[a case of cat scratch disease identified by an elevated bartonella henselae antibody level using enzyme immunoassay].a 68-year-old male was admitted to our hospital because of fever and a 2-week history of inguinal adenomegaly. since he owned a cat, cat scratch disease was suspected. but it was necessary to distinguish cat scratch disease from lymphoma type adult t-cell leukemia because he showed a high level of antibody against htlv-1. an excisional biopsy of the inguinal node was performed. histopathologic examination revealed abscess-forming granulomatous lymphadenitis compatible with cat scratch disease. a ...19979394562
inflammatory mass of the optic nerve head associated with systemic bartonella henselae infection. 19979400801
molecular epidemiology of bartonella infections in patients with bacillary angiomatosis-peliosis.bacillary angiomatosis and bacillary peliosis are vascular proliferative manifestations of infection with species of the genus bartonella that occur predominantly in patients infected with the human immunodeficiency virus. two species, b. henselae and b. quintana, have been associated with bacillary angiomatosis, but culture and speciation are difficult, and there has been little systematic evaluation of the species-specific disease characteristics. we studied 49 patients seen over eight years w ...19979407154

experimental and natural infection with bartonella henselae in domestic cats.domestic cats were experimentally infected with culture propagated bartonella henselae by intradermal (i.d.) and intravenous (i.v.) routes. cats were more efficiently infected by the i.d. (8/8 cats) than by the i.v. (2/16) route. bacteremia was detected 1-3 weeks following inoculation and lasted for most cats for 1-8 months. however, one naturally infected cat was observed for 24 months and was found to be cyclically bacteremic, with bacterial levels varying one hundred fold or more from one per ...19979023040
bacillary angiomatosis: presentation of six patients, some with unusual features.bacillary angiomatosis (ba) is an unusual systemic vascular proliferation seen predominantly in patients with the acquired immunodeficiency syndrome. these vascular lesions are probably due to infection with a bartonella species, most often b. henselae and, in some patients, b. quintana. ba is treatable and often curable, but without therapy, may be life-threatening. clinically, the lesions, when superficial, are said to often resemble pyogenic granulomas, appearing polypoid histologically with ...19979039296
isolation of bartonella (rochalimaea) henselae: effects of methods of blood collection and handling.bartonella (rochalimaea) henselae causes cat-scratch disease, bacillary angiomatosis, peliosis hepatis, and fever in humans. b. henselae can be difficult to culture axenically, and as many as 5 weeks may be required before colonies are visible. we compared how different methods of blood collection and handling affect isolation of this pathogen. blood specimens from b. henselae-infected cats were collected in both edta and isolator blood-lysis tubes and were subsequently plated onto rabbit blood- ...19979041385
detection and identification of two bartonella henselae variants in domestic cats in germany.to determine the prevalence of bacteremia caused by bartonella henselae in domestic cats in the region of freiburg, germany, we investigated culture of blood from 100 cats from 89 different households over a 12-month period. b. henselae could be isolated from 13% (13 of 100) of these cats. in eight households with two cats each and in one household with three cats, b. henselae bacteremia was found either in all of the animals or in none of the animals. positive cultures were more likely to be fo ...19979041393
the expanding spectrum of bartonella infections: ii. cat-scratch disease.recent advancements and developments in molecular biotechnology have allowed more precise reclassification of many microorganisms. with the use of these new taxonomy tools, several organisms previously thought to belong to other genera have been recently described as bartonellae. of the 11 organisms now described as bartonella spp., only four have been shown to be pathogenic for humans. table 1 lists the four bartonella human pathogens along with the their known epidemiology and the scope and ra ...19979041596
