Bartonella infection causes overt clinical disease in naturally infected cats, in spite of a high prevalence of bacteremia and seropositivity in areas of the United States with warm temperatures and high humidity.
Bartonella in humans is between 3.6% to 15%; with the latter value occurring in a survey of veterinary professionals.

 Bartonella and Ticks Alert
Bartonella may not present in its usual form when additional infections, such as Lyme or Babesia are present.
In addition, typical Bartonella lesions are not always seen in patients, therefore, a diagnosis of "fever of unknown origin" should alert a physician to consider Bartonella.
It is estimated that approximately 2/3 of the patients with Bartonella have a fever.

 Bartonella - Wikipedia, the free encyclopedia
Bartonella is a Gram-negative genus of bacterium, some of which are extra-cellular, opportunistic human pathogens.
Every 5 days, a part of the Bartonella in the endothelial cells are released in the blood stream where they infect erythrocytes.
At this point, the Bartonella has simply to wait until it is taken with the erythrocytes by a blood-sucking arthropod.

 HealthGene - Bartonella spp.
At least four species are known to be human pathogens: Bartonella bacilliformis, the agent of Carrion’s disease; Bartonella quintana, the agent of trench fever and an agent of bacillary angiomatosis; B. henselae, the agent of cat scratch disease (CSD) and an agent of bacillary angiomatosis; and Bartonella elizabethae, which can cause endocarditis.
Bartonella vinsonii has been reported recently to be the cause of human endocarditis.
The prevalence of this bacterial infection, as determined by culture of cat blood, ranges from 4 to 70% according to the study and the type of cat population studied: pet, impounded, or former stray cats.

 HIV and Bartonella: Bacillary Angiomatosis and Peliosis
BA occurs most frequently in the later stages of HIV infection; in one study of 42 patients, the median CD4+ cell count was 21 per cubic millimeter (range: 1-228) at the time of diagnosis of BA.(48) In this case-control study, patients with BA infection presented with fever (9%), lymphadenopathy (21%), and/or abdominal symptoms (24%).
Additionally, Bartonella bacteremia occurs in the apparent absence of localized tissue infection.(21,23,75) Of two HIV-infected patients,(21) one was later found to have hepatic BP by retrospective analysis of a percutaneous liver biopsy with Warthin-Starry staining.(67) The majority of bacteremic patients had fever, chills, and weight loss that resolved after antibiotic therapy.
Detection of Bartonella DNA in tissue specimens has been used to diagnose osseous(26) and cutaneous BA(2,18,26,42) and BP of the spleen(2,18) and liver.(42,82) This PCR technique is not commercially available but has important applications in several settings.

 Bartonella spp. DNA associated with biting flies from California Emerging Infectious Diseases - Find Articles   (Site not responding. Last check: 2007-11-04)
Bartonella DNA was investigated in 104 horn flies (Haematobia spp.), 60 stable flies (Stomoxys spp.), 11 deer flies (Chrysops spp.), and 11 horse flies (Tabanus spp.) collected on cattle in California.
In California, Bartonella DNA was detected in approximately 19% of 151 questing adult I. pacificus ticks (8), but the direct role of ticks in Bartonella transmission among ruminants has never been established.
The amount of reagents for the deer and horse flies were doubled, and the flies were incubated in a waterbath overnight at 55[degrees]C. Bartonella DNA was detected by polymerase chain reaction (PCR) using primers for the citrate synthase (gltA) gene, as previously published (9).

Once Bartonella establishes chronic intracellular infection, its replication rate slows, antibody titers decline, and the pathogen is hard to isolate from the blood because of the low bacteremia.
A high serum titer (>1:512) against Bartonella combined with echocardiographic lesions associated with endocarditis, especially of the aortic valve, are highly suggestive of infectious endocarditis caused by B.

Isolates identified as Bartonella species were obtained from 21 of the 70 blood cultures.
A high prevalence of Bartonella infection in small mammals also has been described in other countries such as the United States (7) and Sweden (3), where 42.2% and 16.5% of the collected rodents were infected with Bartonella spp., respectively.

 Bartonella
Classically, cats transmit the organism when they are parasitized by fleas, scratch themselves, and get infected flea dirt (digested host’s blood excreted by fleas) in their claws, and scratch a person (or another cat) with their dirty claws.
Infection with Bartonella henselae in the immunocompetent person leads to “cat scratch disease.” The innoculation site (a bite or scratch) develops a small red bump (a “papule.”) About 2-3 weeks following contact with the infected cat, the lymph node in the area of the contact will swell and become painful and a fever develops.
It has been suggested that Bartonella infection may be a the root of numerous chronic inflammatory conditions of the cat.
