Sera collected from healthy individuals from the general population in the Czech Republic during repeated cross-sectional surveys were analyzed. Samples collected in the same six districts in two time periods, 1978-1989 and 2001, were compared. The study subjects were divided into six age categories between 10 and 59 years. Overall, 434 samples from 1978-1989 and 270 samples from 2001 were screened for Anaplasma phagocytophilum (AP) and Borrelia burgdorferi sensu lato (BB). The anti-AP positivity rates were 13...

We conducted an investigation of Borrelia miyamotoi infections in humans and ticks in northeastern China. Of 984 patients reporting recent tick bites, 14 (1.4%) were found to be infected with B. miyamotoi by PCR and genomic sequencing. The 14 patients had nonspecific febrile manifestations, including fever, headache, anorexia, asthenia, and arthralgia. Rash, eschar, and regional lymphadenopathy were each observed in 1 patient. Four (28.6%) patients were hospitalized because of severe disease. B. miyamotoi was detected in 3...

The dilution effect in the zoonotic disease transmission cycle theorizes that an increased diversity of host species will alter transmission dynamics, result in a decrease in pathogen prevalence, and potentially lower human disease incidence. The interrelationship of Borrelia burgdorferi (Johnson, Schmid, Hyde, Steigerwalt, and Brenner) (Spirochaetales: Spirochaetaceae), the etiological agent of Lyme disease (LD), and its primary vector, blacklegged ticks (Ixodes scapularis Say) (Acari: Ixodidae), is a commonly used example of the dilution effect, suggesting that an increased diversity of host species will be found in large, undisturbed forested tracts and lower diversity in fragmented forests...

Background: Lyme encephalopathy, characterized by non-specific neurobehavioral symptoms including mild cognitive difficulties, may occur in patients with systemic Lyme disease and is often mistakenly attributed to CNS infection. Identical symptoms occur in innumerable other inflammatory states and may reflect the effect of systemic immune mediators on the CNS. Methods: Multiplex immunoassays were used to characterize the inflammatory profile in serum and CSF from Lyme and non-Lyme patients with a range of symptoms to determine if there are specific markers of active CNS infection (neuroborreliosis), or systemic inflammatory mediators associated with neurobehavioral syndromes...

In the United States, the blacklegged tick, Ixodes scapularis, is a vector of seven human pathogens, including those causing Lyme disease, anaplasmosis, babesiosis, Borrelia miyamotoi disease, Powassan virus disease, and ehrlichiosis associated with Ehrlichia muris eauclarensis. In addition to an accelerated rate of discovery of I. scapularis-borne pathogens over the past two decades, the geographic range of the tick, and incidence and range of I. scapularis-borne disease cases, have increased. Despite knowledge of when and where humans are most at risk of exposure to infected ticks, control of I...

Central Queensland (CQ) is a large and isolated, low population density, remote tropical region of Australia with a varied environment. The region has a diverse fauna and several species of ticks that feed upon that fauna. This study examined 518 individual ticks: 177 Rhipicephalus sanguineus (brown dog tick), 123 Haemaphysalis bancrofti (wallaby tick), 102 Rhipicephalus australis (Australian cattle tick), 47 Amblyomma triguttatum (ornate kangaroo tick), 57 Ixodes holocyclus (paralysis tick), 9 Bothriocroton tachyglossi (CQ short-beaked echidna tick), and 3 Ornithodoros capensis (seabird soft tick)...

Chiropteran mammals worldwide harbour trypanosomes (Euglenozoa: Kinetoplastea: Trypanosomatida) of the subgenus 'Schizotrypanum' in the classical sense. Latterly, these trypanosomes have been referred to as members of the 'Trypanosoma cruzi clade' as their phylogenetic relationships, structure and life cycle conform to T. cruzi, parasitising various terrestrial mammals as well as humans in Latin America. Little is known, however, about the trypanosome species in Asian bats. During a survey on Borrelia spp. in the Eastern bent-winged bat (Miniopterus fuliginosus) living in a cave in Wakayama Prefecture, Japan, incidental proliferation of trypanosomes was detected in two of 94 haemocultures...

T cells predominate the immune responses in the synovial fluid of patients with persistent Lyme arthritis; however, their role in Lyme disease remains poorly defined. Using a murine model of persistent Lyme arthritis, we observed that bystander activation of CD4+ and CD8+ T cells leads to arthritis-promoting IFN-γ, similar to the inflammatory environment seen in the synovial tissue of patients with posttreatment Lyme disease. TCR transgenic mice containing monoclonal specificity toward non-Borrelia epitopes confirmed that bystander T cell activation was responsible for disease development...

A relapsing fever group Borrelia sp. was detected from the blood of wild deer (Cervus nippon) in Japan. The Borrelia sp. was distributed nationwide among deer with an overall prevalence of 26% in blood samples. The prevalence of infection was significantly higher in fawns (48.4%) compared to adult deer (23.6%). Sequencing analysis reveals that this Borrelia sp. belongs to the hard tick-borne relapsing fever borreliae, and that it forms a single lineage based on sequences of the flagellin and glycerophosphodiester phosphodiesterase genes...

