To determine the prevalence of bacteremia caused by Bartonella henselae in
domestic cats in the region of Freiburg, Germany, we investigated culture
of blood from 100 cats from 89 different households over a 12- month
period. B. henselae could be isolated from 13% (13 of 100) of these cats.
In eight households with two cats each and in one household with three
cats, B. henselae bacteremia was found either in all of the animals or in
none of the animals. Positive cultures were more likely to be found for
female, young (24 months of age or younger) cats than for male or older
cats. Identification of the Bartonella isolates was made by colony
morphology, by Gram staining, biochemically by RapID ANA II or Rapid ID 32
A systems, and by whole-cell fatty acid analysis. Differentiation between
B. henselae and Bartonella quintana was only possible by 16S rRNA
sequencing, enterobacterial repetitive intergenic consensus (ERIC)-PCR and
sodium dodecyl sulfate-polyacrylamide gel electrophoresis. Genomic
fingerprinting of the B. henselae isolates by ERIC-PCR yielded two
different patterns based on three distinct bands.
