Abstract
Globally, traditional knowledge systems are a powerhouse of information which can revolutionise the world, if decoded accurately and logically. Plant-based ethno-traditional and folklore curatives/medicines has a firm basis in the psyche of the common masses of West Bengal and Holarrhena pubescens is a representative example of it. This article communication on depicting the anthelmintic efficacy of ethanolic extract and Ethyl acetate fraction of the stem bark of Holarrhena pubescens against the cestode Raillietina spp. through efficacy studies, ultra-structural observations, histochemical and biochemical analysis on some tegumental enzymes i.e., Acid Phosphatase (AcPase), Alkaline Phosphatase (AlkPase), Adenosine Triphosphatase (ATPase) and 5'-Nucleotidase (5'-Nu) along with Gray Level Co-occurrence Matrix (GLCM) analysis of histochemical study. Praziquantel was used as the reference drug. Investigations revealed 10mg/ml dosage of crude extract was the most efficacious dose and amongst the fractions the ethyl acetate fraction showed the most anthelmintic property. Ultrastructural studies through Scanning Electron Microscope (SEM) and Transmission Electron Microscope (TEM) clearly depicted the damage in head, sucker, proglottids, proximal and distal cytoplasm (DC), microtriches (MT), basal lamina (BL), nuclear membrane (NM), and, nucleolus (NL) in the treated worms. Histochemical studies revealed decrease in staining intensity for all the tegumental enzymes in the treated worms compared to control. The GLCM analysis strongly supported the result of histochemical studies. Biochemical studies revealed marked reduction in enzyme activity in the treated worms with maximum reduction in the activity of 5'- Nu (77.8%) followed by ATPase (63.17%).

Abstract
Persicaria hydropiper is a medicinal plant used for the treatment of helminth infections among the Naga people of India. To verify the traditional claim of the plant, an in vitro anthelmintic efficacy of the methanol extract of P. hydropiper leaves was investigated based on the paralytic and mortality effects on Raillietina echinobothrida, an intestinal cestode parasite of domestic fowl, following exposure to 10, 20 and 30 mg/ml concentrations of extract. The effects of extract were also studied on the body surface of the parasites by scanning electron microscopy (SEM). The in vitro results showed an efficacy that was dose-dependent. At the highest dose (30 mg/ml), mortality of parasites occurred in 4.79 ± 0.17 h, in comparison to control, where the parasites survived till 45.63 ± 0.18 h. The SEM observations of extract-treated parasites revealed notable impairment in scolex, with distorted suckers and eroded spines. Also, the tegument was observed to be shrunken with impaired microtriches. The results indicate that P. hydropiper leaves possess noteworthy anthelmintic efficacy and justify their use in traditional medicine against intestinal worms.

Abstract
Biochanin A (BCA) is a multifunctional natural compound that possesses anti-infective, anti-inflammatory, anti-oxidative and hepatoprotective effects. The aim of the study was to assess the therapeutic efficacy of BCA on Schistosoma mansoni-infected mice. Fifty mice were divided into six different groups as non-infected, non-infected BCA-treated, infected untreated, early infected BCA-treated (seven days post-infection (dpi)), late infected BCA-treated 60 dpi and infected praziquantel (PZQ)-treated groups. Parasitological, histopathological examination and immunohistochemical staining of transforming growth factor (TGF)-β, inducible nitric oxide synthase (iNOS) and cyclooxygenase (COX-2) were investigated in liver sections. Cytochrome P450 (CYP450) gene expression of S. mansoni was evaluated by quantitative real-time polymerase chain reaction (RT-qPCR). A single dose of BCA significantly reduced worm burden in early (82.14%) and late infection (77.74%), mean tissue egg load in early (7.27 ± 0.495) and late BCA administration (7.63 ± 0.435) and decreased granuloma size. CYP450 mRNA expression was significantly reduced in early BCA treatment as compared to late treatment which emphasizes that early administration of BCA had more pronounced effects on worms than late administration. Both early and late BCA administration led to significant reduction in inflammatory cytokines as TGF and iNOS. Although the reduction of TGF and iNOS in BCA-treated mice was superior to PZQ, no statistically significant differences were noted. However, a significant downregulation of COX2 was noted in hepatocytes as compared to both infected control and PZQ-treated mice. BCA has schistosomicidal, anti-inflammatory, antioxidant and anti-fibrotic effects and could be regarded as a potential drug in schistosomiasis treatment.

Abstract
The present study aims to find efficient alternatives to synthetic anthelmintics among ethno-veterinary herbs. Ascaridia galli eggs isolated from the worm uterus were exposed in vitro to methanolic extracts (ME) of nine plant species such as Achillea millefolium (AM), Artemisia absinthium (AA), Artemisia vulgaris (AV), Cicerbita alpina (CA), Cichorium intybus (CI), Inula helenium (IH), Origanum vulgare (OV), Tanacetum vulgare (TV), Tanacetum parthenium (TP). Flubendazole (FL), 0.5% formalin with dimethylsulfoxide and Petri dishes without the addition of reagents were used as positive, negative and untreated control respectively. The effects of the different ME at concentrations 0.500, 0.325, 0.200 mg/ml were assessed on the embryonic development (ED) of the eggs in duplicate. Logit analysis was used to calculate EC50 values. A generalized linear mixed model, having plant species and concentration as fixed effect and day as repeated measure, was used to determine differences in ED. Estimated EC50 was the lowest for FL at 0.11 mg/ml. CA and TV followed with 0.27 mg/ml and 0.32 mg/ml. ED for FL was significantly lower (25%) than that of CA (47%). The analysis showed 0.5 mg/ml of the ME of CA and TV significantly affected the ED at 35% and 42% inhibitions respectively. The ED for all ME showed similar pattern i.e., relatively higher efficacy in the first experimental week compared to the rest of the experimental period. The effect from all multicomponent extracts is time and dose dependent. The plants have promising results in inhibiting ED, contributing to the identification of alternative anthelmintic treatments.

