Human babesiosis co-infected with Lyme disease in a young patient is an important condition. Here, we describe a case of a 39-year-old male patient with concurrent babesiosis and Lyme disease. Co-infections of tick borne diseases are often difficult to diagnose and underreported, and resulting in significant morbidity and mortality to patients. While co-infections have been infrequently described, it is of paramount importance that clinicians should be able to diagnose early and treat them effectively according to the patient geographical area and history of tick bite...

We examined whether pet ownership increased the risk for tick encounters and tickborne disease among residents of three Lyme disease-endemic states as a nested cohort within a randomized controlled trial. Information about pet ownership, use of tick control for pets, property characteristics, tick encounters and human tickborne disease were captured through surveys, and associations were assessed using univariate and multivariable analyses. Pet-owning households had 1.83 times the risk (95% CI = 1.53, 2.20) of finding ticks crawling on and 1...

Experimental Lyme arthritis provides a mouse model for exploring the development of pathology following infection of C3H mice with Borrelia burgdorferi. Infected mice develop a reliable inflammatory arthritis of the ankle joint with severity that typically peaks around two to three weeks post-infection and then undergoes spontaneous resolution. This makes experimental Lyme arthritis an excellent model for investigating the mechanisms that drive both the development and resolution phases of inflammatory disease...

Lyme disease is a zoonosis caused by infection with Borrelia burgdorferi (Bb). A great amount of research has attempted to elucidate the mechanisms by which Bb causes inflammation and chronic symptomatology in some patients. Patients often seek unconventional treatments that lack scientific evidence, as medical care is unable to effectively explain and treat their illness. Bb-DNA can persist for long periods of time in some individuals, even after antibiotic therapy. Herein, scientific rationale is presented for a new therapeutic approach against remaining bacterial DNA, and/or increasing the ability of human macrophages to remove extracellular Bb DNA...

Knowledge of the transcriptional responses of vector-borne pathogens at the vector-pathogen interface is critical for understanding disease transmission. Borrelia (Borreliella) burgdorferi, the causative agent of Lyme disease in the United States, is transmitted by the bite of infected Ixodes sp. ticks. It is known that B. burgdorferi has altered patterns of gene expression during tick acquisition, persistence and transmission. Recently, we and others have discovered in vitro expression of RNAs found internal, overlapping, and antisense to annotated open reading frames in the B...

The term "chronic Lyme disease" is used by some health care providers as a diagnosis for various constitutional, musculoskeletal, and neuropsychiatric symptoms (1,2). Patients with a diagnosis of chronic Lyme disease have been provided a wide range of medications as treatment, including long courses of intravenous (IV) antibiotics (3,4). Studies have not shown that such treatments lead to substantial long-term improvement for patients, and they can be harmful (1,5). This report describes cases of septic shock, osteomyelitis, Clostridium difficile colitis, and paraspinal abscess resulting from treatments for chronic Lyme disease...

Lyme Borreliosis is a common tick-borne disease of the northern hemisphere caused by the spirochaetes of the Borrelia burgdorferi sensu lato (B. burgdorferi s. l.) complex. It results in multi-organ disease with arthritic, cardiac, neurological and dermatological manifestations. In the last twenty-five years there have been over 500 reports of an Australian Lyme-like syndrome in the scientific literature. However, the diagnoses of Lyme Borreliosis made in these cases have been primarily by clinical presentation and laboratory results of tentative reliability and the true cause of these illnesses remains unknown...

In order to study the antibody seroprevalence of the causal agent of Lyme borreliosis, Borrelia burgdorferi sensu lato (s.l.), and the history of tick bites at a geographical distribution limit of Ixodes ricinus, we compared healthy blood donors in geographically extreme regions: the borreliosis-endemic Vestfold County (59°N) and the region of northern Norway. Blood samples were screened using IgG/VlsE ELISA, and positive/borderline samples were confirmed using C6 ELISA and immunoblot assays. Also, donors completed a questionnaire consisting of several items including the places they have lived, and whether they owned any pets...

Man-made barriers are well known for their effects on ecosystems. Habitat fragmentation, for instance, is a recognised consequence of modern-day infrastructure. The aim of the present study was to investigate the diversity and abundance of tick species, as well as the risks of acquiring tick-borne infections in habitats adjacent to a freeway. Therefore, ixodid ticks were collected from the vegetation at two-week intervals (in the main tick season, from March to June) in eight habitats of different types (forest, grove, grassland) along both sides of a freeway...

Real-time PCR assays have recently been implemented in diagnostics for many bacterial pathogens, allowing rapid and accurate detection, which ultimately results in improved clinical intervention. Here, we describe a sensitive method of detection for three common tick-borne pathogens Borrelia burgdorferi, Anaplasma phagocytophilum, and Babesia microti since coinfections with these pathogens have started occurring with increasing frequency over the last several years in both North America and Europe. A shared geographic region, the same tick vectors, and similar transmission cycle all favor simultaneous transmission of these three tick-borne pathogens...

