Identifizierung der endo- und ectosymbiontischen Bakterien und cellulolytischen Aktivitäten der symbiontischen Flagellaten der australischen Termite Mastotermes darwiniensis [PDF]

open access: yes, 2008
The lower wood-feeding Australian termite Mastotermes darwiniensis Froggatt (Fig. 1) is the only living member of the family Mastotermitidae. The complex symbiotic hindgut flora consists of protozoa (formerly named Archaezoa; Cleveland & Grimstone 1964 ...

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

open access: yesPeriodontology 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.

Typing African Relapsing Fever Spirochetes

open access: yesEmerging Infectious Diseases, 2005
Relapsing fever Borrelia spp. challenge microbiologic typing because they possess segmented genomes that maintain essential genes on large linear plasmids. Antigenic variation further complicates typing.

Active invasion of Porphyromonas gingivalis and infection-induced complement activation in ApoE-/- mice brains [PDF]

open access: yes, 2014
Periodontal disease is a polymicrobial inflammatory disease that leads to chronic systemic inflammation and direct infiltration of bacteria/bacterial components, which may contribute to the development of Alzheimer’s disease.

Protein Secretion in Spirochetes [PDF]

open access: yesMicrobiology 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 ...

Novel and emerging antimicrobial strategies in the management of oral infections

open access: yesPeriodontology 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.

Hide and seek: how Lyme disease spirochetes overcome complement attack

open access: yesFrontiers in Immunology, 2016
Overcoming the first line of the innate immune system is a general hallmark of pathogenic microbes to avoid recognition and to enter the human host.

Arthritis Is Developed in Borrelia-Primed And -Infected Mice Deficient of Interleukin-17 [PDF]

open access: yes, 2016
Interleukin-17 (IL-17) has been shown to participate in the development of Lyme arthritis in experimental mice. For example, neutralization of IL-17 with antibodies inhibits induction of arthritis in Borrelia-primed and -infected C57BL/6 wild-type mice ...

Artificial Irrigation Impacts the Seasonal Occurrence of Pathogenic Leptospira in Its Wild Reservoirs in a Mediterranean Environment

open access: yesZoonoses and Public Health, EarlyView.
ABSTRACT Background Human activities play a significant role in the emergence of infectious diseases. We aimed to test whether artificial irrigation affects the occurrence of a zoonotic bacteria sensitive to desiccation, pathogenic Leptospira species (pathoLep), in micromammals inhabiting Mediterranean ecosystems.
