The Centers for Disease Control and Prevention estimates that more than 300 000 new cases of Lyme disease occur each year in the United States and that 10% to 20% of these patients will remain symptomatic despite receiving appropriate antibiotic therapy. Many elements of the disease are poorly understood and have generated considerable controversy. This paper discusses the medical controversies related to posttreatment manifestations and their potential impact on infusion nurses.

The western European hedgehog () and the northern white-breasted hedgehog () are natural hosts of the tick , the vector of tick-borne pathogens such as the bacteria responsible for Lyme disease. The aim of this study was to identify these pathogens in ticks collected from hedgehogs in northwestern Poland and to assess their genetic diversity by molecular analysis of the detected pathogens based on the gene and the intergenic spacer. Among 101 hedgehogs examined, 737 ticks were found on 56 (55.

A novel panel of peptide for serological identification of Borrelia burgdoferi sensu stricto, Borrelia garinii and Borrelia afzelii was developed and assessed in this study. The diagnostic algorithm of the novel test was initially trained testing 10 US human sera including 3 early-stage and 3 late-stage Lyme disease positive sera, 2 sera positive for Babesia and 2 sera positive for Syphilis, all purchased from a private biorepository. Findings were then corroborated testing (a) 33 additional EU follow-up positive sera from seroconverted patients bitten by ticks that tested positive for B.

Host-pathogen interactions represent a dynamic evolutionary process, wherein both hosts and pathogens continuously develop complex mechanisms to outmaneuver each other. Borrelia burgdorferi, the Lyme disease pathogen, has evolved an intricate antigenic variation mechanism to evade the host immune response, enabling its dissemination, persistence, and pathogenicity. Despite the discovery of this mechanism over two decades ago, the precise processes, genetic elements, and proteins involved in this system remain largely unknown.

Background Objectives: This study was compared the Borrelia antibodies and chemokine ligand 13 (CXCL13) levels in cerebrospinal fluid (CSF) samples from cases diagnosed with relapsing-remitting multiple sclerosis (RRMS), radiologically isolated syndrome (RIS), and pseudotumour cerebri (PTC).
Methods: A total of 43 CSF samples were collected from patients diagnosed with RRMS, RIS and PTC. We prospectively investigated Borrelia IgG and IgM antibodies in the CSF samples of the cases by enzyme-linked immunosorbent assay (ELISA) and Western blot (WB) method, and CXCL13 levels by ELISA.

is a vector of several human pathogens in the United States, including the cause of Lyme disease, and Powassan virus (POWV), an emerging cause of severe encephalitis. Skin biopsies from tick bite sites are frequently collected and tested for the presence of spirochetes ( spp.), which remain elusive.
