Unraveling the oral microbiome's role in Alzheimer's disease: From pathophysiology to therapeutic potential

open access: yesAlzheimer's &Dementia, Volume 21, Issue 12, December 2025.
Abstract Oral dysbiosis contributes to Alzheimer's disease (AD) by promoting neuroinflammation. Pathobionts such as Porphyromonas gingivalis, Treponema denticola, and Fusobacterium nucleatum release virulence factors that induce amyloid beta aggregation and tau hyperphosphorylation, while the loss of commensals like Streptococcus salivarius and ...

Insights into aerobic microbial community in the Kamniška Bistrica river sediment with culture-dependent and molecular biology approach

open access: yesActa Agriculturae Slovenica, 2014
River systems are exposed to anthropogenic disturbances, including chemical pollution and eutrophication. They may affect a structure and diversity of microbial communities in river sediment.

Resolving environmental drivers of microbial community structure in Antarctic soils [PDF]

open access: yes, 2009
Antarctic soils are extremely cold, dry, and oligotrophic, yet harbour surprisingly high bacterial diversity. The severity of environmental conditions has constrained the development of multi-trophic communities, and species richness and distribution is ...

Genetic Confirmations of Dwarf Lemurs Across Madagascar Highlights Complex Biogeographic Patterns 马达加斯加全境鼠狐猴的遗传确认揭示了复杂的生物地理模式

open access: yesIntegrative Conservation, Volume 4, Issue 4, Page 665-674, December 2025.
Using a diagnostic mitochondrial marker gene, we document the presence of furry‐eared dwarf lemurs, a species known from Madagascar's eastern montane rainforests, in several forest fragments across the island's central highlands. These findings raise new questions about when this species colonized these sites, how they tolerate these changing and ...

Lurking in the leaves: How large native trees and leaf litter promote amphibian diversity in Malagasy agroforests

open access: yesJournal of Applied Ecology, Volume 62, Issue 12, Page 3395-3407, December 2025.
While old‐growth forests are irreplaceable for conserving Madagascar's endemic amphibian diversity, agroforests can also support amphibian populations, especially if management enhances habitat complexity through increased leaf litter and the presence of large native trees.

The impact of different DNA extraction methods on the analysis of microbial diversity of oral saliva from healthy youths by polymerase chain reaction-denaturing gradient gel electrophoresis

open access: yesJournal of Dental Sciences, 2016
Background/purpose: Polymerase chain reaction-denaturing gradient gel electrophoresis (PCR-DGGE), as a conventional molecular technique, was utilized to analyze the diversity of oral microbiota.

Percent‐Level Copper Mineralisation Promoted by Copper‐Tolerant Iron‐Oxidising Bacteria in Circumneutral Mine Drainage

open access: yesEnvironmental Microbiology, Volume 27, Issue 12, December 2025.
A neutrophilic Fe(II)‐oxidizing Gallionellaceae was isolated from circumneutral Cu mine drainage. It mediated Fe(III) biomineralization, resulting in pronounced Cu accumulation (up to 2 wt%) within the solid precipitates. ABSTRACT Geomicrobiology of copper (Cu) and iron (Fe) in circumneutral‐pH drainage from a Japanese Cu mine was investigated, with a ...

Assessment of the microbial communities associated with white syndrome and brown jelly syndrome in aquarium corals [PDF]

open access: yes, 2013
Bacterial and ciliate assemblages associated with aquarium corals displaying white syndrome (WS) and brown jelly syndrome (BJS) were investigated. Healthy (n = 10) and diseased corals (WS n = 18; BJS n = 3) were analysed for 16S rRNA gene bacterial ...

The Microalga Chlorella vulgaris Supplements as a Factor Increasing the Survival of Potentially Probiotic Lactic Acid Bacteria Under Environmental Stress Conditions

open access: yesEnvironmental Microbiology Reports, Volume 17, Issue 6, December 2025.
Chlorella vulgaris supplementation enhanced the growth and survival of lactic acid bacteria under acidic and bile stress, confirming its protective role. These findings highlight the potential of C. vulgaris as a functional additive to improve probiotic viability in food applications.
