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 ...

Mini erythema migrans - A sign of early Lyme borreliosis [PDF]

, 2006
Background: An erythema migrans (EM) remaining smaller than 5 cm in diameter, called mini EM by us, has not been addressed in detail. Objective: To study the significance of the mini EM as a sign of Lyme borreliosis. Methods: Patients with suspected mini

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

Identification and functional characterisation of Complement Regulator Acquiring Surface Protein-1 of serum resistant Borrelia garinii OspA serotype 4 [PDF]

, 2010
Background: B. burgdorferi sensu lato (sl) is the etiological agent of Lyme borreliosis in humans. Spirochetes have adapted themselves to the human immune system in many distinct ways.

Prevalence and molecular identification of Borrelia spirochetes in Ixodes granulatus ticks collected from Rattus losea on Kinmen Island of Taiwan

Parasites & Vectors, 2012
Background Ixodes granulatus is widely distributed in various countries of Southeast Asia and Taiwan. Although this tick species is presumed to be the vector for the enzoonotic transmission of Borrelia spirochetes in the Taiwan area, the prevalence of ...

A Novel Genospecies of Borrelia burgdorferi Sensu Lato Associated with Cricetid Rodents in Brazil

Microorganisms, 2022
Borrelia burgdorferi sensu lato (Bbsl) spirochetes thrive in sylvatic transmission cycles infecting vertebrates and their ticks. Rodents and ticks of the genus Ixodes are important hosts of these spirochetes globally.

Identification of a third genomic group of Borrelia burgdorferi through signature nucleotide analysis and 16S rRNA sequence determination [PDF]

Journal of General Microbiology, 1992
As part of a continuing effort to assess genetic variation among isolates of Borrelia burgdorferi we have determined the 16S rRNA signature nucleotide makeup of two tick isolates from the USSR. Signature nucleotides were identified via reverse transcriptase primer extension sequencing of select regions of the 16S rRNA molecule.

Rhesus Brain Transcriptomic Landscape in an ex vivo Model of the Interaction of Live Borrelia Burgdorferi With Frontal Cortex Tissue Explants

Frontiers in Neuroscience, 2019
Lyme neuroborreliosis (LNB) is the most dangerous manifestation of Lyme disease caused by the spirochete Borrelia burgdorferi which can reach the central nervous system most commonly presenting with lymphocytic meningitis; however, the molecular basis ...

Use of CFSE staining of borreliae in studies on the interaction between borreliae and human neutrophils

BMC Microbiology, 2006
Background Species of the tick-transmitted spirochete group Borrelia burgdorferi sensu lato (B. burgdorferi) cause Lyme borreliosis. Acute borrelial infection of the skin has unusual characteristics with only a mild local inflammatory response suggesting
