| 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 |

| 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 |

| the line blot: an immunoassay for monoclonal and other antibodies. its application to the serotyping of gram-negative bacteria. | a procedure is described for assaying antibodies based on the application of antigen to nitrocellulose as a line with an ink pen point. the method requires no expensive apparatus, is easy to perform, and requires less than 0.25 micrograms of antigen per assay. more than 45 antigens can be assayed simultaneously with a single antibody. antigens can be applied as purified proteins, extracts, or sodium dodecyl sulfate solubilized extracts. the application of the line blot assay for the detection of ... | 1989 | 2607166 |
| trench fever in belfast, and the nature of the 'relapsing fevers' in the united kingdom in the nineteenth century. | some evidence is assembled to suggest that trench fever, an infection with a strain of rochalimaea, if not quintana, then vinsonii, was present in belfast in the first half of the nineteenth century in endemic and epidemic form. it may have amounted at times to one half or more of 'fever'. this may account for the comparatively low mortality in some years from 'fever'. the phrase 'relapsing fever' in the nineteenth and twentieth century medical literature of the united kingdom should not be take ... | 1989 | 2672525 |

| bacillary (epithelioid) angiomatosis and concurrent kaposi's sarcoma in acquired immunodeficiency syndrome. | two patients with acquired immunodeficiency syndrome developed simultaneous kaposi's sarcoma and bacillary (epithelioid) angiomatosis. the distinguishing clinical and histologic features of these two vascular proliferations associated with human immunodeficiency virus disease are described. the lesions of bacillary (epithelioid) angiomatosis contained bacteria, while the lesions of kaposi's sarcoma did not. with erythromycin therapy, the lesions of bacillary (epithelioid) angiomatosis cleared, w ... | 1989 | 2817918 |
| selected observations on rickettsiae and their host cells. | the study of the interaction between rickettsiae and their host cells is in its infancy. members of the genera rickettsia, coxiella and rochalimaea show considerable diversity in host cell range (in vivo vs. in vitro), kind of association with host cell (pericellular, intracellular), mode of entry, interactions with various host cell membranes, intracellular localization (intraphagosomal, free in cytoplasm, intranuclear), adaptation to preferred microhabitat (e.g., optimal ph for enzymes), detai ... | 1986 | 2871738 |

| analysis and preparation of bartonella bacilliformis antigens. | twenty-four antigens of bartonella bacilliformis, a bacterium which causes bartonellosis in residents of high altitude valleys of the andes, were identified by immunoblot and immunoprecipitation using rabbit anti-bartonella sera as well as sera of patients. the antigens were designated according to their relative molecular mass which ranged from 16 to 160 kda. twelve antigens were detected by antibodies in sera of bartonellosis patients using immunoblot, of which six antigens were detected by im ... | 1988 | 3044156 |

| seasonal and age distributions of babesia, hepatozoon, trypanosoma and grahamella species in clethrionomys glareolus and apodemus sylvaticus populations. | four common blood parasites belonging to the genera babesia, hepatozoon, trypanosoma and grahamella were detected in sympatric populations of clethrionomys glareolus and apodemus sylvaticus. seasonal changes in the abundance of hosts and parasites were monitored in a longitudinal field survey for 18 months. all parasites in both hosts showed similar seasonal patterns with most transmission occurring in summer and autumn and ceasing in winter. amongst aged subsets of each host population, hepatoz ... | 1986 | 3537923 |
| verruga peruana mimicking malignant neoplasms. | we have shown that in some cases fully developed florid verruga peruana nodules, as well as late-resolving, deeply situated lesions, can histologically suggest a variety of tumors to experienced pathologists. the compact proliferation of endothelial cells characteristic of florid verruga lesions can give rise to two pseudoneoplastic histologic patterns. one consists of sheets or islands of cells arranged in an epithelioid or pseudoepithelioid pattern (cases 1 and 2) in which the following histol ... | 1987 | 3631453 |
| entry of bartonella bacilliformis into erythrocytes. | bartonella bacilliformis, which causes the human diseases oroya fever and verruga peruana, binds to human erythrocytes in vitro and produces substantial and long-lasting deformations in erythrocyte membranes, including cone-shaped depressions, trenches, and deep invaginations. the deforming force is probably provided by the polar flagella of these highly motile bacteria. deep invaginations containing bacteria are commonly seen, and membrane fusion at the necks of the invaginations leads to the f ... | 1986 | 3770946 |
