Bartonella henselae is a gram-negative bacillus implicated in cat-scratch disease. Cat-scratch disease is usually self-limiting and results in local lymphadenopathy. In rare circumstances, patients may develop endocarditis, neuroretinitis, or osteomyelitis. Osteomyelitis of the cervical spine is exceedingly rare, especially in the pediatric population, and to date there have been only 4 previously reported cases of cervical spine osteomyelitis caused by B. henselae, all of which were treated surgically. In this article, the authors report the case of a 7-year-old boy who presented with neck swelling and was found to have a C2-4 paravertebral B...

Bartonella spp. are emerging pathogens that are reported as the cause of blood culture-negative endocarditis ( BCNE). However, echocardiographic features and assessment of this endocarditis remains unclear. Four patients with B. henselae endocarditis were identified. All patients had underlying cardiac conditions: rheumatic heart disease in three, congenital heart disease in one. Evidence of vegetations was found on the aortic valve in all patients with large, highly mobile vegetations and severely destroyed valves demonstrated by the transthoracic echocardiogram leading to severe aortic regurgitation and heart failure...

We describe a patient with history of dextro-transposition of the great vessels, ventricular septal defect, and pulmonary valve replacement who presented with fatigue, prolonged fever, and leg edema. He was found to have kidney injury, pancytopenia, and liver congestion. Echocardiogram revealed thickened leaflets with prolapsing vegetation on the pulmonary valve. Given the negative blood cultures, high Bartonella henselae immunogobulin G titer (≥1:1024) and positive immunoglobulin M titer (≥1:20), he was diagnosed with Bartonella endocarditis complicated with glomerulonephritis...

BACKGROUND: Ticks are transmitting a wide range of bacterial pathogens that cause substantial morbidity and mortality in domestic animals. The full pathogen burden transmitted by tick vectors is incompletely studied in many geographical areas, and extensive studies are required to fully understand the diversity and distribution of pathogens transmitted by ticks. RESULTS: We sampled 824 ticks of 11 species collected in 19 counties in Romania. Ticks were collected mainly from dogs, but also from other domestic and wild animals, and were subjected to molecular screening for pathogens...

Infective endocarditis (IE) remains a severe and potentially fatal disease demanding sophisticated diagnostic strategies for detection of the causative microorganisms. The aim of the present study was to develop a broad-range 16S ribosomal RNA gene polymerase chain reaction in the routine diagnostic of IE for the early diagnosis of fatal disease. A broad-range PCR technique was selected and evaluated in terms of its efficiency in the diagnosis of endocarditis using 19 heart valves from patients undergoing cardiovascular surgeries at the Habib Bourguiba Hospital of Sfax, Tunisia, on the grounds of suspected IE...

RATIONALE: Fever of unknown origin (FUO) can be determined by different conditions among which infectious diseases represent the main cause. PATIENT CONCERNS: A young woman, with a history of aortic stenosis, was admitted to our unit for a month of intermittent fever associated with a new diastolic heart murmur and splenomegaly. Laboratory tests were negative for infectious screening. The total body computed tomography (CT) scan excluded abscesses, occulted neoplasia, or lymphadenopathy...

We read with great interest the Clinicopathologic Conference by Garg et al. published recently in Arthritis Care & Research about a patient with Bartonella-related endocarditis (1). However, we regret that the 'petechial pruritic rash' on the lower extremities and the presence of elevated rheumatoid factor were initially neglected in a context of glomerulonephritis. Indeed the rash was poorly described. This article is protected by copyright. All rights reserved.

Bartonella bovis is a small Gram-negative bacterium recognized as an etiological agent for bacteremia and endocarditis in cattle. As few reports are available on the taxonomic position of B. bovis and its mechanism of virulence, this study aims to resolve the phylogeny of B. bovis and investigate putative virulence genes based on whole genome sequence analysis. Genome-wide comparisons based on single nucleotide polymorphisms (SNP) and orthologous genes were performed in this study for phylogenetic inference of 27 Bartonella species...

