| bartonella bacilliformis stimulates endothelial cells in vitro and is angiogenic in vivo. | bartonellosis, a biphasic disease caused by motile intracellular bacteria, produces in its tissue phase a characteristic dermal eruption (verruga peruana) resulting from a pronounced endothelial cell proliferation. bacteria are found in the interstitium and within the cytoplasm of endothelial cells (rocha-lima inclusion). the aim of this study was to determine if bartonella bacilliformis produce a substance(s) that might be responsible for the vascular proliferation seen in the verruga. this was ... | 1990 | 1693472 |
| an epidemic of oroya fever in the peruvian andes. | between february and october 1987, a febrile illness killed 14 persons and seriously affected at least 14 others in shumpillan, a remote peruvian mountain village of 353 people. the illness was characterized by fever, headache, chills, and pallor. the fatality rate of untreated cases was 88%. the patients, 71% of whom were male, were 1-75 years of age. fatal illnesses progressed from lethargy to coma to death in 3-60 days. patients treated empirically with chloramphenicol survived. bartonella ba ... | 1990 | 2316791 |
| the agent of bacillary angiomatosis. an approach to the identification of uncultured pathogens. | bacillary angiomatosis is an infectious disease causing proliferation of small blood vessels in the skin and visceral organs of patients with human immunodeficiency virus infection and other immunocompromised hosts. the agent is often visualized in tissue sections of lesions with warthin-starry staining, but the bacillus has not been successfully cultured or identified. this bacillus may also cause cat scratch disease. | 1990 | 2233945 |
| a newly recognized fastidious gram-negative pathogen as a cause of fever and bacteremia. | we identified a motile, curved, gram-negative bacillus as the cause of persistent fever and bacteremia in two patients with symptomatic human immunodeficiency virus infection. the same organism was subsequently recovered from a bone marrow-transplant recipient with septicemia and from two immunocompetent persons with week-long febrile illnesses. all the patients recovered after antimicrobial therapy. | 1990 | 2233947 |
| blood parasites of mammals from papua new guinea. | thin blood smears were collected from 126 mammals representing four genera of marsupials and six genera of murid rodents. a species of hepatozoon was discovered in the new guinea spiny bandicoot (echymipera kalubu), trypanosome infections were found in three genera of rodent hosts and the prevalence of a rickettsial parasite of the genus grahamella was recorded in rodents from the genera rattus and melomys. dried blood samples also were taken and screened serologically for antibodies to arenavir ... | 1990 | 2338736 |
| transformation of rochalimaea quintana, a member of the family rickettsiaceae. | rochalimaea quintana is the only member of the family rickettsiaceae that can be grown in vitro. because of its relationship to the other members of this family, techniques developed to transform r. quintana might be applicable to the obligate intracellular bacteria of the rickettsiaceae. these procedures are critical to understanding mechanisms of pathogenesis and the nature of obligate intracellular growth. a transformation procedure for r. quintana has been established by using electroporatio ... | 1990 | 2394681 |
| bb65, a major immunoreactive protein of bartonella bacilliformis. | a 65 kda protein (bb65) has been identified as one of the major specific antigens of bartonella bacilliformis, the causative agent of bartonellosis which is a bacterial infectious disease of inhabitants of the andes. the gene encoding this antigen (7b2) was isolated from an expression library made directly from randomly generated fragments of b. bacilliformis genomic dna using bartonella antibodies raised in rabbits and sera of bartonellosis patients. the bartonella 7b2 gene was expressed in esc ... | 1990 | 1700634 |
| molecular characterization and proposal of a neotype strain for bartonella bacilliformis. | bartonella bacilliformis, the etiologic agent of bartonellosis, was characterized biochemically and by dna hybridization, guanine-plus-cytosine content, genome size, and 16s rrna sequencing. dnas from the two strains in our collection exhibited 97% relatedness in hydroxyapatite reactions done at 55 degrees c (optimal reassociation criterion) and 100% relatedness in reactions done at 70 degrees c (stringent reassociation criterion). there was no evidence of divergence within the related sequences ... | 1991 | 1715879 |
| 16s rrna sequences of bartonella bacilliformis and cat scratch disease bacillus reveal phylogenetic relationships with the alpha-2 subgroup of the class proteobacteria. | the primary structures of 16s rrnas of bartonella bacilliformis, an isolate of the cat scratch disease (csd) bacillus, and a strain phenotypically similar to the csd bacillus were determined by reverse transcriptase sequencing. these microorganisms were found to be members of the alpha-2 subgroup of the class proteobacteria. the sequence from b. bacilliformis was most closely related to the rrna of rochalimaea quintana (91.7% homology), the etiologic agent of trench fever. the sequence from the ... | 1991 | 1719021 |
