New virus-like agents identified in human gut and oral microbiotas

Researchers have identified a new class of virus-like agents known as "obelisks" in oral and stool samples from hundred of people.

The development of the infant oral microbiome: understanding the role of Archaea and obligate anaerobes

Microbiomepost conducted an exclusive interview with Charlotte Neumann, researcher at Medical University of Graz, about the role of Archaea and obligate anaerobes in the development of the infant oral microbiome.

Mouth bacteria speed up pancreatic cancer growth in mice

Research done in mice shows that the mouth-dwelling bacterium Porphyromonas gingivalis can travel from the mouth to the pancreas, resulting in lesions that lead to cancer.

How sugar changes the metabolism of cavity-causing bacteria

The findings suggest that lysine lactylation contributes to metabolic regulation in bacteria and that GNAT13 may limit sucrose-driven biofilm formation.

The mouth microbiota may forecast the recurrence of oral cancer

The findings of a recent study suggest that the composition of the mouth microbiota can be used to predict the recurrence of oral cancer.

A new mechanism in rheumatoid arthritis aggravation: Fusobacterium Nucleatum-mediated release of FadA-containing outer membrane vesicles

The findings of a recent study imply that Fusobacterium nucleatum may play a causal role in worsening RA, offering potential therapeutic targets for effectively alleviating RA symptoms.

Cocaine users have disrupted gut and oral microbiotas

Cocaine users have an altered gut and oral microbiota composition and function, which can be rescued by rTMS-induced cocaine abstinence.

Healthy humans do not have a common blood microbiota

The findings suggest that microbes can occasionally enter the bloodstream from other body sites without causing disease, but they do not support the idea of a common blood microbiota.

Mouth bacteria may trigger rheumatoid arthritis flare-ups

The findings of a new study suggest that periodontal disease may contribute to rheumatoid arthritis by triggering specific immune responses.

Microbiotas are transmitted between people that spend time together

A recent study suggests that people who spend time together share similar gut microbiotas — with some microbes being largely transmitted between friends and relatives.
