| "candidatus bartonella thailandensis": a new genotype of bartonella identified from rodents. | bartonella species, intracellular parasite of erythrocytes and endothelial cells, are zoonotic pathogens of wild and domestic animals including rodents. many species of rodents are commensally infected with a few bartonella species in asia. however, there are only few reports on detection of bartonella in thailand. our objective was to detect the presence of bartonella species in rodents from thailand. among 247 rodents captured in five provinces from thailand we identified bartonella species us ... | 2009 | 19574002 |
| run-off replication of host-adaptability genes is associated with gene transfer agents in the genome of mouse-infecting bartonella grahamii. | the genus bartonella comprises facultative intracellular bacteria adapted to mammals, including previously recognized and emerging human pathogens. we report the 2,341,328 bp genome sequence of bartonella grahamii, one of the most prevalent bartonella species in wild rodents. comparative genomics revealed that rodent-associated bartonella species have higher copy numbers of genes for putative host-adaptability factors than the related human-specific pathogens. many of these gene clusters are loc ... | 2009 | 19578403 |
| detection of bartonella spp. in wild rodents in israel using hrm real-time pcr. | the prevalence of bartonella spp. in wild rodents was studied in 19 geographical locations in israel. one hundred and twelve rodents belonging to five species (mus musculus, rattus rattus, microtus socialis, acomys cahirinus and apodemus sylvaticus) were included in the survey. in addition, 156 ectoparasites were collected from the rodents. spleen sample from each rodent and the ectoparasites were examined for the presence of bartonella dna using high resolution melt (hrm) real-time pcr. the met ... | 2009 | 19595521 |
| infective endocarditis by bartonella quintana masquerading as antineutrophil cytoplasmic antibody-associated small vessel vasculitis. | the bartonella species have been recently recognized as important causative agents of culture-negative bacterial endocarditis. antineutrophil cytoplasmic antibodies (ancas) have been associated with the spectrum of idiopathic small vessel vasculitis. however, a variety of infections can result in a false-positive anca test, and especially subacute bacterial endocarditis (sbe) with the presence of ancas occasionally mimics the clinical manifestations of an anca-associated vasculitis such as skin ... | 2009 | 19602882 |
| the bacteriology of salivary gland infections. | the parotid gland is the salivary gland most commonly affected by inflammation. however, infection of the salivary glands can occur in any of the glands. the most common pathogens associated with acute bacterial infection are staphylococcus aureus and anaerobic bacteria. the predominant anaerobes include: anaerobic gram negative bacilli (eg, pigmented prevotella and porphyromonas); fusobacterium spp; and peptostreptococcus spp. in addition, streptococcus spp (including streptococcus pneumoniae) ... | 2009 | 19608044 |

| cat scratch disease: a diagnostic conundrum. | we report the case of a patient who presented to a clinic for evaluation of inguinal lymphadenopathy. histology of the lymph nodes revealed micoabscess formation suggesting infection with lymphogranuloma venereum (lgv) or bartonella henselae--the causative agent in cat scratch disease (csd). the patient recalled no preceding animal exposure. clinical and serological findings initially suggested early lgv but convalescent serology supported csd. this serves as an important reminder that b. hensel ... | 2009 | 19625597 |
| bartonella rattaustraliani sp. nov., bartonella queenslandensis sp. nov. and bartonella coopersplainsensis sp. nov., identified in australian rats. | a total of 11 bartonella isolates were recovered from the blood of melomys, uromys and rattus species in australia and were characterized using phenotypic and genotypic methods. comparison of 16s rrna gene, ftsz, glta and 16s-23s rrna internal transcribed spacer region sequences from the isolates indicated that they formed three sequence similarity groups that were distinct from one another and from the currently recognized bartonella species. phylogenetic analysis based on alignment of concaten ... | 2009 | 19628592 |
| diffusion-weighted magnetic resonance imaging in cervical lymphadenopathy: report of three cases of patients with bartonella henselae infection mimicking malignant disease. | diffusion-weighted mr imaging is a potential technique for differentiation between benign and malignant lymph nodes. however, lympadenopathy caused by bartonella henselae infection showes low adc values in diffusion weighted mri as typically seen in malignant disease. | 2009 | 19636985 |

| pestilence, persistence and pathogenicity: infection strategies of bartonella. | it has been nearly two decades since the discovery of bartonella as an agent of bacillary angiomatosis in aids patients and persistent bacteremia and 'nonculturable' endocarditis in homeless people. since that time, the number of bartonella species identified has increased from one to 24, and 10 of these bacteria are associated with human disease. although bartonella is the only genus that infects human erythrocytes and triggers pathological angiogenesis in the vascular bed, the group remains un ... | 2009 | 19659429 |
| the pathophysiology of the acute phase of human bartonellosis resembles aids. | human bartonellosis is a south american anthroponosis caused by bartonella bacilliformis. the disease has an acute phase characterized by invasion of red blood cells by parasites, and consequent severe anemia; and a chronic phase presenting with benign vascular tumors. during the acute phase, affected individuals are prone to developing opportunistic infections with a variety of organisms similar to the ones seen in aids. after antibiotic treatment is instituted, a subgroup of patients may devel ... | 2010 | 19665314 |

| molecular detection of bartonella henselae and bartonella koehlerae from aortic valves of boxer dogs with infective endocarditis. | cardiac aortic valves from five dogs that died from acquired infective endocarditis were retrospectively molecularly screened for bartonella infection. identification was carried out using pcr targeting four gene fragments (rpob, ribc, 16s rrna and glta), and the 16s-23s intergenic spacer (its). bartonella henselae dna was detected in aortic valve tissue from one boxer dog with moderate subaortic stenosis (sas). bartonella koehlerae dna was detected from the aortic valve of another boxer dog wit ... | 2010 | 19716241 |
| bartonellosis as cause of death after red blood cell unit transfusion. | the authors present the case of a young man with aplastic anemia who went into shock and died after several red blood cell unit transfusions. immunohematological studies did not show any abnormality and blood cultures from patients and blood bags were negative. the ultrastructural findings, allied with current scientific knowledge, permitted the diagnosis of bartonella sp. infection. in face of this diagnosis, two possibilities should be considered: the first one is that the patient was already ... | 2009 | 19728230 |
