Prevalence of Borrelia burgdorferi sensu lato infection in the Czech Republic.

Introduction: Lyme borreliosis (LB), an infection caused by Borrelia burgdorferi sensu lato (Bbsl), is the most common tick-borne disease in Europe. To further characterize the LB burden in the Czech Republic, we conducted a seroprevalence study and estimated the incidence of symptomatic Bbsl infections.

Methods: Anti-Bbsl IgM and IgG antibodies were detected in sera collected from the adult population in 2011 -2012 by enzyme-linked immunosorbent assay and immunoblot tests at the National Reference Laboratory.

First isolation of Borrelia lusitaniae DNA from green lizards (Lacerta viridis) and Ixodes ricinus ticks in the Czech Republic.

This study aimed to reveal whether green lizards (Lacerta viridis), common hosts of tick larvae and nymphs, might be involved in the transmission cycle of Borrelia burgdorferi sensu lato in the Czech Republic. Green lizards were sampled in two areas at the Tiché Údolí Nature Reserve (site A: 50.1482 N, 14.

Metamorphoses of Lyme disease spirochetes: phenomenon of Borrelia persisters.

The survival of spirochetes from the Borrelia burgdorferi (sensu lato) complex in a hostile environment is achieved by the regulation of differential gene expression in response to changes in temperature, salts, nutrient content, acidity fluctuation, multiple host or vector dependent factors, and leads to the formation of dormant subpopulations of cells. From the other side, alterations in the level of gene expression in response to antibiotic pressure leads to the establishment of a persisters subpopulation. Both subpopulations represent the cells in different physiological states.

[Guideline for the diagnosis and treatment of Lyme borreliosis].

The national guideline aims to highlight the latest knowledge about clinical manifestations of the infection, to summarize the diagnostic algorithm and to recommend the appropriate antibiotic therapy with respect to evidence-based medicine. The recommendations are consistent with most European guidelines as well as those published by the IDSA. The guideline provides the most recent information on the epidemiology, etiology and pathogenesis of Lyme borreliosis, dermatological, neurological and musculoskeletal involvement, the appropriate diagnostic procedure and prevention.

A serological study of antibodies to Anaplasma phagocytophilum and Borrelia burgdorferi sensu lato in the sera of healthy individuals collected two decades apart.

Sera collected from healthy individuals from the general population in the Czech Republic during repeated cross-sectional surveys were analyzed. Samples collected in the same six districts in two time periods, 1978-1989 and 2001, were compared. The study subjects were divided into six age categories between 10 and 59 years.

Detection of Borrelia burgdorferi sensu lato and Anaplasma phagocytophilum in questing ticks Ixodes ricinus from the Czech Republic.

The aim of the present study is to compare the prevalence of Borrelia burgdorferi sensu lato (s.l.) and Anaplasma phagocytophilum in questing ticks by using molecular methods from spring to autumn 2007.

Detection of Anaplasma phagocytophilum and Borrelia burgdorferi sensu lato in dogs in the Czech Republic.

The aim of this study is to present molecular, serologic, and clinical findings for dogs that were naturally infected with Anaplasma phagocytophilum or Borrelia burgdorferi sensu lato (s. l.) in the Czech Republic.
