Abstract
Aquaculture is an essential and growing component of agricultural and global ecosystems worldwide. Aquaculture provides more than 25% of the total aquatic food consumption by humans. The development of the aquaculture industry should be followed in successive industrial years, and therefore it is necessary to pay attention to the management and type of farming system that is compatible with the environment. The use of antibiotics for disease control has been criticised for their negative effects, including the emergence of antibiotic-resistant bacteria, the suppression of the immune system and the environment, and the accumulation of residue in aquatic tissues. The use of these products reduces the need for treatments, enhances the effect of vaccines, and, in turn, improves production indicators. Medicinal plants have increasingly been used in recent years as a disease control strategy in aquaculture, boosting the immune system of aquatic animals and helping to develop strong resistance to a wide range of pathogens. Therefore, this review aims to provide an overview of the recent evidence on the beneficial use of medicinal plants to promote growth and strengthen the immune system in farmed aquatic animals.

Anthelmintic effects of peppermint ( Mentha piperita), lemon ( Citrus limon), and tea tree ( Melaleuca alternifolia) essential oils against Monogenean parasite ( Dactylogyrus sp.) on carp ( Cyprinus carpio). Helminthologia 2023; 60:125-133. [PMID: 37745226 PMCID: PMC10516477 DOI: 10.2478/helm-2023-0019] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/02/2023] [Accepted: 05/30/2023] [Indexed: 09/26/2023] Open
Abstract
Dactylogyrus sp. (Monogenea) is one of the most dangerous pathogens causing parasitic infections in carp (Cyprinus carpio) and other freshwater fish. Due to the adverse effects of conventional chemical treatments on the environment and fish, the use of herbal products in aquaculture against various diseases has increased. In the present study, anthelmintic effects of peppermint (Mentha piperita), lemon (Citrus limon), and tea tree (Melaleuca alternifolia) essential oils against Dactylogyrus sp. found on the gills of carp were studied using in vitro and in vivo experiments. In in vitro experiments, 1, 2.5, 5, and 10 μl/ml concentrations of these essential oils were tested on the parasites and cumulative mortalities were observed to reach 100 % after treatment with peppermint, lemon, and tea tree essential oils of 1 μl/ml concentration in approximately 15, 10 and 2 min, respectively. The in vitro experiments demonstrated that the cumulative mortality of the parasites increased with essential oil concentration and exposure duration. As the concentration of essential oil used increased, the observed mean time to death of parasites decreased. In in vivo experiments, median effective concentrations (EC50) as assessed by in vitro tests for peppermint and lemon essential oils in 5 min exposure and EC50 concentration for tea tree essential oil in 2 min exposure was applied on fish as a single bath and there was a significant decrease in the mean parasite intensities (p<0.05). Antiparasitic efficacies of peppermint, lemon, and tea tree essential oils were determined as 28.23 %, 30.95 %, and 35.31 %, respectively. The tea tree oil was the most effective and peppermint oil was the least effective in both in vitro and in vivo experiments. All three herbal essential oils tested in this study have weak antiparasitic potential against monogenean infections in fish.

Abstract
Purpose Diplectanum is a life-threatening metazoan infecting the gills of Sea bass Dicentrarchus labrax causing a wide-ranging extensive economic loss in the aquaculture sector. This study has focused on verifying the most effective non-toxic dose of the Neem (Azadirachta indica) and (flubendazole) bath treatment on infested D. labrax fingerlings. Methods In the first phase of the experiment, a total of 180 apparently healthy fingerlings were subdivided into six groups for each treatment. The tested concentrations were 0, 50, 100, 150, 200, and 250 mg L−1 for A. indica and 0, 10, 20, 30, 40, and 50 mg L−1 for flubendazole. The second phase was conducted for one week in five groups for each treatment. The first group was untreated healthy. The remaining groups were infested and received different concentrations of 0, 50, 100, and 150 mg L−1 & 0, 10, 20, and 30 mg L−1 for A. indica and flubendazole, respectively. Results The most toxic dose exhibited high mortality rates at 200 & 250 and 40 & 50 mg L−1 for A. indica and flubendazole, respectively. In the second phase of the experiment, the most effective dose was 150 and 30 mg L−1; for A. indica and flubendazole, respectively. They demonstrated the lowest mortality rates 20.00 & 20.00 %, prevalence rates 43.33 & 23.33%, and mean parasitic intensities were 2.35 & 2.00 accompanied by the highest therapeutic efficacy value 67.85 & 74.6% for both treatments; respectively. Conclusion The most effective anthelmintic efficacy has been assigned for flubendazole and A. indica at 30 and 150 mg L−1.

