| 摘要 |
<p>The present invention relates to a DNA molecule conferring on Mycobacterium tuberculosis an ability to enter mammalian cells and to survive within macrophages. The protein encoded by this gene fragment is useful in vaccines to prevent infection by Mycobacterium tuberculosis, while the antibodies raised against this protein can be employed in passively immunizing those already infected by the organism. Both these proteins and antibodies may be utilized in diagnostic assays to detect Mycobacterium tuberculosis in tissue or bodily fluids. The protein of the present invention can be associated with various other therapeutic materials, for administration to mammals, particularly humans, to achieve uptake of those materials by such cells.</p> |
