[Seminar] Lyme borreliosis

LANCET — Sat, 04 Feb 2012 05:00:00 +0100

Lyme borreliosis (Lyme disease) is caused by spirochaetes of the Borrelia burgdorferi sensu lato species complex, which are transmitted by ticks. The most common clinical manifestation is erythema migrans, which eventually resolves, even without antibiotic treatment. However, the infecting pathogen can spread to other tissues and organs, causing more severe manifestations that can involve a patient's skin, nervous system, joints, or heart. The incidence of this disease is increasing in many countries. (Source: LANCET)

The geographic pattern of human risk for infection with Borrelia burgdorferi sensu stricto, the tick-borne pathogen that causes Lyme disease, was mapped for the eastern United States. The map is based on standardized field sampling in 304 sites of the density of Ixodes scapularis host-seeking nymphs infected with B. burgdorferi, which is closely associated with human infection risk. Risk factors for the presence and density of infected nymphs were used to model a continuous 8 km×8 km resolution predictive surface of human risk, including confidence intervals for each pixel.

Authors: Ruiz-Fons F, Fernández-de-Mera IG, Acevedo P, Gortázar C, de la Fuente J Abstract Environmental factors may drive tick ecology and therefore tick-borne pathogen (TBP) epidemiology, which determines the risk of animals and humans of getting infected by TBPs. For this reason, the aim of this study was to analyze the influence of environmental factors on the abundance of immature stages of Ixodes ricinus and on the prevalence of two zoonotic I. ricinus-borne pathogens in endemic natural foci. I. ricinus abundance was measured in nine sites in northern Iberian Peninsula by dragging the vegetation with a cotton flannelette and ungulate abundance was measured by means of dung counts. In addition to ungulate abundance, variables related to spatial location, climate and soil wer...

CD14 cooperates with complement receptor 3 to mediate MyD88-independent phagocytosis of Borrelia burgdorferi [Immunology]

Proceedings of the National Academy of Sciences — Tue, 24 Jan 2012 05:00:00 +0100

Phagocytosis of Borrelia burgdorferi, the causative agent of Lyme disease, is a poorly understood process, despite its importance during the host immune response to infection. B. burgdorferi has been shown to bind to different receptors on the surface of phagocytic cells, including the β2 integrin, complement receptor 3 (CR3). However, whether these receptors mediate the phagocytosis of the spirochete remains unknown. We now demonstrate that CR3 mediates the phagocytosis of the spirochete by murine macrophages and human monocytes. Interaction of B. burgdorferi with the integrin is not sufficient, however, to internalize the spirochete; phagocytosis requires the interaction of CR3 with the GPI-anchored protein, CD14, independently of TLR/MyD88-induced or inside-out signals. Interestingly, ...

Potential Infectious Etiology of Behçet's Disease.

Herpes — Fri, 20 Jan 2012 03:30:02 +0100

Authors: Galeone M, Colucci R, D'Erme AM, Moretti S, Lotti T Abstract Behçet's disease is a multisystem inflammatory disorder characterized by recurrent oral aphthous ulcers, genital ulcers, uveitis, and skin lesions. The cause of Behçet's disease remains unknown, but epidemiologic findings suggest that an autoimmune process is triggered by an environmental agent in a genetically predisposed individual. An infectious agent could operate through molecular mimicry, and subsequently the disease could be perpetuated by an abnormal immune response to an autoantigen in the absence of ongoing infection. Potentia bacterial are Saccharomyces cerevisiae, mycobacteria, Borrelia burgdorferi, Helicobacter pylori, Escherichia coli, Staphylococcus aureus, and Mycoplasma fermentans, but the most...