The effects of dietary compound plant extracts on growth performance, liver and intestine health, and immune related genes expression in hybrid grouper (Epinephelus lanceolatus♂ × Epinephelus fuscoguttatus♀). FISH & SHELLFISH IMMUNOLOGY 2021; 119:11-18. [PMID: 34530079 DOI: 10.1016/j.fsi.2021.09.013] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 07/30/2021] [Revised: 09/09/2021] [Accepted: 09/12/2021] [Indexed: 06/13/2023]
Abstract
The study explored on the effect of dietary compound plant extract supplementation on the growth performance, serum biochemical indicators, liver and intestinal morphological and gene expression levels in the head kidney and spleen of the hybrid grouper (Epinephelus lanceolatus♂× Epinephelus fuscoguttatus♀). The compound plant extracts (BDG) was a mixture of Bupleurum edulis extract, dandelion extract and Ginkgo biloba extract in a ratio of 1:4:1. Basal diets supplemented with BDG at 0, 0.75, 1.5, 3 and 6 g/kg were fed hybrid grouper for 8 weeks. The results showed that dietary 0.75 and 1.5 g/kg BDG supplementation could significantly increase the WGR and SGR of hybrid grouper (P < 0.05). And dietary 0.75 g/kg BDG could also significantly decrease serum aspartate aminotransferase, glucose and lactate dehydrogenase in hybrid grouper (P < 0.05). Dietary BGD supplementation protected the integrity of liver and intestinal morphological structure, reduced the accumulation of liver fat. Dietary BDG supplementation might enhance the immunity of hybrid grouper by regulating the expression of antioxidant and inflammation-related genes in head kidney and spleen of hybrid grouper. Our study demonstrated that the growth promoting effect of Bupleurum extract, dandelion extract and Ginkgo biloba extract in the ratio of 1:4:1 as a compound feed additive was better than any of them as a feed additive alone, and the dosage was less. The optimal additive dosage of BDG was 0.75 g/kg in hybrid grouper diets.

Abstract
Marine aquaculture development is recently impeded by parasitic leech Zeylanicobdellaarugamensis (Hirudinea, Piscicolidae) in Sabah, Malaysia. The parasitic leech infests a variety of cultured fishes in aquaculture facilities. In this study, we evaluated the antiparasitic activity of the chromatographic fractions of the medicinal plant Nephrolepis biserrata methanol extract against Z.arugamensis and highlighted the potential metabolites responsible for the antiparasitic properties through liquid chromatography (LC)–quadrupole time-of-flight (QTOF)–mass spectrometry (MS) analysis. Out of seven fractions obtained through flash column chromatography techniques, three fractions demonstrated antiparasitic properties. Significant parasitic mortality was indicated by fraction 3 at a concentration of 2.50 mg/mL, all the leeches were killed in a time limit of 1.92 ± 0.59 min. followed by fraction 4 (14 mg/mL) in 34.57 ± 3.39 and fraction 5 (15.3 mg/mL) in 36.82 ± 4.53 min. LC-QTOF-MS analysis indicated the presence of secondary metabolites including phytosphingosine (6), pyrethrosin (1), haplophytine (9), ivalin (2), warburganal (3), isodomedin (4) and pheophorbide a (16), representing sphingoid, alkaloid, terpenoid, phenolic and flavonoid groups. Thus, our study indicated that the chromatographic fractions of N. biserrata demonstrated significant antiparasitic activity against the marine parasitic leeches due to the presence of potent antiparasitic bioactive compounds.

Abstract
PURPOSE The aim of this study was to evaluate the in vitro and in vivo efficacy of propolis against Ligictaluridus floridanus on Ictalurus punctatus gills. METHODS This study used an ethanol extract of propolis at a concentration of 300 mg mL-1, with a total polyphenol concentration of 2.77 mg mL-1 as determined by chromatography. In vitro trial used propolis concentrations at 5, 30 as well as 60 mg L-1 and a 70% ethanol control group to treat naturally infected catfish. The in vivo experiment was 16 weeks in duration, consisting of seventy-two fish infected by cohabitation and subjected to one-hour baths every 72 h during the trial. RESULTS In vitro studies showed that parasites exposed to 60 mg L-1 of propolis displayed a significant reduction (p < 0.05) in their survival time. In vivo studies confirmed the reduction of intensity and abundance of Ligictaluridus floridanus on the gills of channel catfish. CONCLUSION This study has provided the first challenge of propolis against L. floridanus on I. punctatus gills and shows that propolis has an anthelmintic effect.