| genetics of rickettsiae. | classical genetic approaches useful with free-living bacteria are difficult to apply to the rickettsiae. although rickettsial mutants have been isolated over the years, the genetic basis of these mutants is unknown, limiting their usefulness. the application of molecular biological techniques to rickettsial studies has provided the opportunity to isolate and study specific genes. genes encoding metabolic enzymes from rickettsiae were cloned in escherichia coli and shown to retain their regulator ... | 1991 | 1679397 |
| transformation and genomic restriction mapping of rochalimaea spp. | transformation procedures using electroporation were established for rochalimaea quintana. several cosmid/plasmids possessing the rk2 or rsf1010 origin of replication were successfully inserted. plasmid retention and replication were verified by antibiotic resistance and southern blot analysis. the highest level of transformation was obtained at a voltage field strength of 12.5 kv/cm with a pulse time of 10 miliseconds. transformation efficiency was low (0.3%) with approximately 10(5) transforma ... | 1991 | 1687634 |

| dermatopathologic findings in patients infected with hiv. | several inflammatory, infectious, and neoplastic conditions in hiv-infected patients are distinctive or require a biopsy for diagnosis. some differ subtly from similar conditions seen in noninfected patients. the exanthem of acute hiv infection cannot be diagnosed specifically on biopsy as its histologic appearance is similar to that of other viral exanthemata. a condition that closely resembles seborrheic dermatitis occurs in hiv-infected patients. plasma cells, necrotic keratinocytes, and leuk ... | 1992 | 1730173 |
| dendrocytes in verruga peruana and bacillary angiomatosis. | verruga peruana and bacillary angiomatosis are two cutaneous diseases characterized by angiomatous growths linked to the presence of rickettsia-like organisms. these lesions are currently considered to be endothelial hyperplasias and to share many features. by immunohistochemistry and computerized image analysis, we studied the presence of factor-xiiia-positive dendrocytes in these lesions and compared our data with similar research in capillary angiomas and normal skin. other cell lines were st ... | 1992 | 1348435 |
| serological response to "rochalimaea henselae" antigen in suspected cat-scratch disease. | there are no generally accepted diagnostic tests for cat-scratch disease (csd), the cause of which is unknown. during the development of an indirect fluorescence antibody (ifa) test for detection of antibodies to "rochalimaea henselae", sera from patients with csd were found to have high titres to r henselae antigens. further tests with this assay showed that 36 (88%) of 41 patients with suspected csd had serum titres of 64 or more to r henselae antigen, that there was a low prevalence (3%) of s ... | 1992 | 1351130 |

| detection of bartonella bacilliformis in cultures, blood, and formalin preserved skin biopsies by use of the polymerase chain reaction. | a polymerase chain reaction (pcr) is described for the detection of bartonella bacilliformis, the etiologic agent of bartonellosis, which cannot be identified biochemically. amplification of a genomic 231 bp bartonella dna sequence permitted specific identification of 12 bartonella isolates from peruvian bartonellosis patients as well as detection of bartonella dna in blood samples and formaldehyde preserved skin biopsies. specificity of amplification products was confirmed by restriction fragme ... | 1992 | 1470840 |
| immunocytochemical identification of rochalimaea henselae in bacillary (epithelioid) angiomatosis, parenchymal bacillary peliosis, and persistent fever with bacteremia. | we report the immunocytochemical identification of rochalimaea henselae, a newly recognized fastidious, gram-negative, warthin-starry-positive organism, as the common pathogen in bacillary angiomatosis (ba), bacillary peliosis (bp) of the liver and spleen, and persistent fever with bacteremia in immunocompromised patients. immunogenic proteins of the r. henselae strain isolated from the blood of a febrile immunocompromised patient with bp of the liver were used to produce primary immune serum in ... | 1992 | 1530106 |
| rochalimaea henselae sp. nov., a cause of septicemia, bacillary angiomatosis, and parenchymal bacillary peliosis. | nine strains of rochalimaea spp. that were isolated from patients over a period of 4.5 years were characterized for their enzyme activities, cellular fatty acid compositions, and dna interrelatedness among rochalimaea spp., bartonella bacilliformis, and afipia felis (cat scratch disease bacillus). all except one isolate, which was rochalimaea quintana, were determined to belong to a newly proposed species, rochalimaea henselae sp. nov. after recovery from clinical material, colonies required 5 t ... | 1992 | 1537892 |
