The anthelminthic efficacy of the crude extracts of Hypoestes forskaolii (Vahl) R.Br (Acanthaceae) against gastrointestinal nematodes (GIN) in sheep was investigated using the in vitro egg hatch inhibition assay. Faecal samples were collected from sheep with naturally occurring infection of GIN (Trichostrongylus spp., Chabertia ovina, Cooperia spp., Haemonchus contortus and Teladorsagia spp.). Crude leaf extracts of H. forskaolii was obtained using increasing polarity solvents: n-hexane, chloroform, chloroform:methanol 9:1, methanol. Thiabendazole (0.2 µg/mL and 0.5 µg/mL) was used as a positive control and untreated GIN eggs in deionised water served as the negative control. All the extracts exhibited a weak ovicidal activity against GIN (less than 50% of egg hatch). Noteworthy, the n-hexane extract showed a percentage of inhibition of egg hatching greater than other extracts inhibiting the 30.8% at the concentration of 1 mg/mL showing a dose-dependent effect on nematode eggs hatching. Further studies are needed to investigate the effects of extracts used and to evaluate the ovicidal effects of other extracts of H. forskaolii.

With the aim to find new effective natural compounds for the control of nematodes, the in vitro anthelminthic properties of purified 1% saponins showing different chemical compositions and derived from Medicago sativa (MS), Medicago arborea (MA), Medicago polymorpha cultivar ‘Santiago’ (MPS), M. polymorpha cultivar ‘Anglona’ (MPA), and 1% prosapogenins from M. sativa (MSp), were evaluated and compared. As a source of nematode eggs, pooled fresh fecal samples taken from dairy donkeys naturally infected by gastrointestinal nematodes were used. From fecal samples, eggs were recovered, suspended in deionized water, and used immediately in the bioassay (egg hatch test). The activity of the tested compounds was compared to positive (0.1% thiabendazole) and negative (deionized water and 1% DMSO) controls. All experiments were repeated in triplicate and the obtained data were statistically analyzed. All the tested plant compounds caused a significant (p < 0.05) inhibition of nematode egg hatching (>80%). Moreover, all saponins and prosapogenins showed in vitro anthelmintic properties statistically comparable to that of the reference drug (p < 0.05), except for MPS extract. Obtained results showed that the different Medicago saponins evaluated in this study possess high anthelmintic properties against gastrointestinal nematodes of dairy donkeys, although to a different extent depending on their composition.

AbstractThis study assessed the anthelmintic activity of plant-derived compounds against gastrointestinal nematodes of goats using the egg hatch and larval motility assays. The compounds tested were saponins (digitonin and aescin) and their respective sapogenins (aglycones), hecogenin acetate and flavonoids (catechin, hesperidin, isocordoin and a mixture of isocordoin and cordoin). Additionally, cytotoxicity of active substances was analysed on Vero cell through 3-4,5-dimethylthiazol-2-yl,2,5diphenyltetrazolium bromide (MTT) and propidium iodide (PI) tests. Significant reduction on the egg hatching (P < 0.05) was seen only in the treatments with aescin (99%/EC50 = 0.67 mg mL−1) and digitonin (45%). The compounds that reduced the larval motility (P < 0.05) were digitonin (EC50 = 0.03 mg mL−1 and EC90 = 0.49 mg mL−1) and the hecogenin acetate (75%). The other sapogenins showed low anthelmintic activity. All the flavonoids showed low ovicidal (4–12%) and larvicidal (10–19%) effects. The aescin and digitonin showed low toxicity in PI test (viable cells >90%). Nevertheless, higher cytotoxicity was observed in the MTT assay, with IC50 of 0.20 mg mL−1 (aescin) and 0.0074 mg mL−1 (digitonin). Aescin and digitonin have a pronounced in vitro anthelmintic effect and the glycone portion of these saponins plays an important role in this activity.

The in vitro anthelmintic activity on sheep gastrointestinal strongyle (GIS) eggs and larvae of 0.5% aloin and 0.1% aloe-emodin was investigated. From fresh faecal samples collected by ewes naturally infected by Haemonchus, Trichostrongylus and Teladorsagia nematodes, GIS eggs were isolated and cultivated in Petri dishes (100 eggs/dish). For the in vitro evaluation of the anthelmintic activity of tested compounds, the Egg hatch test (EHT), the Larval development test (LDT) and the Larval mortality/paralysis test (LMT) were used. In each assay, the activity of tested compounds was compared to untreated and treated (0.1% thiabendazole, TBZ) controls. Six repetitions were made through the experiment. Obtained data were statistically elaborated using the X2 test. In EHT, 0.5% aloin gave highly significantly different (P<0.01) results from the untreated controls. In LDT, both 0.1% aloe-emodin and 0.5% aloin almost completely prevented the larval development from L1 to L3, showing no significant differences (P<0.01) when compared to TBZ. In LMT, larval mortality observed in 0.5% aloin treated plates was significantly higher (P<0.01) than that observed in TBZ treated controls. These results show the in vitro anthelmintic properties on sheep GIS of the examined plant secondary metabolites. In LDT and/or LMT, the activity of 0.5% aloin and 0.1% aloe-emodin was comparable to or higher than that of the reference drug.

