Bartonella henselae strains genetically differ among nations. The utility of Japanese-specific YH-01 strain was investigated in developing indirect fluorescence antibody assay (IFA) for IgM in comparison with conventional IFA employing Houston-1 strain by testing 100 Japanese patients suspected of cat scratch disease. The country-specific IFA greatly improved the accuracy of diagnosis.

Two children with congenital heart disease status-post surgical correction presented with prolonged constitutional symptoms, hepatosplenomegaly and pancytopenia. Concern for malignancy prompted bone marrow biopsies that were without evidence thereof. In case #1, echocardiography identified a multilobulated vegetation on the conduit valve. In case #2, transthoracic, transesophageal and intracardiac echocardiography were performed and were without evidence of cardiac vegetations, however pulmonic emboli raised concern for infective endocarditis...

An 11 year old, hispanic girl with a history of B-cell acute lymphoblastic leukemia was admitted to the hospital for symptoms compatible with Bartonella henselae infection. The first molecularly diagnosed case of disseminated Bartonella henselae infection was reported in an immunocompromised patient in Lima, Peru. The analysis was confirmed by Polymerase Chain Reaction and automated sequencing of a liver biopsy sample, even though the serologic tests were negative. In conclusion, Bartonella spp. infection should have a particular diagnostic consideration in immunocompromised patients with fever of unknown origin and further investigation regarding the patient's past exposures with cats should also be elicited...

In bacteria, the second committed step in the diaminopimelate/lysine anabolic pathways is catalyzed by the enzyme dihydrodipicolinate reductase (DapB). DapB catalyzes the reduction of dihydrodipicolinate to yield tetrahydrodipicolinate. Here, the cloning, expression, purification, crystallization and X-ray diffraction analysis of DapB from the human-pathogenic bacterium Bartonella henselae, the causative bacterium of cat-scratch disease, are reported. Protein crystals were grown in conditions consisting of 5%(w/v) PEG 4000, 200 mM sodium acetate, 100 mM sodium citrate tribasic pH 5...

Among culture-negative endocarditis in the United States, Bartonella species are the most common cause, with Bartonella henselae and Bartonella quintana comprising the majority of cases. Kidney manifestations, particularly glomerulonephritis, are common sequelae of infectious endocarditis, with nearly half of all Bartonella patients demonstrating renal involvement. Although a pauci-immune pattern is a frequent finding in infectious endocarditis-associated glomerulonephritis, it is rarely reported in Bartonella endocarditis...

Bartonella henselae is a gram-negative facultative intracellular bacterium and is the causative agent of cat-scratch disease. Our previous data have established that Bacteroides fragilis colonization is able to prevent B. henselae damages through the polysaccharide A (PSA) in an experimental murine model. In order to determine whether the PSA is essential for the protection against pathogenic effects of B. henselae in immunocompromised hosts, SCID mice were co-infected with B. fragilis wild type or its mutant B...

Identifying the pathogen responsible for culture-negative valve endocarditis often depends on molecular studies performed on surgical specimens. A patient with Ehlers-Danlos syndrome who had an aortic graft, a mechanical aortic valve, and a mitral anulloplasty ring presented with culture-negative prosthetic valve endocarditis and aortic graft infection. Research-based polymerase chain reaction (PCR)/electrospray ionization mass spectrometry on peripheral blood samples identified Bartonella henselae. Quantitative PCR targeting the16S-23S ribonucleic acid intergenic region and Western immunoblotting confirmed this result...

Bartonella henselae is a gram-negative zoonotic bacterium that causes infections in humans including endocarditis and bacillary angiomatosis. B. henselae has been shown to grow as large aggregates and form biofilms in vitro. The aggregative growth and the angiogenic host response requires the trimeric autotransporter adhesin BadA. We examined the transcriptome of the Houston-1 strain of B. henselae using RNA-seq revealing nine novel, highly-expressed intergenic transcripts (Bartonella regulatory transcript, Brt1-9)...