in vitro susceptibilities of bartonella henselae, b. quintana, b. elizabethae, rickettsia rickettsii, r. conorii, r. akari, and r. prowazekii to macrolide antibiotics as determined by immunofluorescent-antibody analysis of infected vero cell monolayers.the in vitro susceptibilities of bartonella (rochalimaea) henselae, b. quintana, b. elizabethae, rickettsia akari, r. conorii, r. prowazekii, and r. rickettsii to different concentrations of azithromycin, clarithromycin, dirithromycin, erythromycin, and roxithromycin in vero cell cultures were evaluated. bartonella and rickettsia spp. were allowed to initiate infection of the antibiotic-free vero cell monolayers, which were maintained in 16-chamber microscope slides in the absence of antibiotics ...19979055996

hepatosplenic cat-scratch disease and abdominal pain.there have been several recent reports that cat-scratch disease (csd) causes a multiplicity of atypical clinical syndromes. we recently diagnosed hepatosplenic csd in a child who was seen with fever and abdominal pain. we report this case and 10 other patients with hepatosplenic csd and highlight the importance of abdominal pain in this clinical entity.19979076813
[cat-scratch disease. a report of 4 cases and a review of the literature].four cases of cat-scratch diseases are here reported and a review of the literature is made. the disease, apart from its typical presentation form as a usually self-limited regional lymph node enlargement, can occasionally spread and involve several organs systems. indirect immunofluorescence serological tests have been of help for its diagnosis and should be included among the diagnostic criteria for the disease. in particular cases, nuclear magnetic resonance can be useful to suggests the diag ...19979102668
cat-scratch disease and related clinical syndromes.bartonella (rochalimaea) henselae is a common cause of cat-scratch disease. this newly identified bacterium is also the cause of several other clinical syndromes, including bacillary angiomatosis, bacillary peliosis hepatitis and splenitis, and acute and relapsing bacteremia. a high percentage of young cats carry b. henselae. fortunately, serious complications of b. henselae infections are rare in immunocompetent patients. cat-scratch disease is usually a self-limited illness that does not neces ...19979105205
bartonella spp. as emerging human pathogens.members of the genus bartonella (formerly rochalimaea) were virtually unknown to modern-day clinicians and microbiologists until they were associated with opportunistic infections in aids patients about 6 years ago. since that time, bartonella species have been associated with cat scratch disease, bacillary angiomatosis, and a variety of other disease syndromes. clinical presentation of infection with bartonella ranges from a relatively mild lymphadenopathy with few other symptoms, seen in cat s ...19979105751
pathogenetic role of phagocytic abnormalities in human virus immunodeficiency infection: possible therapeutical approaches. a review.polymorphonuclear cells (pmn) and monocytes/macrophages (m/m) represent the first defence line against invading microorganisms. both phagocytic cell functions are precociously compromised in human immunodeficiency virus (hiv)-infected subjects, thus leading to infectious and neurological complications in the late stages of disease. among intracellular pathogens, emerging bacteria such as bartonella henselae and rhodococcus equi can cause peculiar clinical pictures, i.e. the bacillary parenchimal ...19979130002
flea-borne rickettsioses: ecologic considerations.ecologic and economic factors, as well as changes in human behavior, have resulted in the emergence of new and the reemergence of existing but forgotten infectious diseases during the past 20 years. flea-borne disease organisms (e.g., yersinia pestis, rickettsia typhi, r. felis, and bartonella henselae) are widely distributed throughout the world in endemic-disease foci, where components of the enzootic cycle are present. however, flea-borne diseases could reemerge in epidemic form because of ch ...19979284376
