Lyme borreliosis (LB) is a serious infectious disease of humans and some domestic animals in temperate regions of the Northern Hemisphere. It is caused by certain spirochetes in the Borrelia burgdorferi sensu lato (s.l.) species complex. The complex consists of 11 species (genospecies). Borrelia burgdorferi sensu stricto (s.s.), Borrelia garinii and Borrelia afzelii are the major agents of huma...

The possibility of vertical transmission of Borrelia burgdorferi sensu lato in Ixodes persulcatus Schulze, 1930 ticks was studied in the progeny of 20 females collected from the vegetation in an active focus of ixodid tick-borne borrelioses (ITBB) located in the Perm oblast, Russia, where Borrelia garinii and B. afzelii are circulating. The presence of Borrelia DNA was detected by the PCR metho...

From 2000 to 2004, ticks were collected by dragging a blanket in four habitat areas in The Netherlands: dunes, heather, forest, and a city park. Tick densities were calculated, and infection with Borrelia burgdorferi and Anaplasma and Ehrlichia species was investigated by reverse line blot analysis. The lowest tick density was observed in the heather area (1 to 8/100 m2). In the oak forest and ...

Several infectious agents may cause arthritis or arthropathy. For example, infection with Borrelia burgdorferi, the etiologic agent of Lyme disease, may in the late phase manifest as arthropathy. Infections with Campylobacter, Salmonella, or Yersinia may result in a postinfectious reactive arthritis. Acute infection with parvovirus B19 (B19V) may likewise initiate transient or chronic arthropat...

Data presented in this study focuses on the presence of anti-Borrelia antibodies in small mammals from Eastern Slovakia during 2000-2003. The total seropositivity observed was 18.78% in rodents. Amongst all species, the total seroprevalence in Apodemus flavicolis was the highest (20.87%), followed by Apodemus agrarius (19.58%) and Clethrionomys glareolus (11.11%). However, the prevalence in Apo...

INTRODUCTION The symptoms of Brazilian borreliosis resemble the clinical manifestations of Lyme disease (LD). However, there are differences between the two in terms of epidemiological and laboratory findings. Primers usually employed to diagnose LD have failed to detect Borrelia strains in Brazil. OBJECTIVE We aimed to identify the Brazilian Borrelia using a conserved gene that synthesizes t...

The tick Ixodes ricinus is responsible for the transmission and maintenance of a wide variety of pathogenic organisms in the Northern Hemisphere, among which Lyme disease represents a major threat to humans. Despite numerous studies, the epidemiology of the different bacterial species responsible for this disease remains unclear. Recent evidence for a sex-biased genetic structure of its Europea...

Ixodes persulcatus (n = 125) and Dermacentor reticulatus (n = 84) ticks from Western Siberia, Russia, were tested for infection with Borrelia, Anaplasma/Ehrlichia, Bartonella, and Babesia spp. by using nested polymerase chain reaction assays with subsequent sequencing. I. persulcatus ticks were infected with Borrelia burgdorferi sensu lato (37.6% +/- 4.3% [standard deviation]), Anaplasma phagoc...

Borrelia burgdorferi, the causative agent of Lyme disease, was isolated from the liver of a passerine bird, Catharus fuscescens (veery), and from larval Ixodes dammini (tick) feeding on Pheucticus ludovicianus (rose-breasted grosbeak) and Geothlypis trichas (common yellowthroat). In indirect immunofluorescence antibody tests, isolates reacted with polyclonal and monoclonal (H5332) antibodies. S...

: Pseudolymphomatous infiltrates in Borrelia infection of the skin most commonly manifest with dense B-cell infiltrates and plasma cells. Cutaneous infiltrates of B-cell chronic lymphocytic leukemia (B-CLL) may accumulate at sites of infection, including Borrelia infection. We report an unusual constellation in a patient with synchronously diagnosed B-CLL and Borrelia infection of skin presenti...
