| bartonella seropositivity in children with henoch-schonlein purpura. | an association between henoch-schonlein purpura (hsp) and seropositivity for bartonella henselae (bh) has been described. the objective of this study was to see if such an association exists in northern alberta. | 2005 | 15807903 |
| [bartonella and bartonellosis--emerging and re-emerging infections: epidemiology, clinical course, diagnosis]. | information on the epidemiology, clinic and diagnostics of bartonellosis is updated. the importance of bartonellosis lies in the fact that its main risk group embraces patients with immunodeficiencies of different origin, the number of such patients constantly growing. the diagnostics of bartonellosis is insufficiently developed and the research on bartonella organisms, except for the trunch (volynia) fever causative agent, is insufficient in our country. | 2005 | 15773411 |
| [non infectious endocarditis: retrospective study (6 cases)]. | if there is cardiac valve vegetation and the blood cultures are negatives we need to look for slow growing bacteria, fungi, legionella pneumophilia, bartonella henselae and quintana, brucella melitensis and abortus, coxiella burneti, chlamydiae pneumoniae by serologic tests. the diagnosis of non- infectious endocarditis could be considered only if these results were negative. the main purpose of this study was to describe the clinical and echocardiographic signs of non-infectious endocarditis ca ... | 2005 | 15777581 |
| multifocal bone marrow involvement in cat-scratch disease. | we describe 2 children with prolonged fever of unknown origin and prominent skeletal pain who had multifocal bone disease caused by bartonella infection. initial radiologic studies, including plain films, radionuclide scintigraphy and computed tomography, yielded negative results. in both cases, magnetic resonance imaging revealed multiple enhancing bone marrow lesions consistent with clinical symptoms. microbiologic diagnoses were established serologically. | 2005 | 15876956 |
| autochthonous epidemic typhus associated with bartonella quintana bacteremia in a homeless person. | trench fever, a louse-borne disease caused by bartonella quintana, is reemerging in homeless persons. epidemic typhus is another life-threatening louse-borne disease caused by rickettsia prowazekii and known to occur in conditions of war, famine, refugee camps, cold weather, poverty, or lapses in public health. we report the first case of seroconversion to r. prowazekii in a homeless person of marseilles, france. this was associated with b. quintana bacteremia. although no outbreaks of typhus ha ... | 2005 | 15891141 |
| [diseases produced by bartonella]. | the genus bartonella is cause of a broad number of emerging and re-emerging infectious diseases. clinical manifestations depend on the implicated bartonella sp. and the immunity of the host. because there is not a universal therapy for this infection, treatment should be chosen individually. bartonella sp. is responsible of potentially serious clinical pictures (endocarditis, chronic bacteremia, bacillary angiomatosis, carrion's disease, etc.), so clinical suspicion, a quick diagnosis and an ear ... | 2005 | 15899181 |
| seroprevalence of antibodies against bartonella species and evaluation of risk factors and clinical signs associated with seropositivity in dogs. | to determine the seroprevalence of antibodies against bartonella spp in a population of sick dogs from northern california and identify potential risk factors and clinical signs associated with seropositivity. | 2005 | 15900951 |
| evidence of bartonella sp. in questing adult and nymphal ixodes ricinus ticks from france and co-infection with borrelia burgdorferi sensu lato and babesia sp. | ticks are known vectors for a wide range of pathogenic microorganisms. their role in the transmission of some others is so far only suspected. ticks can transmit multiple pathogens, however, little is known about the co-existence of these pathogens within questing ticks. we looked for the presence of dna from three micro-organisms, bartonella sp., borrelia burgdorferi sensu lato and babesia sp. which are known or suspected tick-borne pathogens, using a cohort of 92 questing ixodes ricinus ticks ... | 2005 | 15610725 |