Abstract
Limited pharmacological studies have been conducted on plant species used against poultry helminths. The objective of this study was to provide a basis for plant based anthelmintics as possible alternatives against poultry anthelmintic resistance. The study justified the need for alternative anthelmintics. The study places emphasis on the increasing anthelmintic resistance, mechanism of resistance, and preparational protocols for plant anthelmintics and their associated mechanism of action. Pharmaceutical studies on plants as alternative therapies for the control of helminth parasites have not been fully explored especially in several developing countries. Plants from a broad range of species produce a wide variety of compounds that are potential anthelmintics candidates. Important phenolic acids have been found in Brassica rapa L. and Terminalia avicenniodes Guill. and Perri that affect the cell signaling pathways and gene expression. Benzo (c) phenanthridine and isoquinoline alkaloids are neurotoxic to helminths. Steroidal saponins (polyphyllin D and dioscin) interact with helminthic mitochondrial activity, alter cell membrane permeability, vacuolation and membrane damage. Benzyl isothiocyanate glucosinolates interfere with DNA replication and protein expression, while isoflavones from Acacia oxyphylla cause helminth flaccid paralysis, inhibit energy generation, and affect calcium utilization. Condensed tannins have been shown to cause the death of nematodes and paralysis leading to expulsion from the gastro-intestinal tract. Flavonoids from Chenopodium album L and Mangifera indica L act through the action of phosphodiesterase and Ca2+-ATPase, and flavonoids and tannins have been shown to act synergistically and are complementary to praziquantel. Artemisinins from Artemisia cina O. Berg are known to disrupt mitochondrial ATP production. Terpenoids from Cucurbita moschata L disrupt neurotransmission leading to paralysis as well as disruption of egg hatching. Yeast particle encapsulated terpenes are effective for the control of albendazole-resistant helminths.

Abstract
Lysimachia ramosa has been used as a traditional medicine among the tribal population of Meghalaya, northeast India, for the control of helminthosis. The anthelmintic efficacy of L. ramosa has been documented earlier. In the present study, the active compound from L. ramosa has been isolated and identified using mass and NMR spectra. It's in vitro anthelmintic activity was evaluated against Raillietina echinobothrida, one of the most pathogenic cestode of domestic fowl. The isolated active compound was characterized to be a kaempferol derivative which showed potent anthelmintic activity against R. echinobothrida by changing surface ultrastructure and also inhibiting the activity of two neurotransmitter enzymes: acetyl cholinesterase (AChE) and nitric oxide synthase (NOS), both of which are known to perform dynamic roles in the intracellular communication mediated through neuromuscular system. Motility reduction, deformation in the surface architecture, extensive ultrastructural alterations and reduced histochemical stain intensity in both AChE and NOS was observed in the treated parasites. Biochemical result also revealed alteration in the enzyme activities in the treated parasites. Further, depletion in the nitric oxide (NO) production in the bioactive component exposed tissues of R. echinobothrida was also detected. The results provided evidence that the bioactive compound could be further explored to control helminthosis at a large scale.

Abstract
The leaf decoction of Sesbania sesban var. bicolor is used traditionally by Santhal tribe of Assam, India, for the treatment of intestinal helminthic infections. This study was conducted to evaluate the in vitro and in vivo anthelmintic efficacy of methanolic extract of S. sesban var. bicolor leaves using Hymenolepis diminuta-rat (cestode) and Syphacia obvelata-mice (nematode) as test parasites and models. Praziquantel (PZQ) and albendazole (ABZ) were used as reference drugs. At the highest concentration of 30 mg/ml of the plant extract, H. diminuta and S. obvelata showed mortality at 0.81 ± 0.01 h and 15.17 ± 0.05 h, respectively. The in vivo results substantiated the in vitro findings, and the extract showed a better cestocidal efficacy in a dose-dependent manner, whereby treatment of rats with 400 mg/kg of the plant extract caused 65.10% reduction in eggs per gram (EPG) of faeces and 56% reduction in worm counts. S. obvelata-infected mice treated at the same dose showed 34.32% and 47.08% reduction in EPG and worm counts at necropsy, respectively. The methanolic extract was subjected to bioassay-guided fractionation using different solvents and the ethyl acetate fraction proved to be the most active. This active fraction was subjected to column chromatography using varying concentrations of hexane:ethyl acetate. Maximum efficacy was observed in 7:3 hexane:ethyl acetate, where H. diminuta and S. obvelata showed mortality at 3.56 ± 0.12 h and 9.21 ± 0.02 h, respectively. This indicates that the isolated fraction contained the active component responsible for its anthelmintic activity, which substantiates the medicinal usage in traditional practice.

Abstract
Paramphistomosis is a pathogenic disease that occurs frequently in tropical and subtropical countries including Thailand. This disease is affected in the parasites causing severe gastrointestinal disorders and death in infected animals. In the present study, we examined the anthelmintic efficacy of albendazole (ABZ) and crude plant extracts from barks of Bombax ceiba L., Diospyros rhodocalyx Kurz. and Vitex glabrata R.Br., and leaves of Terminalia catappa L. and Cassia alata L. against Gastrothylax crumenifer. The hightest anthelmintic activity on the parasites after 24 h incubation was observed in the n-butanol extract of T. catappa leaf. In this study, fractionation bioassay of n-butanol extract of T. catappa leaf was conducted to both separation and discrimination of rutin served as a new efficient compound (LC50 = 28.96; LC90 = 88.75 μg/mL) against G. crumenifer. This compound was confirmed by 1H nuclear magnetic resonance (1H NMR), 13C NMR, infrared (IR) and ultraviolet (UV) spectra as well as mass spectra data. The rutin-treated parasites with all dosages showed swift decrease of the motility and the relative motility (RM) and survival index (SI) were decreased obviously from 3 h until flukes were killed after 12 h of incubation. When observed with light microscopy, the parasites showed the earliest change in a limited region of the tegument. When observed by scanning electron microscopy, the parasites' tegument exhibited similar sequences of surface changes after treatments with rutin and ABZ, but less severity in ABZ treatment. The sequences of changes comprised swelling of folds and ridges, formation of blebbing, rupturing of blebs, erosions, lesions and the tegument demolition. Hence, rutin could be considered as the potential anthelmintic agent for treatment of paramphistomosis.

