Borrelia burgdorferi (sensu lato) is a complex containing pathogenic bacteria of which some species, such as Borrelia lusitaniae, use birds, small mammals and reptiles as reservoirs. In Italy, the bacteria have b...

We report the case of a 9-year-old girl who suffered from headaches for several days and was shown to have opsoclonus and left peripheral facial palsy. Work-up excluded the diagnosis of neuroblastoma, but CSF analysis showed aseptic meningitis, and serology for Borrelia burgdorferi (Lyme) was positive. The outcome was favorable with complete regression of symptoms after treatment with ceftriaxone 2g/day for 3 weeks. Although rare, the diagnosis of Lyme neuroborreliosis must be raised in the presence of isolated opsoclonus, particularly if the clinical picture is incomplete and if other features, such as peripheral fac...

In this study, we investigated tick-borne bacterial pathogens in wild boar, hare, and fox and their ticks in Turkey. A total of 102 tick pools comprised of 445 ticks and blood samples were analyzed for the presence of bacterial DNA by PCRs targeted rickettsial gltA and ompA genes, 5S-23S rDNA gene for Borrelia spp., and msp4 gene for Anaplasma spp. As a result of PCR and sequence analyses, three pathogenic spotted fever group (SFG) rickettsiae, two SFG rickettsiae with unknown pathogenicity and one pathogenic Borrelia burgdorferi sensu lato were detected in samples obtained from wild animals. Rickettsia slovaca was detecte...

Abstract It is still under investigation, whether all Borrelia sp. causing Lyme borreliosis and other diseases are already identified and properly classified as human pathogens. For this reason, it is of great importance to develop a diagnostic ELISA test that detects all Borrelia sp. The aim of this study was to identify conserved DNA and protein regions present in all currently known Borrelia sp. In experimental studies 31 available Borrelia sp. genomes were aligned and screened for the presence of evolutionary conserved regions. As a result of bioinformatics analysis, one evolutionally conserved DNA region enco...

In the United States, laboratories frequently offer multiple different assays for testing of cerebrospinal fluid (CSF) samples to provide laboratory support for the diagnosis of central nervous system Lyme disease (CNSLD). Often included among these diagnostic tests are the same enzyme immunoassays and immunoblots that are routinely used to detect the presence of antibodies to Borrelia burgdorferi in serum. However, performing these assays on CSF alone may yield positive results simply from passive diffusion of serum antibodies into the CSF. In addition, such tests are only U.S. Food and Drug Administration cleared and wel...

In conclusion, the perpetrator profiles of Samento and Banderol for herb–drug interactions completely differ. Clinical studies are strongly recommended to clarify whether the effects observed in vitro are of clinical relevance.

The pharmaco- and immunomodulatory properties of insect and acarine saliva play an essential role in the efficiency of pathogen transmission. The skin as the site where arthropod saliva and pathogens...

CONCLUSION: Lyme neuroborreliosis has a favorable prognosis if treated early. The long-term administration of antibiotics over many weeks or even months for putative chronic Lyme neuroborreliosis with nonspecific symptoms yields no additional benefit and carries the risk of serious adverse effects.
