Abstract:
The present invention provides methods of detecting or distinguishing the DNA of an individual strain of Mycobacterium tuberculosis utilizing the polymerase chain reaction (PCR). Reproducible, unique patterns can be produced allowing the identification of unknown M. tuberculosis DNA by performing this reaction and comparing the pattern produced to the known reproducible, unique patterns. The invention further provides a kit useful to detect or distinguish the DNA of an individual strain of M. tuberculosis in a sample, comprising specific primers for use in PCR. The present invention also provides a method of determining the presence of a multidrug-resistant M. tuberculosis by detecting the presence of a specific arrangement of genomic DNA. Such detection can be done using PCR or a ligase chain reaction (LCR). The present invention provides nucleic acid sequences useful in detecting multidrug-resistant M.