| deformation factor: an extracellular protein synthesized by bartonella bacilliformis that deforms erythrocyte membranes. | bartonella bacilliformis, a hemotropic bacterium and the causative agent of the human disease bartonellosis, when incubated in a tryptone-based medium produces an extracellular factor, termed deformation factor (df), which induces extensive indentations and trenches in trypsinized erythrocyte membranes. the factor is stable during storage at 4 degrees c. it can be inactivated by proteases or brief heating to 70 to 80 degrees c, can be precipitated by ammonium sulfate, is nondialyzable, and is re ... | 1992 | 1541567 |
| rochalimaea henselae causes bacillary angiomatosis and peliosis hepatis. | recent studies have demonstrated that a newly described agent of persistent bacteremia, rochalimaea henselae, and the agent of bacillary angiomatosis are both closely related to rochalimaea quintana. bacillary peliosis hepatis seemed likely to have the same etiologic agent as bacillary angiomatosis. we sought these pathologic changes in patients from whom r henselae was cultivated. | 1992 | 1546924 |
| relapsing illness due to rochalimaea henselae in immunocompetent hosts: implication for therapy and new epidemiological associations. | two previously healthy, immunocompetent men had persistent rochalimaea henselae bacteremia with clinical relapses after courses of antibiotics to which the isolates were ultimately demonstrated susceptible in vitro. both had sustained tick bites prior to their illnesses, thus demonstrating an association not previously identified, although suspected. the first patient had relapsing fever, constitutional symptoms, and an episode of aseptic meningitis despite therapy with amoxicillin, then with do ... | 1992 | 1562660 |
| bacillary angiomatosis. a "new" disease with a broadening clinicopathologic spectrum. | bacillary angiomatosis (ba) is a reactive vasoproliferative lesion occurring almost exclusively in immunocompromised individuals in response to infection by a bacillus closely related to rochalimaea quintana. the commonest site of involvement is the skin, in the form of multiple erythematous nodules, but bacillary angiomatosis can also present in a wide variety of sites such as soft tissues, bone, lymph node, liver and spleen. some patients may present with persistent fever and bacteraemia. baci ... | 1992 | 1576430 |
| interactions between live bartonella bacilliformis and endothelial cells. | bartonella bacilliformis, a gram-negative, flagellated, motile bacterium, is the etiologic agent of verruca peruana. it is found within the verruca, where it can form large cytoplasmic (rocha-lima) inclusions in endothelial cells. previously, an activity has been described in homogenates of b. bacilliformis that in vitro increases the proliferation of endothelial cells and their production of tissue-type plasminogen activator (t-pa) and in vivo is angiogenic. the aim of the present study was to ... | 1992 | 1583335 |
| murine antibody responses distinguish rochalimaea henselae from rochalimaea quintana. | rochalimaea henselae causes persistent bacteremia, bacillary angiomatosis, and parenchymal bacillary peliosis. detection of a specific antibody response to r. henselae infection may represent an alternative to cultivation as a means of diagnosis. we assessed the specificity of induced murine antibodies for antigens from r. henselae and the closely related species r. quintana. groups of cd-1 mice were inoculated with whole organisms of six strains of r. henselae and two of r. quintana. pre- and p ... | 1992 | 1629326 |

| [bacillary peliosis in aids. anatomo-clinical study of 2 cases]. | the authors report two cases of peliosis hepatis, occurring in patients with aids, who presented a persistent fever and an hepatomegaly. the liver biopsies showed areas of peliosis, where bacilli were observed by warthin-starry stain. in one case, techniques of molecular biology allowed the identification of rochalimaea henselae, pathogen involved in bacillary angiomatosis. this rickettsia has been newly recognized in the united-states, where 17 cases of bacillary peliosis have been published in ... | 1993 | 8311862 |
| characterization of bartonella bacilliformis flagella and effect of antiflagellin antibodies on invasion of human erythrocytes. | bartonella bacilliformis is the etiologic agent of oroya fever in humans. flagellum-mediated motility has been postulated as a major virulence factor for invasion of host cells. to address this hypothesis, we purified and characterized flagella from strain kc584 and then assessed their role in human erythrocyte association and invasion. electron microscopy of the flagellar preparation showed a high concentration of filaments with a mean wavelength of 800 nm. sodium dodecyl sulfate-polyacrylamide ... | 1993 | 8225570 |
| ehrlichia chaffeensis and rochalimaea antibodies in kawasaki disease. | sera from 38 patients with kawasaki disease were tested for immunofluorescent antibodies to ehrlichia chaffeensis, rochalimaea henselae, and r. quintana oklahoma. only 2.5% of the patients tested positive for e. chaffeensis, and 5% were positive for r. henselae and r. quintana oklahoma. our data suggest that ehrlichia and rochalimaea spp. do not play a unique role in the etiology of kawasaki disease. | 1993 | 8263201 |
