The present study was aimed to evaluate anthelmintic activity of aqueous and methanolic extract of Trapa natans L.var. bispinosa Roxb fruit peels and root. The plant commonly known as “Water Chestnut” in India and is an annual aquatic floating herb occurring throughout the Indian subcontinent and used traditionally for several medicinal purposes. The effect of this plant was evaluated for anthe...

The toxicity of Cu, Mn, Mo, Ni, V, As, Pb, Cr, Hg and Sn on the behaviour and survival of benthic worms Tubifex tubifex was studied. All tested metals were dissolved and determined in tap water under standardized conditions. The adverse effects of the metals were evaluated as acute toxicological effects upon exposure expressed as LC50 value with 95% confidence interval. On the basis of the LC50...

Introduction and spread of the parasite Myxobolus cerebralis, the causative agent of whirling disease, has contributed to the collapse of wild trout populations throughout the intermountain west. Of concern is the risk the disease may have on conservation and recovery of native cutthroat trout. We employed a Bayesian belief network to assess probability of whirling disease in Colorado River and...

We provide the first documented case of whirling disease (WD) impacts to wild, self-sustaining rainbow trout (RNTR, Oncorynchus mykiss) populations in Canada. Myxobolus cerebralis (Mc), causative agent WD, was confirmed Alberta 2016. However, evidence local fish unknown. Using a weight-of-evidence approach, we examined multiple parasite life cycle stages Crowsnest River, Alberta. Percentage inf...

IIlite clay particles with adsorbed 137Cs were added as a submillimeter layer to the surface of stir-clay sediments contained in rectangular Plexiglas ceils stored in a temperature-regulated aquarium, in order to tmee the effect of the ollgochaete, Tubifex tubifex, and the amphipod, Pontoporeia hoyi, on mass redistribution near the sedimentwater interface. A well-collimated NaI gamma detector s...

This study was conducted to evaluate the in vitro polyphenol content, antioxidant, cytotoxic, antibacterial, anthelmintic properties, and in vivo antinociceptive activity of the ethanol extract of Cissus adnata leaves (EECA) in different experimental models. Polyphenol contents were investigated using spectrophotometric techniques. Antioxidant activity was determined by 1,1-diphenyl-2-picrylhyd...
