Sharing more than friendship - nasal colonization with coagulase-positive staphylococci (CPS) and co-habitation aspects of dogs and their owners [PDF]

, 2012
Background Since the relationship between dogs and their owners has changed, and dogs moved from being working dogs to family members in post-industrial countries, we hypothesized that zoonotic transmission of opportunistic pathogens like coagulase ...

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

Alzheimer'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 ...

Gut Microbiota and Bacterial Extracellular Vesicles: Emerging Roles in Myocardial Remodelling and Cardiac Health

Journal of Extracellular Biology, Volume 4, Issue 8, August 2025.
The gut microbiota is capable of secreting bacterial extracellular vesicles (BEVs), which can carry cytoplasmic components, including enzymes and nucleic acids. BEVs have the ability to penetrate the intestinal epithelial barrier, enter the circulatory system and ultimately reach the heart.
