TLDR
It is suggested that dogs could be a reservoir of this strain of B. rochalimae, in contrast to cats and guinea pigs, that was first isolated from the blood of a human who traveled to Peru and was exposed to multiple insect bites.Abstract:
Bartonella rochalimae was first isolated from the blood of a human who traveled to Peru and was exposed to multiple insect bites. Foxes and dogs are likely natural reservoirs for this bacterium. We report the results of experimental inoculation of two dogs, five cats and six guinea pigs with the only human isolate of this new Bartonella species. Both dogs became bacteremic for 5-7 weeks, with a peak of 10 3 -10 4 colony forming units (CFU)/mL blood. Three cats had low bacteremia levels (< 200 CFU/mL) of 6-8 weeks' duration. One cat that remained seronegative had two bacterial colonies isolated at a single culture time point. A fifth cat never became bacteremic, but seroconverted. None of the guinea pigs became bacteremic, but five seroconverted. These results suggest that dogs could be a reservoir of this strain of B. rochalimae, in contrast to cats and guinea pigs.

Laboratory mouse models for bartonella bacterial infection : bacteremia, host specificity, and pathology
TL;DR: This review discusses the history and present situation of bartonellae infections in rodents, interactions with eukaryotic host cells, and the development of host-bacteria model systems at the generative level.

Prevalence and diversity of small rodent-associated Bartonella species in Shangdang Basin, China
TL;DR: Overall, high occurrence and genetic diversity of Bartonella were observed among small rodents in the Shangdang Basin; this information could potentially help the prevention and control of rodent-Bartonella species in this area.

Characterization of Candidatus Bartonella ancashi: A Novel Human Pathogen Associated with Carrins Disease
TL;DR: Bacilliformis causes a biphasic illness, called Carrins disease, which is characterized by an acute phase, Oroya fever, and a chronic phase, verruga peruana, and is only seen in the Andes Mountain range of Peru, Ecuador, and Colombia.

TL;DR: P phenotypic and genotypic characterization of the isolate indicated that this organism, which can induce endocarditis in dogs, is a novel Bartonella subspecies containing an insertion sequence unique among currently recognized Bart onella species.

TL;DR: A patient who had fever and splenomegaly after traveling to Peru and also had bacteremia from an organism that resembled Bartonella bacilliformis was described, which revealed that this fastidious bacterium represented a previously uncultured and unnamed bartonella species.

TL;DR: These studies indicate that B. henselae exists in an almost perfect host-parasite relationship with its feline host, but that most cats can ultimately rid themselves of the infection.

TL;DR: Serologic surveys in Egypt have documented human and animal exposure to vector-borne bacterial pathogens, but the presence and distribution of these agents in arthropods has not been determined and fleas were collected from mammals trapped in 17 cities throughout Egypt.
