South East corner of England is one of the worst areas in EUROPE for Lyme disease-carrying ticks

Researchers from across Europe, including the University of East London, mapped reports of the Lyme disease-causing Borrelia burgdorferi bacteria in ticks from 2010 to 2017.

Quantitative and microscopic tracking of Borrelia afzelii transmission from infected Ixodes ricinus nymphs has shown a transmission cycle different from that of Borrelia burgdorferi and Ixodes scapularis. Borrelia afzelii organisms are abundant in the guts of unfed I. ricinus nymphs, and their numbers continuously decrease during feeding. Borrelia afzelii spirochetes are present in murine skin within 1 day of tick attachment. In contrast, spirochetes were not detectable in salivary glands at any stage of tick feeding. Further experiments demonstrated that tick saliva is not essential for B. afzelii infectivity, the most im...

This study presented examples of base-calling DNA sequencing electropherograms routinely generated in a clinical diagnostic laboratory on DNA extracts of human blood specimens and ticks collected from human skin bites and from the environment. Since some of the tick samples tested were collected in Ireland, borrelial species or strains not known to exist in the United States were also detected by analysis of this 16S rRNA “core genome”. We recommend that hospital laboratories located in Lyme disease endemic areas begin to use a “core genome” sequencing test to routinely diagnose spir...

The diagnosis of acute Lyme disease is not straightforward. Therefore it is important to develop new strategies to improve diagnostic processes. Detailed analysis of patients’ B cell repertoires by High Throughput Sequencing (HTS) revealed antigen-associated “signatures” which have a huge potential to support diagnosis of acute infections. The human B cell immune response to Borrelia burgdorferi – the causative agent of Lyme disease – has mainly been studied at the antibody level, while less attention has been given to the cellular part of the humoral immune response. There are indications tha...

Abstract Vancomycin is active in vitro and in vivo in mouse systems against Lyme disease borrelia; however, there are no published data on the efficacy of vancomycin in patients with Lyme disease and no convincing theoretical advantages of vancomycin over the currently used and highly effective orally administered antimicrobial agents, including doxycycline, amoxicillin and cefuroxime axetil. In addition, vancomycin may cause a wide variety of potentially serious adverse effects and requires the placement of an intravenous catheter. It is concluded that vancomycin is a much less attractive option for the...

In this study, we compared factors that may have an influence on DNA extraction namely commercially available DNA extraction kits vs alkaline hydrolysis for DNA extraction. The methods were applied to questing Ixodes (I.) ricinus ticks and Borrelia cultures of defined cell concentrations. A total of 69 questing I. ricinus ticks were collected. From 34 ticks, total DNA was extracted using a commercial DNA extraction kit. Thirty-five ticks were treated with 1.25 % ammonium hydroxide (NH4OH). Six ticks from each batch were placed in 70 % ethanol (EtOH) for one week prior to DNA extraction to see the effect of EtOH preservatio...

Horm Metab Res 2019; 51: 326-329 DOI: 10.1055/a-0885-7169Dyslipidemia and dyslipoproteinemia are common causes of metabolic and cardiovascular diseases. On the other hand, intracellular bacteria, such as Borrelia burgdorferi, utilize host lipids to survive and disseminate within the host. Recent data suggest that elevated lipids are a contributing factor to the maintenance and severity of Lyme disease and its complications. Here we review and discuss the role of lipids in Borreliosis and report on a pilot trial to examine the potential roles of circulating lipids and lipoproteins in patients with Borrelia infection. In thi...

ConclusionsOur results show that Tp0136 facilitates differential level of binding to cell lines representing various host tissues, which highlights the importance of this protein in colonization of human organs byT.pallidum and resulting syphilis pathogenesis.

We report the case of a 62-year-old woman presenting with asymmetrical tetraparesis and hyporeflexia. Initially the presumed diagnosis of Guillain-Barré syndrome with a possible functional component was suspected and treatment with intravenous immunoglobulin was initiated. Due to partial response to therapy and further test results including positive serologies and cerebrospinal fluid antibodies for Borrelia, the diagnosis of neuroborreliosis was considered. Furthe r exploring revealed the possibility of exposure to ticks although there was no report of typical skin lesions. Daily physical therapy and appropriate an...

ConclusionsWith co-infection of tick-borne pathogens being commonplace, diagnostic improvements remain important. Developing in vivo models might allow more insight into human pathogenesis. Continued ecological and human case studies are key to better epidemiological understanding, guiding intervention strategies. PMID: 31064634 [PubMed - in process]
