| cat-scratch disease in veterinary-associated populations and in its cat reservoir in taiwan. | in taiwan, the first human case of cat-scratch disease (csd) was diagnosed by a serologic test in 1998. since then, no studies have been conducted to understand the epidemiology of the infection in taiwan. therefore, this study is the first epidemiologic survey of csd in cats and humans in this country. using veterinary-associated individuals as the study population, it was identified that 1.7% of them were seropositive for b. henselae, and residence was the only factor associated with seroposit ... | 2006 | 16641017 |
| bartonella henselae pap31, an extracellular matrix adhesin, binds the fibronectin repeat iii13 module. | bartonella henselae wound-associated infections suggest involvement of extracellular matrix molecules in adhesion and invasion. pap31 was previously identified as a hemin-binding protein. our recent studies suggest the protein is an adhesin that is recognized by the host's immune systems. in this study we examined the interactions of b. henselae pap31 with fibronectin (fn), heparin (hep), and human umbilical vein endothelial cells (huvecs). the cloned gene was expressed in escherichia coli, and ... | 2006 | 16622186 |
| [fleas and diseases transmissible to man]. | fleas are wingless insects that parasitize mammals and more rarely birds. they are able to jump and may bite people. adult fleas are hematophagous. the impact of fleas on public health is related to their ability to act as vectors for transmission of infectious agents during blood meals. the purpose of this article is to describe fleas and the diseases that they transmit to humans. special focus is placed on epidemiological aspects. | 2006 | 16615611 |
| bartonella species in rodents and shrews in the greater jakarta area. | in february 2004, we captured 221 rodents and shrews in the greater jakarta area as part of a study to determine the prevalence of rodent-associated vector-borne infections. microscopic examination of blood smears revealed 6% (13/218) to be positive for bartonella spp. the corresponding dna samples, either from blood blots or frozen spleen pieces and from fleas collected on these animals, were tested for evidence of bartonella infection by pcr, targeting the portions: 378bp and 930bp of the citr ... | 2005 | 16610656 |
| experimental infection of human body lice with acinetobacter baumannii. | the human body louse is currently recognized as a vector of rickettsia prowazekii, borrelia recurrentis, and bartonella quintana. previous studies have reported the isolation of acinetobacter baumannii from the body lice of homeless patients. to study how the body louse acquires a. baumannii, we infected a rabbit by infusing 2 x 10(6) colony-forming units of the louse strain of a. baumannii. two hundred body lice were infected by feeding on the bacteremic rabbit and compared with 200 uninfected ... | 2006 | 16606978 |

| bartonella and rickettsia in fleas and lice from mammals in south carolina, u.s.a. | species in the genera bartonella and rickettsia are vector-borne pathogens of humans and domestic animals. the natural reservoirs and enzootic transmission cycles of these bacteria are poorly known in south carolina. thirteen species of lice and fleas were collected from urban animals and screened for the presence of bartonella and rickettsia by pcr amplification using genus-specific primers. bartonella henselae was present in cat fleas (ctenocephalides felis) from virginia opossums (didelphis v ... | 2005 | 16599169 |
| rickettsial agents from parasitic dermanyssoidea (acari: mesostigmata). | mites are often overlooked as vectors of pathogens, but have been shown to harbor and transmit rickettsial agents such as rickettsia akari and orientia tsutsugamushi. we screened dna extracts from 27 mites representing 25 species of dermanyssoids for rickettsial agents such as anaplasma, bartonella, rickettsia, and wolbachia by pcr amplification and sequencing. dna from anaplasma spp., a novel bartonella sp., spiroplasma sp., wolbachia sp., and an unclassified rickettsiales were detected in mite ... | 2006 | 16596351 |
| molecular detection of microbes in nasal tissue of dogs with idiopathic lymphoplasmacytic rhinitis. | lymphoplasmacytic rhinitis (lpr) is a common histologic finding in dogs with chronic nasal disease; however, potential etiologies of this disorder have not been examined. we investigated the hypothesis that specific microbes contribute to clinical disease in dogs with lpr. paraffin-embedded nasal biopsies were obtained from 19 dogs with lpr, 10 dogs with nasal neoplasia, and 10 dogs with nasal aspergillosis. nucleic acids were extracted from paraffin blocks, and real-time quantitative polymerase ... | 2006 | 16594580 |
| co-detection of bartonella henselae, borrelia burgdorferi, and anaplasma phagocytophilum in ixodes pacificus ticks from california, usa. | presence of bartonella dna was explored in 168 questing adult ixodes pacificus ticks from santa cruz county, california. bartonella henselae type i dna was amplified from 11 ticks (6.55%); previously, two (1.19%) were found to be infected with borrelia burgdorferi and five (2.98%) with anaplasma phagocytophilum. detection of b. henselae was not dependent on co-infection. the present study offers additional evidence that ixodes spp. ticks may act as hosts and possibly vectors for b. henselae. | 2006 | 16584332 |
| pet ownership in immunocompromised children--a review of the literature and survey of existing guidelines. | pet ownership has been associated with both emotional and physical health benefits. however, owning pets may also pose health risks to immunocompromised patients through zoonotic transmission of disease. our initial impression was that there is a lack of any evidence base in information given by health care professionals regarding these risks. we therefore aimed to produce evidence-based guidelines addressing this issue. a pubmed search was undertaken and a variety of literature on zoonoses revi ... | 2006 | 16581294 |
| anti-francisella tularensis dna aptamers detect tularemia antigen from different subspecies by aptamer-linked immobilized sorbent assay. | aptamers are powerful candidates for molecular detection of targets due to their unique recognition properties. these affinity probes can be used to recognize and bind to their targets in the various types of assays that are currently used to detect and capture molecules of interest. they are short single-stranded (ss) oligonucleotides composed of dna or rna sequences that are selected in vitro based on their affinity and specificity for the target. using combinatorial oligonucleotide libraries, ... | 2006 | 16550191 |