In Autoimmune disease a combination of infection, genetic and environmental factors causes an autoimmune response to the thyroid gland (characterized by lymphocytic infiltrations), thyroid stimulating hormone receptor (TSHR) and different thyroid antigens. Graves' and Hashimoto disease are autoimmune disorders with genetic predisposition. CD40 that stimulates the proliferation and differentiation of lymphocytes is an essential immunomodulatory component for follicular cells in the thyroid and the cell that present the antigen...

Some patients with a history of Borrelia burgdorferi infection develop a chronic symptomatology characterized by cognitive deficits, fatigue, and pain, despite antibiotic treatment. The pathogenic mechanism that underlines this condition, referred to as post-treatment Lyme disease syndrome (PTLDS), is currently unknown. A debate exists about whether PTLDS is due to persistent infection or to post-infectious damages in the immune system and the nervous system. We present the case of a patient with evidence of exposure to Borrelia burgdorferi sl and a long history of debilitating fatigue, cognitive abnormalities and autonomic nervous system issues...

Host genotype influences the severity of murine Lyme borreliosis, caused by the spirochetal bacterium Borrelia burgdorferi C57BL/6 (B6) mice develop mild, whereas C3H/HeN (C3H) mice develop severe Lyme arthritis. Differential expression of interleukin 10 (IL-10) has long been associated with mouse strain differences in Lyme pathogenesis; however, the underlying mechanism(s) of this genotype-specific IL-10 regulation remained elusive. Herein we reveal a cAMP-mediated mechanism of IL-10 regulation in B6 macrophages that is substantially diminished in C3H macrophages...

BACKGROUND: The tick Ixodes ricinus has considerable impact on the health of humans and other terrestrial animals because it transmits several tick-borne pathogens (TBPs) such as B. burgdorferi (sensu lato), which causes Lyme borreliosis (LB). Small forest patches of agricultural landscapes provide many ecosystem services and also the disservice of LB risk. Biotic interactions and environmental filtering shape tick host communities distinctively between specific regions of Europe, which makes evaluating the dilution effect hypothesis and its influence across various scales challenging...

The treatment of patients infected with Borrelia burgdorferi was the subject of studies by numerous experts. The discrepancy of the recommendations is quite significant, especially in the choice of antibiotic, which is most important in the first stage of infection. The recommended doxycycline is in all recommendations although its MIC90 is 2.0 mg/L. Other antibiotics have better parameters, especially azithromycin topically administered in the first stage of infection, can be fully effective. In addition to the morphological and immunological variability of Borrelia burgdorferi, antibiotics that have an ability to enter the cell, such as azithromycin, should be noted...

Conservation efforts are investigating the impact of diseases within a species of interest, including prevalence and transmission and morbidity and mortality rates. However, the majority of these studies focus solely on the characteristics of a single pathogen. Recently, the role of copathogens has been reported to impact disease susceptibility and mortality. To that effect, a survey was conducted including 318 eastern box turtles ( Terrapene carolina carolina) from populations in Illinois and Tennessee in 2014 and 2015...

Tick-borne relapsing fever (TBRF) is an acute infectious disease caused by arthropod-borne spirochetes of the genus Borrelia and characterized by recurrent episodes of fever. Borrelia persica, the causative agent of this disease in Israel, is transmitted by the argasid tick Ornithodoros tholozani. There is little information about the maintenance and possible vertebrate reservoirs of B. persica in nature, but the tick O. tholozani is known to feed on animals that enter its habitat in caves, rock crevices and shady environments...

The plant Coleus forskohlii is distributed primarily in India, Thailand, China, Egypt and Brazil and has a history of use in the treatment of multiple diseases. Isoforskolin (ISOF) is the principle active component of C. forskohlii native to China and has previously been studied for its biological effects. The aim of the present study was to evaluate the effect of ISOF on the proinflammatory responses induced by recombinant Borrelia burgdorferi basic membrane protein A (rBmpA). In in vitro experiments, the proinflammatory effects of rBmpA and the anti-inflammatory function of ISOF were evaluated in murine macrophages, human macrophages and dendritic cells by detecting the transcription and expression of tumor necrosis factor (TNF)-α and interleukin (IL)-6...

INTRODUCTION: Introduction and objective. Lyme disease (LD) is the most common vector-borne disease in the temperate zone of the Northern Hemisphere. Diagnosis of LD is mainly based on clinical symptoms supported with serology (detection of anti-<i>Borrelia</i> antibodies) and is often misdiagnosed in areas of endemicity. MATERIAL AND METHODS: In this study, the chimeric proteins (A/C-2, A/C-4 and A/C-7.1) consisting of B-cell epitopes of outer surface proteins OspA and OspC from <i>Borrelia</i> genospecies prevalent in Eastern Slovakia, were designed, over-expressed in <i>E...

Laboratory diagnosis of Lyme disease is difficult and presently dependent on detecting Borrelia burgdorferi-specific antibodies in patient serum with the disadvantage that the immune response to B. burgdorferi can be weak or variable, or alternatively, the slow and inefficient culture confirmation of B. burgdorferi. PCR tests have previously shown poor sensitivity and are not routinely used for diagnosis. We developed a sensitive and specific Lyme Multiplex PCR-dot blot assay (LM-PCR assay) applicable to blood and urine samples to supplement western blot (WB) serological tests for detecting B...
