Spirochetes are not sufficient to cause tumorigenesis.

, 2020
(A) Presence of some bacteria on Hydra is necessary for T. parva to colonize the host. T. parva injected into antibiotic-treated polyps free of bacteria were not able to settle, and neither of injected polyps (0/158) developed tumorous phenotype.

Association Between the Root Canal Microbiome and Apical Lesion Size: An Observational Shotgun Metagenomic Study

International Endodontic Journal, EarlyView.
ABSTRACT Aim The aim was to characterize the taxonomic and functional composition of the microbiome involved in primary endodontic infections and to evaluate their association with the periapical lesion size using shotgun metagenomic sequencing. Methodology Samples from primary root canal infections diagnosed with apical periodontitis were analysed ...

Nitrogen Fixation by Symbiotic and Free-Living Spirochetes

, 2001
Spirochetes from termite hindguts and freshwater sediments possessed homologs of a nitrogenase gene (nifH) and exhibited nitrogenase activity, a previously unrecognized metabolic capability in spirochetes.

Differential Risk for Lyme Disease along Hiking Trail, Germany

Emerging Infectious Diseases, 2011
To estimate relative risk for exposure to ticks infected with Lyme disease–causing spirochetes in different land-use types along a trail in Germany, we compared tick density and spirochete prevalence on ruminant pasture with that on meadow and fallow ...

Phylogenetic analysis of the spirochetes [PDF]

Journal of Bacteriology, 1991
The 16S rRNA sequences were determined for species of Spirochaeta, Treponema, Borrelia, Leptospira, Leptonema, and Serpula, using a modified Sanger method of direct RNA sequencing. Analysis of aligned 16S rRNA sequences indicated that the spirochetes form a coherent taxon composed of six major clusters or groups. The first group, termed the treponemes,

Vectors and Vector‐Borne Diseases: Biology, Epidemiology and Integrated Control Strategies

Journal of Applied Entomology, EarlyView.
ABSTRACT Vector‐Borne Diseases (VBDs), transmitted by arthropods such as mosquitoes, ticks, fleas and sandflies, represent a significant threat to global health. These diseases can be caused by a variety of pathogens, including bacteria, viruses, protozoa, and helminths.

FcpB Is a Surface Filament Protein of the Endoflagellum Required for the Motility of the Spirochete Leptospira

Frontiers in Cellular and Infection Microbiology, 2018
The spirochete endoflagellum is a unique motility apparatus among bacteria. Despite its critical importance for pathogenesis, the full composition of the flagellum remains to be determined. We have recently reported that FcpA is a novel flagellar protein

A Multifunctional β‐Defensin‐3 Mimetic Peptide Modulates Host–Biofilm Interactions and Reduces Bone Loss in Periodontitis

Journal of Periodontal Research, EarlyView.
BDMP, a peptide that can penetrate cells and tissues, offering antimicrobial and anti‐inflammatory effects, has been identified as a potential new therapy for periodontitis. ABSTRACT Aim This study evaluated the potential of a beta‐defensin‐3 mimetic peptide (BDMP), a synthetic cell‐penetrating peptide with antimicrobial and immunomodulatory properties,

Spirochetes form blebs before death.

, 2013
ΔrpoS/rpoSin spirochetes were induced with IPTG at a final concentration of either 0 or 1.0 mM for 3 days and imaged using the Polara G2 electron microscope.

Isolation and cultivation of Lyme disease spirochetes. [PDF]

, 1984
The successful isolation and cultivation of Lyme disease spirochetes traces its lineage to early attempts at cultivating relapsing fever borreliae. Observations on the growth of Lyme disease spirochetes under different in vitro conditions may yield ...
