Polymerase chain reaction (PCR) amplification was performed using DNA purified from 15 mycobacterial type strains and from 21 specimens isolated from patients suspected to have non-tuberculous mycobacterial diseases. Using a primer set of MTB1-MTB2, 11 specimens out of 21 were Mycobacterium avium and 8 were M. intracellulare, which were verified by the Gen Probe Rapid Diagnostic System for the M. avium complex (MAC). One of the remaining 2 specimens which did not hybridize with the probe for the MAC was identified as M. kansasii and the other was not specifically identified by the conventional culture method. PCR amplification, using a primer set of TB1-TB3, was also performed for the specific identification of M. tuberculosis complex.

D008969 Molecular Sequence Data Descriptions of specific amino acid, carbohydrate, or nucleotide sequences which have appeared in the published literature and/or are deposited in and maintained by databanks such as GENBANK, European Molecular Biology Laboratory (EMBL), National Biomedical Research Foundation (NBRF), or other sequence repositories. Sequence Data, Molecular,Molecular Sequencing Data,Data, Molecular Sequence,Data, Molecular Sequencing,Sequencing Data, Molecular
D009841 Oligonucleotides Polymers made up of a few (2-20) nucleotides. In molecular genetics, they refer to a short sequence synthesized to match a region where a mutation is known to occur, and then used as a probe (OLIGONUCLEOTIDE PROBES). (Dorland, 28th ed) Oligonucleotide
D004269 DNA, Bacterial Deoxyribonucleic acid that makes up the genetic material of bacteria. Bacterial DNA

D013183 Sputum Material coughed up from the lungs and expectorated via the mouth. It contains MUCUS, cellular debris, and microorganisms. It may also contain blood or pus. Sputum, Induced,Induced Sputum,Induced Sputums,Sputums,Sputums, Induced
D015269 Mycobacterium avium Complex A complex that includes several strains of M. avium. M. intracellulare is not easily distinguished from M. avium and therefore is included in the complex. These organisms are most frequently found in pulmonary secretions from persons with a tuberculous-like mycobacteriosis. Strains of this complex have also been associated with childhood lymphadenitis and AIDS; M. avium alone causes tuberculosis in a variety of birds and other animals, including pigs.

D016133 Polymerase Chain Reaction In vitro method for producing large amounts of specific DNA or RNA fragments of defined length and sequence from small amounts of short oligonucleotide flanking sequences (primers). The essential steps include thermal denaturation of the double-stranded target molecules, annealing of the primers to their complementary sequences, and extension of the annealed primers by enzymatic synthesis with DNA polymerase. The reaction is efficient, specific, and extremely sensitive. Uses for the reaction include disease diagnosis, detection of difficult-to-isolate pathogens, mutation analysis, genetic testing, DNA sequencing, and analyzing evolutionary relationships.
