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.

Spotted fever group rickettsiae or Borrelia burgdorferi in Ixodes cookei (Ixodidae) in Connecticut [PDF]

Journal of Clinical Microbiology, 1991
Immatures and females of Ixodes cookei, a hard-bodied tick, were collected from woodchucks and other mammals in the northeastern United States and examined for spotted fever group rickettsiae and Borrelia burgdorferi. Of the 93 nymphs analyzed by a hemolymph test, 4 (4.3%) harbored rickettsiae. Six (15%) of 40 females were also infected.

Seropositivity of Borrelia burgdorferi in Risky Groups in Van Region, Turkey

Mikrobiyoloji Bulteni, 2015
Lyme borreliosis, which is more prevalent in the northern hemisphere, is the most common tick-borne contagious disease among people living in the North America and Europe. The causative agent of Lyme borreliosis, Borrelia burgdorferi, is transmitted by the bites of ticks of the genus Ixodes. In Turkey, the seroprevalence of Lyme disease is increased in

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

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.

Abilities of OspA proteins from different seroprotective groups of Borrelia burgdorferi to protect hamsters from infection [PDF]

Infection and Immunity, 1995
The ability of vaccination with recombinant OspA from six seroprotective groups of Borrelia burgdorferi sensu lato to induce protection against infection with homologous and other Lyme spirochetes was examined in hamsters. Antisera generated against the OspA proteins of B.

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

Species-specific identification of and distinction between Borrelia burgdorferi genomic groups by using 16S rRNA-directed oligonucleotide probes [PDF]

Journal of Clinical Microbiology, 1992
Examination of a number of previously published aligned Borrelia 16S rRNA sequences revealed the presence of regions which could serve as oligonucleotide probe targets for both species-specific identification of Borrelia burgdorferi and distinction between genomic groups. Total cellular RNA isolated from Borrelia cultures was used in slot blot analysis.
