    摘要: The invention provides a method for producing a continuous cell line capable of supporting the growth of a Marek's disease virus strain comprising infecting or transfecting a cell with a vector comprising a nucleic acid or fragment thereof of a Marek's disease virus strain and culturing said infected or transfected cell or progeny thereof under conditions suitable for the expression of said nucleic acid and propagation of said cell or progeny thereof. Preferably said nucleic acid or fragment thereof comprises a Marek's disease virus glycoprotein gE gene or functional fragment thereof. The invention further provides a method to generate and/or isolate and/or maintain a hypervirulent and/or very virulent, and/or very virulent plus, and/or virulent and/or avirulent Marek's disease virus strain comprising infecting a cell according to the invention with a hypervirulent, and/or very virulent, and/or very virulent plus, and/or virulent and/or avirulent Marek's disease virus strain and culturing said cell under conditions suitable for the propagation of said cell and the generation, maintenance and isolation of said hypervirulent, and/or very virulent, and/or very virulent plus, and/or virulent and/or avirulent Marek's disease virus strain. The invention further provides a method to prepare a vaccine capable of inducing protection against disease, preferably a Marek's disease virus associated disease in an avian comprising culturing a continuous cell according to the invention and harvesting cell culture components therefrom.
