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.

Motility and Ultrastructure of Spirochaeta thermophila
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.

Mechanism of lipid-dependent cold sensitivity in a model ion channel [PDF]
Nature CommunicationsTemperature sensing enables organisms to detect and respond to environmental changes. While temperature-responsive ion channels are key to this process, the physico-chemical mechanisms by which they sense temperature remain poorly understood.

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

SPIROCHAETOSIS IN YOUNG FAYOUMI CHICKS [PDF]
Assiut Veterinary Medical Journal, 1987 Experimental spirochaeta infection was done in Fayoumi chickens of different age (3-7 weeks old). It was proved that the young chicks were susceptible to infection. Pathological examination revealed that the spleen was the principle organ mostly affected

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 ...

Prolyl isomerization controls activation kinetics of a cyclic nucleotide-gated ion channel
Nature Communications, 2020 SthK, a cyclic nucleotide-gated ion channel from Spirochaeta thermophila activates slowly upon cAMP increase. Here, authors investigate cAMP-induced activation in purified SthK channels using stopped-flow assays and enzymatic catalysis and reveal that ...