Authors: Smith FD, Ballantyne R, Morgan ER, Wall R Abstract The reported number of cases of Lyme disease, Borrelia burgdorferi sensu lato, is thought to have increased in the UK over the past decade, but consistent surveillance data are lacking. Here the prevalence of B. burgdorferi in ticks attached to pet dogs was examined - using them as sentinels for human disease risk. Dogs give a good indication of the exposure of their human owners to infected ticks, since they largely share the same environment and visit the same outdoor areas. PCR was used to test 739 tick samples collected from 3534 dogs selected at random as they visited veterinary practices over a period of six months. Overall, the prevalence of infected ticks on all dogs was 0.5% giving an estimated 481 infected ticks ...

The BB0646 protein demonstrates lipase and haemolytic activity associated with Borrelia burgdorferi, the aetiological agent of Lyme disease

Molecular Microbiology — Sun, 11 Dec 2011 05:00:00 +0100

SummaryThe etiological agent of Lyme disease, Borrelia burgdorferi, is transmitted by ticks of the Ixodes genus and, if untreated, can cause significant morbidity in affected individuals. Recent reports have shown that polyunsaturated fatty acids in the B. burgdorferi cell envelope are potential targets for oxidative damage, which can be lethal. How B. burgdorferi responds to this assault is not known. Herein we report evidence that bb0646 codes for a lipase that is located within the bosR operon and that has specificity for both saturated and polyunsaturated fatty acids. Specifically, strains harbouring mutated copies of the lipase, either in the form of an insertionally inactivated construct or site‐directed mutations within the active site, demonstrated attenuated lipolytic and ha...

AbstractAlthough it is known that two‐tier serologic testing for Lyme disease may be associated with false positive results on the IgM immunoblot, this problem has never been systematically studied in the clinical practice setting. In a retrospective investigation of patients referred to the private adult practice of an Infectious Diseases physician for possible for Lyme disease, 50 of 182 patients (27.5%, 95% CI: 21.1‐34.6) were found to have a false positive IgM immunoblot. 78.0% of these patients had received unnecessary antibiotic therapy. False positive results were not restricted to any single commercial laboratory. Research on alternative testing strategies that eliminate the IgM immunoblot entirely is warranted.

A diagnosis of Lyme disease should not be ruled out based on a short tick attachment time in a subject with clinical evidence of B. burgdorferi infection.

Authors: Poljak A, Comstedt P, Hanner M, Schüler W, Meinke A, Wizel B, Lundberg U Abstract The three Borrelia species, Borrelia afzelii, Borrelia burgdorferi and Borrelia garinii are the main species causing the most common tick-borne zoonosis, Lyme borreliosis. By applying a genomic approach relying on human antibodies we have identified 122 antigenic Borrelia proteins associated with Lyme borreliosis, including already known and published protective antigens. The heterogeneity of the Borrelia species causing Lyme borreliosis makes the search for conserved antigens providing broad protection challenging. Using several in vitro assays we narrowed down the selection to 15 vaccine candidates. These antigens were further analyzed for antigenicity and cross-reactivity using sera from ...

AbstractAlthough tick‐borne encephalitis (TBE) has been recognized in Europe for more than 70 years and has been the topic of numerous reports, information on the involvement of facial nerve in the course of the disease is limited. Our study conducted at a single medical centre revealed that facial nerve involvement in the course of TBE in Central Europe is a) infrequent – it was found in only 11 of 1218 (0.9%) consecutive adult patients diagnosed with TBE; b) manifests with unilateral or rarely bilateral peripheral facial palsy (PFP) (9 and 2 patients, respectively); c) appears late in the course of acute illness – in our patients 10–20 days after the onset of the meningoencephalitic phase of TBE, and often after defervescence (in 8/11 patients; 6–13 days after normalisation of ...

