A phytochemical screening and in vitro anthelminthic activity of aqueous and ethanolic extract of Senna italica on Haemonchus contortus were conducted. Polyphenol, tannin and flavonoid contents were determined by using gallic acid and rutin. egg hatching inhibition test was carried out on fresh eggs; larval mortality test was conducted on infective larvae (L3) and adult worm mortality test was conducted. Eggs, larvae and adults worms were incubated in aqueous and ethanolic extract of S. italica at different concentrations (0.1; 0.3; 0.5; 0.7 and 1 mg/mL). All extracts of plants showed an effect on all stages of H. contortus with high efficiency variations depending on the dose used. The inhibition of eggs hatching rate increased from 8.67±1.53% to 65.67±1.15% and from 24.67±1.53% to 80±1.73% respectively for aqueous and ethanolic extract of S. italic. The larval mortality rate increased from 12.22±2.34% to 56.67±4.9% after 24 h and from 45.28±4.11% to 91.25±3.73% after 48 h for aqueous extract and from 30.07±2.84% to 70.83±6.31% after 24 h and from 48.79±3.73% to 96.25±4.79% after 48 h for ethanolic extract. After 24 h of exposure to aqueous and ethanolic extract of S. italica, the adult mortality rate varies from 55.56±9.62% to 83.33±9.62% for aqueous extract and from 61.11±9.62% to 88.89±9.62%.These in vitro results confirm the use of S. italica in traditional medicine.

Gastrointestinal nematode causes significant production losses in grazing ruminants and anthelmintic resistance are increasing at an alarming rate. The aim of this study was to evaluate the in vitro anthelmintic effects of tannin-containing plant Artemisia vulgaris against stomach worm Haemonchus contortus of goat. In this respect, in vitro anthelmintic activities of crude aqueous and ethanolic extracts of aerial parts of A. vulgaris were investigated on eggs, larvae (L3) and adults of H. contortus in the laboratory. Experimental plant Artemisia was collected, dried in shade and grinded to coarse powder and subjected to prepare crude aqueous and ethanolic extract. The experiment revealed that crude ethanolic extracts completely inhibited egg hatching at concentration of 5 mg/ml whereas aqueous extracts at concentration of 10 mg/ml. After exposure of 8 hours, the crude ethanolic extracts inhibited 69.33%, 51% and 38% larval motility tested at 20 mg/ml, 10 mg/ml and 5 mg/ml concentrations, respectively while the crude aqueousextracts inhibited 57.33%, 48.67% and 34.67% at the same concentrations. The ethanolic extract showed better in vitro effects against adult stomach worm than the aqueous extract in terms of motility inhibition at different hours post-treatment. Dose dependent effects were also observed for both extract. After 2 and 8 hours of exposure, the ethanolic extract induced 53.33% and 100% mortality at the highest tested concentration respectively, while the aqueous extract induced 47.67% and 86.67% at the same concentration. To our best knowledge, this is the first study in Bangladesh on the in vitro anthelmintic effects of A. vulgaris against H. contortus. Further in vitro and in vivo trials with this plant are required to evaluate their anthelmintic effects precisely. J Bangladesh Agril Univ 17(3): 363–368, 2019

Gastrointestinal nematodes (GINs) are the major limiting factor for the successfulness of livestock production throughout the world. Emergence of resistance strains as well as scarcity and high cost of the currently available drugs has led to the evaluation of other alternative helminth control options, mainly from plants. The current study is aimed at investigating the in vitro anthelmintic efficacy of crude methanolic extracts of two traditionally important medicinal plants, Artemisia herba-alba and Punica granatum, against Haemonchus contortus using adult motility assay (AMA) and egg hatch inhibition assay (EHIA). Four graded concentrations of the extracts were tested for both the AMA (10, 5, 2.5, and 1.25 mg/mg) and EHIA (0.1, 0.25, 0.5, and 1 mg/mL) in replicates. Albendazole and phosphate-buffered saline (AMA) or distilled water (EHIA) were used as the positive and negative controls, respectively. The crude extracts of A. herba-alba and P. granatum exhibited a potential anthelmintic activity at all dose levels in a concentration- and time-dependent fashion. The highest concentration (10 mg/mL) of all the extracts caused a significantly (p<0.05) superior nematocidal activity compared to the negative control. Moreover, significant and concentration-dependent egg hatching inhibition effect was observed from both plant extracts. Maximal (98.67%) egg hatching inhibition effect was exhibited by the flower extract of A. herba-alba at 1 mg/mL concentration. The relative egg hatch inhibition efficacy indicated that both plants caused a significantly (p<0.05) greater egg hatch inhibition within 48 hr of exposure. The current study validated the traditional use of both plants as a natural anthelmintic against H. contortus justifying a need to undertake detail pharmacological and toxicological investigation on both plants.

