Previously, we had identified non-OspA-OspB surface proteins of Borrelia burgdorferi that are targeted by the antibody-dependent complement-mediated killing mechanism. Here we demonstrate by Western blotting that one of these proteins, P35, is upregulated at the onset of stationary phase in vitro. Northern analysis revealed that the upregulation of P35 is(More)
The most likely animal source of a human case of cardiac disease in Washoe County, Nev., was identified by comparison of DNA sequences of three genes (citrate synthase gltA, 60-kDa heat shock protein gene groEL, and 16S rRNA gene) of Bartonella washoensis cultured from the human patient in question and of Bartonella isolates obtained from the following(More)
In a study of US patients with Lyme disease, immunoglobulin (Ig) G and IgM antibody responses to recombinant Borrelia burgdorferi antigen VlsE1 (rVlsE1), IgG responses to a synthetic peptide homologous to a conserved internal sequence of VlsE (C6), and IgM responses to a synthetic peptide comprising the C-terminal 10 amino acid residues of a B. burgdorferi(More)
Lyme disease, a global health concern, is caused by infection with Borrelia burgdorferi, B. afzelii, or B. garinii. The spirochete responsible for the disease in the United States is B. burgdorferi and is spread by the bite of an infected Ixodes tick. We utilized multiple two-dimensional gel techniques combined with proteomics to reveal the full humoral(More)
Borrelia burgdorferi can encode numerous lipoproteins of the Erp family. Although initially described as outer surface proteins, the technique used in that earlier study has since been demonstrated to disrupt bacterial membranes and allow labelling of subsurface proteins. Data are now presented from additional analyses indicating that Erp proteins are(More)
Members of the Borrelia burgdorferi paralogous gene family 54 (pgf 54) are regulated by conditions simulating mammalian infection and are thought to be instrumental in borrelial host survival and pathogenesis. To explore the activities of these genes in vivo, a comprehensive analysis of pgf 54 genes BBA64, BBA65, and BBA66 was performed to assess the(More)
As adherence and entry of a pathogen into a host cell are key components to an infection, identifying the molecular mechanisms responsible for cellular association will provide a better understanding of a microbe's pathogenesis. We previously established an in vitro model for Borrelia burgdorferi infection of human neuroglial cells. To expand on our earlier(More)
Borrelia burgdorferi exists in nature via an enzootic cycle whereby the organism must adapt to the diverse environmental conditions provided inside the arthropod transmission vector and the mammalian reservoir hosts. B. burgdorferi genes shown to be regulated by temperature, pH and/or cell density during the organism's growth in culture medium were assayed(More)
The Lyme disease spirochete, Borrelia burgdorferi, causes persistent mammalian infection despite the development of vigorous immune responses against the pathogen. To examine spirochetal phenotypes that dominate in the hostile immune environment, the mRNA transcripts of four prototypic surface lipoproteins, decorin-binding protein A (DbpA), outer surface(More)
Plasmid vectors were constructed that expressed an antigenic determinant of the glycoprotein gene of infectious hematopoietic necrosis virus (IHNV) as a fusion protein with the trpE protein of Escherichia coli. Insertion of Sau3AI fragments from the IHNV glycoprotein gene into trpE expression plasmids led to a fusion protein containing a hydrophilic segment(More)
