Cats have been shown to provide the only known reservoir of Bartonella
henselae, the causative agent of cat scratch disease. To determine the
prevalence of Bartonella bacteremia and antibodies in Dutch cats, blood
samples from 113 cats from shelters (sheltered cats), 50 pet cats, and 25
specific-pathogen-free (SPF) cats were analyzed. Culture and subsequent
PCR-restriction fragment length polymorphism (RFLP) analysis of the 16S-23S
rRNA intergenic region and 16S rRNA gene PCR- hybridization assays revealed
a prevalence of Bartonella bacteremia in 22% of the sheltered cats and
showed no bacteremia in the SPF cats. Three spacer RFLP types were found:
types A, B, and G, with type B being predominant over types A and G. An
important finding was the existence of mixtures of different Bartonella
species. Bartonella DNA was detected in 7 of 27 DNA extracts from fleas
combed from the sheltered cats (26%). Seropositivity was 50% for sheltered
cats and 56% for pet cats, as determined by a B. henselae enzyme-linked
immunoassay.