bartonellosis in ecuador: serosurvey and current status of cutaneous verrucous disease.human bartonellosis is a classically biphasic disease caused by infection with the alpha-2 proteobacteria bartonella bacilliformis, which is phylogenetically related to the etiologic agents of cat scratch disease, bacillary angiomatosis, and trench fever. in ecuador, typical bartonellosis has remained endemic for the past century in highland provinces near the peruvian border. during the past six years, public health officials have noted an increasing number of atypical cases in which monophasic ...19979288812

[cat-scratch disease: historical, clinical, phylogenetic and taxonomic aspects].the cat-scratch disease (csd) is known as a nosological entity since 1950. it was diagnosed by the clinical symptoms, epidemiologic data, and the intracutaneous test of hanger and rose. the aetiologic agent is bartonella (formerly rochalimaea) henselae occurring in thirty to fifty percent of healthy cats. the gramnegative alpha-2-proteobacteria cause the csd but also fever in healthy humans. patients suffering from aids show bacillary angiomatosis, bacillary peliosis hepatis, endocarditis, and s ...19979198973
[cat scratch disease and associated infections].cat scratch disease (csd) was first described in france by debré et al. in 1950, yet the causative bacterial agent of csd remained obscure until 1992, when bartonella (formerly rochalimaea) henselae was implicated in csd by serological and microbiologic studies. b. henselae had been linked initially to bacillary angiomatosis (ba), but also bacillary peliosis, relapsing bacteremia and endocarditis. cats are healthy carriers of b. henselae and b. clarridgeiae, and can be bacteremic for months to y ...19979203735
molecular diagnosis of deep nodular bacillary angiomatosis and monitoring of therapeutic success.a 51-year-old human immunodeficiency virus (hiv)-positive male patient (cdc stage 3c) had had a painful nodule on his external ankle joint for 10 months. a biopsy suggested bacillary angiomatosis, but kaposi's sarcoma could not be excluded. rods were detectable in lesional skin by a warthin-starry stain. a 298 base pair (bp) gene fragment specific for bartonella species was amplified from lesional skin and direct nucleotide sequence analysis of the amplification product clearly identified barton ...19979205511
experimental infection of young specific pathogen-free cats with bartonella henselae.eighteen 12-week-old specific pathogen-free cats, blood culture- and serum antibody-negative for bartonella henselae, were randomly allocated to groups and were intravenously inoculated with 10(10) (group 1), 10(8) (group 2), or 10(6) (group 3) b. henselae or with saline (group 4) or were not inoculated (group 5). cats were humanely killed at 2, 4, 8, 16, and 32 weeks after inoculation. all b. henselae-inoculated cats were bacteremic by 2 weeks after infection. bacteremia persisted until 32 week ...19979207369
application of polymerase chain reaction assay in the diagnosis of orbital granuloma complicating atypical oculoglandular cat scratch disease.parinaud oculoglandular syndrome is uncommon. most cases are caused by cat scratch disease (csd), recently discovered to be associated with the pathogen bartonella henselae. before isolation of the micro-organism, diagnosis relied on the presence of characteristic clinical features. however, atypical cases could cause diagnostic problems. with the development of an indirect fluorescent antibody test and polymerase chain reaction (pcr) assay, oculoglandular csd can be diagnosed readily.19979224472
rapid polymerase chain reaction-based detection of the causative agent of cat scratch disease (bartonella henselae) in formalin-fixed, paraffin-embedded samples.bartonella (formerly rochalimaea) henselae (bh) plays a central role in cat scratch disease. a polymerase chain reaction (pcr)-based assay that can detect bh dna in formalin-fixed, paraffin-embedded (ff-pe) samples would have utility in the evaluation of processed lymph nodes suggestive of this disorder. fresh or ff-pe cultures of bh and related species were analyzed. thirteen lymph nodes (12 ff-pe and one fresh cell suspension) with necrotizing suppurative granulomatous inflammation and seven f ...19979224751
the 75-kilodalton antigen of bartonella bacilliformis is a structural homolog of the cell division protein ftsz.a genomic library of bartonella bacilliformis was constructed and screened with human anti-bartonella serum from a patient with the chronic, verruga peruana phase of bartonellosis. an immunoreactive clone isolated from this library was found to code for a 591-amino-acid protein with a high degree of sequence similarity to the ftsz family of proteins. the degree of amino acid identity between the b. bacilliformis protein (ftsz[bb]) and the other ftsz proteins is especially pronounced over the n-t ...19979226264
