Species of the genus Rochalimaea, recently renamed Bartonella, are of a
growing medical interest. Bartonella quintana was reported as the cause of
trench fever, endocarditis, and bacillary angiomatosis. B. henselae has
been implicated in symptoms and infections of human immunodeficiency
virus-infected patients, such as fever, endocarditis, and bacillary
angiomatosis, and is involved in the etiology of cat scratch disease. Such
a wide spectrum of infections makes it necessary to obtain an intraspecies
identification tool in order to perform epidemiological studies. B.
vinsonii, B. elizabethae, seven isolates of B. quintana, and four isolates
of B. henselae were studied by pulsed- field gel electrophoresis (PFGE)
after restriction with the infrequently cutting endonucleases NotI, EagI,
and SmaI. Specific profiles were obtained for each of the four Bartonella
species. Comparison of genomic fingerprints of isolates of the same species
showed polymorphism in DNA restriction patterns, and a specific profile was
obtained for each isolate. A phylogenetic analysis of the B. quintana
isolates was obtained by using the Dice coefficient, UPGMA (unweighted
pair-group method of arithmetic averages), and Package Philip programming.
Amplification by PCR and subsequent sequencing using an automated laser
fluorescent DNA sequencer (Pharmacia) was performed on the intergenic
spacer region (ITS) between the 16 and 23S rRNA genes. It was found that
each B. henselae isolate had a specific sequence, while the B. quintana
isolates fell into only two groups. When endonuclease restriction analysis
of the ITS PCR product was done, three enzymes, TaqI, HindIII, and HaeIII,
allowed species identification of Bartonella spp.(ABSTRACT TRUNCATED AT 250
