Isolation and genetic characterization of a Bartonella strain closely related to Bartonella tribocorum and Bartonella elizabethae in Israeli commensal rats.

Ten Bartonella isolates were cultured from blood drawn from black rats (Rattus rattus) captured in the Tel Aviv area. Genetic characterization included amplification and sequencing of five gene fragments including the ribC, rpoB, 16S, groEL, and gltA and the 16S-23S intergenic spacer region. Sequence comparisons showed that all 10 isolates were identical in all genes studied comprising a total of 3,873 bp analyzed.
