The aim of our study was to find a possible existence of various vaccination effects on the formation of antibodies against three individual Borrelia afzelii strains (dead cell suspension) isolated from a vector, potential vector and host of this spirochaete, which makes this experiment unique in the research of Lyme disease causative agents. Three strains of Borrelia afzelii were isolated from...

Diagnosis of active Lyme borreliosis (LB) remains a challenge in clinically ambiguous, serologically indeterminant, and polymerase chain reaction-negative patients. Lymphocyte transformation tests (LTTs) have been applied to detect specific cellular immune reactivity, but their clinical application has been severely hampered by the poorly defined Borrelia antigens and nonstandardized LTT format...

Ixodes ricinus horizontal movement within a humidity gradient and the influence of infection by Borrelia burgdorferi sensu lato (s.l.) on tick walking were investigated. Nymphs were placed within an arena containing a humidity gradient ranging from 45 to 95% relative humidity (RH). After 1 h of acclimation at 70% RH ticks were released so that they could either stay, or walk towards either the ...

Lyme disease Borreliae are highly dependent on the uptake of nutrients provided by their hosts. Our study describes the identification of a 36 kDa protein that functions as putative dicarboxylate-specific porin in the outer membrane of Lyme disease Borrelia. The protein was purified by hydroxyapatite chromatography from Borrelia burgdorferi B31 and designated as DipA, for dicarboxylate-specific...

AIMS Little is known about the effects of phytochemicals against Borrelia sp. causing Lyme disease. Current therapeutic approach to this disease is limited to antibiotics. This study examined the anti-borreliae efficacy of several plant-derived compounds and micronutrients. METHODS AND RESULTS We tested the efficacy of 15 phytochemicals and micronutrients against three morphological forms of ...

Many chronic inflammatory diseases are known to be caused by persistent bacterial or viral infections. A well-studied example is the tick-borne infection by the gram-negative spirochaetes of the genus Borrelia in humans and other mammals, causing severe symptoms of chronic inflammation and subsequent tissue damage (Lyme Disease), particularly in large joints and the central nervous system, but ...

Borrelia burgdorferi, the causative agent of Lyme disease, utilizes manganese (Mn) for its various metabolic needs. We hypothesized that blocking Mn transporter could be a possible approach to inhibit metabolic activity of this pathogen and eliminate the infection. We used a combination of in silico protein structure prediction together with molecular docking to target the Borrelia metal transp...

In this study we have developed a new Restriction-Fragment-Length-Polymorphism (RFLP) genotyping method for rapid detection and identification of Borrelia genospecies present as unique species or as co-infection in multiple specimens obtained simultaneously from 29 individual patients affected by early or late Lyme borreliosis (LB). The target of the RFLP-genotyping was the heterogeneous plasmi...

INTRODUCTION RLB (Reverse Line Blot Hybridization) is a molecular biology technique that might be used for Borrelia burgdorferi sensu lato (sl) DNA detection with genospecies specification. Among B. burgdorferi sl genospecies at least 7 are regarded as pathogenic in Europe. OBJECTIVE The aim of the study was to evaluate the frequency of different Borrelia genospecies DNA detection in Ixodes r...

In the literature, there are case reports suggesting that Borrelia burgdorferi infection may induce autoimmune diseases dependent on antinuclear antibodies (ANA). The present study was undertaken in order to verify this possibility in a prospective manner. The study group comprised 78 consecutive patients (51 women and 27 men, median age 41.5 years) referred to our Department for the serologic ...
