    • 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.
    • 本发明提供了一种能够支持马立克氏病病毒株生长的连续细胞系的方法,其包括用包含马立克氏病病毒株的核酸或其片段的载体感染或转染细胞,并培养所述感染或转染 在适于表达所述核酸的条件和所述细胞或其后代的繁殖条件下的细胞或其后代。 优选地,所述核酸或其片段包含马立克氏病病毒糖蛋白gE基因或其功能片段。 本发明进一步提供了产生和/或分离和/或维持高毒力和/或非常有毒的和/或非常有毒的加和/或毒性和/或无毒的马立克氏病病毒株的方法,包括根据 发明具有高毒力和/或非常有毒的和/或非常有毒的加和/或毒性和/或无毒的马立克氏病病毒株,并且在适合于传播所述细胞的条件下培养所述细胞以及产生,维持和分离 的所述高毒力和/或非常有毒的,和/或非常有毒的加和/或毒性和/或无毒的马立克氏病病毒株。 本发明进一步提供一种制备能够诱导针对疾病的疫苗的疫苗的方法,优选禽类中的马立克氏病病毒相关疾病,包括培养根据本发明的连续细胞并从其中收获细胞培养成分。
