Construction and use of derivatives of transposon Tn4001 that function in Mycoplasma pulmonis and Mycoplasma arthritidis

Academic Article


  • Previous attempts to introduce transposon Tn4001 into Mycoplasma pulmonis and Mycoplasma arthritidis have not been successful, possibly due to functional failure of the transposon's gentamicin resistance determinant. Tn4001C and Tn4OO1T were constructed, respectively, by insertion of a chloramphenicol acetyltransferase gene and the tetM tetracycline resistance determinant into Tn4001. Both Tn4001C and Tn4OO1T transposed in M. pulmonis, and Tn4OO1T transposed in M. arthritidis. The incorporation of a Tn4OO1T derivative that contained lacZ into either Mycoplasma species resulted in transformants with readily detectable LacZ activity. Tn4OO1T may be of general utility for use as a mycoplasma cloning vehicle because tetM functions in all species of Mycoplasma examined thus far.