Haemonchus contortus affect small ruminants all over the world. Anthelmintics cause resistance, contamination, and a risk of public health. Prosopis laevigata is a plant used as a home remedy against many diseases in Mexico. This study arose from a preliminary study where a P. laevigata hydroalcoholic extract (Pl-hae) showed anthelmintic activity (aa) against H. contortus. Searching for bioactive compounds (bac) with high aa, the Pl-hae was fractioned obtaining an aqueous (Aq-F) and an ethyl acetate fraction (EtAc-F), and a flavonoid with aa identified as isorhamnetin was obtained from EtAc-F. Both fractions were in vitro assessed by the egg hatch test (eht) and larval mortality (lm) assays. The bac obtained from EtAc-F were characterised by NMR analysis. The highest aa were recorded with EtAc-F, resulting in 100% eht and 80.45% lm at 0.75 and 30 mg/mL, respectively. Alterations in eggs and larvae attributed to isorhamnetin were recorded by environmental scanning electron microscopy, confocal laser scanning and by high-resolution digital-coupled camera. This flavonoid caused 100% eht at 0.07 mg/mL after 48 h and 100% lm at 7.5 mg/mL after 72 h exposure. Isorhamnetin has promising potential as an anthelmintic against sheep haemonchosis.

Parasitic nematodes are of major economic importance in livestock. An alternative for the control of parasites is phytotherapy. This study evaluated the efficacy of Cymbopogon citratus decoction (CcD), C. citratus essential oil (CcEo) and citral against Haemonchus contortus using in vitro egg hatch test (EHT) and larval development test (LDT) and an in vivo test using a Meriones unguiculatus (gerbil) model. The effect of 800 mg/kg CcEo was evaluated in gerbils that had been artificially infected with 5,000 third-stage H. contortus larvae. The effective concentrations required to inhibit 50% (EC50) of egg hatching were 0.46, 0.14 and 0.13 mg/mL for CcD, CcEo and citral, respectively. The EC50 values in the LDT were 5.04, 1.92 and 1.37 mg/mL for CcD, CcEo and citral, respectively. H. contortus population in the group treated with C. citratus essential oil was reduced by 38.5% (P< 0.05) in comparison to the control group. These results suggest that it may be possible to use C. citratusessential oil to control of H. contortus parasite of small ruminant.

Background. Haemonchus contortus, the causative agent of Haemonchosis, is the most economically important parasite in small ruminant production. Control with chemotherapy has not been successful due to rapid emergence of drug-resistant strains. There is a continuous search for alternative leads particularly from plants. The study aimed to evaluate the anthelmintic activity of crude methanolic extracts of leaves of Schinus molle and aerial parts of Cissus quadrangularis against H. contortus. Methods. Adult motility test and egg hatching inhibition assay were employed to investigate the in vitro adulticidal and egg hatching inhibitory effects of the extracts. Results. Higher concentrations of the extracts (10 and 5 mg/ml) had a significantly superior adulticidal activity (p<0.05) compared to the negative control and lower concentration levels, which was comparable to albendazole. Similarly, the relative egg hatch inhibition efficacy of S. molle and C. quadrangularis extracts indicated a maximum of 96% and 88% egg hatch inhibition, respectively, within the 48 hrs of exposure at 1 mg/ml. Conclusion. The current study evidenced that the crude methanolic extracts of the plants have promising adulticidal and egg hatching inhibitory effects against H. contortus.

