  • The Relapsing Fever Agent Borrelia Hermsii Has Multiple
    Copyright Q 1992 by the Genetics Societyof America The Relapsing Fever AgentBorrelia hermsii Has Multiple Copiesof Its Chromosome and Linear Plasmids Todd Kitten and Alan G. Barbour Departments of Microbiology and Medicine, The Universityof Texas Health Science Center, Sun Antonio, Texas 78284 Manuscript received March 17, 1992 Accepted for publicationJune 25, 1992 ABSTRACT Borrelia hermsii, a spirochete which causes relapsing fever in humans and other mammals, eludes the immune responseby antigenic variationof the “Vmp” proteins.This occurs by replacement of an expressed vrnp gene with a copy of a silent vrnp gene. Silent and expressedvrnp genes are located on separate linearplasmids. To further characterize vrnp recombination, copy numbers were determined for two linear plasmids and for the l-megabase chromosome by comparing hybridization of probes to native DNA with hybridization to recombinant plasmids containing borrelial DNA. Plasmid copy numbers were also estimated by ethidium bromide fluorescence. Total cellular DNA content was determined by spectrophotometry. For borreliasgrown in mice, copy numbers and 95% confidence intervals were 14 (12-17)for an expression plasmid,8 (7-9) for a silent plasmid, and 16 (13-18) for the chromosome. Borrelias grown in broth mediumhad one-fourth to one-half this number of plasmids and chromosomes. Staining of cells with4’,6-diamidino-2-phenylindole revealed DNA to be distributed throughout most of the spirochete’s length. These findings indicate that borrelias organize their total cellular DNA into several complete genomes and thatcells undergoing serotype switches do one or more of the following: (1) coexpress Vmps from switched and unswitched expression plasmids for at least three to five generations, (2)suppress transcription from some expressionplasmid copies, or (3) partition expression plasmids nonrandomly.The lower copy number ofthe silentplasmid indicates that nonreciprocal Vmp gene recombination may result from loss of recombinant silent ” plasmids by segregation.

Borrelia burgdorferi sensu stricto (Bbss) is considered the primary agent of Lyme disease in North America. However, multiple genetically diverse Borrelia species encompassing the Borrelia burgdorferi sensu lato (Bbsl) complex and the Relapsing Fever Borrelia (RFB) group are capable of causing tickborne disease. We report preliminary results of a serological survey of previously undetected species of Bbsl and RFB in California and Mexico using a novel immunoblot technique. Methods: Serum samples were tested for seroreactivity to specific species of Bbsl and RFB using an immunoblot method based on recombinant Borrelia membrane proteins, as previously described. A sample was recorded as seropositive if it showed immunoglobulin M (IgM) and/or IgG reactivity with at least two proteins from a specific Borrelia species.

This thesis may not be reproduced in whole or in part, by photocopy or other means, without the permission of the author. ii Supervisory Committee Investigating the Role of Pallilysin in the Dissemination of the Syphilis Spirochete Treponema pallidum by Yavor Denchev Bachelor of Science, University of Victoria, 2011 Supervisory Committee Dr. Caroline Cameron, Department of Biochemistry and Microbiology Supervisor Dr. Terry Pearson, Department of Biochemistry and Microbiology Departmental Member Dr. John Taylor, Department of Biology Outside Member iii Abstract Supervisory Committee Dr. Caroline Cameron, Department of Biochemistry and Microbiology Supervisor Dr. Terry Pearson, Department of Biochemistry and Microbiology Departmental Member Dr. John Taylor, Department of Biology Outside Member Syphilis is a global public health concern with 36.4 million cases worldwide and 11 million new infections per year. It is a chronic multistage disease caused by the spirochete bacterium Treponema pallidum and is transmitted by sexual contact, direct contact with lesions or vertically from an infected mother to her fetus. T. pallidum is a highly invasive pathogen that rapidly penetrates tight junctions of endothelial cells and disseminates rapidly via the bloodstream to establish widespread infection. Previous investigations conducted in our laboratory identified the surface-exposed adhesin, pallilysin, as a metalloprotease that degrades the host components laminin (major component of the basement membrane lining blood vessels) and fibrinogen (primary component of the coagulation cascade), as well as fibrin clots (function to entrap bacteria and prevent disseminated infection).