| cat-scratch disease mimicking rhabdomyosarcoma. | a 12-year-old boy who had injured his elbow presented with a lump in the epitrochlear area. originally thought to be a hematoma, then later myositis ossificans, this mass was actually a lymph node with large, reactive germinal centers. although stains for acid-fast bacilli, fungal organisms, bacteria, and cat-scratch disease were negative, serological testing for detection of rochalimaea henselae organisms found evidence of cat-scratch disease. we would like to remind orthopaedic surgeons to con ... | 1993 | 8265222 |
| [bacillary angiomatosis of the oral cavity in aids. a differential diagnosis of mucosal kaposi's sarcoma]. | the diagnosis of bacillary angiomatosis (ba) was performed on a biopsy of a reddish nodular lesion of the gingival mucosa, in a patient seropositive for the h.i.v. it was based on the histopathological features, and by the demonstration of bacilli both on the warthin-starry stain and the electron microscopic study. a treatment by erythromycin was quickly effective. ba is an opportunistic infection seen essentially in patients with a.i.d.s., most often causing cutaneous involvement. the causative ... | 1993 | 8278795 |

| endocarditis caused by rochalimaea henselae. | a case of community-acquired, culture-negative, infective endocarditis was diagnosed in a 57-year-old construction worker. small, pleomorphic gram-negative rods were seen in brown-hopps tissue gram stains and warthin-starry silver stains. the organism was identified as rochalimaea henselae by polymerase chain reaction amplification and sequencing of the 16s rdna gene sequence. this is the first report of infective endocarditis caused by r henselae. | 1993 | 8406424 |
| [rochalimaea henselae infection. febrile pancytopenia and hepatic peliosis in a patient with hiv infection]. | a case of rochalimaea henselae infection in an aids patient is reported. the r. henselae infection was revealed by febrile pancytopenia associated with liver and spleen enlargement. the diagnosis was made on the finding at histology of hepatic peliosis lesions. within these lesions warthin starry staining displayed bacilli that were identified as r. henselae. this case shows that all hiv-infected patients with these symptoms might be infected with this organism. | 1993 | 8511079 |
| morphologically variable bacilli of cat scratch disease are identified by immunocytochemical labeling with antibodies to rochalimaea henselae. | the identification of the causative organisms of cat scratch disease (csd) has been elusive. the demonstration of warthin-starry stain-positive pleomorphic bacilli in lymph nodes of patients with csd and recent serologic and epidemiologic data suggest an etiologic role of rochalimaea henselae in csd. the authors studied lymph node biopsy specimens of 46 patients with illnesses clinically consistent with csd and found pleomorphic bacilli in 15 (33%). the organisms were labeled by polyclonal rabbi ... | 1994 | 8178768 |
| disseminated cat-scratch disease: detection of rochalimaea henselae in affected tissue. | an immunocompetent 9-year-old boy with disseminated cat scratch disease involving spleen, cervical and abdominal lymph nodes, skull, and one clavicle is reported. antibodies to rochalimaea quintana and r. henselae were detected, at increasing, then decreasing concentration. dna extracted from the biopsied skull lesion was amplified by polymerase chain reaction and hybridized with species-specific oligonucleotides proving the presence of r. henselae in affected tissue. our findings suggest that r ... | 1994 | 8313920 |
| transformation of bartonella bacilliformis by electroporation. | bartonella bacilliformis is a member of the order rickettsiales, family bartonellaceae. the bacterium is an intracellular parasite of human erythrocytes. to date, members of the family bartonellaceae have not been transformed by standard chemical methods. we report the first successful transformation of a member of the bartonellaceae family, b. bacilliformis, by the method of electroporation. the optimal conditions for electroporation of b. bacilliformis include a field strength of 12.5 kv/cm an ... | 1994 | 7954111 |
| [recognition and identification of unknown infectious agents]. | the recognition and the identification of previously unrecognized infectious agents require a multidisciplinary approach to specify the nosologic entity of the disease and the epidemiological data, especially the modes of transmission and the risk factors, as well as to discover the microorganism in the laboratory. in the past 20 years, significant breakthroughs have been achieved in cellular cultures (growth factors), in immunology (monoclonal antibodies), and moreover in molecular biology, whi ... | 1994 | 7939294 |
