Controversies About Lyme Disease —Reply

In Reply Mr Tuttle and Mr Santarella and Dr Sellati cite data from passive surveillance systems as evidence that our statement that erythema migrans develops in 90% or more of patients with Lyme disease was inaccurate. However, multiple large clinical studies have estimated the proportions of pediatric and adult patients with Lyme disease with erythema migrans. These estimates, which are much more reliable because patients were carefully assessed for the presence of erythema migrans, have consistently equaled or exceeded 90%. Lower proportions (eg, 70%) among cases reported to the CDC likely reflect reporting bias toward clinical manifestations associated with seropositivity. The CDC also estimates that 90% of cases of Lyme disease go unreported. Among cases reported to the CDC, 30% had Lyme arthritis, in contrast to the 6% or lower frequency of this manifestation in prospective clinical studies.

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...

I was speaking with someone recently who has a series of chronic and painful conditions; some of which are noticeable and some ‘invisible’. What is particularly distressful is that people sometimes say to her, “At least you don’t have cancer.” How dismissive is that? I know they are trying to help her feel better about what she does have and perhaps even attempt to minimize the impact, but it is not compassionate or helpful. There are diagnoses such as fibromyalgia, lupus, diabetes, arthritis or neuropathy which some people have to navigate. It might mean taking naps on an as-needed basis, en...

In conclusion, we unraveled the secretome of G. adiacens, an oral bacterium well-documented in infective endocarditis, but also recently shown to be involved in oral infections. Importantly, the secretome of G. adiacens comprised of a large number of putative virulence factors. Of particular importance is the finding that the G. adiacens secretome comprised of a number of “moonlighting” proteins, which in other species are shown to enhance bacterial colonization and virulence through their multifunctional roles (Pavkova et al., 2017; Graf et al., 2019). Thus, our results provide a basis for investigating the ro...

Lyme disease is caused by the spirochete Borrelia burgdorferi and is transmitted via the bite of an infected tick. B. burgdorferi enters the skin, disseminates via the bloodstream, and infects various distal tissues, leading to inflammatory sequelae, such as Lyme arthritis and Lyme carditis. B. burgdorferi linear plasmid 36 (lp36) is critical for mammalian infectivity; however, the full complement of genes on lp36 that contribute to this process remains unknown. Through a targeted mutagenesis screen of the genes on lp36, we identified a novel infectivity gene of unknown function, bbk13, which encodes an immunogenic, non-su...

Abstract Lyme disease, reffered to as Lyme borreliosis, is a tick-borne zoonotic disease caused by Borrelia burgdorferi spirochetes. Lyme arthritis, the most common, serious and harmful manifestation during the late stages of Lyme disease, is closely associated with the Borrelia burgdorferi basic membrane protein A (BmpA). Chemokines are also reported to have an important role in Lyme arthritis. Toll-like receptors (TLRs) recognize and bind to pathogen-associated molecules which are structurally conserved among microbes, to activate transcriptional events, including cytokine production, inflammation, and tissue da...

Unlike typical Fur proteins in which DNA binding represses gene expression, binding of BosR to the rpoS promoter directly activates rpoS transcription in B. burgdorferi. However, virtually nothing is known concerning potential structural fea...
