Motility and Ultrastructure of Spirochaeta thermophila [PDF]

Frontiers in Microbiology, 2016
We analyze here for the first time the swimming behavior of a thermophilic, strictly anaerobic Spirochete, namely Spirochaeta thermophila using high temperature light microscopy. Our data show that S.

Exploring the Microdiversity Within Marine Bacterial Taxa: Toward an Integrated Biogeography in the Southern Ocean [PDF]

Frontiers in Microbiology, 2021
Most of the microbial biogeographic patterns in the oceans have been depicted at the whole community level, leaving out finer taxonomic resolution (i.e., microdiversity) that is crucial to conduct intra-population phylogeographic study, as commonly done ...

Geographically driven differences in microbiomes of Acropora cervicornis originating from different regions of Florida’s Coral Reef [PDF]

PeerJ, 2022
Effective coral restoration must include comprehensive investigations of the targeted coral community that consider all aspects of the coral holobiont—the coral host, symbiotic algae, and microbiome.

Species and functional composition of cecal microbiota and resistance gene diversity in different Yunnan native chicken breeds: A metagenomic analysis [PDF]

Poultry Science
The gut microbiota of chickens not only modulates host immune function and production performance through nutrient metabolism but also serves as a reservoir for antibiotic resistance genes (ARGs), whose accumulation exacerbates bacterial resistance. This

Spirochaeta Pallida or Treponema Pallidum? [PDF]

Journal of the American Medical Association, 1916
To the Editor: —Your editorial comment on this question (The Journal, Nov. 25, 1916, p. 1607) is in error. Schaudinn originally placed the Treponema pallidum in the genus Spirochaeta . It was only after he discovered that it did not belong to that genus that he named a new genus, Treponema Both your editorial writer and Dr.

PIP2 inhibits pore opening of the cyclic nucleotide-gated channel SthK [PDF]

Nature Communications
The signaling lipid phosphatidylinositol-4,5-bisphosphate (PIP2) regulates many ion channels. It inhibits eukaryotic cyclic nucleotide-gated (CNG) channels while activating their relatives, the hyperpolarization-activated and cyclic nucleotide-modulated (

Spirochaeta recurrentis: A Filter Passer

The Journal of Parasitology, 1920
Spirochaetes in an infective form can be forced through a Berkefeld filter by pressures of 50 pounds, and over, to the square inch (Todd and Wolbach, 1914). This note records an endeavor to ascertain the form in which Spirochaeta recurrentis passes through the filter.

Differential Signature of the Microbiome and Neutrophils in the Oral Cavity of HIV-Infected Individuals

Frontiers in Immunology, 2021
HIV infection is associated with a wide range of changes in microbial communities and immune cell components of the oral cavity. The purpose of this study was to evaluate the oral microbiome in relationship to oral neutrophils in HIV-infected compared to

Effects of hydraulic retention time and influent nitrate concentration on solid-phase denitrification system using wheat husk as carbon source [PDF]

PeerJ, 2023
Solid-phase denitrification shows promise for removing nitrate (NO3−-N) from water. Biological denitrification uses external carbon sources to remove nitrogen from wastewater, among which agriculture waste is considered the most promising source due to ...

Description of Oceanispirochaeta crateris sp. nov. and reclassification of Spirochaeta perfilievii as Thiospirochaeta perfilievii gen. nov., comb. nov.

International Journal of Systematic and Evolutionary Microbiology, 2020
A novel obligately anaerobic spirochete strain K2T was isolated from bottom marine sediments at Crater Bay of Yankicha Island (Kuril Islands, Russia). Strain K2T had helical shape and Gram-negatively stained. The optimal growth conditions were as follows:
