A Borrelia burgdorferi, uma bactéria da família Spirochaetaceae, é o agente etiológico da doença de Lyme Borreliose sendo a doença mais comum na Europa e nos EUA transmitida pela carraça Ixodes sp. A borreliose de Lyme é uma doença multi-sistémica com um espectro largo de sintomas clínicos. Borrelia burgdorferi, the agent of Lyme disease, possesses an elaborate genetic system, designated vmp-like sequence vls, on a 28-kb linear plasmid lp28-1. The presence of lp28-1 correlates with the high-infectivity phenotype in strains of B. burgdorferi, and homologous plasmids are present in low-passage, infectious strains of the Lyme. RecA is a key protein linking genetic recombination to DNA replication and repair in bacteria. Previous functional characterization of Borrelia burgdorferi RecA indicated that the protein is mainly involved in genetic recombination rather than DNA repair. Genetic recombination may play a role in B. burgdorferi persistence by generation of. Borrelia burgdorferi sensu lato complex encompasses several species of Borrelia that cause human infection. Borrelia burgdorferi sensu stricto hereafter referred to as B. burgdorferi is the etiologic agent of Lyme disease in North America, while B. burgdorferi, B. garinii and B. afzelii are all important in Eurasian disease.

Crystal Structure of Lyme Disease Variable Surface Antigen VlsE of Borrelia burgdorferi. VlsE is an outer surface lipoprotein ofBorrelia burgdorferi that undergoes antigenic variation through an elaborate gene conversion mechanism and is thought to play a major role in the immune response to the Lyme disease borellia. The crystal. The SERION ELISA classic Borrelia burgdorferi IgG and IgM tests are quantitative and qualitative immunoassays for the detection of human antibodies in serum, plasma or cerebrospinal fluid directed against Borrelia burgdorferi sensu lato. Intended Use The ZEUS ELISA Borrelia VlsE1/pepC10 IgG/IgM Test System is intended for the qualitative detection of IgG and IgM class antibodies to VlsE1 and pepC10 antigens from Borrelia burgdorferi in human serum. The assay is intended for testing serum samples from symptomatic patients or those suspected of having Lyme disease. Positive and. Three genetic markers of Borrelia burgdorferi have been associated with disseminated disease: the OspC type, the 16S-23S rRNA intergenic spacer type RST, and vlsE. Here, we modified previous methods so as to identify the three markers by PCR and restriction fragment length polymorphism in parallel, analyzed B. burgdorferi isolates from. Borrelia burgdorferi responds to a variety of host-derived factors and appropriately alters its gene expression for adaptation under different host-specific conditions. We previously showed that various levels of acetate, a short-chain fatty acid SCFA, altered the protein profile of B. burgdorferi.

Borrelia burgdorferi sensu stricto, diagnosed by serology. Ater a few weeks of infection, however, immunocompetent ﬁrming B. burgdorferi in all subsequent t er the in fection is cured. A variety of direct tests for the agent of tests include culture of Borrelia from skin or.
Variable Lipoprotein Surface-Exposed protein, or VlsE, is a lipoprotein on the surface of the Lyme Disease spirochete Borrelia burgdorferi, detectable during all its life stages. It can exist as many different isoforms. VlsE has variable regions VRs and invariable regions IRs. Some IRs are anchored in the outer membrane of the bacteria and. Borrelia burgdorferi sensu stricto B31 VlsE Protein. This is a recombinant Borrelia burgdorferi VlsE protein, fused to an MBP-tag and produced in E. coli >90% purity. Many parasites have evolved antigenic variation systems that alter their surface proteins in order to evade recognition by an immune response and subsequent death. The Vlp and Vsp proteins are antigenically distinct proteins, only one vlp or vsp gene is transcriptionally active at any one time. Switching between these genes is a. Borrelia is a genus of bacteria of the spirochete phylum. It causes Lyme disease, also called Lyme borreliosis, a zoonotic, vector-borne disease transmitted primarily by ticks and by lice, depending on the species of bacteria. The genus is named after French biologist Amédée Borrel 1867–1936, who first documented the distinction between a.

Details for: Borrelia / Lyme IgGVlsE ELISA. Borrelia / Lyme IgGVlsE ELISA. Aid in the diagnosis of acute and later stages of infections by Borrelia burgdorferi, the spirochete associated with Lyme disease. Lyme disease is a common vector-borne disease in the US caused by B burgdorferi, which is transmitted through the bite of infected ticks Ixodes spp. The tick-borne pathogen Borrelia burgdorferi is responsible for approximately 300,000 Lyme disease LD cases per year in the United States. Recent increases in the number of LD cases, in addition to the spread of the tick vector and a lack of a vaccine, highlight an urgent need for designing and developing an efficacious LD vaccine.

The diagnosis of Lyme disease will be reviewed here. Specific considerations regarding the diagnosis of Lyme arthritis and neurologic Lyme disease, as well as topic reviews that discuss the microbiology, epidemiology, immunopathogenesis, clinical manifestations, treatment, and prevention of Lyme disease, are presented elsewhere. Sera collected from dogs experimentally infected with Borrelia burgdorferi by tick inoculation were analyzed for an antibody response to each of the six invariable regions IRs; i.e., IR1 to IR6 of VlsE, the variable surface antigen of B. burgdorferi. Six synthetic peptides C1 to C6, which reproduced the six IR sequences were used as. Borrelia burgdorferi has numerous proteins that support an interaction with the extracellular components of the host cell. Different adhesions of Borrelia burgdorferi will be reviewed here to understand the characteristics of this bacterium and the disease it causes.

by Hannah Zucherman Introduction Lyme disease is caused by Borrelia burgdorferi, a member of the eubacterial phylum Spirochaetes. The bacterium possesses phenotypic characteristics of the genus Borrelia, appearing spiral or wavelike in appearance, with flagella organs of motility between the outer and inner membranes. Lyme disease was. Pathogens of Lyme borreliosis are bacteria from the group of Borrelia. Pathogenic genotypes are Borrelia garinii, B. afzelii, or B. burgdorferi sensu stricto. For detection of Lyme borreliosis, particularly immunogenic surface antigens such as OspC / OspA or DbpA, as well as VlsE and other proteins p39, p41, p58, p83 / 100 are used.
