摘要: Polynucleotides associated with virulence in mycobacteria, and particularly a fragment of DNA isolated from M. bovis that contains a region encoding a putative sigma factor. Also provided are methods for a DNA sequence or sequences associated with virulence determinants in mycobacteria, and particularly in M. tuberculosis and M. bovis. The invention also provides corresponding polynucleotides associated with avirulence in mycobacteria. In addition, the invention provides a method for producing strains with altered virulence or other properties which can themselves be used to identify and manipulate individual genes.
摘要翻译: 与分枝杆菌中的毒力相关的多核苷酸,特别是分离自牛分枝杆菌的DNA片段,其含有编码推定的西格玛因子的区域。 还提供了在分枝杆菌,特别是结核分枝杆菌和牛分枝杆菌中的DNA序列或与毒力决定簇相关的序列的方法。 本发明还提供了与分枝杆菌中无毒性相关的相应多核苷酸。 此外,本发明提供了一种用于产生具有改变的毒力或其他性质的菌株的方法,其本身可用于鉴定和操纵个体基因。