Infective Endocarditis (IE) has high morbidity and mortality. To date, in addition to classic Gram-positive pathogens were isolated exigent Gram negative bacteria responsible of endocarditis as A. baumannii, A. lwoffii, C. burnetii, Bartonella, Chlamydia and Legionella. We report our experience about the isolation of Salmonella enterica phagetype 35 (PT35) from blood heart cavity of a 74-year-old woman after having consumed a portion of baked pasta bought in a rotisserie. Cardiovascular infections due to Salmonella enterica are infrequently reported, so their clinical features, prognosis, and optimal treatment are not completely known...

Infective endocarditis due to Bartonella bacilliformis is rare. A 64-year-old woman, without previous heart disease, presented with 6 weeks of fever, myalgias, and arthralgias. A systolic murmur was heard on the tricuspid area upon examination, and an echocardiogram showed endocardial lesions in the right atrium. Bartonella bacilliformis was isolated in blood cultures, defining the diagnosis of infective endocarditis using Duke's criteria. Subsequently, the patient developed clinical and laboratory features compatible with antineutrophil cytoplasmic antibody-associated vasculitis...

We investigated the microorganisms causing blood culture-negative endocarditis (BCNE) in Morocco. We tested 19 patients with BCNE by serologic methods, molecular methods, or both and identified Bartonella quintana, Staphylococcus aureus, Streptococcus equi, and Streptococcus oralis in 4 patients. These results highlight the role of these zoonotic agents in BCNE in Morocco.

PURPOSE: We report the case of a 59-year-old man with chronic hepatitis B and C infection presenting with acute kidney injury and enterococcus faecalis-infective endocarditis (IE). An elevated proteinase-3 (PR3)-ANCA and pauci-immune glomerulonephritis (GN) on renal biopsy were discovered, corresponding to ANCA-mediated GN. We conducted a literature review to assess the role of ANCA in IE and treatment implications. METHODS: On systematic review of the literature, we found five previous cases whereby IE caused by streptococcus and bartonella species were related to ANCA vasculitis-associated GN...

Bartonella henselae the causative agent of cat scratch disease (CSD), is a gram-negative, coccobacillus, facultative intracellular bacterium CSD usually presents as a clinical form of benign local lymphadenopathy (LAP) but sometimes it may progress to severe life threatening complications. Despite the fact that CSD is known to be a common disease, which is one of the important causes of local LAPs in the world, there are few publications in our country. For the diagnosis, the clinician should suspect for CSD and has to ask to the patient whether there is a story of cat scratch or not...

Infective Endocarditis (IE) is a disease with high morbidity and mortality. Nowadays, in addition to classic pathogens were isolated exigent Gram negative bacteria as A. baumannii, A. lwoffii, C. burnetii, Bartonella, Chlamydia and Legionella. We present our experience of Legionella isolations in environmental sample (water and air) collected from the Cardiology units belonging to two hospitals in Messina (Italy). A total of 80 samples were carried out, 30 and 50, respectively in the first and in the second structure: 55 of water and 25 of aerosol...

Bartonella quintana endocarditis, a common cause of culture-negative endocarditis in adults, has rarely been reported in children. We describe 5 patients 7-16 years of age from Ethiopia with heart defects and endocarditis; 4 cases were caused by infection with B. quintana and 1 by Bartonella of undetermined species. All 5 patients were afebrile and oligosymptomatic, although 3 had heart failure. C-reactive protein was normal or slightly elevated, and erythrocyte sedimentation rate was high. The diagnosis was confirmed by echocardiographic demonstration of vegetations, the presence of high Bartonella IgG titers, and identification of B...

Although emerging nonviral pathogens remain relatively understudied in bat populations, there is an increasing focus on identifying bat-associated bartonellae around the world. Many novel Bartonella strains have been described from both bats and their arthropod ectoparasites, including Bartonella mayotimonensis , a zoonotic agent of human endocarditis. This cross-sectional study was designed to describe novel Bartonella strains isolated from bats sampled in Mexico and evaluate factors potentially associated with infection...

Infective endocarditis is life-threatening; identification of the underlying etiology informs optimized individual patient management. Changing epidemiology, advances in blood culture techniques, and new diagnostics guide the application of laboratory testing for diagnosis of endocarditis. Blood cultures remain the standard test for microbial diagnosis, with directed serological testing (i.e., Q fever serology, Bartonella serology) in culture-negative cases. Histopathology and molecular diagnostics (e.g., 16S rRNA gene PCR/sequencing, Tropheryma whipplei PCR) may be applied to resected valves to aid in diagnosis...
