The development of an IgG avidity Western blot with potential to differentiate patients with active Lyme borreliosis from those with past infection

Conclusion The Western blot/avidity Western blot with PLDA approach shows exciting potential for being able to predict disease stage in some patients with LB, which could improve patient management.

The aim of our study was to use geographical information systems (GIS) to select appropriate sampling sites of Ixodes ricinus ticks in central European habitat for further ecological studies of vector-borne pathogens (tick-borne encephalitis virus and Borrelia burgdorfe...

Lyme disease is caused by the spirochete Borrelia burgdorferi and is transmitted via the bite of an infected tick. B. burgdorferi enters the skin, disseminates via the bloodstream, and infects various distal tissues, leading to inflammatory sequelae, such as Lyme arthritis and Lyme carditis. B. burgdorferi linear plasmid 36 (lp36) is critical for mammalian infectivity; however, the full complement of genes on lp36 that contribute to this process remains unknown. Through a targeted mutagenesis screen of the genes on lp36, we identified a novel infectivity gene of unknown function, bbk13, which encodes an immunogenic, non-su...

Eisen, Goudarz MolaeiAbstractLyme disease is the most prevalent vector-borne disease in the United States. Ixodes scapularis, commonly referred to as the blacklegged tick, is the primary vector of Lyme disease spirochetes, Borrelia burgdorferi sensu lato (s.l.), in the eastern United States. Connecticut has pervasive populations of I. scapularis and remains a hotspot for Lyme disease. A primary aim of this study was to determine if passively collected...

In this study, we applied complementary in silico approaches to modeling how Anaplasma phagocytophilum infection modulates tick vector regulome. This proof-of-concept research provided support for the use of network analysis in the study of regulome response to infection, resulting in new information on tick-pathogen interactions and potential targets for developing interventions for the control of tick infestations and pathogen transmission. Deciphering the precise nature of circuits that shape the tick regulome in response to pathogen infection is an area of research that in the future will advance our knowledge of tick-...

Abstract Lyme disease, reffered to as Lyme borreliosis, is a tick-borne zoonotic disease caused by Borrelia burgdorferi spirochetes. Lyme arthritis, the most common, serious and harmful manifestation during the late stages of Lyme disease, is closely associated with the Borrelia burgdorferi basic membrane protein A (BmpA). Chemokines are also reported to have an important role in Lyme arthritis. Toll-like receptors (TLRs) recognize and bind to pathogen-associated molecules which are structurally conserved among microbes, to activate transcriptional events, including cytokine production, inflammation, and tissue da...

Unlike typical Fur proteins in which DNA binding represses gene expression, binding of BosR to the rpoS promoter directly activates rpoS transcription in B. burgdorferi. However, virtually nothing is known concerning potential structural fea...