Pervasive Recombination and Sympatric Genome Diversification Driven by Frequency-Dependent Selection in Borrelia burgdorferi, the Lyme Disease Bacterium [Population and Evolutionary Genetics]

Genetics — Mon, 14 Nov 2011 05:00:00 +0100

How genomic diversity within bacterial populations originates and is maintained in the presence of frequent recombination is a central problem in understanding bacterial evolution. Natural populations of Borrelia burgdorferi, the bacterial agent of Lyme disease, consist of diverse genomic groups co-infecting single individual vertebrate hosts and tick vectors. To understand mechanisms of sympatric genome differentiation in B. burgdorferi, we sequenced and compared 23 genomes representing major genomic groups in North America and Europe. Linkage analysis of >13,500 single-nucleotide polymorphisms revealed pervasive horizontal DNA exchanges. Although three times more frequent than point mutation, recombination is localized and weakly affects genome-wide linkage disequilibrium. We show by ...

Annals of the Rheumatic Diseases — Wed, 02 Nov 2011 04:00:00 +0100

Invariant natural killer T (iNKT) cells belong to a prototypical regulatory T cell lineage that functions at the interface of innate immunity and adaptive immunity. Unlike peptide-restricted T cells, iNKT cells recognise and respond to various glycolipid antigens presented in the context of the major histocompatibility complex class I-like molecule CD1d.1 iNKT cells possess a number of unique effector functions, including the ability to rapidly secrete large quantities of Th1, Th2 and Th17 cytokines, and, as such, have had a number of regulatory functions assigned to them. Consequently, iNKT cells are able to regulate a large number of bystander cells that form part of the innate and adaptive immune systems, and iNKT cell biology has subsequently been linked to a broad range of diseases, i...

Ecology ofBorrelia burgdorferisensu lato in Europe: transmission dynamics in multi‐host systems, influence of molecular processes and effects of climate change.

FEMS Microbiology Reviews — Tue, 01 Nov 2011 04:00:00 +0100

AbstractThe analysis of different multi‐host systems suggests that even hosts that are not capable of transmitting Borrelia burgdorferi sensu lato (sl) to the tick vector, Ixodes ricinus, or that are secondary reservoirs for these agents contribute to the intensity of transmission and to the overall risk of Lyme borreliosis, through the process of vector augmentation and pathogen amplification. On the other hand, above certain threshold densities, or in the presence of competition with primary reservoir hosts or low attachment rate of ticks to reservoir hosts, incompetent or less competent hosts may reduce transmission through dilution. The transmission of B. burgdorferi sl is affected by molecular processes at the tick‐host interface including mechanisms for the protection of spiroche...

Alessandra Luchini: nanoparticle traps detect diseases before our bodies do

Guardian Unlimited Science — Sat, 22 Oct 2011 23:03:00 +0100

A brilliant molecular-level test for signs of cancers developed by Alessandra Luchini promises far-reaching applicationsAlessandra Luchini is an engineer at George Mason University, Washington DC. Enabled by a grant from the Italian health service, she travelled to the US to study the molecular signs that some cancers release into the bloodstream. She was recently named in Popular Science's 'Brilliant 10' – an award for the achievements of scientists under 30.Why did you choose this line of research? We know that cancers have biomarkers that exist in the blood and body fluid in very low concentration, but they are volatile and degrade very quickly. So we were looking for something that current technology did not allow us to seek. We needed to figure out some kind of answer to that.Why di...

Herpes virus type 2 DNA was detected by PCR in the cerebrospinal fluid in a young woman presenting with headache, stiff neck and pleocytosis, and serological findings consistent with reactivation. Since she was exposed to ticks, Lyme disease and tick-borne encephalitis were excluded. Further investigation in an ongoing project, using PCR and sequencing of the amplified products, showed the presence of Rickettsia helvetica in the cerebrospinal fluid. The bacteria were also isolated in Vero cell culture, and microimmunofluorescence confirmed the development of antibodies against Rickettsia spp. with predominance of IgM reactivity consistent with recent infection. She was treated with antibiotics and improved rapidly. The patient could easily have been judged to have isolated herpes meningiti...

