Mycoplasma gallisepticum strain differentiation by arbitrary primer PCR (RAPD) fingerprinting.
We demonstrate here that the arbitrary primer polymerase-chain-reaction-based DNA fingerprinting method (also termed random amplified polymorphic DNA or RAPD) can be used to distinguish among strains of the avian pathogen Mycoplasma gallisepticum. Ten base oligonucleotide primers were used individually to prime DNA synthesis from genomic DNAs. Strain-specific arrays of DNA fragments were generated, which allowed us to identify and group isolates. Isolates of M. synoviae, M. gallinarum and M. iners yielded arrays of DNA fragments that differed markedly from those generated from the M. gallisepticum isolates using the same arbitrary primers. These results show that the RAPD fingerprinting method distinguishes genetically different strains of M. gallisepticum and indicates that it should be valuable for monitoring transmission of this pathogen.