Abstract
The present study is aiming at evaluating the hepatoprotective of Radix Bupleuri extracts (RBE) on the d-galactosamine/lipopolysaccharide (D-GalN/LPS) induced liver injury of hybrid grouper in vitro and in vivo. In vitro, RBE (0, 200, 400 and 800 μg/ml) was added to the hybrid grouper primary hepatocytes before (pretreatment) the incubation of the hepatocytes with D-GalN (20 mM) plus LPS (1 μg/ml) in the culture medium. RBE at concentrations of 200, 400 and 800 μg/ml significantly improved cell viability and inhibited the elevation of TNF-α, IL-1β and IL-6 and significantly down-regulated the caspase-3, caspase-9 and P53 mRNA levels. In vivo administration of RBE at the doses of 0, 200, 400, 800 and 1600 mg/kg in the diet for 8 weeks prior to D-GalN (500 mg/kg) and LPS (20 μg/kg) intoxication. The study indicated that the RBE not only ameliorated liver injury, as evidenced by well-preserved liver architecture, but also significantly increased hepatic antioxidant enzymes activities in the D-GalN/LPS-induced liver injury animal model. Further demonstrating the protective effects of the RBE, we found that pretreatment with the RBE up-regulated the expression of antioxidant genes (GPx and MnSOD), while down-regulated apoptosis-related genes (caspase-3, caspase-9 and P53), immune related genes (MHC2 and TLR3) and pro-inflammatory cytokines (TOR and IKKα) mRNA expression in the liver of hybrid grouper. In brief, the present study showed that RBE can protect hepatocyte injury induced by D-GalN/LPS through elevating antioxidant enzyme activity and suppressing apoptosis and immune inflammatory responses. The results support the use of RBE as a hepatoprotective in fish.

Intensification of livestock rearing often promotes an increase in inappropriate practices that disregard care for the environment, animal health, and workers' health. Intensive fish farming systems are often associated with higher stocking density and massive use of artificial feed. Currently, outbreaks of parasitic, bacterial, and fungal diseases act as major limiting factors for fish farming, meaning that producers have to make use of massive amounts of antibiotics, disinfectants, and pesticides in order to control mortality and avoid huge economic losses. Because of adverse effects on the aquatic environment, terrestrial organisms, and human health (both fish handlers and consumers), this therapy has been criticized. Use of herbal medicines within animal production has shown promise, in that it is natural and biodegradable and has antimicrobial activity against various pathogens, including those relating to fish. Recently, researchers have reported promising effects from many herbal medicines for treating parasitic diseases caused by protozoa and metazoa, and broad activity against bacteria and fungi. This review addresses the current issues regarding indiscriminate use of chemicals and antibiotics in aquaculture and discusses the main findings and methodologies of the latest research on herbal medicines to stimulate and accelerate research in this field, especially in developing countries.

Sarkhail P. Traditional uses, phytochemistry and pharmacological properties of the genus Peucedanum: a review. JOURNAL OF ETHNOPHARMACOLOGY 2014; 156:235-70. [PMID: 25193684 DOI: 10.1016/j.jep.2014.08.034] [Citation(s) in RCA: 76] [Impact Index Per Article: 7.6] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 04/23/2014] [Revised: 08/25/2014] [Accepted: 08/25/2014] [Indexed: 05/22/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE The genus Peucedanum (Apiaceae) comprising more than 120 species is widely distributed in Europe, Asia and Africa. The ethnopharmacologial history of this genus indicated that some extracts of aerial and underground parts of several Peucedanum species have been used in folk medicine for treatment of various conditions, such as cough, cramps, pain, rheumatism, asthma and angina. This review focuses on ethnopharmacological uses of Peucedanum species, as well as the phytochemical, pharmacological and toxicological studies on this genus. Through this review, I intend to highlight the known and potential effects of the Peucedanum species or their isolated compounds and show which traditional medicine uses have been supported by pharmacological investigations. METHODS Information on the Peucedanum species was collected from scientific journals, books, thesis and reports via a library and electronic search (using Google Scholar, Pubmed, Scopus, Web of Science and ScienceDirect). This review covers the available literature from 1970 to the end of September 2013. RESULTS Although, there are about 120 species in this genus, so far many species have received no or little attention and most of pharmacological studies were performed on just about 20 species. Many phytochemical investigations on this genus confirmed that Peucedanum species are rich in essential oils and coumarins. The present review article shows that Peucedanum species have a wide spectrum of pharmacological activities and the most reported activities of Peucedanum plants come back to the presence of coumarins, flavonoids, phenolics and essential oils. CONCLUSIONS The present review confirms that some Peucedanum species have emerged as a good source of the traditional medicine for treatment of inflammation, microbial infections, cardiopulmonary diseases and provides new insights for further investigations on isolated compounds, especially on praeruptorins, to find novel therapeutics and aid drug discovery. However, for using Peucedanum species to prevent and treat various diseases, additional pharmacological studies to find the mechanism of action, safety and efficacy of them before starting clinical trials are required.

