Pyocin typing may be unstable under certain circumstances. In the early seventies, it was shown that the IncP-2 plasmids pMG1 and pMG2 interfered with the pyocin type of some Pseudomonas aeruginosa strains. Up to now, details of the influence of these plasmids on the pyocins are unknown. In this study, the effect of these plasmids on the R, F, and S pyocins, respectively, was examined. In distinct strains, S pyocin activity was detected in the presence of these plasmids, whereas R and F pyocin activities could not be observed. So the effect of the IncP-2 plasmids pMG1 and pMG2 may be limited to the R and/or F pyocins.
在某些情况下，绿脓菌素分型可能不稳定。在七十年代早期，研究表明IncP - 2质粒pMG1和pMG2会干扰一些铜绿假单胞菌菌株的绿脓菌素类型。到目前为止，这些质粒对绿脓菌素影响的具体细节尚不清楚。在本研究中，分别检测了这些质粒对R、F和S绿脓菌素的影响。在不同菌株中，在这些质粒存在的情况下检测到了S绿脓菌素活性，而未观察到R和F绿脓菌素活性。因此，IncP - 2质粒pMG1和pMG2的作用可能仅限于R和/或F绿脓菌素。