Abstract
Medicinal plants have been successfully used in the ethno medicine for a wide range of diseases since ancient times. The research on natural products has allowed the discovery of biologically relevant compounds inspired by plant secondary metabolites, what contributed to the development of many chemotherapeutic drugs. Flavonoids represent a group of therapeutically very effective plant secondary metabolites and selected molecules were shown to exert also antiparasitic activity. This work summarizes the recent knowledge generated within past three decades about potential parasitocidal activities of several flavonoids with different chemical structures, particularly on medically important flatworms such as Schistosoma spp., Fasciola spp., Echinococcus spp., Raillietina spp., and model cestode Mesocestoides vogae. Here we focus on curcumin, genistein, quercetin and silymarin complex of flavonolignans. All of them possess a whole spectrum of biological activities on eukaryotic cells which have multi-therapeutic effects in various diseases. In vitro they can induce profound alterations in the tegumental architecture and its functions as well as their activity can significantly modulate or damage worm´s metabolism directly by interaction with enzymes or signaling molecules in dose-dependent manner. Moreover, they seem to differentially regulate the RNA activity in numbers of worm´s genes. This review suggests that examined flavonoids and their derivates are promising molecules for antiparasitic drug research. Due to lack of toxicity, isoflavons could be used directly for therapy, or as adjuvant therapy for diseases caused by medically important cestodes and trematodes.

Abstract
INTRODUCTION Paramphistomosis is a disease caused by the rumen flukes which cause an acute gastroenteritis and anemia with high mortality particularly in young ruminants. MATERIALS AND METHODS In this study, we have investigated the anthelmintic effect of medicinal plant extracts from leaves and heartwoods of Cassia siamea L., roots of Plumbago zeylanica L. and Plumbago indica L., and leaves of Terminalia catappa L. against Carmyerius spatiosus. RESULTS The highest anthelminthic effect on the flukes after 24 h of exposure was found in heartwood ethyl acetate extract of C. siamea (LC50 = 374.30; LC90 = 749.03 ppm), root n-butanol extract of P. zeylanica (LC50 = 1005.12; LC90 = 2411.55 ppm), root hexane, ethyl acetate, and n-butanol extract of P. indica (LC50 = 34.38, 211.34, 506.92; LC90 = 64.09, 496.05, 934.86 ppm), and leaf n-butanol and water extract of T. catappa (LC50 = 487.17, 470.28; LC90 = 913.27, 848.23 ppm). When observed by scanning electron microscopy, the tegument showed similar sequence of morphological changes after treatments with all plant extracts, comprising of swelling of ridges and folds, blebbing, rupturing of the blebs, erosion, lesion and disruption of the tegument. CONCLUSION This study is the first report on the anthelmintic activity of plant extracts to C. spatiosus; therefore, these plant extracts are highly effective in the elimination of adult rumen flukes.

Abstract
This study evaluated the antidiarrheal, analgesic, and anthelmintic activities of honey samples from the Sundarbans mangrove forest of Bangladesh. Composite raw honey (RH), and its diethyl ether (DEH), ethanol (ETH), methanol (MEH), and distilled water (DWH) fractions were investigated. RH and its fractions strongly inhibited castor oil-induced diarrheal episodes in mice at a concentration of 250 mg/kg body weight (b.w.) (P<0.05). At this concentration, RH, DEH, ETH, MEH, and DWH showed inhibitory activity on diarrheal episodes at 43.8, 47.4, 29.8, 12.3, and 38.5%, respectively, whereas for the inhibitory activity for the positive control (PC, 3 mg loperamide/kg b.w.) was 47.4%. Similarly, DEH (250 mg/kg b.w.) showed strongest inhibition (63.5%) of acetic acid-induced writhing in mice, followed by RH (55.7%), ETH (46.2%), MEH (37.6%), and DWH (32.9%). In a hot plate test, mice treated with DEH at a concentration 250 mg/kg b.w. showed the greatest increase in response time, followed by treatment with RH. RH was further used in an anthelmintic test, where it showed a strong dose-dependent reduction in both the paralysis time and the time until death of the parasite, Paramphistomum cervi. Honeys in the Sundarbans could therefore be of great use as nutraceuticals.

Abstract
Mesocestoides vogae larvae represent a suitable model for evaluating the larvicidal potential of various compounds. In this study we investigated the in vitro effects of three natural flavonolignans—silybin (SB), 2,3-dehydrosilybin (DHSB) and silychristin (SCH)—on M. vogae larvae at concentrations of 5 and 50 μM under aerobic and hypoxic conditions for 72 h. With both kinds of treatment, the viability and motility of larvae remained unchanged, metabolic activity, neutral red uptake and concentrations of neutral lipids were reduced, in contrast with a significantly elevated glucose content. Incubation conditions modified the effects of individual FLs depending on their concentration. Under both sets of conditions, SB and SCH suppressed metabolic activity, the concentration of glucose, lipids and partially motility more at 50 μM, but neutral red uptake was elevated. DHSB exerted larvicidal activity and affected motility and neutral lipid concentrations differently depending on the cultivation conditions, whereas it decreased glucose concentration. DHSB at the 50 μM concentration caused irreversible morphological alterations along with damage to the microvillus surface of larvae, which was accompanied by unregulated neutral red uptake. In conclusion, SB and SCH suppressed mitochondrial functions and energy stores, inducing a physiological misbalance, whereas DHSB exhibited a direct larvicidal effect due to damage to the tegument and complete disruption of larval physiology and metabolism.

