Repetitive-element PCR (rep-PCR) with primers based on repetitive
extragenic palindromic (REP) and enterobacterial repetitive intergenic
consensus (ERIC) repeated DNA sequences was used for genomic finger-
printing of Bartonella species. This technique was applied by using either
extracted genomic DNA or preparations of whole bacterial cells directly.
PCR fingerprints with either the REP-based primers (REP-PCR) or primers
based on the ERIC repeat (ERIC-PCR) revealed species- specific band
patterns for the various Bartonella isolates. DNA fingerprints obtained
from rep-PCR of extracted genomic DNA or from preparations of whole cells
yielded comparable patterns. ERIC-PCR banding patterns were less complex
than those obtained by REP-PCR but allowed better discrimination between
strains within species. By combining results of REP-PCR and ERIC-PCR, five
different fingerprint profiles were identified among 17 isolates of
Bartonella henselae, but only one profile was identified among the five
isolates of Bartonella quintana. Other Bartonella species yielded distinct
rep-PCR fingerprints. rep-PCR is a useful technique for identification of
Bartonella organisms to the species level and offers the advantage of ease
of performance, with only small quantities of cells needed for the
whole-cell procedure. This technique also appears to be useful for
subtyping B. henselae isolates.