Abstract
Disease caused by the parasitic helminths Dactylogyrus spp. results in significant economic damage to the aquaculture industry. Treatment using common chemicals (e.g. formalin) is usually dissatisfactory due to environmental problems, risk of residues, toxicity to fish, and the possibility of anthelmintic resistance. The search for an alternative drug is thus becoming more urgent. This study was designed to evaluate in vivo the anthelmintic efficacy of total saponin (TS), saikosaponin a (SSa), and saikosaponin d (SSd) from radix bupleuri (i.e. the dried root of Bupleurum sp.) based on our previous screening works, with the aim of determining which has commercial potential. Results showed that median effective concentration (EC₅₀) values for TS, SSa, and SSd were 2.01, 1.46, and 0.74 mg l⁻¹, respectively. The acute toxicities against goldfish Carassius auratus for TS, SSa, and SSd were also determined, with median lethal concentration (LC₅₀) of 8.99, 11.20, and 1.54 mg l-1, respectively. The resulting therapeutic indices (TIs) indicated that SSa (TI = 7.67) is a potential therapeutic agent for treating Dactylogyrus infection.

Abstract
Abstract Methanol extracts of 24 traditional medicinal plants with potential anthelmintic activity against Dactylogyrus intermedius (Monogenea) in Goldfish Carassius auratus were investigated. Abrus cantoniensis, Citrus medica, Dioscorea collettii, and Polygonum multiflorum exhibited 100% activity and were selected for further evaluation by applying five solvents (petroleum ether, chloroform, ethyl acetate, methanol, and water) for the extraction of the samples, followed by an in vivo bioassay. Among the plants tested, water, methanol, and ethyl-acetate extracts of P. multiflorum showed the highest efficacies; EC50 values (median concentration that results in 50% of its maximal effect) were 1.9, 5.4, and 9.1 mg/L, respectively, and extracts showed 100% efficacy against Dactylogyrus intermedius at 100, 12.5, and 25 mg/L. This was followed by ethyl-acetate, chloroform, and methanol extracts of Dioscorea collettii, which demonstrated 100% efficacy at 80, 80, and 120 mg/L and had EC50 values of 19.7, 27.1, and 37.8 mg/L, respectively, after 48 h of exposure. Chloroform and ethyl-acetate extracts of C. medica, which exhibited 100% efficacy against Dactylogyrus intermedius at 100 and 125 mg/L, revealed similar activity and had EC50 values of 58.7 and 51.3 mg/L, respectively. The ethyl-acetate and methanol extracts of A. cantoniensis exhibited the lowest activity and had EC50 values of 279.4 and 64.3 mg/L. Acute toxicities of these active extracts were investigated on Goldfish for 48 h. The findings indicated that extracts of the four plants can be developed as a preferred natural antiparasitic for the control of D. intermedius. Received June 15, 2013; accepted February 11, 2014.

