The amplification of DNA from Chlamydia trachomatis by PCR with degenerated primers yielded a 345-bp fragment of the putative RNase P RNA gene. From the deduced DNA sequence of this gene in C. trachomatis, a modified primer pair was designed. The primer pair was subsequently used to obtain the corresponding gene products from Chlamydia pneumoniae and Chlamydia psittaci. Sequence comparisons revealed similarities of 76.6% between C. trachomatis and C. pneumoniae, 79.5% between C. trachomatis and C. psittaci, and 84.7% between C. pneumoniae and C. psittaci. Furthermore, the three species were differentiated by fragment length polymorphism analysis after restriction enzyme cleavage of the PCR products. Sequence variations among 14 serotypes of C. trachomatis were confined to one purine base substitution in the putative RNase P RNA gene of lymphogranuloma venereum strains L1 to L3. Complete sequence similarity was found for nine strains of C. pneumoniae of different geographic origins. Taken together, our results indicate a possibility of the general application of this method in clinical bacteriology. Analysis of the secondary structures of the putative RNase P RNA genes from the different Chlamydia species suggested that a novel structural element in the domain of RNase P RNA is involved in base pairing with the 3'-terminal CCA motif of a tRNA precursor. This structure has not previously been found among RNase P RNAs of members of the division Bacteria.