Hepoxilins in cancer and inflammation—use of hepoxilin antagonists

Cancer and Metastasis Reviews — Mon, 17 Oct 2011 16:03:30 +0100

Abstract Cancer is often accompanied with inflammatory, thrombotic, and diabetic complications. Alternatively, chronic inflammation is believed to be a causative factor in several cancers. This review article brings together reported biological actions in these areas of the unstable naturally derived hepoxilins (HX), metabolites of arachidonic acid formed through the 12-LO pathway, and those of their synthetically derived stable HX antagonists (PBT; proprietary bioactive therapeutics). Although the HX pathway has been known for some three decades since its discovery by the author with much data originating from the author’s laboratory, studies by others over the past few years have confirmed early findings of the actions of HX as potent pro-inflammatory chemoattractant m...

Carbon storage regulator A (CsrABb) is a repressor of Borrelia burgdorferi flagellin protein FlaB

Molecular Microbiology — Fri, 14 Oct 2011 04:00:00 +0100

In this report, we deciphered the regulatory role of CsrABb on FlaB synthesis and the mechanism involved by analyzing two mutants, csrABb‐ (a deletion mutant of csrABb) and csrABb+ (a mutant conditionally over‐expressing csrABb). We found that FlaB accumulation was significantly inhibited in csrABb+ but was substantially increased in csrABb‐. In contrast, the levels of other flagellar proteins remained unchanged. Cryo‐electron tomography and immuno‐fluorescence microscopic analyses revealed that the altered synthesis of CsrABb in these two mutants specifically affected flagellar filament length. The leader sequence of flaB transcript contains two conserved CsrA‐binding sites, with one of these sites overlapping the Shine‐Dalgarno sequence. We found that CsrABb bound to the fl...

Molecular characterization of the Borrelia burgdorferi in vivo-essential protein PncA.

Microbiology — Sat, 01 Oct 2011 04:00:00 +0100

Authors: Jewett MW, Jain S, Linowski AK, Sarkar A, Rosa PA Abstract The conversion of nicotinamide to nicotinic acid by nicotinamidase enzymes is a critical step in maintaining NAD(+) homeostasis and contributes to numerous important biological processes in diverse organisms. In Borrelia burgdorferi, the nicotinamidase enzyme, PncA, is required for spirochaete survival throughout the infectious cycle. Mammals lack nicotinamidases and therefore PncA may serve as a therapeutic target for Lyme disease. Contrary to the in vivo importance of PncA, the current annotation for the pncA ORF suggests that the encoded protein may be inactive due to the absence of an N-terminal aspartic acid residue that is a conserved member of the catalytic triad of characterized PncA proteins. Herein, we ha...

Ticks were screened for Rickettsia spp., Borrelia spp., and Ehrlichia spp. by using polymerase chain reaction. Forty-one (14.3%) ticks (31 A. americanum and 10 D. variabilis) were polymer...

Humans Infected with Relapsing Fever Spirochete Borrelia miyamotoi, Russia.

Emerging Infectious Diseases — Sat, 01 Oct 2011 04:00:00 +0100

We report 46 cases of B. miyamotoi infection in humans and compare the frequency and clinical manifestations of this infection with those caused by B. garinii and B. burgdorferi infection. All 46 patients lived in Russia and had influenza-like illness with fever as high as 39.5°C; relapsing febrile illness occurred in 5 (11%) and erythema migrans in 4 (9%). In Russia, the rate of B. miyamotoi infection in Ixodes persulcatus ticks was 1%-16%, similar to rates in I. ricinus ticks in western Europe and I. scapularis ticks in the United States. B. miyamotoi infection may cause relapsing fever and Lyme disease-like symptoms throughout the Holarctic region of the world because of the widespread prevalence of this pathogen in its ixodid tick vectors.