Abstract
Intestinal helmintic infection, continue to be a cause of major concern in several parts of the world, particularly in the developing nations. The use of plant extracts to control poultry helminths is increasing in different rearing systems. The anthelmintic activity of ginger and curcumin was studied on the nematode Ascaridia galli. In vitro and in vivo studies were allocated. Live parasites for in vitro studies were collected from the intestine of naturally infected chickens. Some living worms were incubated at 37 °C in media containing ginger at three concentration levels (25, 50, and 100 mg/ml), and others were incubated in media containing curcumin at the same concentration levels. Another living worm group was incubated in media containing albendazole at a dose of 7.5 mg/ml. The extracts' efficacy was exhibited in a concentration-time-dependent manner mainly at 100 mg/ml and after 48 h. The in vivo study takes place on experimentally infected chickens. Group of infected chickens was treated with ginger extract at dose of 100 mg, another group was treated with curcumin extract at dose of 100 mg, and a third group was treated with albendazole at dose of 7.5 mg. In vivo study of ginger and curcumin recorded lower mortality rates than the in vitro study. It is concluded that ginger and curcumin extracts have potential anthelmintic properties against A. galli. Ginger in all concentrations used exhibited a higher death rate observed than curcumin. Their wormicidal effect is concentration-time dependent.

Abstract
Dactylogyrus spp. and Gyrodactylus spp. are helminth ectoparasites that are a significant threat to the aquaculture industry. Existing treatments could cause the threats of anthelmintic resistance, risk of residues, environmental contamination, and toxicity to fish. Importantly, there is no report on a treatment against these two parasites. This study explored the possibility of using the extracts of Santalum album to treat Dactylogyrus sp. and Gyrodactylus sp. infections in goldfish. Results showed that among the four extracts (chloroform, methanol, ethyl acetate, and water) of S. album, the chloroform extract is the most effective and 40 mg/L is a safe and the lowest effective dosage. In addition, we found that Gyrodactylus elegans is more sensitive than Dactylogyrus intermedius when exposed to the extract of the medicinal plant. Finally, it is substantiated that bath treatment with long duration and multiple administrations could eliminate a greater proportion of monogenean infections. These findings show the potential for the development of effective and safe therapy to treat Dactylogyrus sp. and Gyrodactylus sp. infections of fishes.

Abstract
Ichthyophthirius multifiliis (also called "ich") is an external protozoan parasite that may infest almost all freshwater fish species and caused significant economic damage to the aquaculture industry. Since the use of malachite green was banned, there have been relatively few effective alternative strategies for controlling I. multifiliis infections. The present study was designed to screen potential antiparasitic medicinal plants based on our previous studies, and comprehensively evaluate in vitro and in vivo anti-ich activity of selected plant extracts. The screening results showed that the methanol extract of Psoralea corylifolia had the highest activity against I. multifiliis theronts. In vivo theront trials demonstrated that 1.25 mg/L or more concentrations of P. corylifolia methanol extract caused 100 % mortality during the 4-h exposure period, and the subsequent in vitro trials indicated that the minimum concentration of P. corylifolia methanol extract that prevented the initial infestation was 2.50 mg/L. Protomonts and encysted tomonts surviving trials suggested that encysted tomonts were less susceptible to P. corylifolia methanol extract than protomonts, and the methanol extract of P. corylifolia at a concentration of 5.00 mg/L could kill 100 % of protomonts and 88.89 % of encysted tomonts. It was also observed that after 12-h exposure of protomonts or encysted tomonts to 2.50 mg/L of P. corylifolia methanol extract, the theronts emerged from encysted tomonts led to more infection level than the ones in the other groups. The results suggested that whether the protomonts finish encystment is crucial to the survival, reproduction, and theronts infectivity. In addition, our results showed that long duration (24 h) and high concentration (5.00 mg/L) significantly reduced the survival and reproduction of I. multifiliis tomont exited from the fish after in-bath treatment, and it is indicated that P. corylifolia methanol extract had a potential detrimental effect on I. multifiliis trophont in situ.

Abstract
Ichthyophthiriasis is a widespread disease in aquaculture and causes mass mortalities of fish. The development of new antiprotozoal agents for the treatment of Ichthyophthirius multifiliis infections is of increasing interest. The aim of the present study was to investigate the efficacy of 30 medicinal plants against I. multifiliis. The results showed that the methanol extracts of Magnolia officinalis and Sophora alopecuroides displayed the highest antiprotozoal activity against theronts, with 4-h LC(50) values estimated to be 2.45 and 3.43 mg L(-1), respectively. Concentrations of 2.5, 5.0, 10.0, and 20.0 mg L(-1) of M. officinalis extracts resulted in tomont mortality of 9.7, 43.7, 91.3, and 100% at 20 h, respectively. From 40 to 320 mg L(-1) of S. alopecuroides extracts, tomont mortality increased from 29.7 to 100%. Antiprotozoal efficacy against settled tomonts (2 and 10 h) was also applied; the results indicated that encysted I. multifiliis tomonts were less susceptible to these plant extract treatments. In vivo experiments demonstrated that high concentrations of M. officinalis and S. alopecuroides extracts could kill tomonts, and M. officinalis significantly reduced its reproduction (P < 0.05). These results suggested that the methanol extracts of M. officinalis and S. alopecuroides have the potential to be used as an eco-friendly approach for the control of I. multifiliis.