Genistein: is the multifarious botanical a natural anthelmintic too? J Parasit Dis 2018; 42:151-161.

Abstract
Genistein (4',5,7-trihydroxyisoflavone) is naturally present in plants of the soy family and is known to have various pharmacological activities, such as anti-cancer, anti-diabetic, anti-oxidant, etc. The phytoestrogen is one of the major isoflavones found in some medicinal plants having anthelmintic properties. This review describes the putative role of genistein as an anthelmintic, which has been tested on some helminth parasites in vitro. Genistein has been shown to cause paralysis and alterations in the tegument and tegumental enzymes (acid phosphatase, alkaline phosphatase, adenosine triphosphatase, and 5'-nucleotidase) of helminth parasites. Alterations in the activities of several enzymes associated with the coordination system (specifically non-specific esterases, acetylcholine esterase, and nitric oxide synthase), and changes in the concentration of nitric oxide, cGMP, free amino acid pool, and tissue ammonia are observed in helminth parasites treated with genistein. The phytoestrogen also affects the carbohydrate metabolism by altering the activities of key enzymes involved in glycogen- and glucose-metabolism of a cestode parasite. Considering the significance of phosphoenolpyruvate carboxykinase (PEPCK) in glycolysis of the cestode parasite, Ki of the phytoestrogen for PEPCK in the parasite has been determined, and molecular docking of genistein into the active site of the enzyme has also been described. The potential beneficial role of genistein as a natural alternative in management of helminth parasites needs to be further explored, particularly considering its in vivo efficacy and pharmacokinetics.

Abstract
Pinworm infections are one of the common problems in laboratory rodents and man. At present there are only few drugs against intestinal helminths, and new drugs are urgently needed to cope up any future risk of drug resistance. Interest in plant secondary metabolites (PSMs) has risen considerably in the recent years for the discovery and development of new drugs. In the present study, we explored the in vitro and in vivo anthelmintic potentials of two pentacyclic triterpenoids, ursolic acid (UA) and betulinic acid (BA), the important PSMs of many medicinal plants, against Syphacia obvelata (Nematoda: Oxyuridae), a common pinworm of mice. The results of this study indicated that in both, in vitro and in vivo assays, BA showed comparatively better anthelmintic effects than UA. In the in vitro assay, 1.00 mg/ml concentration of BA showed paralysis and mortality of worms in 1.20 ± 0.04 and 2.30 ± 0.03 h, respectively. In the in vivo assay, a single 10.00 mg/kg dose of BA, administered for 5 days, revealed 68.78% reduction in egg counts and 84.08% reduction in worm counts of infected mice. The present study suggests that BA holds a great promise to be pursued further for detailed testing against some other representative group of helminth parasites.

Abstract
Schistosomiasis mansoni is considered one of the most common fibrotic diseases resulting from inflammation and deposition of fibrous tissue around parasitic eggs trapped in the liver, causing morbidity and mortality. Chemotherapy against schistosomiasis is largely dependent on Praziquantel (PZQ). Yet, the huge administration of it in endemic areas and its incompetence towards the immature stages have raised serious alarms against the development of drug resistance. Few drugs are directed to reverse schistosomal liver fibrosis, particularly at the chronic and advanced stages of the disease. Recently, protein tyrosine kinase (PTK) inhibitors have been identified as potent anti-schistosomal and anti-fibrotic drugs against schistosomes, that may suppress and reverse Schistosoma mansoni (S. mansoni) induced liver fibrosis. The present study was designed to assess the anti-schistosomal and antifibrotic activity of Genistein, a PTK inhibitor, in comparison to PZQ, on both acute and chronic S. mansoni-infected mice using different parasitological, histopathological and immunohistochemical studies. Genistein showed a significant reduction (P < .05) in total worm burden, tissue egg load, mean hepatic granulomas diameter and numbers, percentage of collagen and expression of transforming growth factor-beta 1 (TGF-β 1) in the examined hepatocytes with elevation in percentage of degenerated ova, in comparison to the control groups, in both acute and chronic stages of infection. The best results were obtained when Genistein was combined with PZQ. Therefore, it was concluded that Genistein showed a promising anti-schistosomal and anti-fibrotic properties which could make it one of the new potential targets in chemotherapy against schistosomiasis.

Abstract
SUMMARYAt present, there are no medicinal plant extracts currently available for treatment and control of fasciolosis. The present work could provide, for the first study, conclusions on the in vitro fasciolicidal properties of the ethanol extract of Terminalia catappa L. (TcCE) leaves against adult Fasciola gigantica after incubation with RPMI-1640 medium containing the TcCE at various concentrations and times when compared with triclabendazole (TCZ). The relative motility and survival index values of the TcCE-treated flukes decreased at a more rapid rate than the TCZ-treated flukes. The death of the parasites was observed after exposed to TcCE at 3 h incubation with 400, 800 and 1000 µg mL−1, and at 6 h incubation in 100 and 200 µg mL−1. Vacuolization, blebbings and partial disruption on the parasites’ tegument were observed by light microscopy. When examined by scanning electron microscopy, TcCE caused similar tegumental alterations in the parasites as those observed in TCZ treatment but with larger damage at comparative incubation periods, consisting of swelling, blebbing, disrupted blebs, loss of spines, leading to the erosion, lesion and eventual disruption of the total tegument. Therefore, the TcCE may exert its fasciolicidal effect against F. gigantica by initially causing the tegumental alteration.

