Bacteremia with fever due to a novel subspecies of Bartonella
vinsonii was found in a cattle rancher. The subspecies shared major characteristics of the genus Bartonella in terms of
most biochemical features and cellular fatty acid profile, but it was distinguishable from other subspecies of B. vinsonii by
good growth on heart infusion agar supplemented with X factor and by
its pattern of enzymatic hydrolysis of peptide substrates. DNA
relatedness studies verified that the isolate belonged to the genus
Bartonella and that it was genotypically related to
B. vinsonii. The highest level of relatedness was observed
with recently characterized strains from naturally infected mice that
were coinfected with Borrelia burgdorferi and Babesia
microti. We propose the name Bartonella vinsonii
subsp. arupensis subsp. nov. as the new subspecies to
accommodate these human and murine isolates.