Abstract
In the present study, methanol extracts of 42 traditional medicinal plants with potent anthelmintic activity against Dactylogyrus intermedius (Monogenea) in goldfish (Carassius auratus) were investigated. Cinnamomum cassia, Lindera aggregata, and Pseudolarix kaempferi exhibited 100% activity and were selected for further evaluation by applying five solvents (petroleum ether, chloroform, ethyl acetate, methanol, and water) for the extraction of the samples, followed by the in vivo bioassay. Among the extracts tested, water and methanol extracts of C. cassia showed the highest efficacies with EC(50) values of 13.2 and 12.3 mg L(-1), showing 100% efficacy against D. intermedius at 30.0 and 40.0 mg L(-1), followed by methanol extract of L. aggregata which demonstrated 100% efficacy at 60.0 mg L(-1) with EC(50) value of 17.1 mg L(-1) after 48 h of exposure. Methanol and ethyl acetate extract of P. kaempferi, which exhibited a 100% efficacy against D. intermedius at 60.0 and 50.0 mg L(-1), revealed similar activity with EC(50) values of 23.5 and 23.3 mg L(-1), respectively. Acute toxicity of these active extracts was investigated on goldfish for 48 h and the corresponding median lethal concentrations (LC(50)) of 56.9, 31.3, 88.7, 168.2, and 165.7 mg L(-1), respectively. These findings indicated that these extracts of the three plants can be developed as preferred natural antiparasitic agents for the treatment of D. intermedius.

Abstract
Dregea volubilis (family Asclepediaceae) is widely used as anthelmintic in traditional system of medicine in eastern and southern part of India. The aim of this study was to evaluate the anthelmintic activity of the methanol extract of D. volubilis leaves (MEDV) and to observe its effect through SEM study. Live parasites (trematode Paramphistomum explanatum) were collected from buffalo in 0.9% phosphate-buffered saline (PBS). It was incubated at 37 ± 1°C in media containing either no extract (control), the test drug, MEDV at four dose levels (10, 25, 50, and 100 mg/ml) or the standard drug, albendazole, at a dose of 10 mg/ml. The effectiveness of the extract was judged on the basis of the loss of spontaneous movement and/or complete destruction or death of the trematodes. After being removed from the experimental medium, trematodes were dipped in PBS at 37 ± 1°C and on gentle stimulation, the paralyzed parasite showed immobility. Death was confirmed when it completely lost its motility even when vigorously shaken or dipped in warm water (50°C). The trematodes, both drug treated and others, were further processed for SEM study using standard method. The anthelmintic activity was found with all the doses through paralysis and death of the organisms (p < 0.001). Maximum anthelmintic activity was found with a dose of 100 mg/ml. Minor damage was observed with both suckers, but severe distortion was found with tegumental surface of the treated trematodes. The present SEM-based study established the anthelmintic activity of MEDV.

Abstract
In the present study, scanning electron microscopy is used to demonstrate the surface features of Pseudodactylogyrus anguillae Yin and Sproston (1948) Gussev, 1965 and Pseudodactylogyrus bini Kikuchi (1929) Gussev, 1965 from the European eel Anguilla anguilla. Specimens of the eel A. anguilla were collected from the River Nile, near Mansoura, Dakahlia Province, Egypt. Morphologically, P. anguillae could be distinguished from P. bini based on the total length, the shape and size of the haptor, and the constriction between the haptor and body proper. The general body tegument and the haptoral tegument of both species are microvillous. Possible functions of the microvilli associated with the tegument covering the anterior adhesive areas are discussed. The region of the body proper just anterior to the haptor of P. anguillae, appears to be highly folded and provided with many projections forming scale-like structures. Many surface ciliary sensilla presumed to be sensory structures are found on the tegument of the anterior adhesive area of P. anguillae. Secretory bodies and mucus-like substances are recorded on the tegument covering the anterior adhesive areas of P. anguillae and the haptor of P. bini. The possible role of these secretions in the attachment of the anterior adhesive areas and the posterior attachment haptor to the host tissues are also discussed.
