Bartonella henselae causes cat-scratch disease and presents systemic infection and with possible skin lesions. Lymphadenitis develops 2-3 weeks after exposure and can persist for several weeks. Bartonella quintana causes trench fever which is a recurrent fever that causes 3-5 febrile episodes.Bartonella, a causative agent of blood culture-negative endocarditis (BCNE) that usually requires valve surgery, was first attributed to endocarditis over 20 years ago (1-4).We report 2 cases of Bartonella prosthetic valve endocarditis that were successfully treated with antimicrobial drugs alone.. Case 1 involved a 62-year-old man admitted to the hospital in 2011 with left-flank pain and ...Bartonellae are considered to be emerging opportunistic pathogens. The bacteria are transmitted by blood-sucking arthropods, and their hosts are a wide range of mammals including humans. After a protective barrier breach in mammals, Bartonella colonizes endothelial cells (ECs), enters the bloodstream, and infects erythrocytes. Current …The common anti- Bartonella antibiotics, including AZI, DOX, GEN, and RIF, were used at their Cmax as controls. Compared to the drug-free control, as shown in Figure 2 A and Table 2, some of the antibiotics such as AZI and DOX showed poor activity in killing stationary phase B. henselae, partly due to their low Cmax.

Kittens are also more likely to scratch and bite while they play ...Bartonella spp. comprise a genus of Gram-negative alphaproteobacteria that are slow growing, fastidious, and facultative intracellular pathogens with zoonotic potential. Immunofluorescent antibody assays (IFAs), Western blot (WB), and enzyme-linked immunosorbent assays (ELISAs), the frequently used modalities for the serological diagnosis of canine and human Bartonelloses, generate numerous ...Bartonella species are fastidious, intracellular, gram-negative organisms that reside within erythrocytes. Due to this unique predilection, Bartonella is known to inhabit two specific sites: the gut of bloodsucking arthropods and bloodstreams of mammalian hosts [1].Cats have been identified as hosts when they become infected with B. henselae following the bite of infected fleas.Bartonellae are considered to be emerging opportunistic pathogens. The bacteria are transmitted by blood-sucking arthropods, and their hosts are a wide range of mammals including humans.

Etiology. The etiology of this disease process is currently unknown. 4 Multiple etiologies may exist that, either alone or combined, create the inflammation.4 Possible causative agents include an inflammatory response to plaque, viruses (particularly upper respiratory), Bartonella henselae infection, or altered immune status (feline immunodeficiency or leukemia viruses, FIV or FeLV). 1,5-8 ...Cat scratch disease is the most common zoonotic infection caused by Bartonella bacteria.

Almost 20 different species of Bartonella have been isolated thus far among in which Bartonella henselae, Bartonella quintana, and Bartonella bacilliformis are frequently associated with infections in humans. Bartonella henselae (B. henselae) is considered a rare cause of granulomatous hepatitis. Due to the fastidious growth characteristics of the bacteria, the limited sensitivity of histopathological stains, and the non-specific histological findings on liver biopsy, the diagnosis of hepatic bartonellosis can be difficult to establish. Furthermore, the optimal treatment of established hepatic ...