molecular diagnosis of cat scratch disease: a two-step approach.amplification of bartonella henselae dna has been proposed as a diagnostic test for cat scratch disease (csd). the sensitivities of the following three pcr assays were compared. pcr/rrna with universal primers amplifies part of the 16s rrna gene, followed by hybridization with a specific b. henselae probe; pcr/cs and pcr/hsp amplify portions of the glta and the htra genes, respectively, each followed by restriction fragment length polymorphism analysis. the threshold of detection of b. henselae ...19979230357
pitfalls and fallacies of cat scratch disease serology: evaluation of bartonella henselae-based indirect fluorescence assay and enzyme-linked immunoassay.the diagnostic value of the detection of immunoglobulin g (igg) and igm by bartonella henselae-based indirect fluorescence assay (ifa) and enzyme-linked immunoassay (eia) for the diagnosis of cat scratch disease (csd) was evaluated. the ifa was performed either with b. henselae that was cocultivated for a few hours with vero cells or with noncocultivated b. henselae as the antigen. additionally, the performance of a bartonella pcr hybridization assay based on the 16s rrna gene was determined and ...19979230358
pcr amplification and comparison of nucleotide sequences from the groesl heat shock operon of ehrlichia species.degenerate pcr primers derived from conserved regions of the eubacterial groesl heat shock operon were used to amplify groesl sequences of ehrlichia equi, ehrlichia phagocytophila, the agent of human granulocytic ehrlichiosis (hge), ehrlichia canis, bartonella henselae, and rickettsia rickettsii. the groesl nucleotide sequences were less conserved than the previously determined 16s rrna gene sequences of these bacteria. a phylogenetic tree derived from deduced groel amino acid sequences was simi ...19979230387
coinfection with bartonella clarridgeiae and bartonella henselae and with different bartonella henselae strains in domestic cats.bartonella clarridgeiae and several strains of bartonella henselae, the agent of cat scratch disease, with variations in the 16s rrna gene have been found to infect the blood of cats. an epidemiologic study of bartonella infection in domestic french cats revealed that of 436 cats sampled, 5 cats (1.1%) were coinfected with b. henselae and b. clarridgeiae and 2 cats (0.5%) were coinfected with two strains of b. henselae with variations in the 16s rrna gene, b. henselae type i and type ii. in an i ...19979230394
bartonellosis and human immunodeficiency disease (aids): l-forms as persisters, activating factors, and mechanism of disease.bartonella, genus proteus, can cause immunodepressive disease. the organisms, in parasitized red blood cells, may invade the brain and every other system and space in the human body. bartonella henselae is proposed to have a role in the pathogenesis of acquired immunodeficiency syndrome (aids) encephalopathy. bartonella bacilliformis produces two known toxins that can induce spasm and angiomatosis, respectively, and manifest as diseases associated with symptomatic aids. the skin lesions of barto ...19979247895
bacillary angiomatosis, cat-scratch disease, and bartonellosis: what's the connection? 19979248882
sternal abscess due to bartonella (rochalimaea) henselae in a renal transplant patient.bartonella henselae, previously called rochalimaea henselae, is the causative agent of cat scratch disease (csd) in immunocompetent subjects and bacillary angiomatosis in immunocompromised ones. bone lesions are common in bacillary angiomatosis, but not in csd. we present the case of a patient with a renal transplant treated by immunosuppressive therapy who developed a sternal abscess with a histological pattern of csd. the ct pattern was that of a lytic bone lesion with adjacent fluid collectio ...19979259103