Evaluation of skin thickness lesions in patients with Lyme disease measured by modified Rodnan total skin score

Rheumatology International — Fri, 30 Sep 2011 05:53:01 +0100

Abstract Recently, a possible etiological connection between infection with Borrelia burgdorferi and various skin lesions, including morphea and systemic sclerosis (SSc), has been discussed. The aim of our study was the evaluation of frequency of skin thickening typical of SSc or morphea in the group of patients with Lyme disease (LD) with frequent exposition to tick bites. The group consisted of 110 patients with LD frequently exposed to tick bites form the northeastern Poland, which is an endemic area for this disease. To measure the skin lesions, the modified Rodnan total skin score (RTSS) was used. In the analyzed group, no skin changes typical of morphea or skin thickening were found. According to RTSS, all patients scored 0 points. Raynaud’s phenomenon in all patien...

Nervous System Lyme Disease: Is There a Controversy?

Semin Neurol 2011; 31: 317-324DOI: 10.1055/s-0031-1287652ABSTRACTInfection with the tick-borne spirochete, Borrelia burgdorferi, affects the nervous system in well-defined ways. Accurate diagnostic tools and effective therapeutic regimens are now well established. Persistent misconceptions about (1) the role and interpretation of laboratory tests, (2) what is and is not evidence of nervous system infection, and (3) what constitutes an expected response to treatment have fostered widespread perceptions that this disease is highly controversial. Infection causes the classically described triad of meningitis, radiculoneuritis, and cranial neuritis; however, virtually every known neurologic disorder has been blamed on this infection.

Host races in Ixodes ricinus, the European vector of Lyme borreliosis.

Infection, Genetics and Evolution — Thu, 29 Sep 2011 04:00:00 +0100

Authors: Kempf F, De Meeûs T, Vaumourin E, Noel V, Taragel'ová V, Plantard O, Heylen DJ, Eraud C, Chevillon C, McCoy KD Abstract Ixodes ricinus is a European tick that transmits numerous pathogenic agents, including the bacteria that cause Lyme disease (some genospecies of Borrelia burgdorferi sensu lato complex). This tick has been considered as a classic example of an extreme generalist vector. However, host-associations in such vector species are difficult to determine from field observations alone and recent work suggests that host specificity may be more frequent in ticks than previously thought. The presence of host-associated vector groups can significantly alter the circulation and evolutionary pathway of associated pathogens. In this paper, we explicitly test for host-as...

We report two cases of Lyme disease-associated glomerulonephritis. A 57-year-old female presented with rash, volume overload, hypertension and rapidly progressive glomerulonephritis. Biopsy confirmed an immune complex-mediated, membranoproliferative lesion. She was treated successfully with steroids and antibiotics. In a second case, a 40-year-old male, with a previously known microscopic hematuria, presented with rash, arthralgias, new proteinuria and gross hematuria following a tick bite. Biopsy revealed focal proliferative IgA nephropathy. Treatment with steroids and antibiotics resulted in rapid resolution of findings.

The coenzyme A disulphide reductase of Borrelia burgdorferi is important for rapid growth throughout the enzootic cycle and essential for infection of the mammalian host

Molecular Microbiology — Fri, 16 Sep 2011 04:00:00 +0100

SummaryIn a microarray analysis of the RpoS regulon in mammalian host‐adapted Borrelia burgdorferi, bb0728 (cdr) was found to be dually transcribed by the sigma factors σ70 and RpoS. The cdr gene encodes a coenzyme A disulphide reductase (CoADR) that reduces CoA‐disulphides to CoA in an NADH‐dependent manner. Based on the abundance of CoA in B. burgdorferi and the biochemistry of the enzyme, CoADR has been proposed to play a role in the spirochaete's response to reactive oxygen species. To better understand the physiologic function(s) of BbCoADR, we generated a B. burgdorferi mutant in which the cdr gene was disrupted. RT‐PCR and 5′‐RACE analysis revealed that cdr and bb0729 are co‐transcribed from a single transcriptional start site upstream of the bb0729 coding sequenc...