| demonstration of intracellular microorganisms (rickettsia spp., chlamydia pneumoniae, bartonella spp.) in pathological human aortic valves by pcr. | rickettsiae, which causes vasculitis, has not been linked to atherosclerotic cardiovascular disease in contrast to chlamydia pneumoniae whose association with coronary artery disease and with sclerotic heart valves in patients undergoing aortic valve replacement is well established, even if causality is yet to unproven. in the search for any of these infectious agents, 84 pathological and 15 normal aortic heart valves of patients undergoing forensic autopsy were analysed by pcr and dna-sequencin ... | 2005 | 15603840 |
| a review of emerging flea-borne bacterial pathogens in new zealand. | recent studies have shown that rickettsia typhi, r. felis, bartonella henselae, and b. clarridgeiae occur in new zealand. to raise awareness of these emerging and re-emerging flea-borne bacterial pathogens among new zealand health workers, we review the clinical features, diagnosis, and treatment of infections, and the biology of the major flea vectors. | 2005 | 15682209 |

| a serological study of exposure to arthropod-borne pathogens in dogs from northeastern spain. | there is limited information regarding the prevalence of many vector borne pathogens in europe and especially in spanish dogs. we investigated 206 sick and 260 clinically healthy dogs from three different regions in northeastern spain for antibodies to rickettsia conorii (rc), ehrlichia canis (ec), anaplasma phagocytophilum (ap), bartonella henselae (bh), bartonella vinsonii subsp. berkhoffii (bvb), leishmania infantum (li) and borrelia burgdorferi (bb) and for antigen of dirofilaria immitis (di ... | 2006 | 16472522 |
| secondary unilateral glaucoma and neuroretinitis: atypical manifestation of cat-scratch disease. | 2006 | 16604397 | |
| bartonella quintana associated neuroretinitis. | we report an observational case of bartonella quintana-associated neuroretinitis. the patient had a positive igm ifa titer for bartonella quintana early in the disease. after treatment, the neuroretinitis and igm resolved. given the patient's history, symptoms, response to treatment, and igm course, we believe his neuroretinitis was secondary to bartonella quintana. | 2006 | 16449005 |
| effects of cow age and pregnancy on bartonella infection in a herd of dairy cattle. | bartonella spp. are small hemotropic bacteria infecting mammals. four bartonella species have been recently described in cattle and wild ruminants. to date, the biology and possible pathogenic role of bartonella species isolated from ruminants are poorly understood. therefore, a dairy herd of 448 cows and heifers was surveyed in order to establish the prevalence of bartonella bovis and b. chomelii infections, the level of bacteremia, and the relationship between bacteremia and age or pregnancy s ... | 2006 | 16390945 |
| bartonella quintana characteristics and clinical management. | bartonella quintana, a pathogen that is restricted to human hosts and louse vectors, was first characterized as the agent of trench fever. the disease was described in 1915 on the basis of natural and experimental infections in soldiers. it is now recognized as a reemerging pathogen among homeless populations in cities in the united states and europe and is responsible for a wide spectrum of conditions, including chronic bacteremia, endocarditis, and bacillary angiomatosis. diagnosis is based on ... | 2006 | 16494745 |
| first isolation of bartonella alsatica from a valve of a patient with endocarditis. | we report the first documented case of endocarditis in a man infected with bartonella alsatica, which causes bacteremia in healthy wild rabbits. b. alsatica was identified by serology and culture and by pcr of an aortic valve specimen. b. alsatica should be added to the list of zoonotic agents of blood culture-negative endocarditis. | 2006 | 16390990 |
| localized bacillary angiomatosis in the oral cavity: observations about a neoplasm with atypical behavior. description of a case and review of the literature. | bacillary angiomatosis is a rather frequent infectious pathology appearing mainly in the skin but can also affect the liver, spleen, heart, bones, lungs, muscles, central nervous system and other organs. the localization of the lesion in the oral cavity is rather rare, as it is evident in the literature. bacillary angiomatosis can be clinically similar to the kaposi's sarcoma and histologically confused with angiosarcoma, epitheloid hemangioma and pyogenic granuloma. a case of bacillary angiomat ... | 2006 | 16495874 |
