 AB    SETTING: The polymerase chain reaction (PCR) is a rapid and specific
       method used to amplify a certain DNA fragment. It is applicable to rapid
       diagnosis of mycobacterial infections. By use of species-specific
       primers, it is possible to identify mycobacteria by PCR. In this study,
       a newly constructed primer was tested for specificity for Mycobacterium
       intracellulare in the PCR. OBJECTIVE: M. intracellulare is one of the
       most frequently found bacteria in opportunistic infection in AIDS, and
       rapid identification of this species is important. The purpose of this
       study was to construct a primer specific to this species as a suitable
       tool for identification. DESIGN: PCR products of M. tuberculosis and M.
       intracellulare, obtained by using the primers YNP-1 and YNP-2, were
       sequenced and compared. They showed a difference in the base sequences.
       A sequence unique to M. intracellulare was used as the primer specific
       to this species. Various mycobacterial and non-mycobacterial DNAs were
       used as the primer specific to this species. Various mycobacterial and
       non-mycobacterial DNAs were used as the template to evaluate the
       specificity of the newly constructed primers, YNP-7 and YNP-8. Sputum
       samples were also examined by PCR using the primers. RESULTS: In total
       25 species of culture mycobacterial and non-mycobacterial strains and 76
       sputum samples were tested by PCR. Only M. intracellulare DNA was
       amplified with PCR using the primers YNP-7/8. CONCLUSION: The
       specificity of the newly constructed primers for M. intracellulare was
       confirmed.
