In rainbow trout (Oncorhynchus mykiss), following chronic (42 day) exposure to both 384 microg Ni l(-1) and 2034 microg Ni l(-1), Ni accumulation was greatest in the gill, kidney and plasma, with the plasma as the main sink for Ni. Indeed, trapped plasma analysis revealed that extensive loading of Ni in the plasma accounted for substantial percentages of(More)
The antimicrosporidial activity of albendazole was tested on Nosema bombycis in vitro in Spodoptera frugiperda cells and in vivo in Heliocoverpa zea larvae and pupae. Significant reductions in the percentage of infected S. frugiperda cells were obtained using a concentration of 5.3 micrograms/ml albendazole in tissue culture medium but recrudescence(More)
In moderately hard Lake Ontario water (approximately 140 mg L(-1) as CaCO3) waterborne Ni (9.7-10.7 mg Ni L(-1)) is acutely toxic to adult rainbow trout (Oncorhynchus mykiss) exclusively via branchial mechanisms. Ventilation in resting trout (evaluated using a ventilatory masking technique) was adversely affected, as ventilation rate (VR), ventilation(More)