| purification of the yada membrane anchor for secondary structure analysis and crystallization. | non-fimbrial adhesins, such as yersinia yada, moraxella uspa1 and a2, haemophilus hia and hsf, or bartonella bada, represent an important class of molecules by which pathogenic proteobacteria adhere to their hosts. they form trimeric surface structures with a head-rod-anchor architecture. whereas their head and rod domains may be of heterologous origin, their anchor domains are homologous and display the properties of autotransporters. conflicting topology models exist for these membrane anchors ... | 2006 | 16405993 |
| brucella outer membrane protein omp31 is a haemin-binding protein. | the expression of haemin-binding proteins (hbps) in the outer membrane is one of the strategies used by gram-negative bacteria to obtain iron from the host. no hbp has been described in brucella spp. we investigated whether omp31, an outer membrane protein from brucella with homology to hbps from bartonella quintana, is an hbp. soluble recombinant omp31 bound specifically to haemin-agarose, while an unrelated brucella protein (sura) did not. a similar experiment showed that native omp31 found in ... | 2006 | 16517201 |

| bartonella quintana endocarditis with positive serology for coxiella burnetii. | both bartonella quintana and coxiella burnetii are known to cause of blood culture negative endocarditis. in such case, the diagnosis is usually established by serology. a case of bartonella quintana endocarditis is described where the serology was falsely positive for coxiella burnetii. this case demonstrates the difficulty in distinguishing these two etiologic agents by routine serologic testing. | 2006 | 16386308 |
| antiangiogenic effect of erythromycin: an in vitro model of bartonella quintana infection. | bartonella quintana, the etiological agent of bacillary angiomatosis (ba), causes endothelial cell proliferation. erythromycin has dramatic effects on ba, and the effects are largely unexplained by the compound's bacteriostatic properties. our aim here was to evaluate the possibility that erythromycin alters angiogenesis. | 2006 | 16388485 |
| antibodies to bartonella vinsonii subsp. berkhoffii in moroccan dogs. | bartonella vinsonii subsp. berkhoffii is a fastidious microorganism that has been recognized as an emerging human and canine pathogen. we report for the first time on the prevalence of antibodies to b. vinsonii subsp. berkhoffii in domestic dogs from morocco. the overall seroprevalence was 38% (56 of 147 dogs tested). most of the seropositive dogs were stray dogs from rabat (36%, 8 of 22) and khenifra (47%, 47 of 101). antibodies against b. vinsonii subsp. berkhoffii were found infrequently amon ... | 2006 | 16474074 |
| a bartonella vinsonii berkhoffii typing scheme based upon 16s-23s its and pap31 sequences from dog, coyote, gray fox, and human isolates. | since the isolation of bartonella vinsonii subspecies berkhoffii from a dog with endocarditis in 1993, this organism has emerged as an important pathogen in dogs and as an emerging pathogen in people. current evidence indicates that coyotes, dogs and gray foxes potentially serve as reservoir hosts. based upon sequence differences within the 16s-23s its region and pap31 gene, we propose a classification scheme that divides b. vinsonii subsp. berkhoffii isolates into four distinct types. two conse ... | 2006 | 16460911 |
| plasmacytoid monocytes in cat scratch disease with special reference to the histological diversity of suppurative lesions. | it has been suggested that plasmacytoid monocytes (pmos) play an essential role in t-cell-dependent immune response. indeed, numerous pmos are found in close topographical association with epithelioid cell granulomas in hypersensitivity-type granulomas, such as tuberculosis and sarcoidosis. the key pathologic process in cat scratch disease (csd) usually involves a b-cell-associated granulomatous reaction. histologically, csd appears to exhibit a histopathologic diversity, including suppurative l ... | 2006 | 16352403 |
