylation sites, NXT and NXS, were observed in the Cu,Zn-SOD. Four conserved amino acids responsible for binding copper (H86, H89, H106 and H163) and four conserved amino acids responsible for binding zinc (H106, H114, H123 and D126) were observed. Sequence comparison showed that the Cu,Zn-SOD deduced amino acid sequence of M. rosenbergii has similarity of 60% and 64% to that of freshwater crayfish Pacifastacus leniusculus ecCu,Zn-SOD and blue crab Callinectes sapidus ecCu,Zn-SOD, respectively. Quantitative real-time RT-PCR analysis showed that Cu,Zn-SOD transcripts in haemocytes of M. rosenbergii increased 3h and 6h after injection of Lactococcus garvieae, whereas Cu,Zn-SOD transcripts decreased in the hepatopancreas 3h after L. garvieae injection.

Abstract
White spot syndrome virus (WSSV) is the causative agent of White Spot disease of shrimp, causing mass mortalities in aquaculture. WSSV infection causes oxidative stress by the release of reactive oxygen species (ROS) that are toxic to the cells. The antioxidant enzymes associated with oxidative stress during the process of pathogenesis of WSSV in the infected tissues (hemolymph, hepatopancreas, gills and muscle) of Fenneropenaeus indicus were quantitatively determined at different time intervals post infection (0, 24, 48, 72 and after 72 h (moribund)). The level of lipid peroxidation, the activities of superoxide dismutase, catalase, glutathione peroxidase, and also the activities of the non-enzymic antioxidants glutathione-S-transferase, reduced glutathione and glutathione reductase in healthy and WSSV-infected hemolymph, hepatopancreas, gills and muscle of F. indicus showed marked differences at different times during the course of infection. The level of lipid peroxidation was higher in WSSV-infected muscle, hemolymph, gills and hepatopancreas than in uninfected F. indicus. Significant reductions in the activities of superoxide dismutase, catalase, glutathione-S-transferase, reduced glutathione, glutathione peroxidase and glutathione reductase were observed in WSSV-infected compared with uninfected animals. The increased lipid peroxidation in WSSV-infected shrimp may be due to increased oxidative stress in the cells as a result of depletion of antioxidant scavenger systems. The reduced activity of antioxidant enzymes in WSSV-infected animals could be due to inactivation of antioxidant enzymes by oxidative stress thereby generating free radicals, which accumulate in the cells. Further understanding of the biochemical alterations induced by viral infections, including changes in the antioxidant status and oxidative stress, could help to advance the therapeutic armamentarium for control of WSSV in shrimp.

Abstract
White shrimp Litopenaeus vannamei held in 25 per thousand seawater were injected with TSB-grown Vibrio alginolyticus (1 x 10(4) cfu shrimp(-1)), and then transferred to 5, 15, 25 (control) and 35 per thousand. Over 24-96 h, the mortality of V. alginolyticus-injected shrimp held in 5 per thousand and 15 per thousand was significantly higher than that of shrimp held in 25 per thousand and 35 per thousand, and the mortality of V. alginolyticus-injected shrimp held in 5 per thousand was the highest. Shrimp held in 25 per thousand and then transferred to 5, 15, 25 (control) and 35 per thousand were examined for THC (total haemocyte count), phenoloxidase activity, respiratory burst, superoxide dismutase (SOD) activity, phagocytic activity and clearance efficiency to V. alginolyticus after 12-72 h. The THC, phenoloxidase activity, respiratory burst, SOD activity, phagocytic activity and clearance efficiency decreased significantly for the shrimp held in 5 and 15 per thousand after 12 h. It is concluded that the shrimp transferred from 25 per thousand to low salinity levels (5 and 15 per thousand) had reduced immune ability and decreased resistance against V. alginolyticus infection.

Abstract
Haemocyte count, phenoloxidase activity, respiratory burst (release of superoxide anion), superoxide dismutase (SOD) activity, glutathione peroxidase (GPX) activity, phagocytic activity and clearance efficiency to the pathogen Vibrio alginolyticus were measured in white shrimp Litopenaeus vannamei juveniles (12.3 +/- 1.2 g) which had been fed diets containing sodium alginate at 0.5, 1.0, 2.0 g kg(-1) after five months. L. vannamei fed a diet containing 2.0 g kg(-1) sodium alginate had increased phenoloxidase activity, respiratory burst and SOD activity, but decreased GPX activity significantly. L. vannamei fed a diet containing 2.0 g kg(-1) sodium alginate had increased phagocytic activity and the shrimp fed a diet containing sodium alginate at 0.5, 1.0 or 2.0 g kg(-1) had increased clearance efficiency to V. alginolyticus. In another experiment, L. vannamei, which had been fed control diet, or sodium alginate-containing diets after 5 months, were challenged with V. alginolyticus at 2 x 10(6) colony-forming units (CFU) shrimp(-1) and then placed in seawater of 15 per thousand. The survival of shrimp fed a diet containing 2.0 g kg(-1) after one day, and the survival of shrimp fed diets containing sodium alginate at 0.5 and 1.0 g kg(-1) after 2-4 days increased significantly, as compared to that of shrimp fed control diet. It is therefore concluded that administration of sodium alginate in the diet at 2.0 g kg(-1) or less could enhance the immune ability of L. vannamei and increase its resistance to V. alginolyticus infection.

Abstract
The immunomodulatory action of superoxide dismutase (SOD) and its possible use as an indicator of immune responses in American white shrimp (Litopenaeus vannamei) were studied. Juvenile shrimp were immersed in aerated beta-glucan and sulfated polysaccharide solutions for 6 h. SOD activity in haemocytes and muscle was quantified to evaluate whether beta-glucan and sulfated polysaccharide induce immunostimulatory activity. Haemocytes and muscle showed similar increased levels of SOD activity (1.5- and 1.4-fold that of control, respectively). Total haemocyte count decreased within the first 24 h after challenge with immunostimulants, but total haemocyte count and total soluble haemocyte protein increased over normal values after 48-120 h. Single immunostimulation with beta-glucan and sulfated polysaccharide is sufficient to generate an increase in the antioxidant activity of L. vannamei SOD.

Abstract
Juvenile American white shrimp (Litopenaeus vannamei) were immersed in aerated beta-glucan and sulphated polysaccharide solutions for 1, 3 and 6 h. Superoxide anion and SOD activity in haemocytes and muscle were investigated to evaluate whether beta-glucan and sulphated polysaccharide induce any immunostimulatory activity. Haemocytes and muscle showed different levels of superoxide anion generation and SOD activity (2.0 and 14 times that of control, respectively) when shrimp were immersed for 6 h in aerated sea water containing beta-glucan and sulphated polysaccharide. Total haemocyte count (THC) decreased within the first 24 h after challenge with immunostimulants, but THC and total soluble haemocyte protein increased over normal values after 48-120 h. Single immunostimulation with beta-glucan and sulphated polysaccharide is capable of generating an increase in the respiratory burst of L. vannamei haemocytes.