| [cat-scratch disease and bacillary angiomatosis. an old and a new infectious disease with common etiology?]. | a review of cat-scratch disease (csd) and bacillary angiomatosis (ba) is presented on the basis of published articles. two newly identified bacteria--rochalimaea henselae and afipia felis--have been isolated from patients with csd. preliminary investigations seem to indicate that a. felis is an uncommon cause of the disease. csd may appear as a local suppurative lymphadenopathy or a systemic infection. ba is caused by rochalimaea species and may appear as cutaneous, mucous or visceral angiomas o ... | 1994 | 7998352 |
| rochalimaea antibodies in hiv-associated neurologic disease. | rochalimaea henselae, a recently described pathogen thought to cause syndromes as varied as bacillary angiomatosis, parenchymal bacillary peliosis, fever with bacteremia, and cat-scratch disease, is associated with cns diseases including cerebral and retinal bacillary angiomatosis, as well as cat-scratch-related encephalitis, myelitis, cerebral arteritis, and retinitis. we used a newly developed enzyme immunoassay and the polymerase chain reaction to investigate the association of r henselae inf ... | 1994 | 8035937 |
| ophthalmic manifestations of rochalimaea species. | rochalimaea henselae and r. quintana belong to the order rickettsiales and are thought to be responsible for trench fever, bacillary angiomatosis, and cat scratch disease. we recently examined four patients with intraocular inflammation of unknown origin. each patient had either unilateral or bilateral moderate loss of visual acuity ranging from 20/25 to counting fingers. bilateral intraocular inflammation manifested by anterior and posterior segment cells, retinal lesions, macular exudate, and ... | 1994 | 8053459 |
| bartonella bacilliformis or a similar organism and cardiovascular disease. | bartonella bacilliformis invades the endothelial lining of the cardiovascular system. damage to the red blood cells and white blood cells, the effects of the toxins, invasion of the brain and electrical charges induced by the organism so interfering with normal electrical stimulation of the heart may explain many of the features of cardiovascular disease (1-5). | 1994 | 7815963 |
| short report: verruga peruana in an italian traveler from peru. | we report a case of cutaneous bartonellosis in a 24-year-old italian woman. soon after returning from a seven-month stay in a central area of peru at an altitude of 3,130 meters, she developed high fever, headache, and muscle and joint pain that resolved after antibiotic therapy. two months later, she presented with disseminated, painless, firm, purple, subcutaneous nodules on the neck, shoulders, legs, left eyelid, and hard palate, some of which developed into vegetating lesions. the diagnosis ... | 1994 | 8116804 |

| identification of outer membrane proteins of bartonella bacilliformis. | purification of the outer membrane of bartonella bacilliformis by sucrose step gradient centrifugation and analysis by sodium dodecyl sulfate-polyacrylamide gel electrophoresis (sds-page) suggest that 14 proteins, ranging from 11.2 to 75.3 kda, are located in the outer membrane of the pathogen. on the basis of m(r)s, eleven of these proteins have counterparts which are labeled by extrinsic radioiodination of intact bartonellae, and two of the proteins are visibly sensitive to extrinsic proteinas ... | 1994 | 8188391 |
| histological and ultrastructural study of one case of oral bacillary angiomatosis in hiv disease and review of the literature. | bacillary angiomatosis (ba) is a new clinicopathological entity defined as a pseudo-neoplastic capillary proliferation secondary to an opportunistic infection by one of two rochalimaea sp.: r. quintana or r. henselae. although ba is a recently recognised entity, numerous cases have been reported. most of the patients affected are reported to have low absolute cd4 lymphocyte counts associated with aids. yet, very few oral cases associated or not with cutaneous lesions have been reported or simply ... | 1994 | 9135977 |
| atypical cat-scratch disease: diagnosis by a serologic test for rochalimaea species. | three patients with atypical manifestations of cat-scratch disease (csd) had the diagnosis supported by a newly available serologic assay for antibodies to rochalimaea henselae. previously, csd has been a diagnosis of exclusion because no confirmatory test was readily available. atypical or severe cases of csd have often required detailed (and expensive) clinical and laboratory investigation. the use of rochalimaea-specific serologic tests may help avoid extensive diagnostic testing or invasive ... | 1994 | 8153776 |
| [vascular tumors of the skin and soft tissue. overview of newly characterized entities and variants]. | this review summarizes vascular tumours of skin and soft tissues that have been characterised in recent years. although most of them are very rare, knowledge about their reproducible clinicopathological features is important to avoid diagnostic pitfalls. these lesions include: bacillary angiomatosis, a vasoproliferative, pseudoneoplastic infection of immunocompromised patients caused by rochalimaea henselae; tufted angioma, a variant of lobular capillary haemangioma characterised by a "cannon-ba ... | 1994 | 7824435 |