Abstract
The leaves of Croton joufra have been used as a traditional medicine in Assam (Northeast India) to treat the intestinal helminthic infections. The aim of this study was to establish the in vitro and in vivo anthelmintic efficacy of the leaf extract of this plant on Hymenolepis diminuta, a zoonotic tapeworm. The plant extract was also screened for its chemical constituents. The in vitro anthelmintic efficacy of the plant was evaluated by physical motility test on adult cestodes, following their exposure to 10, 20, 30 mg/ml concentrations of the crude leaf extract, while the in vivo effect was determined based on the eggs per gram (EPG) counts and worm recovery rates, using an experimentally induced model of H. diminuta infections in Wistar rats. The in vitro study results showed a dose-dependent effect on the parasite and the highest concentration of the extract (30 mg/ml) caused mortality of the worms in 1.53 ± 0.12 h as compared to 3.46 ± 0.10 h shown by 1 mg/ml concentration of the reference drug, praziquantel (PZQ). The in vivo results showed that a single 800 mg/kg dose of the extract, given for 3 days, was highly efficacious against adult parasites as it reduced the EPG count and worm burdens of rats by 94.74 and 75 %, respectively. The extract also showed almost similar degree of effects against the larval stage of the parasite. As ascertained by the qualitative screening tests, the leaf extract of C. joufra contains terpenoids, tannins, alkaloids, flavonoids, glycosides and reducing sugar. The overall findings of this study suggest that C. joufra leaf extract possesses significant anthelmintic efficacy and support its traditional anthelmintic claims.

Abstract
Phosphoenolpyruvate carboxykinase (PEPCK) is involved in glycolysis in the cestode parasite, Raillietina echinobothrida; whereas, it executes a gluconeogenic role in its host, Gallus domesticus. Because of its differing primary function in the cestode parasite and its host, this enzyme is regarded as a plausible anthelmintic target. Hence, the biological significance of PEPCK in the parasite was analysed using siRNA against PEPCK from R. echinobothrida (RePEPCK). In order to find out the functional differences between RePEPCK and GdPEPCK (PEPCK from its host, G. domesticus), PEPCK genes from both sources were cloned, over-expressed, characterized, and some properties of the purified enzymes were compared. RePEPCK and GdPEPCK showed a standard Michaelis-Menten kinetics with K mapp of 46.9 and 22.9 µ m, respectively, for phosphoenolpyruvate and K mapp of 15.4 µ m for oxaloacetate in GdPEPCK decarboxylation reaction. Here, we report antagonist behaviours of recombinant PEPCKs derived from the parasite and its host. In search of possible modulators for PEPCK, few phytoestrogens were examined on the purified enzymes and their inhibitory constants were determined and discussed. This study stresses the potential of these findings to validate PEPCK as the anthelmintic drug target for parasitism management.

Abstract
The nematode, Haemonchus contortus, is responsible for major economic losses in the livestock industry. The management of parasites such as H. contortus has been through the use of synthetic parasiticides. This has resulted in the presence of residues in meat and milk, which affects food safety. The development of resistance to available anthelmintics coupled with their high cost has further complicated matters. This has led to the investigation of alternative methods to manage nematodes, including the use of plants and plant extracts as a potential source of novel anthelmintics. Acetone extracts were prepared from 15 South African plant species and their anthelmintic activity determined using the egg hatch assay (EHA). The leaf extract of Cleome gynandra had the best inhibitory activity (68% ± 3%) at a concentration of 2.5 mg/mL, followed by the stem extract of Maerua angolensis (65% ± 5%). The extracts had a relatively low toxicity on Vero cells determined by the MTT (3-(4,5-dimethylthiazol-2-yl)-2,5- diphenyltetrazolium bromide) cellular assay.

Abstract
SUMMARYPresently, no effective anthelmintic drugs have been used to treat and control paramphistomosis, a severe disease of ruminants. In this study, we have investigated thein vitroanthelmintic effect of the leaves ofTerminalia catappaL. crude extract (TcCE) and albendazole (ABZ) on adultFischoederius cobboldiafter incubating the flukes in RPMI-1640 medium containing the TcCE at various doses and times. The TcCE-treated flukes at all dosages exhibited rapid decrease of motility, and the relative motility (RM) values were decreased sharply from start to 3 h. Worms were killed after 6 and 12 h of treatment with 1000, 1500 and 2000µg mL−1as well as 500µg mL−1of TcCE, respectively. By light microscopy examination, the flukes exhibited the earliest alteration in a limited area of the tegument. At scanning electron microscopy level, the flukes’ tegument showed similar sequence of morphological alterations after treatment with ABZ and TcCE that consisted of swelling of ridges and folds, followed by blebbing and rupturing of the blebs, leading to the erosion, lesion and disruption of the tegument. Hence,in vivostudies should be performed to examine whether the TcCE may serve as a powerful anthelmintic drug for treatment of paramphistomosis.

Abstract
Cytosolic phosphoenolpyruvate carboxykinase (cPEPCK) is a critical enzyme involved in gluconeogenesis, glyceroneogenesis and cataplerosis. cPEPCK converts oxaloacetic acid (OAA) into phosphoenol pyruvate (PEP) in the presence of GTP. cPEPCK is known to be associated with type 2 diabetes. Genistein is an isoflavone compound that shows anti-diabetic and anti-obesitic properties. Experimental studies have shown a decrease in the blood glucose level in the presence of genistein by lowering the functional activity of cPEPCK, an enzyme of gluconeogenesis. Using computational techniques such as molecular modeling, molecular docking, molecular dynamics simulation and binding free energy calculations, we identified cPEPCK as a direct target of genistein. We studied the molecular interactions of genistein with three possible conformations of cPEPCK-unbound cPEPCK (u_cPEPCK), GTP bound cPEPCK (GTP_cPEPCK) and GDP bound cPEPCK (GDP_cPEPCK). Binding of genistein was also compared with an already known cPEPCK inhibitor. We analyzed the interactions of genistein with cPEPCK enzyme and compared them with its natural substrate (OAA), product (PEP) and known inhibitor (3-MPA). Our results demonstrate that genistein uses the mechanism of mixed inhibition to block the functional activity of cPEPCK and thus can serve as a potential anti-diabetic and anti-obesity drug candidate. We also identified an extended binding site in the catalytic cleft of cPEPCK which is used by 3-MPA to inhibit cPEPCK non-competitively. We demonstrate that extended binding site of cPEPCK can further be exploited for designing new drugs against cPEPCK.

