It is now established that two species of Bartonella,
namely, Bartonella henselae and B. quintana,
cause bacillary angiomatosis in human immunodeficiency virus-infected
patients. In addition, B. henselae causes cat scratch
disease and B. quintana, B. henselae, and
B. elizabethae can cause bacteremia and endocarditis in
immunocompetent persons. We have developed a PCR-restriction fragment
length polymorphism-based assay for direct detection and identification
to species level of Bartonella in clinical specimens. This
is accomplished by PCR amplification of Bartonella DNA
using primers derived from conserved regions of the gene carrying the
16S ribosomal DNA, followed by restriction analysis using
DdeI and MseI restriction endonucleases. We
amplified a Bartonella genus-specific 296-bp fragment from 25 clinical samples obtained from 25 different individuals. Restriction analysis of amplicons showed that identical patterns were seen from
digestion of B. henselae and B. quintana
amplicons with DdeI, whereas a different unique pattern was
seen by using the same enzyme with B. vinsonii and B. elizabethae. With MseI digestion, B. henselae and B. vinsonii gave nearly identical
patterns while B. quintana and B. elizabethae
gave a different pattern. By combining the restriction analysis data
generated with MseI and DdeI, unique "signature" restriction patterns characteristic for each species were obtained. These patterns were useful in identifying the
Bartonella species associated with each tissue specimen.
