Seroprotective groups among isolates of Borrelia burgdorferi [PDF]

Infection and Immunity, 1993
We demonstrated that different seroprotective groups exist among isolates of Borrelia burgdorferi and Borrelia garinii. The major group was composed of isolates 297, B31, S-1-10, MMTI, IPT, and ATCC 35211 and 21 isolates obtained from California, Illinois, New York, Texas, and Wisconsin. A second group was composed of European isolates PBi and G25.

Identification of different Borrelia burgdorferi genomic groups from Scottish ticks [PDF]

Molecular Pathology, 2000
To characterise 12 Borrelia burgdorferi sensu lato isolates cultured from ticks collected in the Highlands of Scotland.Three molecular methods were used: an outer surface membrane protein A (OSP A) gene polymerase chain reaction (PCR) designed to give different molecular weight products with different genomic groups, randomly amplified polymorphic DNA (

Individualisation of two new genomic groups among AmericanBorrelia burgdorferisensu lato strains [PDF]

FEMS Microbiology Letters, 1994
We developed a quick typing method for Borrelia burgdorferi sensu lato strains using a fla gene-based PCR assay, followed by dot blot hybridization with non-radioactive species-specific probes. Thirty-six out of 46 strains belonged to one of the four described species (B. burgdorferi sensu stricto n = 11, B. garinii n = 11, B.

Delineation of Borrelia burgdorferi Sensu Stricto, Borrelia garinii sp. nov., and Group VS461 Associated with Lyme Borreliosis [PDF]

International Journal of Systematic Bacteriology, 1992
We studied 48 Borrelia isolates that were associated with Lyme borreliosis or were isolated from ticks and identified three DNA relatedness groups by using the S1 nuclease method. The three DNA groups (genospecies) were associated with specific rRNA gene restriction patterns, protein electrophoresis patterns, and patterns of reactivity with murine ...

Borrelia valaisiana resist complement-mediated killing independently of the recruitment of immune regulators and inactivation of complement components [PDF]

, 2013
Spirochetes belonging to the Borrelia (B.) burgdorferi sensu lato complex differ in their resistance to complement-mediated killing, particularly in regard to human serum.

BIOLOGICAL ASPECTS OF LYME DISEASE SPIROCHETES: UNIQUE BACTERIA OF THE BORRELIA BURGDORFERI SPECIES GROUP [PDF]

Biomedical Papers, 2007
Borrelia burgdorferi sensu lato is a group of at least twelve closely related species some of which are responsible for Lyme disease, the most frequent zoonosis in Europe and the USA. Many of the biological features of Borrelia are unique in prokaryotes and very interesting not only from the medical viewpoint but also from the view of molecular biology.

Detection of Borrelia afzelii, Borrelia burgdorferi sensu stricto, Borrelia garinii and group VS116 by PCR in skin biopsies of patients with erythema migrans and acrodermatitis chronica atrophicans [PDF]

Clinical Microbiology and Infection, 1997
OBJECTIVE: To evaluate the diagnostic performance of two polymerase chain reaction (PCR) procedures using skin biopsies of 20 erythema migrans (EM) and 24 acrodermatitis chronica atrophicans (ACA) patients. METHODS: One assay amplified a fragment of the outer surface protein (Osp) A gene. The second method amplified the spacer region between the 5S and

Multicentric Study of Seroprevalence of Borrelia Burgdorferi and Anaplasma Phagocytophila in High-Risk Groups in Regions of Central and Southern Italy [PDF]

International Journal of Immunopathology and Pharmacology, 2004
The aim of this study was to evaluate the seroprevalence of B. burgdorferi and A. phagocytophila in populations of workers from 4 Italian regions, known to be exposed to tick bites. A total of 712 serum samples collected were divided as follows: 387 samples were obtained from workers at risk for tick bites and 325 from individuals that were not ...

Possible effect of mutations on serological detection of Borrelia burgdorferi sensu stricto ospC major groups: An in-silico study

PLOS ONE, 2023
The outer surface protein C (OspC) of the agent of Lyme disease, Borrelia burgdorferi sensu stricto, is a major lipoprotein surface-expressed during early-phase human infections. Antibodies to OspC are used in serological diagnoses. This study explored the hypothesis that serological test sensitivity decreases as genetic similarity of ospC major groups

The Borrelia afzelii outer membrane protein BAPKO_0422 binds human Factor-H and is predicted to form a membrane-spanning beta-barrel [PDF]

, 2015
The deep evolutionary history of the Spirochetes places their branch point early in the evolution of the diderms, before the divergence of the present day Proteobacteria.
