A one-step reverse transcriptase PCR (RT-PCR) method for detection of Borre
lia burgdorferi mRNA in infected C3H mice is described. This simple procedu
re, less prone to nucleic acid cross-contamination than the standard method
, was found to be 10-fold more sensitive than a classical two-step RT-PCR a
ssay. By using onestep RT-PCR, flagellin mRNAs were detected in synovial an
d heart tissues from all seven infected mice tested.
