We amplified by polymerase chain reaction (PCR) and sequenced using an automated laser fluorescent DNA sequencer (Pharmacia) the intergenic spacer region (ITS) between the 16S and 23S rRNAs of the four species of Rochalimaea which were recently renamed Bartonella sp. We obtained DNA fragments of 1211, 1262, 1258 and 1529 bp for the reference species of B. quintana, B. henselae, B. vinsonii and B. elizabethae, respectively. The ITS of the four species are longer than previously reported in prokaryotes and contained the genes encoding isoleucine-tRNA (tRNA(Ile)) and alanine-tRNA (tRNA(Ala)). The sequences of the tRNA(Ala) genes are identical for the four Bartonella species, but the tRNA(Ile) gene sequence of B. quintana presents one mutation in comparison with the other species.

D001473	Bartonella	A genus of gram-negative bacteria characteristically appearing in chains of several segmenting organisms. It occurs in man and arthropod vectors and is found only in the Andes region of South America. This genus is the etiologic agent of human bartonellosis. The genus Rochalimaea, once considered a separate genus, has recently been combined with the genus Bartonella as a result of high levels of relatedness in 16S rRNA sequence data and DNA hybridization data.
