Species-specific recombinant DNA probes for Mycoplasma meleagridis.
Two recombinant DNA probes (pMM-2 and pMM-13) were isolated from a Mycoplasma meleagridis strain 17529 genomic library prepared in plasmid pUC8, and Escherichia coli strain JM83. In dot blot assays, 32P-labeled pMM-13 with a DNA insert of 3.5 kbp, hybridized with 18 isolates of M. meleagridis but not with 16 other known species of avian mycoplasmas. Except for weaker signals on hybridization with the M. meleagridis cultures, pMM-2 with an DNA insert of 0.85 kbp, showed a similar reaction pattern. The minimal concentration of M. meleagridis strain 17529 chromosomal DNA that pMM-13 and pMM-2 detected were 1 and 8 ng, respectively. Neither probe hybridized with chromosomal DNA of M. gallisepticum strain S6, M. synoviae strain WVU-1853, or M. iowae strain I-695 at concentration of 256 ng.