Abstract The development of host resistance to anthelmintics and the increasing cost of commercial anthelmintics have encouraged the need for the in vitro anthelmintic evaluation of crude extract and fractions of Hymenodictyon pachyanta plant as alternative drugs against Haemonchus contortus. H. contortus is one of the most prevalent and highly pathogenic parasitic nematodes in small ruminant farming globally. H. pachyanta stem bark is a prospective plant used by the local and indigenous farmers of Nsukka, Enugu state, Nigeria. The stem bark of H. pachyanta were collected, dried, pulverized and extracted with 80 % methanol. The purpose of this study was to investigate the in vitro anthelmintic effects of these crude extract and fractions against H. contortus in sheep and goats. The two extracts (crude and fractions) of H. pachyanta were tested by the egg hatch assay (EHA) and the larval development inhibition assays (LDIA) and to compared the results with albendazole (as the positive control). The concentrations for the crude extract and albendazole used for this study were 0.78, 1.56, 3.125, 6.25 and 12.5 mg.ml−1. The results demonstrated that the crude extracts, fractions and albendazole all at the concentration doses of 12.5 mg.ml−1 produced 100 % inhibition of egg hatching and larval development. Statistically, there was no significant difference (P > 0.05) in the mean percentage inhibition of egg hatching and larval development inhibition of the crude extracts and fractions when compared with albendazole. However, a significant difference (P < 0.05) was observed with n-butanol fraction which inhibited 96.17 % of egg hatchability. All of the extracts and albendazole showed ovicidal and larvicidal effects and were able to induce over 50 % of the egg hatching and mortality of larvae at the concentration ranges of 0.78—12.5 mg.ml−1. The results obtained from our study suggest that H. pachyanta had ovicidal and larvicidal activity against H. contortus and that the bioactive plants compounds responsible for this effect could be attributed to the presence of tannins, alkaloids and the saponins contained in the crude extracts.

AbstractThe in vitro larvicidal and in vivo anthelmintic effects of Oxalis tetraphylla hydroalcoholic extract (HE), against Haemonchus contortus in experimentally infected lambs, were assessed. We used a microtitration plate method, comprising the following two stages. Stage 1: 20 μl of water containing 200 sheathed H. contortus infective larvae (ShHcl) were deposited in every well of three series; then, the series 2 and 3 wells were treated with 80 μl 1% ivermectin and O. tetraphylla HE at 20 mg/ml, respectively. Stage 2: the same procedure was performed replacing the ShHcl with exsheathed larvae (ExShHcl). Evaluations were performed after 24 and 48 h. The total numbers of dead and live larvae were counted. A second experiment evaluated the reduction in nematode egg populations in the faeces of lambs treated orally with the O. tetraphylla HE. The 27 lambs used were divided into Groups 1, 2 and 3 (n = 9), which were administered water (positive control), levamisole 1 m (7.5 mg/kg body weight (BW), as a unique dose) and O. tetraphylla HE (20 mg/kg BW), respectively. The plant HE was administered daily for 8 days. The in vitro assay showed 80.9% and 86.5% larval mortality of ShHcl after 24 and 48 h, respectively, while the corresponding mortality values for ExShHcl were 97 and 99%, respectively. The in vivo assay showed variability in the eggs/gram of faeces (epg) values; however, at the end of the trial, the average reduction in the epg values of the O. tetraphylla HE group was 45.6% (P < 0.05). Oxalis tetraphylla HE contains compounds that belong to the flavonol group with anthelmintic activity.

Background: Cleome rutidosperma is annual herb found in different places in Bangladesh. Its leaves used as the treatment for Helminthiasis associated with Haemonchus contortus. This parasite is one of the most pathogenic nematodes and responsible for anemia, edema, and death of cattle’s, mainly during summer in warm, humid climates as like Bangladesh. The aim of the study to investigate the in-vitro anthelmintic activity of aqueous extract C. rutidosperma (AECR) leaves against H. contortus. Methods: We performed phytochemical analysis and in-vitro anthelmintic assay to determine the possible phytochemicals, caused by anthelmintic activity against H. contortus. Results: In-vitro anthelmintic assay, the AECR at the doses of 25; 50 and 100mg/mL significantly (p< 0.01) and (p< 0.001) paralyzed and caused the death of H. contortus in a dose-dependent manner. Reference standard drug Albendazole (15 mg/mL) exerts almost same effect as AECR. No paralyzed and death observed at the control group when treated with 0.9% normal saline. Conclusion: This data confirmed that the aqueous extract C. rutidosperma has the in-vitro anthelmintic activity of against H. contortus. C. rutidosperma may offer an alternative source for the control of gastrointestinal nematodes of cattle’s.