The objective of this study is to evaluate the effect of dry wormwood and mallow on the gastrointestinal parasite of small ruminants Haemonchus contortus. Twenty-four experimentally infected lambs were randomly divided into four groups of six animals each: unsupplemented lambs, lambs supplemented with wormwood, lambs supplemented with mallow and animals supplemented with a mix of both plants. Faecal samples from the lambs were collected on day 23, 29, 36, 43, 50, 57, 64 and 75 post-infection for quantification of the number of eggs per gram (EPG). The mix of both plants contained phenolic acids (10.7 g/kg DM) and flavonoids (5.51 g/kg DM). The nematode eggs were collected and in vitro egg hatch test was performed. The aqueous extracts of both plants exhibited strong ovicidal effect on H. contortus, with ED50 and ED99 values of 1.40 and 3.76 mg/mL and 2.17 and 5.89 mg/mL, respectively, in the in vitro tests. Despite the great individual differences between the treated lambs in eggs reduction, the mean EPG of the untreated and treated groups did not differ (p > 0.05). Our results indicate that using wormwood and mallow as dietary supplements do not have a sufficient effect on lambs infected with H. contortus.

Because of the development of resistance in helminths against major anthelmintic drugs, the search for alternatives is necessary. Medicinal plants are being studied as an alternative source of anthelmintics against gastrointestinal nematodes. The objective of this study is to analyse the chemical composition and evaluate the anthelmintic efficacy of Origanum majorana essential oil. The determination of the chemical composition by gas chromatography/mass chromatography (GC/MS) revealed that the essential oil was dominated by terpenoids, particularly carvacrol (35.65%) and terpenic hydrocarbons p-cymene (15.82%). The in vitro anthelmintic effects against Haemonchus contortus were assessed by an egg hatch assay (EHA) and an adult worm motility assay (AWMA) compared with the reference drug albendazole. The essential oil showed ovicidal activity at all the tested concentrations (1, 2, 4 and 8 mg/ml) and more than 80% egg hatching inhibition was observed at the highest dose (8 mg/ml). Exposure to 0.5 mg/ml of the essential oil for eight hours induced a 50% inhibition in the worm motility. The in vivo study was performed on H. polygyrus by measuring the egg count reduction (ECR) and adult worm count reduction (AWCR) following the treatment of the animals with different doses (2 000, 4 000 and 5 000 mg/kg) of the plant essential oil, and 22 mg/kg of albendazole as the positive control. The results showed that 5 000 mg/kg of the essential oil inhibited the egg count and adult worm count by 76.3 and 74.0%, respectively, seven days post treatment. These findings support the possible use of O. majorana essential oil to control gastrointestinal nematodes.

This study was conducted to evaluate the potential anthelminthic properties of extracts of leaves of indigenous browses (Acacia seyal, Acacia senegal, Acacia tortilis, Millettia ferruginea, and Vernonia amygadalina) based on three in vitro assays. Acetone extracts of browses at different concentrations (75 to 1200 μg/ml, for egg and larvae and 100mg/ml for an adult) were tested on three developmental stages of Haemonchus contortus (eggs, infective larvae, and adult worms) using egg hatch assay (EHA), larval migration inhibition assay (LMIA) and adult worm motility inhibition assay (AMIA). Significant effects were obtained with all five browses but differences were observed depending on the parasitic stages. The effects of five browse extracts on egg hatching were concentration-dependent, the highest (P<0.05) egg hatch inhibition rate was observed at 1200 μg/ml concentration for all browses. All extracts had a higher effect (P<0.01) than that of the negative control, phosphate buffer saline (PBS). In contrast, no concentration-response relationship was found for infective larvae and adult worms, although more potent effects were observed with the highest concentrations. The LMI rate (70%) induced by Vernonia  amygadalina extract, at a concentration of 300 μg/ml, was the highest (P<0.05) of all other browses, even at higher concentrations. The highest LMI rate (62%) induced by Acacia senegal extract at higher concentration, was lower than that of LMI rate (70%) induced by Vernonia amygadalina, at 300 μg/ml concentration. Vernonia amygadalina was found to be highly and rapidly effective against adult worms inducing the highest mortality rate (90%) as soon as 4 hrs after incubation. Overall, the in vitro results suggest that these five  browses do possess anti-parasitic properties and Vernonia amygadalina showed the most effective anti-parasitic property. These effects remain to be confirmed through in vivo study.

Background: Gonorrhea cases experiencing antibiotic resistance are increasing due to inadequate treatment or failure to contribute to an increase in antibiotic resistance cases; WHO suggests adding herbal therapy treatment methods is expected to minimize the occurrence of drug resistance as much as possible. Previous studies that have been carried out using other herbal plants have not shown any potential to inhibit the growth of Neisseria gonorrhoeae bacteria, seen from the amount of extract concentration and the dosage and content of the compounds in the contents monitoring the time.Objective: To analyze the difference in the effect of various concentrations of Matoa Leafs Extract (Pometia Pinnata) compared to 500mg Levofloxacin on the increase in the growth inhibition of Neisseria gonorrhoeae.Methods: This is true-experimental research with a post-test-only control group with a randomized design. The sample in this study was the microorganism Neisseria gonorrhoeae obtained through vaginal swabs in 2 females (FSW) positive for Gonorrhea by gram staining and microscopic examination and culture on Chocolate Agar Plant (CAP) media. The culture was then suspended in CAP media. Matoa Leaf extract concentration of 100%, 80%, 60%, 40%, 20%, positive control with Levofloxacin 500 mg and negative control with distilled water with four replications and monitoring in 24 hours, 48 hours, 72 hours, and 96 hours. Data analysis used Kruskal-Wallis, Mann-Whitney, and cohen's test. Result: Levofloxacin 500mg in inhibiting Neisseria Gonorrhoeae bacteria is very effective, and Matoa Leaf extracts 60% and 40% P=0,026 have a strong enough potential to inhibit the growth of Neisseria gonorrhoeae bacteria with the same potential strength. The cohen's test 1.4 effect the levofloxacin 500mg provides a significant influence inhibiting Neisseria Gonorrhoeae.Conclusion: Matoa Leaf extract 60%, and 40% have solid antibacterial potential, although not as strong as Levofloxacin 500mg.
