Amplification of a species-specific DNA fragment of Mycobacterium tuberculosis and its possible use in diagnosis

Abstract excerpt

In recent work, a species-specific Mycobacterium tuberculosis DNA fragment was cloned and sequenced. On the basis of its nucleotide sequence, two oligonucleotides were synthesized and used as primers for polymerase chain reaction (PCR) amplification. A 396-bp fragment was specifically amplified from the M. tuberculosis genome. No amplification was observed from any of 10 different mycobacterial strains, included...
