Chlamydophila felis: plasmid detection in Italian isolates.
Plasmids have been detected in the majority of strains in the genus Chlamydia and in many Chlamydophila species. Previous studies showed that FP Pring and FP Cello Chlamydophila felis strains have an extrachromosomial plasmid, whereas the FP Baker strain does not. Azuma et al. recently sequenced the entire genomic DNA sequence of the Japanese Cp. felis strain Fe/C-56 and described a 7,552 base pair circular plasmid. In the present study a highly conserved plasmid gene was detected in 11 Italian Cp. felis isolates, showing 100% nucleotide identity with the plasmid gene of Fe/C-56 Cp. felis strain.