immunologic response to bartonella henselae as determined by enzyme immunoassay and western blot analysis.bartonella henselae is now regarded as the etiologic agent of cat-scratch disease and a cause of bacillary angiomatosis. we examined the human immune response to bartonella henselae infection using a newly developed enzyme immunoassay (eia) and a western blot procedure using outer-membrane proteins. the eia showed 98.6% and 91.4% agreement with an indirect fluorescence method (ifa) for detection of igm and igg antibodies, respectively. by using western blot analysis, reactivity to an 8-kd band s ...19979260762

carboxyl-terminal processing protease for the d1 precursor protein: cloning and sequencing of the spinach cdna.a previous study has demonstrated that the carboxyl-terminal (c-terminal) processing protease in spinach for the d1 precursor protein (pdl) of the photosystem ii reaction center is a monomeric protein of about 45 kda. based on the amino acid sequence data of the purified protease, a cdna clone encoding the enzyme has been identified and sequenced, from a spinach green leaf cdna library. in order to determine the 5' end of the transcript, the rapid amplification of cdna end (5'-race) technique wa ...19968616242
new serotype of bartonella henselae in endocarditis and cat-scratch disease.the fastidious nature of bartonella henselae is such that demonstration of clinical infection relies mainly on serological or molecular biological methods. only five isolates have been obtained from patients with cat-scratch disease (csd) and none from endocarditis.19968618486
[cat-scratch disease and other infections caused by bartonella species].bartonella henselae, the causative agent of cat-scratch disease, was identified recently by dna amplification techniques. several other bartonellae (most of which were called rochalimaea before) cause disease in humans: b. bacilliformis (carrion's disease), b. elizabethae (endocarditis) and b. quintana (bacillary angiomatosis and peliosis, chronic bacteraemia and endocarditis, trench fever). b. henselae is transmitted to humans by scratch or bite of a bacteraemic, but asymptomatic, cat, which ev ...19968618634

emerging bacterial zoonotic and vector-borne diseases. ecological and epidemiological factors.among the etiologic agents of emerging infectious diseases are several bacterial organisms that naturally reside in animal and arthropod hosts. the most compelling emerging bacterial zoonotic and vector-borne diseases in the united states are lyme disease; a southern erythema migrans-like illness; human monocytic ehrlichiosis; human granulocytic ehrlichiosis; a novel cat flea-associated typhus group rickettsiosis; bartonelloses of immunocompetent and immunocompromised persons, particularly with ...19968627968

isolation of bartonella henselae from domestic cats in japan.during the period from january to march 1995, the authors first isolated bartonella henselae from the blood of three (9.1%) of 33 domestic cats in japan. the three cats were a 1.5-year male pet cat-old with urinary retention, and 6-year-old female pound and age-unknown female pet cats with no abnormalities. the blood was taken in a lysis-centrifugation tube (wampole isolator tube) and cultured on 5% rabbit-blood heart infusion agar plates at 35 degrees c in the 5% co2 atmosphere. visible tiny ro ...19968645765
bartonella (rochalimaea) infections: beyond cat scratch.five species of bartonella have been found to infect humans, henselae, quintana, elizabethae, bacilliformis, and vinsonii. the most common of these in north america are bartonella quintana and bartonella henselae, the agents of trench fever, bacillary angiomatosis, and parenchymal peliosis, and in the case of b. henselae cat-scratch disease. b. bacilliformis is endemic in peru and ecuador, where it causes oroya fever or carrion's disease. new methods of diagnosing bartonella infections have resu ...19968712787
bartonella (rochalimaea) quintana causing fever and bacteremia in an immunocompromised patient with non-hodgkin's lymphoma.a 48-yr-old man with stage iv non-hodgkin's lymphoma, became neutropenic following chemotherapy and developed a fever. his blood cultures were processed to enhance the yield of fastidious bacteria. a slow-growing, capnophilic gram-negative rod was isolated. the febrile episode was treated with cefotaxime, imipenem and vancomycin and resolved. the bacterial isolate was identified as bartonella (rochalimaea) quintana by 16s-rdna gene sequencing. the isolate showed 99.8% sequence homology with the ...19968714279