Reservoir Targeted Vaccine for Lyme Borreliosis Induces a Year Long, Neutralizing Antibody Response to OspA in White-footed Mice.

Clinical and Vaccine Immunology — Wed, 14 Sep 2011 04:00:00 +0100

Authors: Meirelles Richer L, Aroso M, Contente-Cuomo T, Ivanova L, Gomes-Solecki M Abstract Lyme disease is caused by the spirochete Borrelia burgdorferi. The enzootic cycle of this pathogen requires that Ixodes spp. acquire B. burgdorferi from infected wildlife reservoirs and transmit it to other uninfected wildlife. At present, there are no effective measures to control B. burgdorferi; there is no human vaccine available, and existing vector control measures are generally not acceptable to the public. However, if B. burgdorferi could be eliminated from its reservoir hosts or from the ticks that feed on them, the enzootic cycle would be broken, and the incidence of Lyme disease would decrease. We developed a reservoir targeted bait vaccine (RTV) based on the immunogenic outer surf...

SummaryAdvocacy for Lyme disease has become an increasingly important part of an antiscience movement that denies both the viral cause of AIDS and the benefits of vaccines and that supports unproven (sometimes dangerous) alternative medical treatments. Some activists portray Lyme disease, a geographically limited tick-borne infection, as a disease that is insidious, ubiquitous, difficult to diagnose, and almost incurable; they also propose that the disease causes mainly non-specific symptoms that can be treated only with long-term antibiotics and other unorthodox and unvalidated treatments.

Widespread dispersal of Borrelia burgdorferi-infected ticks collected from songbirds across Canada.

The Journal of Parasitology — Tue, 23 Aug 2011 23:00:00 +0100

We report transstadial transmission (larva to nymph) of B. burgdorferi in I. auritulus. Data suggest a possible 4-tick, i.e., I. angustus, I. auritulus, I. pacificus, and I. spinipalpis enzootic cycle of B. burgdorferi on Vancouver Island, British Columbia. Our results suggest that songbirds infested with B. burgdorferi-infected ticks have the potential to start new tick populations endemic for Lyme disease. Because songbirds disperse B. burgdorferi-infected ticks outside their anticipated range, health-care providers are advised that people can contract Lyme disease locally without any history of travel.

Asymptomatic Macrothrombocytopenia in a Young Pure-Bred Beagle Dog: A Case Report.

Toxicologic Pathology — Sun, 21 Aug 2011 23:00:00 +0100

Authors: Bodié K, Gagne GD, Sramek MK, Desmond DJ, Abel SJ, Fagerland JA Abstract During baseline evaluation prior to a preclinical safety study, a 10-month-old male pure-bred Beagle dog was found to have marked thrombocytopenia (6 × 103 platelets [PLT]/µL) associated with a mean platelet volume (MPV) of 17.9 fL. Tests for Rickettsia rickettsii, Ehrlichia canis, and Borrelia burgdorferi were negative. Buccal bleeding time was normal. Over 3 months, PLT were 4 to 141 × 103 PLT/µL, and MPV was 11.4 to 25.1 fL; however, PLT were <50 × 103 PLT/µL and MPV was >16 fL during most of this period. Antinuclear antibody (ANA) and anti-PLT antibody tests were negative. Genotyping for the presence of a beta 1-tubulin mutation demonstrated the normal wild-type gene. Treatment with p...

Following a Tick Bite: Double Infections by Tick‐Borne Encephalitis Virus and the Spirochete Borrelia and Other Potential Multiple Infections

Zoonoses and Public Health — Sat, 20 Aug 2011 17:12:10 +0100

SummaryIn Central Europe and large parts of Asia, tick‐borne‐encephalitis (TBE) and Lyme borreliosis caused by the spirochetal bacterium of the genus Borrelia are among the most common diseases transmitted by the bite of a tick. When in regions with overlapping TBE virus and Borrelia endemicity, a tick bite causes the victim to become ill, it is important that appropriate serological and other laboratory investigations form part of the differential diagnosis. Account must always be taken of the fact that a tick bite may be followed by a double infection with the TBE virus and Borrelia. For this reason, a comprehensive diagnostic work‐up aimed at detecting co‐infection by both pathogens, even when the tick bite occurs in an endemic region for both pathogens but the initial clinical ...

