Serological and molecular surveys were conducted to determine the
occurrence of Bartonella henselae in domestic cats in Central Italy.
Samples from 234 pet cats were tested for B. henselae antibodies by
indirect immunofluorescence with 78 (33.3%) positive. A PCR assay
specific for the Bartonella 16S rRNA gene was carried out on DNA samples
extracted from blood of the 234 cats; 26 (11.1%) of the seropositive
cats were positive. Two PCR protocols, which discriminate genotypes I
and II of B. henselae, were performed on all DNA samples. Sixteen (6.8%)
cats were infected by genotype I, 6 (2.5%) by genotype II, and two males
(0.8%) by both genotypes. Two female (0.8%) cats which were Bartonella
sp. PCR positive, gave negative results with the types I and II PCR.
This protocol facilitates the direct and rapid detection of Bartonella
DNA in feline blood samples, and differentiates B. henselae genotypes.