A 65-year-old Japanese man was admitted with a 4-month history of fatigue and exertional dyspnea. Transthoracic echocardiography revealed a vegetation on the aortic valve and severe aortic regurgitation. Accordingly, infective endocarditis and heart failure were diagnosed. Although a blood culture was negative on day 7 after admission, a prolonged blood culture with subculture was performed according to the patient's history of contact with cats. Consequently, Bartonella henselae was isolated. Bartonella species are fastidious bacteria that cause blood culture-negative infective endocarditis...

Osteomyelitis of the spine with associated spinal epidural abscess represents an uncommon entity in the pediatric population, requiring prompt evaluation and diagnosis to prevent neurological compromise. Cat scratch disease, caused by the pathogen Bartonella henselae, encompasses a wide spectrum of clinical presentations; however, an association with osteomyelitis and epidural abscess has been reported in only 4 other instances in the literature. The authors report a rare case of multifocal thoracic osteomyelitis with an epidural abscess in a patient with a biopsy-proven pathogen of cat scratch disease...

INTRODUCTION: Bartonella henselae infection is a worldwide zoonosis with the domestic cat as reservoir. Although people with occupational contact with these pets are risk population only few studies of prevalence in them have been reported. METHODS: A study of seroprevalence of B. henselae was performed to veterinaries and other persons with occupational contact with cats, residents from the Bío-Bío region of Chile. Serum IgG antibodies against B. henselae were determined by indirect immunofluorescence (IFI)...

Cat-scratch disease (CSD) is a zoonosis in children, result of infection by Bartonella henselae, a gram-negative bacillus. Infection is generally characterized by regional and self-limited lymphadenopathy after exposure to a scratch or bite from a cat. Rarely, B. henselae is cause of fever of unknown origin (FUO), with dissemination to various organs, most often involving the reticuloendothelial system (liver, spleen, bone marrow), mimicking an inflammatory rather than a lymphoproliferative disease. Whole-body Magnetic Resonance Imaging (WBMRI), in association with diffusion-weighted imaging (DWIBS), allows a comprehensive evaluation of pediatric patients, without the risks inherent to ionizing radiation...

Bartonellosis is caused by the genus Bartonella. Bartonella is widely distributed in the ruminants, cats, dogs, rodents and other mammals including humans. At least 13 species or subspecies of Bartonella are zoonotic, and each species appears to be highly adapted to one or a limited number of reservoir animals in which it is asymptomatic, while it can be transmitted to humans in which a variety of clinical manifestations can be caused. It was reported that Bartonella henselae infection rate among domestic cats was high in nature, making it one of the leading, important, and easily neglected zoonotic diseases...

Lyme borreliosis (LB) is certainly the most common infection transmitted through the bite of Ixodes in Northern Hemisphere. These ticks are also able to transmit other microorganisms such as the bacteria Anaplasma phagocytophilum (Ap) and Bartonella henselae (Bh), with the latter discovered fairly recently, leading to diferent clinical presentations often close to those of LB. The aim of this study was to evaluate the frequency of co-infection by either of these bacteria in patients with LB, particularly when a treatment with beta-lactam antibiotic was only partially effective...

Bartonellae are blood- and vector-borne Gram-negative bacteria, recognized as emerging pathogens. Whole-blood samples were collected from 58 free-ranging lions (Panthera leo) in South Africa and 17 cheetahs (Acinonyx jubatus) from Namibia. Blood samples were also collected from 11 cheetahs (more than once for some of them) at the San Diego Wildlife Safari Park. Bacteria were isolated from the blood of three (5%) lions, one (6%) Namibian cheetah and eight (73%) cheetahs from California. The lion Bartonella isolates were identified as B...

Severe anemia and cholestatic hepatitis are associated with bartonella infections. A putative vertical Bartonella henselae infection was defined on the basis of ultrastructural and molecular analyses in a three-year-old child with anemia, jaundice and hepatosplenomegaly since birth. Physicians should consider bartonellosis in patients with anemia and hepatitis of unknown origin.