Bioluminescent imaging of Borrelia burgdorferi in vivo demonstrates that the fibronectin binding protein BBK32 is required for optimal infectivity

Molecular Microbiology — Thu, 18 Aug 2011 23:00:00 +0100

SummaryThe etiologic agent of Lyme disease, Borrelia burgdorferi, is transmitted via infected Ixodes spp. ticks. Infection, if untreated, results in dissemination to multiple tissues and significant morbidity. Recent developments in bioluminescence technology allow in vivo imaging and quantification of pathogenic organisms during infection. Herein, luciferase‐expressing B. burgdorferi and strains lacking the decorin adhesins DbpA and DbpB, as well as the fibronectin adhesin BBK32, were quantified by bioluminescent imaging to further evaluate their pathogenic potential in infected mice. Quantification of bacterial load was verified by quantitative PCR (qPCR) and cultivation. B. burgdorferi lacking DbpA and DbpB were only seen at the 1 h time point post‐infection, consistent with its low...

A tick mannose-binding lectin inhibitor interferes with the vertebrate complement cascade to enhance transmission of the lyme disease agent.

Cell Host and Microbe — Wed, 17 Aug 2011 23:00:00 +0100

Authors: Schuijt TJ, Coumou J, Narasimhan S, Dai J, Deponte K, Wouters D, Brouwer M, Oei A, Roelofs JJ, van Dam AP, van der Poll T, Van't Veer C, Hovius JW, Fikrig E Abstract The Lyme disease agent Borrelia burgdorferi is primarily transmitted to vertebrates by Ixodes ticks. The classical and alternative complement pathways are important in Borrelia eradication by the vertebrate host. We recently identified a tick salivary protein, designated P8, which reduced complement-mediated killing of Borrelia. We now discover that P8 interferes with the human lectin complement cascade, resulting in impaired neutrophil phagocytosis and chemotaxis and diminished Borrelia lysis. Therefore, P8 was renamed the tick salivary lectin pathway inhibitor (TSLPI). TSLPI-silenced ticks, or ticks exposed ...

Quantitation of cell-associated borrelial DNA in the blood of Lyme disease patients with erythema migrans

European Journal of Clinical Microbiology and Infectious Diseases — Mon, 15 Aug 2011 05:33:16 +0100

This study was designed to measure the level of Borrelia burgdorferi in the plasma of Lyme disease patients and correlate these levels with selected clinical and laboratory findings. Nested and quantitative polymerase chain reaction (qPCR) was employed to detect cell-associated flaB gene DNA in the plasma of untreated early Lyme disease patients with erythema migrans (EM). Twenty-nine (45.3%) of 64 patients had evidence of B. burgdorferi in their plasma by at least one of the PCR methods. For the 22 qPCR-positive patients, the mean number of flaB gene copies per mL of plasma was 4,660, with a range of 414 to 56,000. The number of flaB gene copies did not significantly correlate with any of the clinical, demographic, or laboratory variables assessed. For reasons discussed, we suggest ca...