Abstract
BACKGROUND Conventional plant-based therapies act as an important therapeutic tool for the treatment of worm infections all over the world and continuous evaluation of medicinal plants to find new potential lead compounds should be carried out. METHODS In-vitro analysis was conducted to evaluate the probable anthelmintic effect of crude aqueous and hydroalcoholic extracts of Ananas sativus leaves, Erythrina variegata barks and Alocasia indica rootstocks, against adult Paramphistomum cervi (Trematoda) and Haemonchus contortus (Nematode). RESULTS Among all three concentrations (25, 50, and 100 mg/mL), the hydroalcoholic leaf extract of A. sativus exhibited paralysis and death time ranged between 7.26 to 26.76 min and 15.40 to 35.55 min respectively for P. cervi while that for H. contortus was 14.70 to 42.43 min and 23.43 to 56.34 min, respectively. Moreover, aqueous extract exhibited paralysis and death time ranged between 7.66 to 28.72 min and 18.30 to 33.00 min, respectively, for P. cervi whereas paralysis and death time ranged between 23.34 to 37.88 min and 31.08 to 58.30 min respectively for H. contortus. Both extracts of E. variegata bark and A. indica tuber showed comparatively less significant anthelmintic activity. All results were statistically significant (p < 0.001). CONCLUSIONS A. sativus leaf displayed favorable anthelmintic activity on both P. cervi and H. contortus, whereas E. variegata barks and A. indica rootstocks showed insignificant result.

Abstract
α-Viniferin, an active component of the plant Carex baccans L., is known for its anticancer, antidiabetic, and anti-inflammatory properties. In Northeast India, different tribes traditionally consume C. baccans to control intestinal helminth infections. Therefore, the present study was carried out to assess the extent of tegumental alteration caused by α-viniferin in Raillietina echinobothrida, a widely prevalent poultry helminth in northeast India. Helminths were exposed in vitro to various doses of α-viniferin (50, 100, and 200 µM/mL of physiological buffered saline) and their motility and mortality were recorded. Stereoscan observations on the parasite exposed to the active compound showed extensive distortion and destruction of the surface fine topography of the tegument compared with controls. The compound also caused extensive damage to the tegument by disintegration of microtriches, disorganization of muscle bundles, and loss of cellular organelles combined with distortion and disruption of the plasma membrane, nuclear membrane, nucleolus, mitochondrial membrane, and cristae. Histochemical and biochemical studies carried out parasites exposed to α-viniferin revealed a decline in the activity of vital tegumental enzymes like acid phosphatase, alkaline phosphatase, and adenosine triphosphatase. Extensive structural and functional alterations observed in the treated parasites are indicative of efficient cestocidal activity of the compound.

Abstract
Pyruvate kinase (PK; EC 2.7.1.40) and phosphoenolpyruvate carboxykinase (PEPCK; EC 4.1.1.32) are essential regulatory enzymes of glucose oxidation in helminths, the PK/PEPCK branch point being the first divergent step between carbohydrate catabolism of the parasites and their hosts. Recently, PEPCK from the cestode parasite, Raillietina echinobothrida, has been purified and characterized. In order to find out the differential kinetics, if any, at PK/PEPCK branch point in the parasite, in this study, we purified and characterized the parasite PK and compared it with the parasite PEPCK. The purified PK displayed standard Michaelis-Menten kinetics with Kmapp of 77.8 µM for its substrate PEP, whereas the Kmapp was 46.9 µM for PEPCK. PEP exhibited differential kinetics at PK/PEPCK branch point of the parasite and behaved as a homotropic effector for PEPCK, but not for PK. The inhibitory constant (Ki) for genistein and daidzein (phytochemicals from Flemingia vestita) was determined and discussed. From these results, we hypothesize that PK/PEPCK branch point is a probable site for anthelmintic action.

Abstract
The present study have been conducted to evaluate the anthelmintic activity of crude aqueous and crude methanolic leaf extracts of Murraya koenigii. Infection of ruminants with gastro-intestinal (GI) parasite has become a worldwide problem. The parasite causes economic losses in a variety of ways. Previously sheep producers relied heavily on anti-parasitic drugs to control gastro-intestinal parasites of the flocks. But due to misuse of these drugs the parasites become resistant to drugs. Thus created interest in studying medicinal plants as an alternative source of controlling the GI parasites. Adult motility assay (AMA) and egg hatch assay (EHA) have been done for in vitro study, and faecal egg count reduction (FECR) assay have been done for in vivo study. The in vitro study revealed anthelmintic effects of M. koenigii on Haemonchus contortus as evident from their paralytic condition and/or death at eight hour post exposure in different concentrations (12.5, 25, 50 mg/ml) of aqueous and methanolic extracts which exhibit to be dose-dependent. Aqueous and methanolic extracts of M. koenigii were found to have low percent inhibitory effect on egg hatching. It may be concluded that M. koenigii showed significant anthelmintic activity.

Abstract
Exploring a green chemistry approach, this study brings to the fore, the anthelmintic efficacy of gold nanoparticles, highlighting the plausible usage of myconanotechnology. Gold nanoparticles of ∼6 to ∼18 nm diameter were synthesized by treating the mycelia-free culture filtrate of the phytopathogenic fungus with gold chloride. Their size and morphology were confirmed by UV-Vis spectroscopy, DLS data, AFM and TEM images. The XRD studies reveal a crystalline nature of the nanoparticles, which are in cubic phase. The FTIR spectroscopic studies before and after the formation of nanoparticles show the presence of possible functional groups responsible for the bio-reduction and capping of the synthesized gold nanoparticles. The latter were tested as vermifugal agents against a model cestode Raillietina sp., an intestinal parasite of domestic fowl. Further, ultrastructural and biochemical parameters were used to corroborate the efficacy study.