| bacillary angiomatosis caused by bartonella quintana. | bacillary angiomatosis is a disorder of neovascular proliferation involving skin and lymph nodes of immunosuppressed patients. bartonella henselae or bartonella quintana have been inculpated as causative by direct culture or pcr amplification of dna sequences. here, we report the clinical evolution of a patient infected with human immunodeficiency virus (hiv) whose b. quintana infection was diagnosed by pcr. | 2005 | 16481531 |
| occurrence of bartonella henselae and bartonella quintana among human immunodeficiency virus-infected patients. | the purpose of this study was to determine the seroprevalence against bartonella henselae and bartonella quintana among a risk group, patients with hiv infection, and to identify the epidemiological factors involved. our data indicate that the prevalence of bartonella infection among hiv-infected patients is much greater than that in the healthy population of the same area and that bartonella infection should be considered in the differential diagnosis for patients with hiv disease. | 2005 | 16481530 |
| bartonella bacilliformis groel: effect on growth of human vascular endothelial cells in infected cocultures. | bartonella are the only bacteria known to induce angioproliferative lesions of the human vasculature and liver during infection. previous work from our lab suggests that groel participates in the mitogenic response observed in huvec cultures supplemented with the soluble fraction of bartonella bacilliformis. work in this study shows that exposure to high concentrations of the fraction is actually cytotoxic for huvecs. to analyze this phenomenon, live b. bacilliformis-huvec cocultures were employ ... | 2005 | 16481529 |
| production of recombinant protein pap31 and its application for the diagnosis of bartonella bacilliformis infection. | tropical bartonellosis is a highly fatal epidemic and endemic infectious disease that occurs throughout the communities of the andes mountains in south america. the disease is caused by the facultative intracellular bacteria, bartonella bacilliformis. the emergence of bartonellosis in new geographic areas and an increase in the number of reported cases suggest the need for a rapid test for epidemiologic study and investigation of the disease burden. the objective of this research is to develop a ... | 2005 | 16481528 |
| bartonellae as elegant hemotropic parasites. | bartonella species are hemotropic bacterial parasites of a wide range of mammals that occasionally cause disease in humans. the low prevalence of clinical manifestations compared to the high prevalence of infection underlines the elegance of these parasites that carefully exploit their hosts in a manner that optimizes their transmission. recent research efforts have begun to determine the strategies involved in this exploitation, and significant progress has been made in unraveling an unusually ... | 2005 | 16481527 |
| 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 |

| bartonella henselae infection associated with guillain-barre syndrome. | this is the first report of guillain-barré syndrome (gbs) related to bartonella henselae infection. a 10-year-old girl had difficulty walking and marked myalgia. the search for all causes known to trigger gbs was negative. she was treated with intravenous immunoglobulins and recovered. because she lived in a rural area and had a history of kitten contact, a specific serology for b. henselae infection was performed and confirmed an ongoing infection. she did not show any clinical typical feature ... | 2006 | 16395116 |
| 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 |
| 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 |
| 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 |
| 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 |
