Abstractα-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.

Parasites (protozoa, helminthes, arthropods) represent a main threat for poultry worldwide. Among helminthes, nematodes constitute the most important group of parasites of poultry. The nematode Ascaridia galli, the cause of ascaridiosis in poultry, is one of the most important and prevalent parasites, resulting in serious economic losses, associated with the treatment cost, the decreased feed efficiency, and the poor egg and meat production. During the past few decades the indiscriminate use of anthelmintic drugs has generated several cases of resistance in helminthes in poultry, situation which is coupled with the severity of residues in poultry products. For this reason, nowadays attention has been drawn to the use of botanicals in poultry diet, due to their anthelmintic properties. Furthermore, the dietary use eco-friend ly of these plant derived substances compared to conventional synthetic anthelmintic drugs is considered as a natural and ecofriendly approach by the consumers. The focus of the present review is to recapitulate the studies, both in vivo and in vitro, that have demonstrated the anthelmintic efficacy of various dietary botanicals in controlling poultry ascaridiosis.

Pharmaceutical effluents collected from Bompai industrial area, Kano State were assessed for their physiochemical parameters, heavy metals and effect on haematology and biochemical changes in Clarias gariepinus. Laboratory analyses were performed using standard methods in a Completely Randomized Design (CRD). Five test solutions of the effluents (0, 25, 50, 75, and 100% v/v) were prepared for LC50 96hr acute toxicity test. The LC50 for 96hr was 48.7% concentration of effluents by volume. Experimental fish were exposed to sublethal concentrations of 0.00% 2.43% (5/100 LC50), 12.17% (25/100 LC50), 24.35% (50/100 LC50) and 36.52% (75/100 LC50) for 28days.  Physicochemical parameters recorded were higher than WHO recommended Standard with the exception of water temperature. Heavy metals concentrations decreased in the order of Cr > Cu > Pd > Cd. Red blood Cells count, haemoglobin concentrations, packed cell volume, lymphocytes and monocytes of the experimental fish decline significantly (p<0.05) when exposed with 2.43, 12.17, 24.35, 36.52% effluents  compared to the control. White blood cell count, mean corpuscular haemoglobin, mean corpuscular volume, mean corpuscular haemoglobin concentrations, neutrophils and eosinophils were significantly higher (P<0.05) than the control. However, a significant increase (P<0.05) in the activities of serum aspartate aminotransferase (AST), Alkaline Phosphatase (ALP) and alanine aminotransferase (ALT) were recorded as the exposure period continued when compared with control. It is concluded that the effluents induces haematological and biochemical alterations. It is therefore recommended that regulatory bodies should adopt holistic approach on the aquatic pollution abatement, bearing in mind the negative impact to non-target organisms.

AbstractThe in vitro nematicidal effect of Chenopodium ambrosioides and Castela tortuosa n-hexane extracts (E-Cham and E-Cato, respectively) on Haemonchus contortus infective larvae (L3) and the anthelmintic effect of these extracts against the pre-adult stage of the parasite in gerbils were evaluated using both individual and combined extracts. The in vitro confrontation between larvae and extracts was performed in 24-well micro-titration plates. The results were considered 24 and 72 h post confrontation. The in vivo nematicidal effect was examined using gerbils as a study model. The extracts from the two assessed plants were obtained through maceration using n-hexane as an organic agent. Gerbils artificially infected with H. contortus L3 were treated intraperitoneally with the corresponding extract either individually or in combination. The results showed that the highest individual lethal in vitro effect (96.3%) was obtained with the E-Cham extract at 72 h post confrontation at 40 mg/ml, followed by E-Cato (78.9%) at 20 mg/ml after 72 h. The highest combined effect (98.7%) was obtained after 72 h at 40 mg/ml. The in vivo assay showed that the individual administration of the E-Cato and E-Cham extracts reduced the parasitic burden in gerbils by 27.1% and 45.8%, respectively. Furthermore, the anthelmintic efficacy increased to 57.3% when both extracts were administered in combination. The results of the present study show an important combined nematicidal effect of the two plant extracts assessed against L3 in gerbils.