BACKGROUND: A number of studies have assessed possible climate change impacts on the Lyme disease vector, Ixodes scapularis. However, most have used surface air temperature from only one climate model simulation and/or one emission scenario, representing only one possible climate future. OBJECTIVES: We quantified effects of different Representative Concentration Pathway (RCP) and climate model outputs on the projected future changes in the basic reproduction number () of I...

The black-legged tick, Ixodes scapularis Say, is the primary vector of Borrelia burgdorferi, a spirochete that causes Lyme disease, in eastern North America. Lyme disease risk has generally been considered to be focused in the Northeast and the northern Midwest in the United States, yet the distribution of the vector extends considerably more broadly. A recent analysis of the distribution of the species using ecological niche modeling approaches painted an odd biogeographic picture, in which the species is distributed in a "rimming" distribution across the northern Midwest and Northeast, and along the Atlantic and Gulf coasts of the eastern United States, but not broadly in the interior of eastern North America...

The ferric uptake regulator (Fur) family of DNA-binding proteins represses and/or activates gene transcription via divalent metal ion-dependent signal sensing. The Borrelia burgdorferi Fur homologue, also known as Borrelia oxidative stress regulator (BosR), promotes spirochetal adaptation to the mammalian host by directly repressing the lipoproteins required for tick colonization and indirectly activating those required for establishing infection in the mammal. Here, we examined whether the DNA-binding activity of BosR was regulated by any of the four most prevalent transition metal ions in B...

BACKGROUND: Borrelia mayonii is currently the latest species belonging to the Borrelia burgdorferi (sensu lato) complex to be discovered. Interestingly it is involved in human pathology causing a high fever. We looked for its presence in post- tick bite febrile patients as well as in Ixodes ricinus ticks in an endemic area of France. RESULTS: After ensuring that our molecular technics correctly detected B. mayonii, 575 patients and 3,122 Ixodes ricinus nymphs were tested...

S. Typhimurium can induce both humoral and cell-mediated responses when establishing itself in the host. These responses are primarily stimulated against the lipopolysaccharide and major outer membrane (OM) proteins. OmpA is one of these major OM proteins. It comprises a N-terminal eight-stranded β-barrel trans membrane domain and a C-terminal domain (OmpA(CTD) ). The OmpA(CTD) and its homologs are believed to bind to peptidoglycan (PG) within the periplasm, maintaining bacterial osmotic homeostasis and modulating the permeability and integrity of the OM...

We aimed to detect DNA of Borrelia burgdorferi in whole blood and serum samples of patients with clinical symptoms and epidemiology compatible with Brazilian Lyme-like disease. Four patients with positive epidemiological histories were recruited for the study. Blood samples were collected, screened by serologic testing by ELISA and Western blotting and molecular identification of B. burgdorferi by amplifying a fragment of the conserved gene that synthesizes the hook flagellar flgE. The results showed positive serology and for the first time, the presence of B...

In early Lyme disease (LD), serological testing is insensitive and seroreactivity may reflect active or past infection. Here, we evaluated a novel assay for the direct detection of three species of Borrelia spirochetes in whole blood. The T2 Magnetic Resonance (T2MR®) assay platform was used to amplify Borrelia DNA released from intact spirochetes and to detect amplicon. Analytical sensitivity was determined from blood spiked with known concentrations of spirochetes, and the assay's limit of detection was found to be in the single cell/mL range: 5 cells/mL for B...

Nervous system involvement occurs in up to 15% of patients with Lyme disease, most commonly manifested as cranial neuropathy, lymphocytic meningitis, and or radiculoneuritis. We describe a patient with subacute radiculopoliomyelitis-myelitis matching the selective involvement of the anterior horns and roots of the cervical spinal cord seen on MRI and on electrodiagnostic studies. We demonstrate positive CSF Lyme antibodies and document a near-complete recovery with antibiotics. This case highlights the importance of recognizing an atypical presentation of Lyme disease in the setting of initial radiculitis and or myelitis, particularly given the potential for favorable outcomes with appropriate treatment...

BACKGROUND: In previous studies, human oligodendrocytes were demonstrated to undergo apoptosis in the presence of Borrelia burgdorferi under an inflammatory milieu. Subsequently, we determined that the MEK/ERK pathway played a significant role in triggering downstream inflammation as well as apoptosis. However, the identity of receptors triggered by exposure to B. burgdorferi and initiating signaling events was unknown. METHODS: In this study, we explored the role of several TLR and EGFR/FGFR/PDGFR tyrosine kinase pathways in inducing inflammation in the presence of B...
