| analysis of multi-strain bartonella pathogens in natural host population--do they behave as species or minor genetic variants? | modern advances in genetic analysis have made it feasible to ascertain the variant type of a pathogen infecting a host. classification of pathogen variants is commonly performed by clustering analysis of the observed genetic divergence among the variants. a natural question arises whether the genetically distinct variants are epidemiologically distinct. a broader question is whether the different variants constitute separate microbial species or represent minor variations of the same species. th ... | 2010 | 21352787 |

| three cases of pr3-anca positive subacute endocarditis caused by attenuated bacteria (propionibacterium, gemella, and bartonella) complicated with kidney injury. | subacute bacterial endocarditis (sbe) associated with antiproteinase-3 antineutrophil cytoplasmic antibodies (pr3-anca) has previously been reported in 10 cases of streptococcus viridans and in 1 case of escherichia faecalis infection. most of these patients had hypocomplementemia and were positive for several autoantibodies. the infections in most of these patients showed good responses to antibiotic treatment. we report three patients with anca-positive sbe, which was induced by attenuated slo ... | 2011 | 21400245 |
| bartonella henselae endocarditis of percutaneously implanted pulmonary valve: a case report. | percutaneous pulmonary valve implantation (ppvi) has revolutionized the management of right ventricular outflow tract dysfunction after repaired congenital heart disease. the technology is considered to be safe, with a relatively low complication rate. infection is one of the described complications of ppvi, and to date five cases of culture-positive infective endocarditis of percutaneously implanted pulmonary valve have been reported worldwide. herein is reported the first ever case of culture- ... | 2011 | 21404904 |
| 18f-fluoro-2-deoxyglucose positron emission tomography-negative endocarditis lenta caused by bartonella henselae. | it has been suggested that 18f-fluorodeoxyglucose positron emission tomography (fdg-pet) might serve as a tool for the often difficult diagnosis of infective endocarditis. the case is described of a patient with a bartonella henselae endocarditis with a negative fdg-pet. this case report demonstrates that negative fdg-pet findings do not rule out the presence of endocarditis. | 2011 | 21404906 |

| seasonality of cat-scratch disease, france, 1999-2009. | cat-scratch disease is seasonal in the united states and japan; but no data are available from europe. to assess the seasonality of the disease in france, we analyzed lymph node biopsy specimens collected during 1999-2009. most (87.5%) cases occurred during september-april and peaked in december. | 2011 | 21470466 |
| multilocus sequence typing of bartonella henselae in the united kingdom indicates that only a few, uncommon sequence types are associated with zoonotic disease. | bartonella henselae is one of the most common zoonotic agents acquired from companion animals (cats) in industrialized countries. nonetheless, although the prevalence of infections in cats is high, the number of human cases reported is relatively low. one hypothesis for this discrepancy is that b. henselae strains vary in their zoonotic potential. to test this hypothesis, we employed structured sampling to explore the population structure of b. henselae in the united kingdom and to determine the ... | 2011 | 21471345 |
| bartonella quintana in head louse nits. | the body louse is the principal vector of bartonella quintana, the causative organism of trench fever, but b. quintana dna has also been detected in adult head lice. because there are no characteristics that distinguish the body louse from the head louse, we decided to test head louse nits collected from a homeless man for the presence of b. quintana dna. all of the sampled nits tested positive by real-time pcr, and intergenic spacer region (its) gene sequences shared 100% similarity to the corr ... | 2011 | 21477003 |

| brief communication: co-detection of bartonella quintana and yersinia pestis in an 11th-15th burial site in bondy, france. | historical and anthropological data suggest that skeletons excavated from an 11th to 15th century mass grave in bondy, france, may be those of victims of the great plague. using high-throughput real-time pcr investigation of the dental pulp collected from 14 teeth from five such skeletons, we detected bartonella quintana dna in three individuals and yersinia pestis dna in two individuals. dna from five other deadly pathogens was not found. suicide pcr genotyping confirmed y. pestis dna belonging ... | 2011 | 21541920 |
| adhesins of bartonella spp. | adhesion to host cells represents the first step in the infection process and one of the decisive features in the pathogenicity of bartonella spp. b. henselae and b. quintana are considered to be the most important human pathogenic species, responsible for cat scratch disease, bacillary angiomatosis, trench fever and other diseases. the ability to cause vasculoproliferative disorders and intraerythrocytic bacteraemia are unique features of the genus bartonella. consequently, the interaction with ... | 2011 | 21557057 |
| bartonella quintana endocarditis of the tricuspid and mitral valves. | bartonella quintana is a gram-negative microorganism that can lead to culture-negative infective endocarditis (ie) in immunocompromised patients. here, we present an exceptionally rare case of a 70-year-old male with bartonella quintana-associated ie primarily limited to the tricuspid valve that spread to the mitral valve after tricuspid valve replacement. this was then complicated by infective spondylodiscitis of the thoracic vertebrae, ultimately resulting in death due to cardiac arrest. | 2011 | 21557164 |
| prosthetic valve endocarditis caused by bartonella quintana in a patient during immunosuppressive therapies for collagen vascular diseases. | bartonella quintana, known to cause various clinical symptoms, is increasingly recognized as one important cause of culture-negative endocarditis. we report a case of infectious endocarditis with b. quintana on the prosthetic valve, accompanied by proteinase 3-antineutrophil cytoplasmic antibody-positive collagen vascular disease-like symptoms 1 year earlier. | 2011 | 21558050 |
