Over the past ten years there has been a significant rise in the number of people who present to emergency departments with Lyme disease. Although some patients remain asymptomatic many present with a rash around a previous tick bite and others may present with a range of debilitating symptoms that can be problematic if left untreated. Due to the growing prevalence of Lyme disease in the UK and the US this article gives an overview of the vector-borne condition and provides emergency nurses with information about the pathophysiology, prevention, presenting signs and symptoms and management...

The blacklegged tick, Ixodes scapularis Say (Acari: Ixodidae), is an economically important tick that affects veterinary and public health, but it can be difficult to collect in Oklahoma. The primary goal of this research was to examine the diel activity of each species to help improve collection methods for future field research and test field-collected I. scapularis for endemic and nonendemic tick-borne bacterial genera in the southern Great Plains region. Questing behavior was observed using caged bioassays over 24-h periods throughout fall and spring, and field collections were conducted throughout the afternoon and evening in different locations across Oklahoma...

Anti-Borrelia antibodies in the cerebrospinal fluid (CSF) are required for definite diagnosis of Lyme neuroborreliosis (LNB). However, children often present with early LNB, and antibody production in the CSF may not be demonstrated. Recent studies have suggested the chemokine CXCL13 to be an early marker for LNB. The aim of the study was to evaluate CXCL13 for laboratory diagnosis in pediatric LNB patients and to evaluate the association with pleocytosis in CSF, clinical features, and recovery. CSF samples were collected from LNB patients, classified as definite LNB (n = 44) or possible LNB (n = 22), and controls classified as non-LNB (n = 102) or other specific diagnoses (n = 23)...

BACKGROUND: Small mammals are essential in the enzootic cycle of many tick-borne pathogens (TBP). To understand their contribution to the genetic diversity of Borrelia afzelii, the most prevalent TBP in questing Ixodes ricinus, we compared the genetic variants of B. afzelii at three distinct genetic loci. We chose two plasmid loci, dbpA and ospC, and a chromosomal one, IGS. RESULTS: While the larvae that fed on shrews (Sorex sp.) tested negative for B. afzelii, those fed on bank voles (Myodes glareolus) and wood mice (Apodemus sylvaticus) showed high infection prevalences of 0...

Lyme disease is the most common vector-borne illness in North America, with the majority of cases occurring in the Northeast and upper Midwest. Lyme arthritis is the most prevalent manifestation of late-stage Lyme disease. Lyme arthritis typically presents as a monoarthritis or oligoarthritis in large joints such as the knee. Accompanying positive 2-tier Lyme serologies or polymerase chain reaction from synovial fluid/tissue is considered diagnostic for patients from an endemic area. The mainstay of initial treatment is a prolonged course of oral antibiotics...

The recent proposal of splitting the genus Borrelia into two genera in the newly formed family of Borreliaceae, i. e. Borrelia and Borreliella has motivated us to reflect upon how these organisms has been characterized and differentiated. This article therefore aims to take a closer look on the biology and virulence attributes of the two suggested genera, i. e. those causing Lyme borreliosis and relapsing fever borreliosis. Both genera have much in common with similar infection biological features. They are both characterized as bacterial zoonoses, transmitted by hematophagous arthropods with almost identical microbiological appearance...

Importance: Multiple erythema migrans (MEM) has been suggested as a risk factor for unfavorable antibiotic treatment outcome compared with solitary erythema migrans (EM). However, no direct comparison of early Lyme borreliosis manifested as MEM with solitary EM has been undertaken. Objective: To investigate the potential differences in clinical course and treatment outcome between MEM and solitary EM. Design, Setting, and Participants: This prospective cohort study was conducted from June 1, 2010, to October 31, 2015, at the University Medical Center Ljubljana, Slovenia...

Lyme disease ( Borrelia burgdorferi infection) is increasingly recognized as a significant source of morbidity worldwide. Here, we show that blood plasmablasts and CD27- memory B cells are elevated in untreated Lyme disease, with higher plasmablast levels associated with more rapid resolution of clinical symptoms. Stronger serum reactivity to surface proteins and peptides from B. burgdorferi was also associated with faster resolution of clinical symptoms. Through molecular identifier-enabled antibody heavy-chain sequencing of bulk B cells and single-cell paired-chain antibody sequencing of blood plasmablasts, we characterized immunoglobulin gene usage patterns specific to B...

