Vector Interactions and Molecular Adaptations of Lyme Disease and Relapsing Fever Spirochetes Associated with Transmission by Ticks

Emerging Infectious Diseases, 2002
Pathogenic spirochetes in the genus Borrelia are transmitted primarily by two families of ticks. The Lyme disease spirochete, Borrelia burgdorferi, is transmitted by the slow-feeding ixodid tick Ixodes scapularis, whereas the relapsing fever spirochete ...

Protein Secretion in Spirochetes [PDF]

Microbiology Spectrum, 2019
ABSTRACT Spirochetes form a separate phylum of bacteria with two membranes but otherwise unusual morphologies and envelope structures. Distinctive common features of Borrelia , Leptospira , and Treponema include the sequestration of flagella to the periplasm ...

Engineered surface strategies to manage dental implant‐related infections

Periodontology 2000, EarlyView.
Abstract When exposed to the oral environment, dental implants, like natural surfaces, become substrates for microbial adhesion and accumulation, often leading to implant‐related infections—one of the main causes of implant failure. These failures impose significant costs on patients, clinicians, and healthcare systems.

Identification of cannabinoid-sensitive and -resistant oral bacteria

Frontiers in Microbiology
Marijuana, an emerging risk factor for periodontitis, contains multiple potent antibacterials, particularly the phytocannabinoids. Microbial dysbiosis is a hallmark of this destructive oral disease. We examined a panel of oral bacteria for susceptibility

Transmission dynamics of Borrelia turicatae from the arthropod vector.

PLoS Neglected Tropical Diseases, 2014
BackgroundWith the global distribution, morbidity, and mortality associated with tick and louse-borne relapsing fever spirochetes, it is important to understand the dynamics of vector colonization by the bacteria and transmission to the host.

Long‐term stability of conventional non‐regenerative periodontal treatment for furcation defects

Periodontology 2000, EarlyView.
Abstract Background Furcation involvement (FI) in multi‐rooted teeth poses significant challenges in periodontal therapy due to complex anatomy and difficulty in achieving effective maintenance. FI is associated with increased periodontal destruction, especially in sites with narrow furcation entrances and deep root concavities.

Enhanced Adhesion and OspC Protein Synthesis of the Lyme Disease Spirochete Borrelia Burgdorferi Cultivated in a Host-Derived Tissue Co-Culture System

Balkan Medical Journal, 2013
Background: The adhesion process of Borrelia burgdorferi to susceptible host cell has not yet been completely understood regarding the function of OspA, OspB and OspC proteins and a conflict exists in the infection process. Aims: The adhesion rates of

Novel and emerging antimicrobial strategies in the management of oral infections

Periodontology 2000, EarlyView.
Abstract Background Antibiotics marked a pivotal turning point in human civilization, enhancing social interactions and extending human life expectancy. In addition to their success in treating systemic infectious diseases, they have significantly improved periodontal treatment outcomes as an adjunct therapy.

Long‐term periodontal and peri‐implant tissue stability under supportive therapy

Periodontology 2000, EarlyView.
Abstract Background Supportive periodontal and peri‐implant maintenance therapy is strongly associated with improved long‐term retention and stability of natural teeth and dental implants. Lack of regular professional follow‐up after initial therapy is a major risk factor for disease recurrence and tooth or implant loss.

Revisiting oxygen toxicity: evolution and adaptation to superoxide in a SOD-deficient bacterial pathogen

mBio
Dioxygen (O2) is vital for aerobic life, but its utilization leads to the inevitable production of superoxide, a toxic oxidant. The prevailing theory of oxygen toxicity postulates that superoxide-scavenging enzymes (SOSEs), such as superoxide dismutases (