Abstract
BACKGROUND Musa seminifera Lour is a tree-like perennial herb that has been used in folk medicine in Bangladesh to heal a number of ailments. OBJECTIVE To evaluate the antioxidant, analgesic, antidiarrheal, anthelmintic activities, and general toxicity of the ethanol extract of the roots. MATERIALS AND METHODS The extract was assessed for free-radical-scavenging activity by the 2,2-diphenyl-1-picrylhydrazyl (DPPH) assay, total phenolic content (TPC) by the Folin Ciocalteu reagent, antioxidant activity by the ferric reducing power assay, analgesic activity by the acetic acid-induced writhing and hot-plate tests, antidiarrheal activity by the castor oil-induced diarrhea model in mice, anthelmintic activity on Paramphistomum cervi and Haemonchus contortus, and general toxicity by the brine shrimp lethality assay. RESULTS The extract showed free-radical-scavenging activity with an IC50 value of 44.86 μg/mL. TPC was 537.89 mg gallic acid equivalent/100 g of dried plant material. It showed concentration-dependent reducing power, and displayed 42.11 and 69.32% writhing inhibition at doses of 250 and 500 mg/kg body weight, respectively. The extract also significantly raised the pain threshold at the above-mentioned dose levels. In vivo antidiarrheal property was substantiated by significant prolongation of latent period and decrease in total number of stools compared with the control. The LC50 against brine shrimp nauplii was 36.21 μg/mL. The extract exhibited dose-dependent decrease in paralysis and death time of the helminths. CONCLUSION The above results demonstrated that the plant possesses notable bioactivities and somewhat supports its use in folk medicine.

Abstract
Paramphistomiasis causes enteritis and anemia in livestocks and result in substantial production and economic losses. It is considered a neglected tropical disease, with no effective trematodicidal compound for treatment. Plumbagin (PB), a compound founds to be rich in the roots of Plumbago indica, is a naphthoquinone derivatives which can induce oxidative stress in parasites. In this study we have evaluated the anthelmintic activity of PB against adult Paramphistomum cervi by incubating the parasites in M-199 medium containing 0.1, 1.0, 10 and 100 μg/ml of the PB, and albendazole (ABZ) at the concentration of 100 μg/ml as the positive control, for 3, 6, 12 and 24 h, using relative motility (RM) assay and observed by scanning electron microscopy (SEM). After 12 h exposure with 100 μg/ml ABZ, flukes showed decreased contraction and motility. At 24 h incubation they showed only active movement of some part of the body. The PB-treated flukes at all concentrations showed rapid decrease of motility at 3 h incubation. In 0.1, 1.0 and 10 μg/ml of PB, the RM values were decreased sharply from 3 to 12 h, and then they were killed since 12 h in the incubation with 10 μg/ml of PB. The highest parasite mortality was found as early as 3h when they were incubated with 100 μg/ml of PB. The morphological changes on the tegumental surface were similar in both flukes treated with ABZ and PB, which sequentially comprised of swelling, followed by blebbings that later ruptured, leading to the erosion and desquamation of the tegument syncytium. As the result, lesions were formed which exposed the basal lamina. The damage appeared more severe on the ventral than the dorsal surface, and earlier on the anterior part and lateral margins of middle third when compared to the posterior part of the parasites's bodies. The severity and rapidity of the damages were enhanced with increasing concentration of PB, which showed stronger activity than ABZ. Hence, PB has a potential to be an anthelmintic drug against adult P.cervi.

Abstract
SUMMARYPhosphoenolpyruvate carboxykinase (PEPCK, EC 4.1.1.32) is an essential regulatory enzyme of glycolysis in helminths in contrast to its role in gluconeogenesis in their host. Previously we have reported that phytochemicals from Flemingia vestita (Family: Fabaceae), genistein in particular, have vermifugal action and are known to affect carbohydrate metabolism in the cestode, Raillietina echinobothrida. In order to determine the functional differences of PEPCK from the parasite and its avian host (Gallus domesticus), we purified the parasite enzyme apparently to homogeneity, and characterized it. The native PEPCK is a monomer with a subunit molecular weight of 65 kDa. The purified enzyme displayed standard Michaelis-Menten kinetics with Km value of 42·52 μM for its substrate PEP. The Ki for the competitive inhibitors GTP, GMP, ITP and IMP for the carboxylation reaction were determined and discussed. In order to identify putative modulators from plant sources, phytochemicals from F. vestita and Stephania glabra were tested on the purified PEPCK, which resulted in alteration of its activity. From our results, we hypothesize that PEPCK may be a potential target site for anthelmintic action.

Abstract
The efficacy of Cassia alata against cestode Hymenolepis diminuta was evaluated in our study. Worms were maintained between rat model and beetle. Air-dried leaves of C. alata were subjected to ethanol extraction. Different concentrations (10-80 mg/ml) of the extract were prepared in phosphate buffer saline and tested on the parasite in vitro. Parasites treated with C. alata showed a decrease in motility with an increase in concentrations and complete immobilization took lesser time compared to control. The paralyzed parasites were further processed for electron microscopic studies. Ultrastructural micrographs revealed swelling of the tegument and blebbing on the tegumental surface throughout the body accompanied with destruction of microtriches and changes such as shrinkage in the scolex region. Depletion of parenchyma cells and destruction in the connective tissues along with sparsely cytoplasmic cytons were also observed, and these observations are similar with worms treated with a known drug praziquantel. These results may suggest that the plant leaves could be considered for controlling helminth infection and can represent a step forward in the search for alternative anthelmintic drug.