BACKGROUND: Infection with Borrelia burgdorferi sensu lato complex (B. b. sl) spirochetes can cause Lyme borreliosis, manifesting as localized infection (e.g. erythema migrans) or disseminated disease (e.g. Lyme neuroborreliosis). Generally, patients with disseminated Lyme borreliosis will produce an antibody response several weeks post-infection. So far, no case of neuroborreliosis has been described with persistently negative serology one month after infection. CASE PRESENTATION: We present a patient with a history of Mantle cell lymphoma and treatment with R-CHOP (rituximab, doxorubicine, vincristine, cyclofosfamide, prednisone), with a meningo-encephalitis, who was treated for a suspected lymphoma relapse...

Lyme borreliosis (LB) is the most common tick-borne infectious disease in North America, and it was designated as a national notifiable infectious disease in Korea in December 2010. While no cases in Jeju-do were recorded from 2012 to 2016, a recent survey reported that the seroprevalence of Borrelia burgdorferi using enzyme-linked immunosorbent assays in horses in Jeju-do was 19.0% (95% confidence interval, 12.0 to 28.3%). This fact suggests that horses may be a potential reservoir of LB in Jeju-do and that individuals in close contact with horses may be a high-risk group...

Lyme disease (LD) is a multisystemic inflammatory disease caused by pathogenic spirochetes, belonging to the genospecies complex Borrelia burgdorferi sensu lato (B.b.s.l.). Around the world, distinct species of Ixodes tick vectors transmit different species of Borrelia. Despite the rising recognition and occurrence of tick-borne disease in Latin America, serology has proven to be inconclusive in detecting suspected LD cases. Recently, new B.b.s.l. strains or new related species have been described in Brazil, Uruguay, and Chile...

Knowing the frequency of positive Lyme disease serology in children without signs of infection facilitates test interpretation. Of 315 asymptomatic children from Lyme disease endemic regions, 32 had positive or equivocal C6 enzyme linked immunoassays, but only 5 had positive IgG or IgM supplemental immunoblots (1.6%, 95% confidence interval 0.7-3.7%).

Northeastern China is a region of high tick abundance, multiple tick-borne pathogens and likely human infections. The spectrum of diseases caused by tick-borne pathogens has not been objectively evaluated in this region for clinical management and for comparison with other regions globally where tick-transmitted diseases are common. Based on clinical symptoms, PCR, indirect immunofluorescent assay and (or) blood smear, we identified and described tick-borne diseases from patients with recent tick bite seen at Mudanjiang Forestry Central Hospital...

Dogs can carry and share zoonotic pathogens with humans. This problem is understudied in different parts of the world, including Jordan. This study determined the prevalence of Anaplasma phagocytophilum, Ehrlichia canis, Dirofilaria immitis, and Borrelia burgdorferi using the SNAP 4Dx Plus test and spotted fever group rickettsiae (SFGR) using enzyme immunoassay IgG test in different types of dogs (farm/breeding, police, and stray) in Jordan. The results showed a very high seroprevalence (87%) of SFGR in dogs all over Jordan...

The distribution, abundance and seasonal activity of vector species, such as ticks and mosquitoes, are key determinants of vector-borne disease risk, and are strongly influenced by abiotic and habitat conditions. Despite the numerous species of tick vectors in the heavily populated North American West Coast, all but Ixodes pacificus, the primary vector of the Lyme disease spirochete, is poorly characterized with regard to seasonal activity patterns and fine scale drivers of distribution and abundance, particularly in heavily populated regions of southern California...

A 45-year-old man was presented with 3 weeks of fever, chills, headache, myalgia and sweats after returning from a camping trip. He had multiple erythematous, blanching, non-target lesions on back and lower abdomen and oral pseudomembrane. He was empirically started on doxycycline for presumed Lyme disease and hydration for management of acute renal failure. Next day, he was started on vancomycin for worsening rash and coverage of methicillin-resistant Staphylococcus aureus skin infection and fluconazole for possible thrush and tested for HIV, syphilis, tick-borne diseases, arboviral panel, Epstein-Barr virus, rapid plasma reagin and rheumatoid factor...
