A virulent Newcastle disease virus strain was isolated from diseased chickens in Shanghai, China. The isolated strain was initially characterized as highly virulent because of a short mean death time in embryonated chicken eggs and specific-pathogen-free chickens and was typed as neurotropic by intracloacal inoculation of chickens. The isolated strain had a(More)
The aims of this research were to construct prokaryotic expression vector containing the gene of porcine urate oxidase (pUOX), optimize the conditions of the expression of pUOX in recombinant Escherichia coli BL21(DE3), and analyze the in vitro activity and the enzymological properties of pUOX. The pUOX gene was amplified by RT-PCR from the extracted total(More)