Abstract
Different species of Cassia plant are widely available in India and are commonly used either for their laxative, antimicrobial or antibacterial activity. In the present study the effectiveness in vitro of the crude alcoholic extracts of three species, namely Cassia alata, C. occidentalis and C. angustifolia, in the early paralysis and mortality of the fowl tapeworm Raillietina tetragona at concentrations ranging from 5 to 80 mg/ml was investigated. Time of paralysis and death were monitored frequently. Immediately after paralysis the tapeworms were processed for electron microscopic studies. While the untreated or control parasites survived for 81.93 ± 5.85 h, the parasites treated with C. alata took less time (1.68 ± 0.27 h) to be paralysed, followed by those treated with C. angustifolia (2.95 ± 0.29 h). Although C. occidentalis took more time (4.13 ± 0.31 h) to paralyse, in combination with either C. alata or C. angustifolia the time taken to paralyse became shorter. All the plant-treated parasites showed irrevocable changes in the scolex and proglottids as compared with the control, and these observations are comparable with those obtained with praziquantel. These results indicate that the three plants tested can be claimed to have anthelmintic activity in addition to their known properties, both when used individually and in combination. Further investigations will be required to evaluate their mechanism of action.

Abstract
The aqueous juice of the root extract of Carex baccans (Family: Cyperaceae) is used as an anthelmintic in Meghalaya, India. The present investigation was carried out to evaluate the extent of ultrastructural, histochemical and biochemical alterations caused by the plant derived component(s) on Raillietina echinobothrida, a cestode parasite of domestic fowl. Live tapeworms, collected from the freshly slaughtered host, were exposed to different concentrations of the crude ethanolic root extract of C. baccans for varying time durations. The treated parasites revealed complete inactivation and flaccid paralysis leading to death; they were processed for ultrastructural, histochemical and biochemical observations, as soon as paralysis set in. Compared to controls, the treated parasites showed extensive distortion and destruction of the surface fine topography of the tegument, erosion of microtriches, disruption of muscle layers, intense vacuolization of tegumental and subtegumental layers, swelling and vacuolization of mitochondria and a significantly reduced activity of tegumental enzymes like AcPase and AlkPase. Phytochemicals from the root of C. baccans seem to be effective against soft-bodied cestode parasites and need to be characterized and identified.

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
Alcohol and aqueous extracts from the roots of Baliospermum montanum Muell. Arg were investigated for their anthelmintic activity against Pheretima posthuma and Ascardia galli. Various concentrations (10-100 mg/ml) of each extract were tested in the bioassay, which involved determination of time of paralysis and time of death of the worms. Both the extracts exhibited significant anthelmintic activity at highest concentration of 100 mg/ml. Piperazine citrate (10 mg/ml) was included as standard reference and distilled water as control.

Abstract
Albendazole, a member of benzimidazole group of compounds, has been shown to have a broad spectrum activity against all classes of helminth parasites. Although it has also been experimentally proven to be effective against cestode infection of poultry, the actual effects of the drug are not yet described. The present in vitro study demonstrated that the commercial prescription drug Zentel® was significantly effective against adult Raillietina echinobothrida Mégnin, the major cestode parasite of domestic chicken, Gallus domesticus Linnaeus. It clearly exhibited dose-dependent lethal activity at the different concentrations that were tested. Scanning electron microscopy (SEM) revealed that the drug caused extensive structural alterations on the body surface of the cestode. Severe contraction and shrinkage were evident throughout the entire length of the body. The suckers on the scolex became invaginated due to shrinkage. The distinct body segments, the proglottides, were completely distorted. The fine hairy microtriches on the tegument were obliterated and in its place were formed abnormal clumps of tissues. The results of this investigation are in favor of the use of albendazole as a drug of choice in the management of poultry helminthiasis.

Antiparasitic activity of methanolic extract of Acacia oxyphylla (Leguminosae) against Raillietina echinobothrida. J Parasit Dis 2011; 34:14-9. [PMID: 21526027 DOI: 10.1007/s12639-010-0001-8] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.1] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/02/2010] [Accepted: 05/31/2010] [Indexed: 10/19/2022] Open
Abstract
Acacia oxyphylla has been used traditionally by the natives of Mizoram against intestinal worm infections. In the present study, the crude methanolic extract of the plant was tested in vitro on the cestode parasite Raillietina echinobothrida to evaluate its potential anthelmintic efficacy. The test parasites were exposed to varying concentrations of the plant extract in phosphate buffered saline and they all slipped into a flaccid paralytic state at varying periods of time post incubation. Ultrastructural observations on the paralysed worms revealed wide scale destruction of the parasite tegument with intense vacuolization of the syncytium and swellings of the basal lamina accompanied by deformities in the cell organelles. To determine the exact mode of action of the botanicals on the parasite body surface, the tegumental enzymes viz. acid phosphatase (AcPase), alkaline phosphatase (AlkPase) and adenosine triphosphatase (ATPase) were investigated. A prominent decrease in the phosphatase activity, in comparison to the untreated control parasites was noticeable. In view of the alterations in the structural and functional integrity of the tegument, occurring in the treated parasites, it may be assumed that the changes transpire because of a compromise in the permeability of the tegument under the influence of the test plant-derived active chemical principles.

Abstract
In the present study, chloroform, aqueous, (polyethylene glycol/propylene carbonate) PEG/PC extracts were made from coconut, onion, garlic, fig, date tree, chicory, ananas, and cistrose. These extracts were tested in vivo and in vitro on their anthelmintic activity against cestodes (Hymenolepis diminuta, H. microstoma, Taenia taeniaeformis) and trematodes (Fasciola hepatica, Echinostoma caproni). In all in vitro tests, the target parasites died. It turned out that the treatment of mice and rats with a combination of onion and coconut extracts (with PEG/PC) eliminated all cestodes from their final hosts. In addition, the same composition was effective against the intestinal fluke E. caproni, but not against the liver fluke F. hepatica in the final host, while both worms were killed in vitro. Inoculation of fluids of coconut eliminated T. taeniaeformis tapeworms from naturally infected cats. This goal was not reached with oil of cistrose.