Presence of Borrelia burgdorferi sensu lato antibodies in the serum of patients with abdominal aortic aneurysms

European Journal of Clinical Microbiology and Infectious Diseases — Sat, 13 Aug 2011 06:06:52 +0100

Abstract Infectious agents are likely to play a role in the pathogenesis of chronic inflammatory diseases, including abdominal aortic aneurysms (AAAs). The goal of this study was to determine if Borrelia burgdorferi sensu lato (sl), a microorganism responsible for Lyme disease, is involved in the etiology of AAAs. The presence of serum antibodies against B. burgdorferi sl was measured with enzyme-linked immunosorbent assay (ELISA) and confirmed by Western blotting in 96 AAA and 108 peripheral artery disease (PAD) patients. Polymerase chain reaction (PCR) was used for the detection of Borrelia-specific DNA in the aneurysm wall. Among AAA patients 34% and among PAD patients 16% were seropositive for B. burgdorferi sl antibodies (Fisher’s exact test, p = 0.003; odds ratio ...

NMR structure of an acyl-carrier protein from Borrelia burgdorferi

Acta Crystallographica Section F — Fri, 12 Aug 2011 23:00:00 +0100

Nearly complete resonance assignment and the high-resolution NMR structure of the acyl-carrier protein from Borrelia burgdorferi, a target of the Seattle Structural Genomics Center for Infectious Disease (SSGCID) structure-determination pipeline, are reported. This protein was chosen as a potential target for drug-discovery efforts because of its involvement in fatty-acid biosynthesis, an essential metabolic pathway, in bacteria. It was possible to assign >98% of backbone resonances and >92% of side-chain resonances using multidimensional NMR spectroscopy. The NMR structure was determined to a backbone r.m.s.d. of 0.4 Å and contained four α-helices and two 310-helices. A structure-homology search revealed that this protein is highly similar to the acyl-carrier protein from Aquifex aeol...

Identification of membrane associated drug targets in Borrelia burgdorferi ZS7- subtractive genomics approach.

Bioinformation — Fri, 05 Aug 2011 11:30:05 +0100

In this study, 272 essential proteins were identified out of which 42 proteins were unique to the microorganism. The study identified 15 membrane localized drug targets. Amongst these 15, molecular modeling and structure validation of the five membrane localized drug target proteins could only be achieved because of the low sequence identity of the remaining proteins with RCSB structures. These 3D structures can be further characterized by invitro and invivo studies for the development of novel vaccine epitopes and novel antibiotic therapy against Borrelia burgdorferi.

Population genetics, taxonomy, phylogeny and evolution of Borrelia burgdorferi sensu lato.

Infection, Genetics and Evolution — Thu, 04 Aug 2011 23:00:00 +0100

Authors: Margos G, Vollmer SA, Ogden NH, Fish D Abstract In order to understand the population structure and dynamics of bacterial microorganisms, typing systems that accurately reflect the phylogenetic and evolutionary relationship of the agents are required. Over the past 15years multilocus sequence typing schemes have replaced single locus approaches, giving novel insights into phylogenetic and evolutionary relationships of many bacterial species and facilitating taxonomy. Since 2004, several schemes using multiple loci have been developed to better understand the taxonomy, phylogeny and evolution of Lyme borreliosis spirochetes and in this paper we have reviewed and summarized the progress that has been made for this important group of vector-borne zoonotic bacteria.

Interferon-γ Influences the Composition of Leukocytic Infiltrates in Murine Lyme Carditis.

The American Journal of Pathology — Wed, 03 Aug 2011 23:00:00 +0100

Authors: Sabino GJ, Hwang SJ, McAllister SC, Mena P, Furie MB Interferon (IFN)-γ is present in lesions of patients with Lyme disease and positively correlates with the severity of manifestations. To investigate the role of IFNγ in the development of Lyme carditis, wild-type and IFNγ-deficient C57BL/6 mice were infected with the causative bacterium, Borrelia burgdorferi. Histological analysis revealed no change in the severity of carditis between wild-type and IFNγ-deficient mice at 14, 21, 25, and 28 days after infection. However, a distinct shift in the types of leukocytes within the hearts of IFNγ-deficient mice was observed at 25 days. In the absence of IFNγ, the number of neutrophils in the heart was increased, whereas the number of T lymphocytes was decreased. Bacterial load...
