Infective Endocarditis in a Dog and the Phylogenetic Relationship of the Associated Bartonella rochalimae Strain with Isolates from Dogs, Gray Foxes, and a Human

The first case of canine endocarditis caused by Bartonella rochalimae is reported. By PCR-restriction fragment length polymorphism, sequence, and phylogenetic analyses, Bartonella isolates from a dog with endocarditis, 22 gray foxes, and three dogs, described as B. clarridgeiae like, were confirmed to belong to the new species B. rochalimae, suggesting canids as the natural reservoir.
