BACKGROUND: The control of coccidiosis in poultry industryis dominated by prophylactic chemotherapy; however,drug resistance is a serious problem. Alternative control methodssuch as vaccination have been accepted as a practical method forcontrolling coccidiosis in chickens. Considering the immunologicalvariation of Eimeria strains, the efficacy of live coccidiosisvaccines may be compromised. OB...

High pH values have been found necessary for optimum activity of alkaline phosphatase in vitro. The pH values in the living cell structures, on the other hand, are near neutrality: cytoplasm 6.9, nucleus 7.6 (l-3). This definite difference between the pH required for optimum activity and the pH of the living cell indicates that alkaline phosphatase is not optimally active in viva. However, the ...

Objective: Peel of Amorphophallus is considered as waste. In this study we checked for the presence of cellulase enzyme in this waste and investigated its biochemical properties. Methods: Presence of cellulase activity was confirmed by Congo red plate diffusion assay The optimum temperature, pH, substrate concentration for both CMCase and FPase activity was also determined by DNS method. Effect...

Penicillium sp. FO-1611, a soil isolate, was found to produce a series of new anticoccidial compounds. Three active compounds, designated hynapenes A, B and C, were isolated from the fermentation broth of the producing strain by solvent extraction, silica gel column chromatography, gel filtration on Sephadex LH-20 and preparative HPLC. Hynapenes inhibited the growth of Eimeria tenella in an in ...

INTRODUCTION Ionophore antibiotics are widely used in veterinary medicine as anticoccidial drugs for poultry and as growth promoters for farm animals. The ionophores, despite their utility, possess a narrow range of safety; several species (horses in particular) appear highly susceptible to the toxic effects of these compounds, compared to other animal species. Thin layer chromatography method ...
