Lyme carditis atrioventricular block: management strategies —Authors’ reply

We would like to thank Crinionet al.1 at Queen ’s university for their interest in our case report2 and for taking the time to contribute to the discussion. Crinionet al.1 discusses the role of permanent pacing in Lyme carditis and puts forth a systematic approach in such cases.

A basic feature of infection caused by Borrelia burgdorferi, the etiological agent of Lyme borreliosis, is that persistent infection is the rule in its many hosts. The ability to persist and evade host immune clearance poses a challenge to effective antimicrobial treatment. A link between therapy failure and the presence of persister cells has started to emerge. There is growing experimental evidence that viable but noncultivable spirochetes persist following treatment with several different antimicrobial agents. The current study utilized the mouse model to evaluate if persistence occurs following antimicrobial treatment ...

Semin Neurol 2019; 39: 440-447 DOI: 10.1055/s-0039-1692143Tick-borne infections—including tick-borne encephalitis viruses, represented in the United States by rare infections with Powassan and deer tick viruses, and more often Lyme disease—are of increasing importance to neurologists. Lyme neuroborreliosis (LNB) causes all or part of a triad including meningitis, radiculoneuritis, and cranial neuritis. Rarely, parenchymal brain and spinal cord involvement occur, with focal findings on examination and magnetic resonance imaging (MRI). LNB diagnosis requires plausible exposure, objective evidence of nervous syste...

Authors: Brodziński S, Nasierowski T Abstract In the second part of the article case reports of three patients were presented. All patientswere treated for Borrelia infection and all of them developed psychotic disorders. History of each patient was different, as well as the probability of causal relationship between neuroborreliosis and psychosis. The first case concerns a female patient with no former psychiatric history, who developed psychotic episode secondary to neuroborreliosis. Psychotic disorders resolved after antibiotic treatment. In the second case, a male patient was previously twice hospitalized in p...

Authors: Brodziński S, Nasierowski T Abstract Borreliosis is a multisystem, bacterial, zoonotic infectious disease with diversified spectrumof symptoms, which may also include psychotic disorders. Clinical picture of the disease is often unspecific, which makes the diagnosis relatively difficult. Uncharacteristic process of borreliosis is a result of complex molecular strategies used by spirochetes to infect, disseminate and survive in host organism. Part I of the article is focused on the current knowledge about pathogenesis of Lyme Borreliosis (LB), especially neuroborreliosis. Additionally, epidemic situation i...

Hickling, Nicholas H. Ogden, Roger A. LeBrun, Jean I. TsaoAbstractIxodes scapularis is the primary vector of Lyme disease spirochetes in eastern and central North America, and local densities of this tick can affect human disease risk. We sampled larvae and nymphs from sites in Massachusetts and Wisconsin, USA, using flag/drag devices and by collecting ticks from hosts, and measured environmental variables to evaluate the enviro...

ConclusionsC. burnetii is rarely transmitted by ticks, but we proved that it is present in the environment, so it may be a danger to humans. The most common co-occurrence after tick bite concernsC. burnetii andB. burgdorferi.

The periplasmic lipoprotein BB0365 of the Lyme disease agentBorrelia burgdorferi is expressed throughout mammalian infection and is essential for all phases of Lyme disease infection; its function, however, remains unknown. In the current study, our structural analysis of BB0365 revealed the same structural fold as that found in the NqrC and RnfG subunits of the NADH:quinone and ferredoxin:NAD+ sodium ‐translocating oxidoreductase complexes, which points to a potential role for BB0365 as a component of the sodium pump. Additionally, BB0365 coordinated Zn2+ by the His51, His55, His140 residues, and the Zn2+‐binding...
