Abstract: | DNA amplification by the polymerase chain reaction (PCR) was examined to detect DNA of Mycoplasma hyopneumoniae, an etiological agent of porcine pneumonia. A pair of synthetic primers was selected that specify the amplification of a 520-basepair DNA fragment in a reiterative sequence of M. hyopneumoniae genome. The PCR product was detected by direct gel electrophoresis or by blot hybridization to a synthetic oligonucleotide probe. The specificity of PCR for M. hyopneumoniae was confirmed by lack of cross-reactivity to DNA from other porcine mycoplasmas. |
